The Wi-Fi relay is designed to control electrical appliances via a WiFi connection in your home or corporate network. It can be successfully used in projects of the “Internet of Things” or “Controlled Home” categories. The relay allows you to remotely turn on or off two of your electrical appliances using a free mobile application for Android. And if your Internet provider provides the ability to access your home network from outside (static IP address), then you have the opportunity to control electrical appliances via the Internet. You can embed the control of our WiFi relay into your own applications and programs, since the command system is open and easy to use.

- Good afternoon. I need to control the temperature in my dacha remotely (via the Internet) - just in case of a heating failure in winter time. You don’t need to control anything (just be able to look at the reading of one thermometer, i.e. I don’t want to overpay for the possibility of remote control, because if the heating turns off, I’ll still have to go there). The method of control is not important (it can be on a smartphone, or on a PC, or even via SMS a couple of times a day). Can you recommend some inexpensive device of yours (or maybe not yours) for this purpose?
The Wi-Fi relay is designed to control electrical appliances via a home or corporate WiFi network and can be used in projects collectively called the Internet of Things. The heart of the WiFi relay is the most popular WiFi chip today, ESP8266. The relay allows you to remotely turn on or off two devices connected to the output contacts of two relays independent of each other. If your Internet provider provides the ability to access the network from the outside, then you have the opportunity to manage your devices from anywhere there is Internet access. Thanks to wireless communication The module makes it easier to place it near the devices that need to be controlled. No gasket is required for the module to operate Ethernet cable. You can control the module using free programs for Android devices. One of them is attached. In addition, the system is available simple commands modules with which you can embed relay control into your own applications.
The heart of this device is the most popular this moment ESP8266 chip.
Why is the ESP8266 chip or, as it is called, “people's wi-fi” so interesting? In the photo you can see it, it is blue. The fact is that the ESP8266 is one of the most highly integrated and inexpensive solutions for working with Wi-Fi and can easily be used as the “brain” of a future product. There are two main applications in ready-made devices: providing Wi-Fi connection and organizing the logic for controlling home appliances using the free resources of the built-in microcontroller.
“Master KIT” released a module under the number “MP3500” on a universal, actually “debug” board. It has a power supply with a wide input voltage range, although, in the case of a relay, the board must be connected strictly to a 12 Volt source. There is a connector for connecting an external microcontroller, for example, an Arduino-compatible one. The same connector can be used to reprogram the ESP8266 module. To do this, you only need a USB-UART adapter.
Coming soon new Wi-Fi– solutions on the same board.
The MP3500 will be a pleasant discovery for those who love using Android gadgets. We have made a demo program for the smartphone with an intuitive interface.
Let's take a closer look at the block itself:

How does the module work?
There are two options for the module to work - this is distribution c own network WI-FI and connecting MP3500 to an existing home network. Together with the device goes clear instructions and a free program WIFI_2RELE.apk for Android, with which you can control each of the two relays installed on the board.
In addition to the presented WIFI_2RELE program, a system of built-in AT commands is also available, knowing which you can access the module control from your own applications, on any platform that supports the TCP/UDP protocol. Using the HERCULES terminal utility from the HWgroup company, which you can find at www.HW-group.com, you can visually study the process of sending commands and receiving a response from the module at the protocol level.
Examples of module AT commands:
SetR0_1 - turn off relay 1
!SetR1_1 - turn on relay 1
!SetR0_2 - turn off relay 2
!SetR1_2 - turn on relay 2
Possible Wi-Fi applications relay:
Implemented the ability to connect 2 electrical appliances through two exits. You can use the relay anywhere at home, the main thing is to comply with technical restrictions on the power of the connected load. After connecting the power supply, the load is controlled through normally closed contacts. When the power is turned off, the relay state is not saved. Master Keith recommends powering the load and module from one phase 220 V and through 1 automatic circuit breaker.
Application options:
1.) Smart Home Projects
2.) Control of lighting, ventilation, blinds, gates
3.) Connecting household appliances, for example a multicooker
4.) Feeding pets
Example solution
Our employee has a rather intrusive cat at home who wakes her up in the morning at about five o’clock to be fed. I think the situation is familiar to many. Previously, a timer was used for the solution. But the problem was that the programmed time did not always coincide with the cat’s desire to eat. After connecting the relay to the feeder and to the lighting in the kitchen, the problem disappeared by itself. Now in the morning, when the cat starts to wake her up, he presses two buttons on the phone - the light in the kitchen comes on and food is poured into the feeder, the cat is fed, and she continues to sleep. And I am immensely grateful to this invention for my vigor in the morning.
By the way, we will also definitely describe the design of the feeder and the technical part in the next publication.
Let's summarize:
1. MP3500 is own development Master Kit on an ESP8266 chip, which consists of two remotely controlled relays.
2. Small sizes, and then I think a “nano-version” will appear
3.Easy to use
4. Attractive price of a ready-made solution
5. Suitable for different needs
With the advent of such a module, even home developers of various Arduino smart home solutions have the opportunity to connect their devices to a Wi-Fi network without any hassles with programming at the microcontroller level.
Hello, dear readers and guests of the Electrician's Notes website.
In my previous publications, I introduced you to touchscreens, controlled both manually and from the control panel.
But today I would like to draw your attention to the Sonoff relay (switch) Basic version with the ability to control directly from mobile phone through Wi-Fi network or Internet.
The Sonoff Basic relay is a small device (88x38x23 mm), which can be easily placed behind the ceiling space, in a building niche, or in the bowl of a chandelier or lamp.
Its cost at the time of publication of the article is slightly less than 300 rubles. As you understand, this is quite reasonable money, and for such a modern device. I bought it from a well-known trading platform AliExpress (link will be at the end of the article).
The kit included two protective covers with mounting screws, but, unfortunately, there were no instructions.
The Sonoff relay has the following technical characteristics, some of which are displayed directly on its body:
- maximum controlled load current 10 (A)
- supply voltage from 90 (V) to 250 (V)
- wireless standard 802.11 b/g/n
- security protocol WPA-PSK/WPA2-PSK
- operating temperature from 0°С to 40°С
- weight about 50 g
Sonoff Basic relay capabilities:
- load management via Wi-Fi
- Internet load management
- load control by specified timer, both with forward and backward countdown
- load management from multiple mobile phones
These are the capabilities of the Sonoff relay. It can be safely used in systems smart home and for other various needs and requirements.
First, I will tell you how to connect Sonoff, and then we will check all its declared control methods in practice.
So, let's go.
Installation and connection of Sonoff relay
For the Sonoff relay to operate, it requires a supply voltage of 220 (V), which means it can be installed without problems in a place convenient for you, for example, in the bowl of a chandelier or directly under suspended ceiling, as well as directly in the junction box, if there is enough space.
To attach the relay to the surface, it has two mounting holes.
The connection diagram for the Sonoff relay is very simple.
The phase and zero of the 220 (V) supply voltage are connected to the terminals (L) and (N) on the (Input) side, respectively. Naturally, when connecting, do not forget about .
Please note that the connected conductors must have a cross-section of no more than 1.5 sq. mm. But I still tried to connect wires with a cross-section of 2.5 sq. mm. As a result, a rigid (single-wire) wire can still be connected without problems, but a flexible (multi-wire) wire can be inserted into the terminal with great difficulty, so it even had to be slightly flattened and deformed.
For example, I used a power cable of the PVA brand, which just has a cross-section of 2.5 sq. mm. At the other end of the cable there is a plug, which I will later connect to any socket with a voltage of 220 (V).
The load phase and zero are connected to terminals (L) and (N) on the (Output) side, respectively.
To make it easier to connect the load, I connected a socket to the relay output.
By the way, terminal covers not only have a protective function, but also act as clamps for power wires or cables.
This is how everything turns out beautifully and neatly. Sonoff relay connected.
As a load I connected LED lamp, about in one of his articles.
Here is a simple example of a Sonoff relay wiring diagram for a group of lamps.
By the way, it is not necessary to use only a lamp or a group of lamps as a load. You can safely connect any other load to the output terminals, not exceeding the rated current of 10 (A). And if you still need to control a load with a current value above 10 (A), then you can connect it to a contactor, and use a relay to control the coil of this contactor.
In this regard, we can add that when using a contactor, you can control at least a single-phase load, at least three-phase, at least alternating current, even direct current.
It will look something like this.
Thus, the scope of application of Sonoff relays is very wide and varied. It can control at least one light bulb, a powerful single-phase electric heater, a three-phase electric motor, etc. It all depends on your needs and requirements.
Now let’s look at all the possibilities for controlling the Sonoff relay in more detail.
I will not open the relay and look at its structure; there is already plenty of information on this matter on the Internet - look at the relevant resources on electronics. And judging by the reviews, the performance of the relay is quite decent. By the way, for those interested in knowing, the relay is assembled on the basis of the famous Chinese microcontroller ESP8266.
Load management via phone via Wi-Fi network
Before I talk about controlling the relay via Wi-Fi, I will say that it can also be controlled manually. To do this, there is a small recessed black button on its body. So, when you press it briefly, the relay turns on, and when you press it again, it turns off. Moreover, for this it is not necessary that the relay be connected to a Wi-Fi network - control will also be carried out in Offline mode.
But besides this, the button also contains other functionality, which I will discuss below.
To implement the ability to control load via Wi-Fi and the Internet, you must install it on your phone mobile app eWeLink. This application can be found for both Android and iOS devices. To make it easier to find the application, you can use the necessary QR codes on the packaging.
For devices with Android application eWeLink can be downloaded for free from Google Play and without special problems install it on your phone. The program interface supports Russian.
For devices with iOS given the application is available in App Store. Download and install this application I haven’t tried it on an iPhone or iPad, so anyone who has tried this application on iOS devices, please post your results in the comments.
After installing the eWeLink application, you will need to immediately register by indicating your country and your email address. In this case, the phone must be connected to the Internet.
After this, a verification code will be sent to your email (valid for 30 minutes), which must be entered in the appropriate “Email code” line. On the same page you must enter a password to log into your future account (at least 8 characters).
By the way, letters reach the mail services Mail.ru and Mail.yandex.ru (Yandex mail) without problems. But as far as I know, Post service Gmail.ru (Google mail) letters with a verification code are not always received, so please take this into account.
Then you need to pair the relay and router by long-pressing (for 5 seconds) the same button on the switch body, after which the green LED on the relay will blink. Check the box for the first connection mode and click “Next”.
Now you need to select our Wi-Fi network from the list and enter its password. To avoid having to enter a password every time, you can check the “Remember password” checkbox. Click “Next”, after which the search for our device and its registration will begin (it took me no more than 2-3 minutes).
After successful pairing, the relay automatically transmits data to the Chinese cloud (Amazon AWS or Coolkit), which makes it possible to control it via the Internet. But I will return to this a little later.
As you can see, our relay is now displayed in the list of all devices (for now it is the only one in the list, but others will appear in the very near future).
When the relay is online, the green LED on its body is always lit. As soon as the LED starts blinking, it means the connection with the router or the Internet is lost. It is precisely by this indicator that it is convenient to determine whether the relay is online (Online) or not (Offline).
While I was testing this device, I didn’t notice any problems with network loss. The device is always online and responds stably to control commands.
Now you can try to turn on the relay via your phone. To do this, click on “Relay 1”. A red message immediately appeared indicating that it is necessary to update the eWeLink application, although Google Play update not displayed.
We go to the device settings (three dots in the right corner) and see that the application has current version 1.5.2, and more is available a new version 1.5.5. Click on the “Download” icon and the application update begins. After the update, the red inscription disappears, and in the settings we can see a new one current version 1.5.5.
Remember!!! The main condition for the relay to work is the availability of Internet access.
If Internet access suddenly disappears, the green LED on the relay body will start blinking, and the application will display Offline mode on its tab, i.e. not available for management.
So, to turn on our “Relay 1”, you need to enter it and click on the round virtual button in the center of the screen. Moreover, you can control the relay from the general list of all devices by clicking on the corresponding small button (on the left). In general, whatever you like.
When the relay is off, the button has White color with fill around it gray background. When the relay is turned on, the button changes its color to green, and the background around it becomes blue.
In addition to the banal principles of control, you can set the time for turning the relay on or off using a timer by setting the appropriate date and time for its control.
Moreover, what was surprising was that the relay operates according to a given timer even when it is offline, which means everything preset programs timers are stored directly in the relay memory.
Click on the “Add timer” button and go to the timers settings page. Each timer is configured to either turn the relay on or turn it off. There are two options for setting the timer:
- one-time (one-time triggering on a given date and time)
- repeated (periodic triggering on a given date and time, including indicating specific days of the week)
In addition to the countdown timer, there is a countdown timer. Very necessary functionality for certain purposes. It is configured similarly to a direct timer, only with the possibility of a single operation.
In addition to direct and reverse timers, in the “Settings” tab (three dots in the right corner) there is a cyclic timer.
In this tab you can configure various options relay operation cycles. I won’t talk about this in detail, because... Everything here is simple and intuitive.
The total number of configured timers, including the cyclic timer, can be no more than 8. And be careful, because when different timers overlap each other, none of them may work!!!
Also in the settings you can specify in what position the relay will remain if the 220 (V) power supply is suddenly turned off. There are three options here. By checking the appropriate boxes, you can choose that when the 220 (V) power supply reappears, the relay can either turn on, turn off, or remain in its original state.
By the way, this is very convenient function. Just remember about the nuance that, when the 220 (V) power disappears and reappears, for some reason it always turns on, even when it is in the initial state off. Imagine that you are not at home, the voltage in the network “blinked” a little and the controller independently turned on the chandelier. Such an incident will not happen here, because... in this case, everything can be customized to suit your needs.
In addition to the above, all your connected devices in the eWeLink application can be grouped together and combined in various scenarios.
Is it possible to control the relay from several phones at once?
Can! Naturally, in this case, you need to install the eWeLink application on each phone.
There are two options here. The first option is to log into the eWeLink application using the same name and password with different phones and control the relay.
The truth is, if you log into the application on one phone, and then at the same time log into the application using the same username and password, but on another phone, then an error will occur on the first phone and the application will automatically exit. In this case, the second phone remains in the application and can be used to control devices.
At the same time, I would like to note that when controlling a relay from one phone, its status is displayed almost instantly on all phones that are connected to it.
Load management via the Internet
In addition to controlling the relay via your phone via a Wi-Fi network, it can also be controlled via the Internet from anywhere in your location, i.e. absolutely from anywhere in the world where there is Internet access.
So, to control the switch via the Internet, you need to log into the same eWeLink application using your name and password that you specified during registration. And then everything is by analogy. It’s the same application, the same settings, the same control buttons, etc., the only difference is that you are not at home within the coverage area of your Wi-Fi network, but at a distance of hundreds and thousands of kilometers from home.
A little about the cloud.
But still, you will not be able to control the relay without the Internet, because... control does not go through local network, and via the Internet, i.e. the same Chinese cloud that I mentioned above. And it doesn’t matter whether control is via Wi-Fi or the Internet, control access is always via the cloud, and to access the cloud you need Internet access.
In this regard, various craftsmen have already figured out how to untie this device from the Chinese cloud or make control only through local home network. For those interested, then this information can be found on certain resources.
By the way, if you need a similar device, but with additional function radio control from the remote control, you can order a Sonoff relay of the RF version.
If you want to control the load where there is no Internet network at all, then you can use the Sonoff version G1 relay (GSM/GPRS with SIM card support). This manufacturer also has relays with temperature and humidity sensors Sonoff TN10/TN16 and two-channel (for controlling two independent loads) relays Sonoff Dual.
In general, the manufacturer Sonoff has a lot various devices, I will tell you about some of the most interesting and significant ones on the pages of my website, so subscribe to the newsletter so as not to miss interesting issues.

And by tradition, a video based on the article, where you can more clearly see the configuration and control of the Sonoff relay:
Sonoff World On relay, from the family of devices for wireless control turning household loads on and off the network via Wi-Fi will become a rather useful and convenient element of your home automation system. If you use a smartphone, have Wi-Fi at home, and also want to control power to various network loads directly from your smartphone, even if you are away from home, then these Wi-Fi relays are just for you.
Simply install the Sonoff relay near an outlet or switch (or even instead of an outlet or instead of a switch), and daisy chain your household appliance with a 220 volt network. Then create a connection via the Internet, set up communication with the relay via Wi-Fi, and control your household electrical appliances directly through the application from your smartphone. Let's take a closer look at five Sonoff World On relay models.
Sonoff World On
This is the first relay in the Sonoff line of Wi-Fi relays. It is designed to control the power of any electrical appliances with a power of up to 2.2 kW from the standard household network alternating current 220-240 V. The operating temperature range of the relay itself (a small plastic box in appearance) is from -20°C to +65°C, and the maximum permissible ambient humidity is 95%. The relay is originally intended for indoor use.
The relay can be connected to an outlet or to a switch, it is ideal for controlling the power of a table lamp, refrigerator, or CCTV camera system. The relay is capable of operating on a schedule with support for up to 8 timers.
All setup and management are carried out through the proprietary Ewelink application in Russian, which is available for both IOS and Android. You can always view the status of the device in the application (whether it is on or off), and, if desired, remotely turn it on or off from the network. In principle, the number of Sonoff World On devices that can be controlled from one smartphone is not limited.
This is the next one Wi-Fi model relay from the Sonoff World On family. This model equipped with built-in humidity and temperature sensors. Thus, the device not only has the ability to operate on 8 timers, it can also turn your loads on and off when the humidity or temperature reaches certain values preset in the Ewelink application.
The ability to control from a smartphone via the Internet still remains, but it is also complemented by the functions of setting action algorithms regarding temperature and humidity.
The model is ideal for controlling the power supply of a boiler, air conditioner, convector, for controlling the climate in a greenhouse, for maintaining the proper temperature at home (for people, animals, or indoor plants), etc.
Of course, you can monitor the temperature and humidity conditions in real time from your smartphone via the Internet. Technical characteristics regarding the power of the switched load are similar to Sonoff World On.
This Wi-Fi relay model can work in the same way as Sonoff World On, functionality and its characteristics are the same, only in addition main function control the power of electrical appliances via Wi-Fi, here we also add the ability to control it from a remote control at a frequency of 433 MHz (one remote control is included with the relay). A model with a remote control is ideal for installation at a security guard’s post to control gates, barriers at the entrance to the territory of a private house, etc.
The WiFi relay is similar in characteristics to Sonoff World On, but it is designed to simultaneously control two electrical appliances, the maximum power of each of which is 2.2 kW. Devices can operate in parallel, which doubles the capabilities in terms of maximum switching power. For example, these could be two oil heaters of 2 kW each.
With this WiFi relay, you can not only control your devices via the Internet via Wi-Fi from a smartphone with a maximum power of up to 2.2 kW per relay, turn them on and off, not only monitor their status online (device on or off) or quickly install control algorithm using timers (maximum 8), but you can also collect statistics regarding the use of electricity by your appliances.
You will be able to see real-time power and current data in the Ewelink app directly from your smartphone in the form of reports for a specified period. Convenient, isn't it? This relay will help create an economical mode for using certain household electrical appliances and save material resources.
The Ewelink branded application is easily found in the store, downloaded, and installed on a smartphone. You just need to launch the application, then you will need to register in the system using your phone number, enter the confirmation code that will arrive via SMS, after which you can add devices.
The Sonoff relay has a button on its body, which you need to hold until the indicator on the body starts flashing quickly. If it starts blinking, you can find the module, enter its name, and set the parameters of its Wi-Fi network. That's all.
Now it is possible to control the relay via a local Wi-Fi network, and if the owner is far from home, then via the Internet via the cloud. The application always displays which relays are connected and which are not. The on and off relays are visible in the application. The Sonoff World On RF relay pairs seamlessly with 433 MHz interface remote controls.
Whether the relay is turned on/off by a button on it, via a remote control or via a smartphone, its new state is immediately reflected in the application. It is possible to share devices, for example, a husband and wife living in the same apartment can control the same devices from both their smartphones.
