Pass-through touch-sensitive light switches with wi-fi. Smart WiFi light switch. WEB server programming

23.10.2020

Technological progress has brought new, more advanced ways to control light. The old-style switches have been replaced by wireless technologies. The most modern way of transmitting signals is via Wi-Fi. The technology involves transmitting digital data over radio channels. A Wi-Fi switch is used to transmit commands.

Advantages and disadvantages

Wi-Fi devices are characterized by the following positive qualities:

There is no need to lay a dedicated branch of electrical wires.
Lighting devices can be controlled centrally - from one command center. Smartphones, computers, tablets or remote controls are used as a control device. For smartphones and others electronic devices special software, which can be downloaded on the Internet or installed from an installation disk.
Extensive coverage area. Digital radio signals even penetrate walls.
System security. In the event of damage to the structure, a person is not at risk of severe electric shock. The current strength is too low to cause harm to the human body.

Types of devices and manufacturers

The range of Wi-Fi light switches is not very diverse. However, products are classified according to a number of criteria:

The switch is controlled by mechanical or electronic keys. In the latter case we are talking about a touch monitor. The keys are located on the remote control.
Switches are available with or without dimmers. This device allows you to adjust the brightness of the light by changing its intensity. Settings are made by holding or scrolling the corresponding button.
The switch can provide control of one, two or three groups of lighting fixtures. Prices for equipment capable of controlling groups of devices are disproportionately high.

There are several dominant manufacturers of wireless lighting control technology on the market:

Legrand (France). The company's assortment includes, in particular, a line of products called Celian.
Vitrum (Italy). The Italian company uses Z-Wave technology, which allows automating light control processes in a smart home.
Delumo. Products from a Russian company that produces switches, dimmers and thermostats.
Noolite. Switches made in Belarus.
Livolo (China). The Chinese company produces specialized devices for automation, including for the “smart home”. The range includes products for single and double frames for switches.
Broadlink. The company from China produces a wide range of lighting control products.
Kopou. Another company from China offers a dimmer in the form of a key fob.

Connection diagram

Smart light switches are easy to install. If desired, you can install them yourself. You just need to strictly adhere to the instructions. Installation will take literally a few minutes.

The installation process includes two stages:

Installation of the signal receiver.
Installation of the control button (that is, the switch itself).

The receiver has two to four wires. To determine which wire is the input, you should read the instructions. The other wires are outputs (a double switch will have a pair of these wires). Installation involves breaking the phase that supplies power to the lighting fixture. Next comes the connection to the electrical circuit.

If there is more than one lighting group, the actions will be as follows:

We supply neutral wires to the lighting.
We branch the phase on Wi-Fi.
We direct the phase separately to each group of lamps.

The switch is installed in a series of sequential operations. First, drill a hole in the wall. Next, install the plastic socket box into the recess. The installation process here is no different from installing a conventional light switch. The only significant difference is that there is no need for electrical wiring. It is enough to secure the button in the box.

Good day, dear reader.

A little lyrics at the beginning. The idea of a “smart” light switch is not new at all and, probably, this is the first thing that comes to mind for those who have begun to get acquainted with the Arduino platform and IoT elements. And I am no exception to this. Having experimented with circuit elements, motors and LEDs, I want to make something more practical, which is in demand in everyday life and, most importantly, will be convenient to use, and will not remain a victim of experimentation for the sake of comfort.

In this article I will tell you how I made a switch that will work like a regular switch (that is, one that is usually mounted on the wall) and at the same time allows you to control it via WiFi (or via the Internet, as is done in this case).

So, let's make a list of what you will need to implement your plan. I’ll say right away that I intended not to spend a lot on components and chose the components based on reviews on the forums and the price-to-quality ratio. Therefore, some components may seem inappropriate here for experienced electrical enthusiasts, but please do not judge too harshly, because I'm just a beginner in electromechanics and would really appreciate comments from more experienced people.

I also needed: a server with which the switch will be controlled via the Internet, an Arduino Uno with which I programmed the ESP, a router and Consumables like wires, terminals, etc., all this can vary depending on tastes and will not affect the final result.

Prices are taken from Ebay, where I bought them.

And here is what the elements from the table look like:

Now you can create a connection diagram:

As you probably noticed, the scheme is very simple. Everything is assembled easily, quickly and without soldering. A kind of working prototype that you don’t need to tinker with for a long time. Everything is connected with wires and terminals. The only negative is that the relay did not fit into the switch socket. Yes, initially I planned to push it all into the wall behind the switch to make it look aesthetically pleasing. But to my regret, there was not enough space in the socket and the relay simply did not fit either lengthwise or across:

Therefore, I temporarily moved the relay behind the socket until I found a suitable switch box with an outlet to hide the iron inside. But there is nothing more permanent than temporary, isn’t it? So it all looks like this now:

Electrical tape will save you from electric shock... I hope.

Now let's talk about the software part.

And before we start analyzing the code and details, I will give a general scheme for implementing control of a light bulb.

I hope that someday I will rewrite everything and the connection will be based on a faster protocol than HTTP, but for a start it will do. Remotely, the light bulb changes its state in approximately 1-1.5 seconds, and from the switch instantly, as befits a decent switch.

Programming ESP8266-01

The easiest way to do this is with using Arduino. You can download the necessary libraries for the Arduino IDE from GitHub. All instructions for installation and configuration are there.

Next we need to connect the ESP to the computer, for this you will need either a USB to Serial Adapter (such as FTDi , CH340 , FT232RL) or any Arduino platform (I had an Arduino Uno) with RX and TX outputs.

It's worth noting that the ESP8266-01 is powered by 3.3 Volts, which means you should never connect it to an Arduino, which is (often) powered by 5 Volts, otherwise it will burn to hell. You can use a voltage reducer, which is shown in the table above.

The connection diagram is simple: we connect TX, RX and GND of the ESP to RX, TX and GND of the adapter/Arduino, respectively. After this, the connection itself is ready for use. The microcontroller can be programmed using the Arduino IDE.

A couple of nuances when using Arduino Uno:

The Uno has a 3.3V output, but it wasn't enough. When you connect ESP to it, everything seems to work, the indicators are on, but the connection with COM port gets lost. So I used a different 3.3V power supply for the ESP.
In addition, UNO did not have any problems communicating with ESP, given that UNO was powered by 5V, and ESP by 3V.

After several experiments with the ESP8266-01, it turned out that the ESP is sensitive to the voltages connected to GPIO0 and GPIO2. At the moment of start, they should under no circumstances be grounded if you intend to start it in normal mode. More details about starting a microcontroller. I didn’t know this and I had to slightly change the scheme, because... in the ESP-01 version only these 2 pins are present and in my circuit both are used.

And here is the program for ESP itself:

Show code

#include #include #include #include #include extern "C" ( // this part is required to access the function initVariant #include "user_interface.h" ) const char* ssid = "WIFISSID"; // WiFi name const char* password = "***************"; // WiFi password const String self_token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"; // token for minimal communication security const String serv_token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"; // token for minimal communication security const String name = "IOT_lamp"; // switch name, read light bulbs const String serverIP = "192.168.1.111"; // internal IP WEB servers bool lamp_on = false; bool can_toggle = false; int button_state; ESP8266WebServer server(80); // web server HTTPClient http; // web client const int lamp = 2; // Control the relay via GPIO2 const int button = 0; // "Catch" the switch via GPIO0 // function for ping the light bulb void handleRoot() ( server.send(200, "text/plain", "Hello!

if (button_state == HIGH && can_toggle) ( toggleLamp(); can_toggle = false; delay(500); ) else if(button_state == LOW)( can_toggle = true; ) )

A couple of notes on the code: It is very important to declare the GPIO0 pin as pinMode(button, INPUT_PULLUP
When catching the state of a button, it is advisable to set a delay when reading it to avoid false positives at the moment of pressing.

WEB server programming

Here you can give free rein to your imagination and use any available means to create a service that will process requests sent by the switch and send requests to turn it on/off.

I used Yii for this purpose. I chose this framework for several reasons, I needed authorization (since the portal is available on the Internet) and role management (for future experiments), and I just like it. And now my management portal looks like this:

To control a light bulb within the reach of the network, the server itself on the ESP would be enough. But you want to have logs, logic and other devices in the future, so it’s better to use a separate server for control.

This is all about the portal, I think there is no point in writing more about it, but if you have any questions, I will be happy to answer them in the comments.

Instead of a conclusion

Thank you if you read the article to the end and perhaps found something useful in it. I will be glad for advice and criticism. In general, it still seems to me that the bottleneck in the circuit is the 5V adapter and I will be glad if you share your experience in solving such problems. As for the ESP8266-01, so far it has not caused me any complaints except for the special use of GPIO pins. It's been working steadily for the second week so far. Good luck with your projects.

In the modern world, the system “ smart House" With its help, you can remotely control many elements and devices of our home. You can also carry out remote control lighting in the room. Such inventions contribute to the comfort of a given room, and are also used where elderly people live and people with disabilities disabilities. This article will discuss how it works and why a Wi-Fi light switch is needed, which is gaining increasing popularity among the population.

Strengths and weaknesses of the device

Wi-fi light switch has the following advantages:

There is no need to lay additional cable.
It is possible to centrally control lighting devices, that is, from one command point. In order to control the wireless light switch, you can use a smartphone, tablet, computer, or remote control. For tablets and other electronic devices, you must install the necessary software. It can be downloaded from the Internet or installed from disk.
Large signal coverage area. Despite the walls, the digital radio signal penetrates into the desired room.
This system is very secure. Even if the structure of the device is damaged, this does not threaten the resident with a strong electric shock, because the Wi-fi switch has a very low current strength.
The device works normally with all types of light bulbs (LED, incandescent, energy-saving).
You can set different combinations, as well as operating modes of lighting fixtures.

If we talk about the disadvantages of light switches, there are only a few. The main ones are that the price is much higher than conventional keyboard models and there is a certain risk of the batteries in the remote control being discharged, or bad signal Wifi.

Design features

The Wi-Fi switch kit includes a receiver and transmitter. The receiver is a control relay. Can be controlled via a smartphone with access to Wi-fi networks, or using the remote control. When the relay receives a certain signal, it closes the electrical circuit. The relay is installed near or inside the lamp. This is possible due to the small dimensions of the device. The reason for installing the device near the lamp is so that it does not fall out of the radius in which the transmitter operates. If the room has spot lighting, the receiver can be placed in a distribution box or behind a suspended ceiling.

The switch or transmitter has a small power generator that is capable of generating electricity when you press a button on the remote control or send a specific command from your smartphone via Wi-fi connection. In turn, the pulse is processed into a radio signal, which enters the device. Such radio-controlled light switches are quite expensive, and their analogue is control from a remote control that contains batteries.

Types of switches and the best manufacturers

On given time The range of Wi-Fi light switches is not too large. However, products are classified according to several criteria:

The device can be adjusted with electronic or mechanical keys. In the first case we are talking about touch display devices. The keys are on the remote control (remote control).
There are also light switches with both and regular keypads. Using the first devices, you can adjust the brightness of the lighting, thereby changing its intensity. To adjust the brightness, either hold or scroll the corresponding button.
This switch can provide full control not only one, but also two or three groups of lighting devices. However, the price for a wireless device that can control entire groups is quite high.

On this moment There are seven main manufacturers of wireless electrical accessories for lighting control:

Legrand - country of origin: France. The company has a whole line of products called Celian.
Vitrum is a country of origin: Italy. This company uses a technology called Z-Wave. It allows you to fully automate the control of lighting in the house.
Delumo - products are manufactured by a Russian company, which in particular produces dimmers, switches and thermostats.
Noolite – accessories are made by Belarusian manufacturers.
Livolo is manufactured in China. This company produces specialized devices for automation. The product line also includes products for both single and double frames for switches.
Broadlink (China). This manufacturer has a fairly large selection of products for lighting control.
Kopou is the latest company that is also based in China. The manufacturer produces dimmers in the form of various key fobs.

The video below provides an overview of another interesting model of Wi-fi light switch:

Correct connection

In order to properly mount the switch, you need to know its operating principle, what the device consists of, and how to connect the Wi-fi switch. Connection diagram for this wireless device very simple.

One of benefits of Wi-fi The advantage of a light switch is its ease of use and connection. If you really want to, you can install the device yourself. It is important to strictly follow the instructions provided by the manufacturer. This installation takes only a few minutes.

The connection process consists of only two stages:

Installing a radio receiver.
Installation of a light switch (control button).

Basically, receivers have from two to four wires. They come out of the device body. To determine the input wire, you must read the instructions. The remaining wires will be output, for example, a double switch will have two outputs. To install the receiver, you must open the phase that supplies power to the lighting device and connect it to the circuit, while observing the sequence.

In the case where it is necessary to connect more than one lighting group, proceed as follows:

zero is supplied to all lighting fixtures;
the phase is branched in the Wi-fi switch;
the phase should be supplied separately to each group of lamps.

The control button is installed quite simply; first you need to make a hole in the wall using a hammer drill with a concrete cutter. A regular plastic socket box is inserted into the finished hole, and plaster can be used to secure it. The installation process is absolutely no different from the keyboard type. The only difference is that there is no need to lay wires, you just need to securely fasten the button in the socket.

A smart switch is indispensable for people with disabilities, including the elderly. It will also be useful for those who often remember that the lights are not turned off on the way out of the house.

The principle of operation of a switch controlled by a smartphone

The device consists of two blocks - a receiver and a transmitter. The receiver function is performed by a controller (switch) equipped with a Wi-Fi adapter. Based on a radio signal, it closes or opens the contacts of power wires.

The role of the transmitter can be performed by:

Wi-Fi light switch placed on the wall;
special keychain;
router (it receives signals via the Internet).

Advantages of a wireless switch:

no need for cable laying;
control all lighting fixtures from one computer or phone;
automatic switching on/off of lighting in set time according to a given program;
availability of feedback.

The touch switch is easy to use, and in the event of mechanical damage to the housing, it is completely safe for humans. Due to the absence of power cables connected to it, electric shock is excluded.

The range of the device is from 30 to 160 meters. This indicator depends on the thickness of the walls. The equipment works reliably with all types of lamps: incandescent, LED, energy-saving.

Order modern “smart” Wi-Fi light switches and make your home more comfortable.

From the article you will learn why a wireless switch is needed, scope and types, device and principle of operation, advantages and disadvantages, selection criteria, how to connect it yourself, diagrams.

Wireless network switches radically change the idea of controlling lighting devices, simplify our lives and make it more comfortable.

Until recently, such technologies were unavailable due to high prices and limited production.

On modern stage There is a tendency towards their cheaper prices. That is why radio switches and their other analogues are increasingly perceived as an alternative to classic switches.

What is a wireless switch for?

Remote systems that provide control of certain devices at a distance are becoming increasingly widespread. The wireless wall switch is no exception.

It was created to increase comfort, and for senior citizens and people with disabilities it is absolutely necessary.

Using such a device, you can easily control the lighting in your home, change the brightness, turn lamps on and off.

In addition, thanks to the special design, there is no need to damage the walls or make large holes for installation.

Scope of application

Traditional switches are gradually becoming a thing of the past due to inconvenience of use, complexity of connection and installation, as well as a small resource. Wireless analogues have better qualities.

They are stylish in appearance and install within minutes.

The use of such products is relevant in the following cases:

When moving an old switch, when pieces of furniture interfere with its installation. The new device can be mounted anywhere in the room - on a wall, mirror, cabinet or other element of the room.
To eliminate electrical errors. When installing wiring, mistakes are often made that affect the comfort of living in an apartment or house. In such cases, it is not necessary to make a strobe or plan expensive repairs - you can install a wireless switch (with or without a remote control).
When there is a shortage of space. The classic option is that it is difficult to install the switch on a cabinet or other piece of furniture due to the complexity of the mounting. Wireless analogues are overhead, and their installation is accessible even to beginners. In addition, during the installation process there is no need to lay the cable and worry about its disguise. And the radio switch can be placed anywhere, be it a coffee table, bar counter, bedside table or other piece of furniture.
In wooden houses. The advantage of buildings made using wooden materials is undeniable. They are distinguished by their durability, ability to retain heat, and also low price. But problems arise associated with increased security requirements. The best option- installation of open wiring, but it spoils appearance interior and is subject to mechanical damage (including from rodents). Making hidden wiring in a wooden house is quite a problem. The best solution is the installation of wireless light switches, which simplify the process of installing hidden wiring and save money.
To control lighting from multiple locations. There are situations when turning on the light needs to be done from 2-3 parts of the room. To avoid running wires to each switch, it is better to use wireless devices. With their help, lighting control is simplified and the time required for installation work. If desired, you can install wireless switches with a remote control.
If necessary, install additional switches. It happens that after completion of repair work the selected location is not satisfactory and installation is required additional device to control the light. Installing a wireless switch solves the problem.
To turn lights on/off over long distances. What to do in a situation where you need to turn the lamp on and off from another room or even from the street? Pulling a wire to install an additional switch is expensive and unsafe, and the possibilities new technology allow you to avoid such problems. The peculiarity of radio switches is their large operating range - up to 350 m (depending on the model). Control can be done using a simple remote control, which for convenience is made in the form of a key fob.
In order to preserve the design of the room. If installing a switch in a recess is not possible, you have to install overhead types of products that spoil the appearance of the room and do not look very solid. The solution to the problem is to install a wireless device that is thin and fits perfectly into the interior.
As an alternative to conventional devices. During the next renovation of an apartment or house, I want to introduce some innovations into the design and make life more comfortable. One way is to install a wireless remote switch. Such products will cost more, but they are easy to install, have a solid appearance and provide ease of lighting control.

Varieties

Wireless switches are not very diverse, but there is still a certain selection.

They are classified according to three main characteristics:

By type of control;
If possible, regulate the level of illumination;
By the number of lighting devices they control.

Taking into account the above classification, we can distinguish the following types wireless switches:

Design and principle of operation of the main elements of the device

The wireless switch consists of the following elements:

Electrical wiring is only required for the light fixture and power supply to the product receiver. As noted above, the signal is transmitted using an infrared pulse or radio waves.

The second control option is more preferable, because control is possible at a great distance and even from another room.

The installation of the product is carried out according to a simple scheme, for the implementation of which you do not need to have deep knowledge in the field of electrical engineering.

The old switch can be left as additional source on/off when the battery in the control panel is low.

Light control is carried out in the following ways:

By touching a special touch panel;
By pressing a mechanical button;
By sending a signal from the remote control or phone.

When remotely controlled by a remote control, the signal is supplied at radio frequencies, which eliminates interference and increases the reliability of the device.

Walls, furniture and other interior elements will not interfere with the passage of the command to turn on or turn off the light source.

Using the remote control, you can simultaneously control a group of wireless switches (up to 8 pieces). Thanks to this, you don’t have to walk around your apartment or house to turn off the light somewhere in the toilet or bathroom.

The range of the remote control depends on many factors - the model of the product, the design features of the building, the materials used in the manufacture of partitions.

Most often, the signal is transmitted over a distance of twenty to twenty-five meters. The transmitter is powered by batteries.

The disadvantage of the control panel is that it is constantly lost and the lighting has to be controlled manually.

That is why wireless touch switches that respond to normal touch and are used in Smart Home systems are becoming increasingly popular.

Some radio switches are capable of not only turning the lamp on and off, but also adjusting the light level. In this case, the scheme is supplemented with one more element -.

The regulation process is carried out using a wireless switch. To change the light level, press and hold your finger on a button or key.

Advantages and disadvantages of wireless switches

Despite their ease of use, wireless load switches (in our case, lighting) have not only advantages, but also disadvantages. But more about everything.

Ease of installation. For installation and connection, you do not need to drill into walls or lay a separate “branch” of electrical wiring.
Possibility to control several light sources at once from the remote control or via a smartphone.
Large range of action. The control signal in an open area can reach the receiver at a distance of up to 30 meters. In this case, walls or pieces of furniture are not an obstacle.
Safety for adults and children. Even accidental damage to the structure does not pose a health risk. The operating current in wireless remote switches is minimal and not hazardous to health.

The cost of such products is higher than classic “wired” switches. Adherents of economy and conservatives prefer familiar products.
Inability to control due to low battery in the remote control or inability to control due to weak Wi-Fi connection.

Features and principle of operation of the remote light switch

Let's look in more detail at wireless system management. It includes a set of equipment that is used to control the level of illumination in an apartment or house.

For control, not a standard switch is used, but a special remote control or telephone (this was partially mentioned above).

The control panel (depending on the model) can be designed for a different number of channels. It can affect one or a whole group of lamps (up to several dozen).

In the most advanced systems, switching is done using a motion sensor, which sends a signal to turn on the light if a person approaches the controlled area.

If you configure the motion sensor correctly, it will only respond to a person.

The remote switch is based on a radio transmitter. It is he who transmits the on/off signal to the lighting devices.

The range, as noted above, in most devices is up to 30 meters. But on sale you can find models capable of transmitting a signal over a distance of up to 300 meters.

The radio transmitter receives a signal from the remote control and then transmits it to light sources. The remote control usually has two channels, but there are also eight-channel models.

Control can also be carried out using a switch in which the transmitter is built.

A radar is often included with a wireless remote device. It is used to connect the remote control and sockets. With its help, control can be done via a mobile phone. Such devices are called GSM switches.

Management can be done in one of the following ways:

Characteristics that you should pay attention to when choosing

When purchasing a wireless remote switch, you should pay attention to the following parameters:

The type of light bulbs the device controls;
Material, color and appearance of the case;
Operating voltage;
Number of channels;
Radius of action;
Dimensions;
Rated current;
Equipment.

It is also worth paying attention to the following criteria:

Operating frequency range;
Signal transmission method;
Availability of encoding;
Transmitter power type;
Estimated battery replacement time;
Fastening method;
Operating temperature range;
Price.

How to connect a wireless remote switch with your own hands

Let's look at the procedure for connecting a wireless switch using the Zamel RZB-04 as an example.

The model is supplied with the following items:

2-channel radio receiver of small size (type ROP-02);
2-channel 4-mode radio switch (type RNK-04);
Fastening for installing the product (dowels with self-tapping screws, as well as foamed double-sided tape).

The receiver can operate in five different modes:

Inclusion. When the key is turned on, one or more lamps are ignited. You can set the activation to any of the key positions.
Shutdown. The principle is similar to that discussed above. The difference is that when you press the key, the light turns off.
Monostable. In this mode, the light will only be on while the button is pressed. After releasing it, the lamp turns off.
Bistable. In this case, each press leads to a change in state - turning on and off occurs cyclically.
Temporary. Here after pressing the key the light will be on certain time. This option is useful when installing a wireless switch in a hallway, bedroom or long hallway. Upon entering, you can turn on the light, walk a certain distance (reach the bed), after which the light will turn off.

To correctly connect the receiver, carefully study the diagram. First, apply voltage (connect phase and neutral). Only a phase wire is laid to the switch, without a neutral, so it is installed in the place where the lamp (chandelier) is installed.

The second option is preferred. Before performing this work, it is recommended to turn off the electrical power supply using the machine and check that there is no voltage.

Now you need to make an unbroken phase, for which the phase is connected to one of the wires going to the chandelier. To ensure maximum reliability, use VAGO terminal blocks.

When performing work, you should have a wiring diagram for the remote switch at hand.

It shows how to connect the device:

A phase wire must be connected to contact “L”. In this case, there is no need to run it through a switch - the product operates in constant mode.
Connect the neutral conductor, which is taken from the junction box, to the “N” terminal.
The phase that goes to a group or one lamp is connected to the “OUT1” contact. Here you will need the 0th conductor, which can be taken from the junction box or receiver (terminal N).
To “OUT2” connect the phase that goes to the second group or one lamp. As in the previous case, zero is taken from the junction box or from the receiver terminal block N.
Connect the pulse switch to “INT1”. The peculiarity is that when pressed, it only sends a short-term signal. After triggering, the operating mode of the 1st group of lamps changes. Thanks to this feature, the ROP-02 receiver can be controlled using a remote control or a stationary pulse switch.
A pulse switch (one or a group) must be connected to “INT2”. After clicking on it, the operating mode of the 2nd group will change. The principle here is the same as described above.

Now you need to combine the remote light switch with the receiving device, connect them to each other and decide on the operating mode. To do this, you first need to supply electricity.

Now select the appropriate operating mode for the switch. Most often, the standard option is suitable - when moving the switch up, it turns on, and down, it turns off.

To program this mode, do the following:

For ease of use, the double-sided tape is divided into four small squares, which are glued around the perimeter of the product; you must first remove the protective layer. All that remains is to place the switch in the chosen location according to the level.

The installation of the wireless remote switch is complete, and you can install a test lamp and then check the functionality of the system.

To do this, switch the key up - the light should come on, and down - it should go out. When the switch is activated, the indicator lights up.

Wireless remote switches Until recently, they were classified as new and inaccessible technologies. With the growth of production and competition, the price decreases, which makes the purchase accessible to everyone.

The main thing is to carefully approach the choice of product, understand the basic parameters and give preference to models from trusted manufacturers.
