Users site know well that from the reliable and uninterrupted work of all engineering systems Residential building largely depends the comfort of living outside the city. Take on the management of the cottage, having lost its owner from solving routine issues can system "Smart Home". In our article, we have collected expert answers to the most common questions about it.
From our article you will learn:
To understand what is a smart home and how it works, you can read a description of this concept in Wikipedia, and it is better to understand the purpose of this technology along with our experts.
This is how the definition of the company gives "Smart Cottage" Ilya Kovalchuk :
- "Smart Home" is a system built on the basis of high-tech equipment. The main purpose is the automation of operations on the management of various engineering systems in the cottage.
It provides comfort, safety, resource saving and can "take" routine operations on yourself, freeing the hosts of the cottage from these actions.
And here is the definition of the company's development director Luxury Systems. Ekaterina Korolev :
– « Smart Home "is a centralized electrical appliance control system and engineering equipment. And the modes of operation of some nodes, one way or another, depend on the work of others.
Thus, the smart home technology provides for an integrated approach.
Here is the definition of the head of the company's power supply system GWD Engineering Ilya Markov:
- Under this term, usually understand the integration of systems, equipment and nodes into a single intelligent cottage management system.
Namely:
Control over the operation of all systems can be carried out remotely - using a mobile phone, tablet or via the Internet.
General Director of the company Alef Elektro (Moscow) Andrei Nazarenko :
- It is best illustrated by the following example: with the help of a mobile phone or tablet you can: 
The same can be done by means of a special control panel - a button or sensory.
Ilya Markov:
- We can say that the "smart home" is based on three basic principles:
Ekaterina Korolev :
- There are two varieties of systems:
In a residential building there is protection against water leakage and a smoke sensor that sends SMS. This is two different systems, And each of them is responsible for their narrow circle of responsibilities.
Ekaterina Korolev :
- It is impossible to name this "smart home", as it is impossible to control these sensors from a single window interface. Each of these devices have their own parameters and settings, and they work independently of each other. A smart home provides complete coordination and management of all engineering and electrical equipment.
The technology is managed by an intellectual program, and its work is adapted to a specific cottage and owner preferences. For clarity, all available information about its operation is displayed on the sensor display located on the wall. Thanks to an intuitive interface, command names and explanatory images, the management of the Smart House system reminds work on the electronic tablet.
According to Ilya Kovalchuk, The minimum set of equipment, first of all, should ensure security, the ability to remotely monitor the cottage using video surveillance or signaling and motion sensors, as well as the ability to control heating. Thus, the technology will keep away from theft and abnormal situations.
Andrei Nazarenko :
- If the system can independently change its status, then it can be considered smart.
The main appointment of technology is to increase the level of comfort. This includes the convenience of control: the illumination of the room, minimization of the technician control panels, the optimal work of all engineering cottage systems in order to save energy.
Warm floors that are disconnected for a whole day when you go to work, and turn on an hour before your return, thereby saving energy, you can call "smart" warm floors.
Ekaterina Korolev :
- There is a package of minimal functions, in which the system has the right to be called a "smart home". It includes two or more functions that can be controlled from one interface:
Ilya Kovalchuk :
- The "smart home" is called the simplest monitoring and management systems: GSM sockets, units for freelance situations. In my opinion, this can be called any scheme of management or monitoring, built on the basis of high-tech equipment, which brings real benefits to its owner.
Modern technologies and materials provide the possibility of gradually increasing the functional, which allows you to start with small, and subsequently create a complex and multifunctional automation system.
Ilya Kovalchuk :
- One controlled outlet (which enabled a heater) "smart home" can be called with a large stretch, but someone can really ease life, save electricity costs, help make your life more comfortable even in the apartment. In the future, it can be part of a more complex scheme.
Such flexible customizability allows you to implement any decisions.
Ekaterina Korolev :
- Features are endless. The functionality can limit only fantasy. Simply put, all the devices that have the "On" button or "off" - You can automate.
Ilya Kovalchuk :
- There is an Internet in the cottage, an "smart home" controller is installed and several temperature and movement sensors. Even such a minimum system notifies the user about the invasion of his housing, directing it to the phone signal: SMS notification. Also, the system includes control of the temperature and humidity in the house.
Next, adding socket modules (smart sockets or installing the relay), it is possible to automatically - on schedule or some events, control electrical equipment, control the degree of lighting. Depending on the room temperature, include individual heating devices, air conditioning, supporting a comfortable atmosphere. Moreover, in the presence of a multitariff counter, as well as in the absence of owners, it can be saved on electricity.
Ilya Kovalchuk
:
- going to the cottage, you can in advance, through the phone, Internet, etc. Install a comfortable temperature. For security, at any time you can add fire sensors, water leakage sensors, gas leaks.
Subsequently, on the triggering of such sensors, the water and gas overlap can be organized.
You can expand the system almost infinitely.
With the help of a "smart home" you can:
The light can be lit, reacting to the approach of people, and disconnect when removing them.
The picture can be transmitted in real time to the phone, tablet or laptop screen.
Due to the inclusion and shutdown of light, the lifting and lowering of the roller shutdown is created by the visibility of life, which can scare the thieves in the event of a long lack of hosts.
All this can be managed by remotely, from any devices, and receive any notifications about the operation of systems.
Ilya Kovalchuk :
- There are many systems and protocols intended for the implementation of "smart homes". In fact, you can use any protocol intended for automation. From industrial protocol RS-485 to normal Wi- Fi.
At the moment, the most in demand is the management protocols, intended for home automation and, mostly, wireless, that is, not requiring gaskets of a large amount of wires, global changes in electrical wiring, etc.
The base for a smart home can be the usual personal computer, and many controllers are devices with Linux family systems.
Andrei Nazarenko :
– Optimal option Building a "smart home" - when all devices exchange data on cable using a protocol KNX.
KNX is a single unified International Data Example Standard for automated systems Control.
Many developers put the cable in advance in the walls. In the future, this ensures the possibility of mounting the equipment without expensive alterations of the finished interior.
Ekaterina Korolev :
– The main requirement for equipment is its reliability. The equipment should also be flexible for programming, functional and have an acceptable cost.
If you plan to use the smart home in your cottage, then it is necessary to think about it even when designing all engineering systems.
The installation process of the system is divided into the following steps:
You can equip the "Smart Home" system any dwelling using the equipment that works on the radio channel. But such equipment does not give 100% warranty of the team execution. And if the owner wants to automate the object after repair, then you can hide all communications in a false-brake or to the floor.
Because "Smart Home" depends on electricity, special attention should be paid to the installation of the power grid.
Ilya Kovalchuk :
- All equipment needed to create "smart homes" is intended for standard networks in 220 V. Thanks to wireless equipment, the "smart" can already be done by any existing cottage, especially unwarming its wiring, without repair and changes in the design of the premises, etc. .
Any housing begins with security, so his electrician should be "smart". It is all important - the correct calculation of the cross section of the wires, the presence of Uzo or differential machines, grounding.
Ilya Kovalchuk :
- Considering that the "smart socket" is not much more expensive than the usual modern outlet, including the cost of its installation, then, creating a "smart home" from scratch and in advance of the project, the cost of automation can be reduced, and energy savings will quickly pay off rise in price.
Disarming, whether it will be necessary because of the energy consumption of the "Smart Home" system to receive the worshiped amounts of electricity bills at the end of the month.
Ilya Kovalchuk :
- One of the main destinations of the Smart Home system is the economy of energy resources. Control equipment, sensors, actuators are low-current and consume a minimum of electricity.
In terms of energy consumption, expenses are insignificant, and savings can be multiple. Competently spent and reliable electrician is an already element of a smart home. Smart Home systems can work more than many other household electrical appliances.
Any of the country residents came across the situation of turning off the light, and it is not clear what to do in this case.
Ekaterina Korolev :
- In cases of light disconnection, the system automatically goes into emergency operation. References are recorded from all sensors, and when the electricity is supplied to 100% volume, everything returns to the "as before the disconnection".
Imagine that the light turned off in the cottage. In this case, the smart home system will notify you about what has been shutdown. If there is no one at home, the system will send SMS and will call the user to the mobile phone itself. On batteries uninterrupted power The system will continue to work and maintain the main consumers of electricity: refrigerator, heating system, emergency lighting, security systems. In the event of a long lack of electricity, the system automatically starts the generator.
Ilya Kovalchuk :
- To ensure the performance of all eliminations: the Internet, video surveillance, sensors and actuators, a fairly good computer uninterruptible power supply.
Because All the equipment of the "smart home" refers to the form of low-current, monitoring and feedback with it in this case will continue. The owner of the cottage learns about the disconnection of electricity, non-working heating, other freelance and emergency situations, etc.
Given the features of our power supply, it is advisable to put voltage stabilizers. This is necessary for the normal operation of ordinary electrical appliances.
Power supply systems may include uninterrupted power supply for electricity disconnection. This can be like generators, with auto-start and without, integrated into the general circuit of electricians or simply allowing to exploit the minimum number of electrical appliances. It can also be more complex and expensive uninterrupted power supply systems based on inverters and batteries.
Such systems provide the entire building of electricity to days or more.
From voltage jumps, pulse interference electrical appliances and other equipment can protect differential machines, network filters, protective shutdown devices.
Ilya Kovalchuk :
- To increase the autonomy of housing, you can divide the consumers of electricity into two groups - important ( boiler equipment, refrigerator, alarm, etc.) and secondary. In case of disconnection of electricity, the automation itself will turn off the part of less significant electrical appliances, feeding from the generator only the most important electrical equipment.
Each country owner wants all investments in the housing to work out 100%. And in order to understand how the smart home system works and how it can save funds, an integrated approach is necessary.
Ilya Kovalchuk :
- If you have a heating control in the system of "smart home", then the system can pay off for one heating season.
Payback of other systems – Protection, fire-fighting sensors, water leak control systems, gas leaks, pipe freezers – In such cases is also obvious.
Ekaterina Korolev :
- The system will pay for itself completely at the same moment when it will prevent emergency, fire, flooding, gas leakage, penetration of outsiders to the object, etc.
Also, using automation, you can remotely monitor the housing while on vacation, with the possibility of controlling devices, light, climate from any mobile device or PC.
By summing up the article, we can say that using "smart home» you constantly keep your hand on the pulse of your cottage.
Today there are many elements of the electricity control system - a variety, temperature sensors, movement and sound. In a single bundle with an internal wiring house or apartment, they are able to automate the processes on / off light, heating, control the operation of some household appliances Taking into account time regimes. But it will not be a centralized management system, that is, you will not be able to control light and other consumers from a single device.
The same system is a smart home, because using it you can manage all the consumers connected to the wiring, using one device - mobile (tablet, smartphone, remote control) and / or stationary (computer / laptop, graphical system interface). In this case, all sensors and relays are also present in the system and produce power control automatically.
In addition to elementary household consumers, the intellectual (intelligent) house can monitor and control over communication systems, fire extinguishing, security alarms, phone lines and many others, including engineering communications.
However, for complete control of household appliances, such as adjusting the air conditioner or refrigerator modes, in the instruments themselves there must be a special connector, by means of which the control system is connected to the electronic logical controller. Next, consider those foundations that will give you the concept of a smart home system, its principle of operation and composite elements.
First of all, it is worth noting that today a lot of modifications and completeations appeared, in which the management system of the smart home can be performed. Many manufacturers provide system kits with built-in Wi-Fi and / or Bluetooth transmitters (communication modules), sewn to the controller, by means of which can be controlled by a wireless system through a mobile device within the apartment / home.
A variety of system architecture smart home
There are modifications in which the control occurs through the Ethernet interface (wired method, through); These additionally need to connect switches and Wi-Fi routers for wireless control if they are not embedded in the controller. As for manual switches, they can also be connected to a central controller with a wireless way or via wiring. In general, there is a variety of equipment for the smart home system, and the system consists of such elements:
When choosing equipment is also important to consider which protocol (method) of the data transmission of the smart home system is used. For example, the common EIB \\ KNX protocol uses computer networks, radio channels, power electrical networks as data transmission. There is a X10 protocol that uses a dock 230 V dataset to transmit data: the devices are exchanged by the signal filed at the time of the alternating current through the zero value. Such signals are radiofrequency pulses of 120 kHz, duration of 1 ms.
The controller of the smart home is a device that manages all consumers, devices, and also sends a report to the owner of the state of these consumers. Guided by temperature, air, light sensors for controlling lighting systems, heating, air conditioning. It can be programmed to perform various actions over time, according to temporary schedule. In addition to the autonomous mode, you can contact the controller through a special interface (computer network, mobile operator or radio network), and manually control the instruments.
Devices controlled by the system controller Smart home
Select the controller must depend on how you wish to build a control system architecture. For example, there are two varieties of the control system: centralized and decentralized. The centralized management system is based on the only high-performance central controller, which manages all consumers (devices) and engineering networks in the house.
In the case of decentralized management, the intellectual system of the smart home consists of several simpler controllers, each of which carries the functions to control a certain zone - room and all the devices in it, separately by the lighting groups in the whole house defined by household appliances, etc. ( Regional controllers).
Central controller For the system, the smart home of the modern sample is a computer enclosed in a small plastic case having its own OS (operating system), RAM and a plurality of electronic switching components (control) signals: electronic relays, territorial keys, etc.
One of the components of the Central House Controller of the Smart Home system (on board the wireless transmission module, USB, COM, Ethernet ports)
Also, depending on the configuration, there can be a built-in GSM module for remote control via a mobile phone, a Wi-Fi transmitter to control the system from anywhere at home and a graphic touch or push-button interface (LCD screen). In addition, connectors for connecting to a computer and / or network hardware: Ethernet, USB.
Such a controller is able to control intellectual techniques, like refrigerators, microwaves, engineering communications, etc. (if such a function is provided in the technique), reporting the owner even data as the temperature in the refrigerator, the input and output calls of the telephone line and much more.
Regional controller The discrete I / O modulator is a low-power logical electronic control unit, which implements a smart home technology (to comparison, the frequency of the CC microprocessor is about 500 MHz, the RK is about 50 MHz), as a rule that does not have the operating system and customizable system. It can be configured to any elementary time scenarios or on signals of certain sensors.
Programmable System Controller Smart Home with Interface (Speed \u200b\u200bFor Connection to Network) Ethernet
It leads elementary tasks and events. For example, the light sensor connected to it gives a signal (upon the occurrence of darkness); The controller applies a signal to an actuator or a group to control the lighting. He also notifies the owner of each action. In other words, the discrete I / O modulator is a kind of intelligent programmable electronic relay.
It consists of such a device from the electronic components of the network switching and the intellectual part: microprocessor with memory. It (depends on the manufacturer and configuration) can be USB, Ethernet interface and other ports for managing, programming and providing owner reports.
Expansion modules are devices connected to the controller and expanding its functionality. Partly adapters, bore-breakers and measuring instruments are also an expansion modules. Such devices can be embedded in the controller connected separately through a specially intended connector or a common Ethernet connector, USB and other interfaces. Due to the fact that the company manufacturers of systems intelligent house use various systems Data encryption, when the expansion module is selected, it is important to draw attention to its compatibility if the controller is purchased by another manufacturer.
Right - System Controllers Smart House with built-in wireless data transmission modules
Communication expansion modules For the system, a smart home is a data transmission device with a wireless or wired method. First include all known Wi-Fi routers that are connected to the controller as well as to a computer, via Ethernet or USB (there are specially "sharpened" branded modules with their connection system). More easily, separately connected GSM / GPRS modules are used (since they are usually built), with which the smart home system can communicate with the owner via SMS alerts on its phone number. There are Bluetooth wireless communication modules (radio signals) and IR (transmission by infrared beam).
GSM and Wi-Fi wireless wireless modules; Switch for wired network Ethernet
For a wired communication extension, switches are used - devices that are connected to several clients (computers, controllers and other intelligent devices) into one local network. They are needed when a decentralized smart home system is needed when there are several regional controllers, as well as to create a common network with computers and other intelligent devices using the appropriate interfaces. With a large distance transmission distance, special digital amplifiers are applied to gain it - repeaters.
Functionality expansion modules The smart home systems have the most diverse functionality, and, as a rule, are connected to a shared or special interface connector. They expand the list of controller functions, for example, the voice messaging module allows you to manage the system by means of sound (voice) commands. It is also possible to make the management system of the smart home reproduce sound messages (greetings, warnings, congratulations, etc.) on speakers.
Expansion modules for controlling complex mechanisms, stepper motors, etc.
It is also worth noting the expansion of the functionality by means of adapter modules, which can be achieved by compatibility of various device standards. Special control modules are designed to control various specific devices (engines, opening / closing mechanisms of doors, ventilation valves; much more) and switching elements of the electrical circuit. Thus, the smart home controller does not have the power over the power protective machines (traffic jams, circuit breakers), and when the automatic control module is connected to the automatic control module, the function of turning on / off for means of the controller becomes available. To connect to the system of smart home control regulators (dimmers - see below), special extension modules are also required.
Under the concept of switching the electrical circuit, it is necessary to understand the closure / opening of it, as well as regulation of voltage and other parameters of the electric current. Voltage regulators (lighting), converters / transformers, power supplies, circuit breakers and relays - all these switching elements, without which the installation of the smart home system (as well as any electrically conductive system) is performed. They can have built-in protection against network overload and short circuit and are triggered, the erosion chain is thus performing a protective function.
Simple system scheme Smart house with controller, switching elements (control) electrical circuit and elementary consumers (in this case - Lighting lamps)
Automatic switches designed to protect electrical wiring from overload or closure. They are selected by power to which the electrical wiring line is calculated. For the system, the smart home exists both ordinary manual and controlled circuit breakers.
In the image - simple single-pole circuit breakers
The first to have a mechanism in their design, which, when heated, due to overload, opens the circuit, and can also be turned off manually. The controlled automata has a special interface output to the control module through which the main controller and the owner can manage remotely, without looking into the panel at all.
Relay and relay blocks - These are elements of power circuit controls using the resulting signal from the controller. The signal may look as a small power current, as a rule 24 V (again, there is no single standard, there are different systems and manufacturers) or another signal.
In the image - electromagnetic relays for monitoring by one and several lines of power chain
Unlike the circuit breakers, the relay does not have protection and the mechanism of closure / opening of the chain looks opposite: when the control voltage is supplied to the electromagnetic part, the latter acts an anchor and the mechanical influence is closed by the power supply chain contacts (220 V). The most elementary control relay of one power line of the phase has three inputs and one output: zero and electromagnet control phase (24 V), power supply input (220 V) from a protective circuit breaker and output to the consumer.
Voltage regulators (lighting) Used mainly to control the supply of power and voltage for lighting devices. The basis of such regulators is the element of the chain - the retaint, the device for controlling the lighting. For an ordinary power circuit, a mechanism with a slider enclosed into a box with a switches of the switch and also has an ON / OFF function.
Dimmer, manually controlled (right) and remotely (left)
New Sample Management System Smart Home Lighting Groups Conducts a Dimmer device in itself (connected to the controller also through a special control module). This device is designed to manage one or more lighting groups and is controlled using the controller in automatic mode or remotely host, which is convenient. The advantage of the dimmer - through it the controller can control the brightness of the lighting, guided by the data about the level of illumination obtained from the light sensors.
Power supplies, transformers, converters - This is a complex architecture devices that are intended to change the parameters of the electric current if necessary on a particular section of the chain or throughout the chain.
Power supply from 220 V 12 V
Apply them due to the fact that some consumers are designed for other current characteristics, rather than an alternating 220 V / 50 Hz, submitted to everyday life in the CIS and Europe. For example, take the same lighting: there are special luminescent, neon and other high-elective lighting, which work from 10/12/24 in direct current. In order to achieve such characteristics, a power supply unit 220-10V, 220-12V, 220-24V is mounted on the respective section of the chain. Such devices can operate in one mode, for example 220-24V, or in all three above.
These devices are like sense of smell and touch for a person: they give an idea of \u200b\u200bwhat is happening in the environment. Thanks to modern measuring instruments, sensors and sensors (for today, it is very large for today), on the system controller, a smart home receives data on temperature, humidity, illumination degree and atmospheric pressure outside and indoors.
In the picture, sensors with elementary functions
There are control and measuring instruments for monitoring the status of engineering communications: pressure and consumption of water flow and gas leaks with an electronic interface that allows you to transfer this data to the intelligent smart home system that will build reports and send them to the owner.
Sensors and sensors Analog The traditional sample is used as low-voltage current data transmission up to 24 V, as a rule, and the electrical wiring of small cross section as a transmission medium. For example, the most elementary light sensor contains a photocell with an input and output through which the low-voltage current phase passes. This photocell changes the resistance when light hits it, thus issuing various current parameters at different times of the day.
Figure - Elementary analog sensors reacting to household and carbon dioxide
The controller receives these values, processes them and, accordingly, sends a signal to turn on / off the lighting instruments, as well as adjusting the lighting level (with dimmer). Approximately a similar system, only with different working elements, is available in temperature control sensors (based on their data intelligent system smart home controls heating), movement and noise (light, alarm), gas and water leakage (valve control overlapping gas and water) and much more.
Digital sensors and sensors The new generation has advanced functionality and are intelligent devices. For example, modern multifunctional motion sensors are capable of not easy to display data on the controller in two parameters: 1 ("Yes", there is a movement) or 0 ("No", no movement).
Figure - Digital air humidity control sensor
They are able to measure the distance from the sensor to a moving target, block the delay when moving the object and much more. All this is processed by a microprocessor embedded in the sensor and is fed to the controller in the form of digital signals. It is worth distinguishing the sensors from measurement instruments: sensors and sensors flow events, and control and measuring instruments are trapped the physical values \u200b\u200bof the measured body, an object (speed, weight, webly, etc.).
Measuring instruments - These are more complex devices, unlike simple analog sensors, which accommodate new technologies smart home and control a wide range of parameters, provide their physical units of measurement. Digital barometers, water and gas meters, the same voltage - all this control and measuring instruments.
Control and measuring device of temperature and consumption of hot water
Unlike analog instruments and sensors, modern digital, have their own computing system based on simple microprocessor; They process signals and in the finished form give data to the controller of the smart home, thereby partially unloading its processor. As a data transfer medium, digital instrumentation and sensors use a special interface.
The system of intelligent (intelligent) house can be made in three ways: wireless local, remote wireless, wired local, remote wired. Control devices are included with the system - this is a graphical control panel with a touch or a button input, the remote controls with the receivers configured to a certain frequency. Unwoining the device as mobile compact computers (smartphones, tablets) are configured using special software for managing a remote way, through worldwide information networks.
The smart home system can be controlled by a remote control, control panel and mobile devices.
Wireless Local Management Method A limited radius is made using control devices through the local (local) radio signal, Wi-Fi or Bluetooth Wireless radio network. In principle, in this way you can control the system from anywhere at home and even being on panstone nearby. However, in large homes, you may need additional radio lips, wireless signal amplifiers. Control is carried out by consoles, touch panels, mobile devices (smartphones, tablets, laptops), which have a built-in or connected from the outside of the transmitter of a Wi-Fi network, Bluetooth or branded radio frequency signal.
On the tablet screen - software for monitoring indicators and instruments connected to the smart home system
Wireless remote control method Available if an intelligent home system is installed to global networks or communication extension modules that provide access to them. Such networks include GSM / GPRS (mobile communications management), mobile Internet, a special dedicated radio signal. The exit to the GSM / GPRS network allows the system to send SMS, MMS and sound messages to the phone number of the home owner. It is also theoretically controlled through the voice menu. Tools for managing smart home systems through global networks is, as a rule, smartphones, as well as tablets and laptops with built-in transmitter modules for mobile Internet.
Wired Local Management Method Depending on the smart home system data transmission protocols, the smart home can have a twisted pair data environment (computer network cable), electrical wiring (X10 system protocol) or any other cable. In each regional and central controller, the management system of the Smart House provides for a wired communication with control devices, as well as information exchange with other intelligent devices that are in "subordination". If multiple devices, the interface is expanded using a switch (see above "Communication Extensions Modules"), creating several branches. For a wired local control method, you are used in the kit and separate control panels and switches (pushbutton and sensory), and you can also manage a computer or laptop connected to the cable connected to the cable.
Touch control panel Smart home combined with intercom
Wired remote control method Systems of the smart home are the network, size more local, that is, the home management occurs from the outside by the laid cable connected to the internal control network. As a rule, this method of management is applied in the management of automated buildings such as building processes. In general, for home use of this (management of systems through regional conduction networks) is not needed.
In contrast to the relays that partly be called the executive elements (the command - the relay is closed / opening the chain), the executive mechanisms running intelligent equipment for the smart home system are complex electromechanical products, devices designed for testing high mechanical loads.
In the image you can observe objects in which the integrated executive mechanisms of the smart home can be
The working body of more complex devices (opening / closing of the gate, blinds, etc.) is an engine, in less complex (valves, locks) - a core, which is driven by an electromagnet. Most of the low-voltage current up to 24 V inclusive, but there are also high-power drives calculated on 220 V.
Electromechanical opening / closing drives gates, wickets, doors, windows, blinds and curtains; Embedded electromechanical parts that make it motorized. Included, they can have an interface of the connection and remote control.
The girl controls the window mechanism of the smart home with a wireless console
In advanced drive models there are elementary automated control systems: built-in sensors and speed settings and extreme opening / closing positions. Today, there are most often there are autonomous actuators for curtains and blinds that the smart home intelligent system is managed: manageable from the infrared transmitter console, and there are no connection with the controller of the smart home. However, such devices are also considered separate elements of a smart home.
Low, average valves and high pressure - these are simpler mechanisms for controlling water networks (including and fire extinguishing), gas pipes and ventilation. Valves are applied in control systems: gas - gas control systems, water supply control, flooding and fire extinguishing prevention.
In the image - water valve, managed by a smart home system
It is very useful for health, and it is worth noting the system of ventilation valves, which is triggered from carbon dioxide sensors (CO2). The system will weather harmful to humans and creates a favorable microclimate. Such elementary mechanisms include electromagnetic locks and other elements of access control in the security system of the smart home. Such devices mainly do not have microprocessors, have only two positions: open and closed.
The smart home technology is familiar with almost every user of digital devices, so there is no particular sense to talk about the features. Smart home equipment comes in two versions - expensive complex package and in the form of components, in the second case, the system must be collected with their own hands. Consumers who buy a ready-made package may not understand the possibilities, and technically savvy buyers are already well represented by the desired functionality.
In practice, the use of the smart home technology rests on the available equipment and software applications with which you can manage installed system. Our review will be discussed about the components offered in the market, and the price and technical accessibility will be discussed.
Readers can choose between inexpensive equipment providing all the necessary functionality, and more expensive systems, which are distinguished by unfolded functions, high reliability and safety. Both options are available to a wide circle of consumers and do not require enormous investments.
To date, you can choose between the following suggestions:
First we will deal with what to start and how to choose components for your smart home. Note that the system functionality can be expanded as needed in one or another. The necessary and optimal package of equipment allows you to control the lighting and turning on / off the equipment, usually implemented not only from the remote controls, but also the software application installed on the PC database or on the user smartphone.
Objectively, the technique has already become part of our life. Today, speaking about the technology "Smart Home". We are talking about the development of Internet technology (Internet of Thing, IoT). These are devices that can be connected to the Internet via wired and wireless channel, in the second case via Wi-Fi (with an average radius up to 50, depending on the transmitter) or Bluetooth (up to 10 m).
Wi-Fi and Bluetooth are two standard telecommunications standards that differ in a small radius of action and are used in home automation systems. Bluetooth can only be applied if there is no more than 10 m between the control module and the device, and in practice - no more than 3-5 m. The wireless transmission range Wi-Fi depends on the transmitter and specific installation conditions, the radio signal is poorly missed by concrete floors.
Despite enough opportunities, manufacturers are not engaged in the intensive implementation and implementation of such equipment. The main problem is that the ubiquitous use of technology will lead to an increase in the number of IoT devices, which is simply not calculated by the existing Internet infrastructure. As a result of the wishing to establish a "smart home" in their apartment in an apartment, you will have to understand the intricacies yourself, not counting on large manufacturers.
If there is a desire to introduce new household automation solutions with low costs, of course, you need to refer to manufacturers that implement their products on AliExpress. On this portal, there are practically no "smart home with your own hands and how to do" packages, but there is a necessary equipment that is enough for the necessary accommodation of an apartment or at home.
So, the minimum package of equipment that is in China at a very affordable cost and application in the network - let's call it "smart apartment with your own hands" - includes:
An assortment range of equipment is presented to a relay for connecting devices, dimmer load control dimmers (for lighting and electrical installation) and batch systems, including management "climate control", lighting, alarm and sometimes video camera. You can get a complete list of offers by entering the portal of the portal Aliexpress "Smart Home", "Smart House", intellectual House", As well as the names of two Chinese manufacturers Lilovo and Sonoff.
Sonoff releases a Wi-Fi relay for remote control of household appliances from a smartphone. The device is installed on a line with one or more electrical appliances, allows you to turn on and off the power supply from the smartphone using a mobile application.
The advantage of this device is that it is always available online, can be connected via the telephone network (PTSN) and allows you to specify an individual work program using 8 built-in timers. Through the relay you can control the operation of any household appliance with a capacity of up to 2.2 kW using the ewelink mobile application available on Google Play IOS and Android.
Sonoff products are also available in Russia. The price in China is about 6 dollars (without remote control), in Russia - 2000 rubles (with a remote control). The relay is offered in two versions of 10 A and 16 A, in the second case, in addition to all sorts of household appliances, a boiler may be connected to a mobile application.
Similarly, other electropurture models work, allow you to connect several instruments at once, for example, Sonoff Sensor-AM2301. Moreover, control is implemented with different values \u200b\u200bof timers.
The manufacturer produced three models Wi-Fi Sonoff relay:
Sonoff also manufactures sensory-dimensional sensor switches for smooth adjustment lighting devices, which can be connected to Wi-Fi and mobile application.
For devices to be available on the Internet, they need to connect one of the available ways. One of the successful and inexpensive options can be considered a Broadlink home automation router that supports 4 types of Wi-Fi wireless, IR, RF and 4G.
With it, you can connect all the home devices through the SIM card to the mobile Internet. It is better to choose the service of the operator with the new communication infrastructure, in particular, one of the MTS packages with the illicit facility.
Xiaomi releases a range of relays, dimmers, sensors for automation of the house. First of all, it is worth paying attention to Wi-Fi humidity and temperature sensors, door and window, "smart" sockets and inexpensive IP cameras. The equipment of this company features simplicity and pricing access, along with high assembly quality.
The manufacturer launches batch solutions for apartments and small houses is the Xiaomi Smart Home Suite. This package is widely proposed in Russia and refers to the category of equipment "Suite". The price category of these sensors is slightly higher than the devices from Sonoff.
Lilovo touch switches work only with remote controls. Them key feature It is the possibility of smooth lighting adjustment, elegant design and different color solutions. Switches of this company can be used to turn on and off household devices without connecting to the Internet.
In China, you can purchase products of Russian manufacturers carrying out the assembly of electropurtures in the Chinese base. The Russian Wi-Fi Relay SMART Home DC is available at a lower cost than Sonoff, and are considered more reliable and unmistakably catching the signal. Consumer drawback SMART HOME relay in the absence of a plastic case, but it is the easiest, reliable and inexpensive way to integrate household devices.
On Google Play you can download a number of mobile applications for connecting home automation devices, different levels of versatility and stability.
Home automation devices can be connected using local applications based on the PC and in the Cloud. Each of these options is distinguished by a number of advantages. Applications in the "Cloud" are designed for the budget use of the smart home technology with a wide range of functions, however, the security and unauthorized access to home devices remains open in such systems.
Stationary batch offers in a protected cloud environment or for PCs are designed for automation country houses, public buildings and institutions. Such an application guarantees a high level of security and reliability.
Smart Home Applications:
Clouds "Smart Home":
Russian equipment of the company "reasonable house" is characterized by high reliability and quality assembly. The manufacturer offers various electropurtures, sensors, relays to build arbitrarily complex systems using smart home technology with a guaranteed security level. Devices allow you to create home automation systems with an individual set of functions, software software is available for mobile devices, PCs and tablets.
The equipment described by us will create various solutions to automate residential premises and household farms, ranging from low-cost budget decisions for apartments, ending with the full automation of large country houses. It is worth noting that now the web platforms for managing home automation devices are not developed due to the concept of concept.
Buyers are offered to establish local PC-based systems or create private clouds managed by ready-made applications. The user can choose for himself and assemble the most suitable option to automate the apartment or at home.
About how the Belarusian company "Nero Electronics" took up the production of components for a smart home. Decided seriously and even turned to the Lebedev Studio, where they helped with the design of Belarusian devices. The key difference of the system, according to the manufacturer, is that it can be mounted independently without special skills. It is enough to be in the measure of a brutal man who knows how to keep a screwdriver in his hands and cling to the legs behind the stepladder. We decided to experience on ourselves how easy it is or difficult to make an intertarous one today.
To figure out what and why you need, it seems to be simple. It is enough to estimate how many points in the house in the house, after which you can order devices. Be sure to need a server that will be responsible for setting up and manage the smart home from the application. Next - Heap of sensors, consoles and relays. As it turned out, it is necessary to approach the question. We, for example, scored the devices with too large stock. Before switching to the process of learning an apartment with different smart things, first let's see what these devices need.
We will specify that the system supports working with third-party sensors using the Z-Wave Plus protocol with a frequency of 869 MHz. Belarusians have no sensors, the company offers Polish Fibaro. If you wish, you can connect any other sensors with a more humane price.
Server OLEDO 7767 HOST
Almost a reasonable "head" of our house, which combines executors of teams to the network, processes their indicators and allows you to manage the system through the Wi-Fi application or mobile Internet. There is support for GSM - you can install the SMI to send the server to the SMS phone about certain events or received commands through the same Esems on the launch of some action. But messages can come directly into the app, so you can safely do without SMS.
The black box is equipped with a 512 MHz frequency processor, 512 MB RAM and 4 GB Capacity. There is a battery that, according to specifications, allows the device to hold out about 8 hours without connecting to the power grid. The current server is displayed on the screen. It will be useful to find out the source of the problem in the absence of communication with the system.
Opening Sensor Door and Window
Exactly the same or similar sensor we also saw, and y. The essence is simple. In one set there are two cylinders - one is installed, for example, on door leafAnd the second is on the door jamb. The sensors in touch - it means that the door is closed, disconnected - open.
The one is more attached to bilateral sticky ribbon. 3M, and the "baby" can be adjusted to the metal surface of the door frame.
Water leakage sensor
With such a thing, we are also familiar with the time of review of the smart home from Beltelecom. You can place the sensor at the place of potential danger (for example, in the bathroom or in the kitchen). The leakage is determined by closing the moisture of three metal legs. Additionally, the sensor can determine the temperature indoor.
Put and forgot
Sensor of light, temperature and movement
But this "eye" is much more interesting. It is on this thing that many scenarios of the work of the smart home will be tied. For example, when a decrease in the level of illumination relative to a given value can automatically turn the lamp. Rose temperature? Turn on air conditioning. A person came out of the room? Turn off all light sources. All three parameters can and need to combine.
Mashed "Eye" to a plastic arc. It can be hung, for example, somewhere in the corner of the room, after which the sensor is placed there. And you can put on any smooth surface - The frame will be kept thanks to a flat "heel".
Button-remote
Also saw before. Can be remotely and without wires, turn on or off the light or outlet. The device seemed to us a little useful due to the presence of more interesting options Management of a smart home system. But it can be consolidated if you need an imperceptible switch, for example, in the bathroom. Bilateral scotch is attached.
Wall panel OLDO
The same device that we preferred the console button. With the help of a two-channel console, you can turn on-off the light or run and stop executing a scenario. Despite the simple description of the functionality, in fact it is a very pleasant thing that replaces the usual switches. All because OLEDO is not tied to the placement of wiring - it is wireless and can be located anywhere. Although throwing the entire room with such consoles.
There is a soft light indication of the press. The remote control is primed to the flat wall holder, which, in turn, is attached to the wall of two-way scotch.
Portable OLDO remote control
The same beautiful thing as a wall panel, but more advanced. Here you can already manage five objects. For example, a group of lamps in the hall, bedroom, in the kitchen, in the corridor, bathroom and toilet. Initially, the remote is a sticker with prompts. If it is removed, it will remain a beautiful, minimalistic decorated, but not very understandable device. We got used to the location and purpose of the buttons for a couple of days, using tips on the film.
The device is equipped with an accelerometer. When you take a remote control, it automatically highlights the last active channel. The device can be left anywhere - right as a remote control from the TV. But in order to bring a bit of organizedness, the Belarusian manufacturer provided a square magnetic holder. His, as you already understood, you can attach anywhere with the help of a scotch, and then brack the remote. Experimentally it was found that Oledo "Friends" with any metal surfaceEven with the refrigerator.
Remote Control
The remote control without a film
Smart Relay Intro.
That's the most necessary device for the smart home. It is possible to automate the operation of the lamps and sockets. The point is that the device is actually embedded in the available chain, taking control of the power on and off of anything. On the example of the lamp, everything looks like this: the network wires are connected to the intro on one side, and the wires from the chandelier or sconce - on the other. After that, you can control the light source, warm floors and other electrical appliances, both using a wireless console and using the application.
Built-in Remote Oledo
This device is needed in order to save the functionality of the available switches. The fact is that after installing the intro relay, the lamp will stop response to the standard switch - it will be possible to manage only through Lebedev's remote or smartphone. The built-in console is installed in the circuit breaker and connects to it.
In our opinion, so-so device. Still, if we do a smart home, then first of all we count on new ways of management. And the built-in OLDO console actually proposes to keep what we have and so it was. However, in Nero Electronics, it is noted that most people, on the contrary, seek to keep the functionality of the available switches. It is clear if we are talking about ready design repairwhich provided for the presence of a specific type of switches.
Note that all the devices are wireless and communicate with each other by radio channel. It should be greatly eased compared to the usual wired systems. Well, go from the theory to practice.
Setting the sensors and installing the server are pleased with its ease. Remembering experience with connecting a smart home from Beltelloma, first set up for a long and full bug procedure. But no - the server "starts" and finds a network via WPS for a minute.
Similarly, "jump" into the smartphone installed on the smartphone, sensors, consoles, relays and other good. Somewhere you need to consider QR code from the box of the device, somewhere to additionally press the button hidden in the sensor.
But with the installation of people with incorrectly growing hands, problems may arise. In Nero Electronics, it is believed that on the installation of one point at the armhole, an average will take about 7 minutes. It is forced to admit to his own "non-tastens" - in our case, it took more time. No, the same "eye" with motion sensors, temperature and illumination took and put it or suspended where the soul wishes - there are no questions here. Or the opening / closing sensor - glued to the tape and slabs in your hands.
But the relay ... Yes, there is a simple video structure, but in life you may prevent you from the most unexpected circumstances. Stretch ceilings, low growth and small stepladder, no screwdriver desired size, All these tints of the "phase", "land" and "zero" ... And if the wisdom lamp falls with a bunch of "extra" wires, then quite trouble.
True, over time, the necessary "skills" is hammered, and the work is simplified. To automate the first point in the bedroom, I left for 10 minutes. This is taking into account the nuances in the form of a search for a suitable toolkit and finding out the reasons why it did not work the first time. Here we met with an important nuance, referred to above. As soon as you connect the smart Intro relay to the lamp, it will be impossible to control using a conventional switch.
In order to leave the switch functionality, it must be turned off from the power supply and connect to the OLEDO embedded remote control. At first I did it, but then I decided that it was superfluous. Instead, again connected the switch to the power grid and left it in the position. The light did not turn on, but the lamp began to respond to the commands of the smart console and application. Earned automation. That is why the built-in console in our case turned out to be superfluous.
It seems that difficult - take and automate everything around, smart with the house! But for this you have to master the application, and this is not as simple as it seems. The program interface with unusual seems confusing, many actions are scattered along different menus. For example, to configure the operation of the timer relay, you need to go to a separate menu, although, in our opinion, it would be logical to duplicate the same functionality when programming events.
The difference between events and scenarios, administrator and superadeministrator rights is not quite obvious. In all this, it is unlikely that it will be possible to deal with theory - it is necessary to develop wide, but intricate features of the application directly in the process of learning your home. Also does not prevent consult from the manufacturer.
Wishlist
We have standard two-room apartment. Stupid like a plug. The task is to turn a dwelling from a sad cave into a spacecraft who will not be able to fly into space, but at least a little bit simplify our daily life.
By briefly thinking after studying the possibilities of a smart home from "Nero Electronics" it was decided to make the following:
We clarify that the described case of automation of the apartment is not the most ideal for the possibilities. Thus, in the test version of housing there was no air conditioner overlapping electric valves, rolled curtains. Imagine how the curtains themselves are lift and fall depending on the specified threshold illumination value. The same air conditioner can heat or cool the room to the arrival of the host. If there are children, then for them you can install the work of the console, computer and TV on schedule. All this is cool, but we have more trivial tasks.
Improving dreams begin with a hallway. Install the open / closing sensor on the door and slightly. The application is prescribed by condition: if the sensor fixes the opening of the door (while the illumination is below 100 luxury and there is a movement), the lamp turns on. Works! To automatically turn off the light, the timer is installed in the relay settings - 5 minutes. This is more than enough to remove the upper clothes. And it is possible without a timer - configuring automatic shutdown when there are no movements in the hallway.
Light in the hallway is also included when motion is detected, if the illumination is below 100 lux. It turns off if there are no movements.
With the hallway, everything was automated with a bang. With the bathroom it turned out more difficult. We put the second opening / closing sensor. Light light on the opening - Made! But how to repay him when you came out? Extinguish the lamp when closing the door? Then you can not close the door to the bathroom when you go there. Can put a motion sensor? Here it is necessary to make a technical explanation. As soon as the sensor recorded the movement, the next survey of the situation is in 30 seconds. If at this moment you are relaxed lying in the bath, the movement will not be detected and the light will go out.
And what if you program the light turning off, too, to open the door? Perhaps the system will be consistently by chain to execute different commands? That is, first as soon as you open the sash to go to take a shower, the lamp will turn on. And the off command will work off the second time you already go out. Alas, but no - with this scenario, the lamp is successively turned on and immediately turned off when the opening sensor is first triggered.
As a result, such an output was found: when entering the bathroom, the light ignites automatically using the open / closing sensor. But turn off already yourself through the OLDO console.
Very great happened with heating balcony. True, during testing the temperature there did not fall below 19 degrees, so the sake of the experiment was set by a threshold value of 23 degrees. You go to the balcony, the sensor fixes the movement and temperature of 22 degrees - the warm floor is immediately turned on. As soon as the temperature rises to 23 degrees - heating is turned off.
It was thought that the following problem could occur: you are sitting on a balcony at a computer, the temperature got to 23 degrees - the warm floor is turned off, the temperature drops, but the sensor does not catch the movement and you begin to slowly freeze. As practice has shown, it is not very fixed to sit at the computer will not be. Let "Eye" detect you not immediately, but still find, and extra few seconds or even minutes in this case have no meaning - the system will work and will not leave you alone with the windows covered.
It is important to note that the sensor, as in all such systems, responds to domestic animals. So if your cat will look at open balconyThe system will turn on heating for it. And at the end of the month can wait for an unpleasant bill for electricity. If we are dealing with a well-normalized working day, then as an output from the situation, you can specify the schedule for the inclusion of the warm floor. For example, an event does not work on weekdays from 9 to 18 hours.
When automation of the hall, the hall had to compromise again. Turning on the flooring depending on the illumination and when moving works fine. About the automatic shutdown again I had to forget. Imagine you watch TV. On the sofa. Lying or sitting. The movements are really little. In general, everything comes down to the fact that the system will constantly turn on, then turn off the landsrs. They say, the question is solved by installing the second movement sensor at the outlet of the hall, but we have not been able to check it.
Automate the lamp in the bedroom
Additionally, the whole conceived made a smart socket to turn off remotely TV (just to be). All lighting as a separate scenario was tied to a portable console, which was installed from entrance door. Pressed one button before going out - and everything is de-energized. But even if this did not, the status of a smart home can be traced anywhere through the Internet. In the same way, you can manage individual objects.
The ability of a smart home is much more than those we described. We got the impression that the system will more interest the owners large apartments and spacious private houses, stuffed up different kinds of home and climate appliances. Add a couple of cameras for video surveillance here (the Belarusians of the camera do not produce, but there should be almost any model with Wi-Fi), electric drives for rollt or roll curtains and smart relays into each outlet or lamp - and here we have already ready for the ready system.
As for a small urban apartment, the first time the retraining of it in the smart seems to be a contrivedge. But gradually get used to small amenities. For example, we liked to use both wall mounted and portable remote control.
During the testing of a smart home from "Nero Electronics", several features noticed that it is important to take into account. So, the availability of a pet will be an obstacle to creating a simple algorithm. We will have to strain fantasy, to use several sensors at once so that the smart home has fragilate the cat, or carefully look for such an angle of installation, which would not be captured by a pet-squeezed pet.
NeroHome is still damp. It's not even for usability, but in performance. Somehow, our smartphone has stopped connecting to the server. Whatever we do, the program did not want to be authorized via mobile Internet, nor through Wi-Fi. After another couple of days, the application wrote that it is not compatible with the system and needs to be updated. At the same time there was no update on Google Play. I had to contact the manufacturer who shared the actual APK file. As noted in the company, we are talking about a single failure in the transitional test period.
And the application is very "voracious". With launched even in the background Nerohome, the smartphone may not live until the middle of the day. Not surprising, since the program constantly supports communication with the server and updates the data. You have to check all the time, did not forget to unload the application from the phone's memory. It is better immediately in the settings to activate the function of the break of communication when working in the background.
As for the cost, then the arithmetic is as follows. In our case, one OLEDO server passed on a two-room apartment, one portable and three wall panels, five motion / temperature sensors / light, two door opening sensors and seven smart intro relays. Not much, given that one system can support up to thousands of devices. The cost of the kit amounted to about 2700 rubles, and exactly half of this amount falls on Polish sensors.
The system of the smart home from "Nero Electronics" still needs to be developed. It can be seen that it worked very much over her, a huge number of little things were thought out, with a scope approached design. On the other hand, much remains to be done, first of all at the program level.
The price, in our opinion, can scare some potential buyers. Therefore, it is desirable to spend time to carefully consider the entire functionality of the smart home, all scenarios and events. Perhaps it makes sense to search more budget sensors. You look, with optimal location, they will need less than we used.
In movies, a residential premises often demonstrates, which seems to live his life. Light bulbs light up on hand to hand, curtains open, after a certain word playing music. All this equipment is an intellectual home system, and we suggest to consider how to make a smart home with your own hands, what is needed for this, as well as the scheme of such a system.
A smart home is home automatics, which is a residential extension of building automation. The main automation may include centralized lighting control, HVC (heating, ventilation and air conditioning), household appliances, open the castles of the gate, doors, GSM and other systems to ensure improved convenience, comfort, energy efficiency and safety. It should be noted that for some categories of the population (the elderly, disabled), this event can be necessary.

The intellectual system can be made with your own hands, the most budget option is to set the lighting control in the house or turn on the computer.
Photo - Options for managing smart home To make a lamp that will be "herself" to light up, it will be needed to connect special equipment to it. There are several solutions options. These are tasks:
The easiest way to work with the sensor. Its selling is carried out in any online store, you can buy a channel device, you can develop your own in your parameters. The only remark cannot be installed with such an instrument of incandescent lamp, it may not withstand the load and explode, it is better to work with LED.
Photo - Clear House Concept Another "smart" silent version is a dimmer. Here you will need to touch the lamp, depending on the number of touches, the speaking device will change the brightness. It is very convenient to use on the lamp in the bedroom, nursery.
To adjust control and temperature control, we will need a multichannel system. The central temperature and humidity control circuit consists of:
The most modern way is to buy all components of a smart home, wires, thermostats. After installing devices in each room, the thermostat for the radiator and one on the boiler. You will also need a managed block, or "brain" of the entire system. It is recommended to mount on the heating inlet pipe.
Photo - Smart House System The most simply installation of a video surveillance system and alarm system. Principal safety of security systems:
Smart home is very convenient way It is easier to make your life, often a whole system is purchased completely (Arduino, Knx, Linux).
The cost of each system is individual. The most popular brands are as follows: Beckhoff, Gira, LPT, Redeye, Smart Switch Iot Screen, Teleco. We recommend, before building such a housing, consult with experts, they will help calculate the level of load, calculate power consumed.
