Wi fi socket is on. How does a WiFi socket work. Should you use it at home? How a smart wi fi socket works

WI-FI sockets are part of the "smart home" and every year they are actively installed in modern homes, which is explained by the practicality and comfort that the product creates.

wi fi sockets: modern technologies

Smart plugs are gaining popularity every year. You no longer have to worry about whether the outlet is turned off, the process is controlled from your phone and without going home.

It is enough to launch the application and have an Internet connection. A wi fi device will allow you to connect or disconnect equipment at a distance. There are dozens of models from different manufacturers for the choice of consumers. The choice directly depends on the design and consumer preferences.

Practicality

The socket is designed to control electrical appliances in the house from a distance. The work is carried out by connecting via Wi-fi. The device is practical and will become a housekeeper: it will provide protection against fire, save on energy and provide maximum comfort.

Varieties and characteristics

The principle of operation of the outlet is the same, the only difference between the models is in design. Manufacturers provide overhead and inline models. Even at the planning stage of the house, it is important to decide which outlet will be used.

Invoice

Looks like a single plug adapter. The design assumes the presence of such components: an indicator, a switch button, a wi-fi module, packed in a plastic case.

Some models are equipped with humidity sensors, timer, video camera. Such a model can easily replace existing sockets and does not require additional repair work.

Built-in

Designed for concealed installation, with assembly during renovation work. The task of this option is to replace an ordinary electrical point. The housing made of heat-resistant plastic protects the consumer from the emission of harmful halogens. Due to the heat resistance of 748 degrees, manufacturers guarantee the safety of the device.

How does Wi Fi from an outlet work?

Operation is controlled by a built-in microprocessor. The processor coordinates work with a control device - a gadget with an installed application. There are also more complex modifications with network adapters for 4 connectors on the market, but such options are not suitable for everyone.

Wai Fai from the outlet allows you to perform the following functions:

1. Switch on and off electrical appliances at a distance.
2. Control the amount of electricity used.
3. Reboot electrical appliances.
4. Set a timer to control devices.
5. The presence of a temperature sensor ensures fire safety.

Before connecting the device, you should make sure that its power is lower than the power of the outlet. Such information is provided in the technical data sheet of the equipment.

How a smart wi fi socket works

When the socket is connected to the router, the device receives a unique IP address. The pinned address allows you to communicate with other objects over the Internet. The signal is encrypted to protect the device from unauthorized access. The settings are stored on a server or device. In the first case, statistics and data are saved reliably, but in the second, if the connection is broken, they will need to be restored.

The programs are freely available and installed on the control device - any modern gadget.

With air temperature sensor

A device with a thermal sensor will cost more than other alternatives, but it will keep your home safe. The sensor measures and monitors the ambient temperature. If an excess of the norm is recorded, which can cause a fire or a short circuit. The smart device will instantly disconnect the devices from the power supply and send a message to the owner of the smartphone.

Smart home control

The concept of "smart home" has appeared a long time ago. The owner of such a house controls the equipment using the program installed in the phone. To start using the outlet, you need to create an account in the "cloud", which is recommended by the manufacturer.

If this is not done, then only basic functions will be available to the user - turning on and off electrical appliances. Additional functionality will be available after registration.

After launching the application for smart devices, a gadget is added. Each smart socket is signed with a name and an image is uploaded. This approach makes it easier to navigate your home, especially if there are many such devices.

Some models can be controlled by the popular Amazon Echo and Google Home voice assistants. But commands are given in English. Smart home control allows you to create a schedule and enable the “Away” mode, which allows you to simulate the presence of the owners in the house when they are not really there.

Appliances often track energy consumption, which allows you to make predictions about the cost of this resource. Such a smart device allows you to control other devices, life becomes more comfortable.

Operating rules

The socket works in the range of 100 - 240 V, with an output power indicator from 2 to 4 kW. Such parameters allow connecting devices with large short-term loads. We are talking about heaters or a food processor.

Each manufacturer provides individual instructions for the devices, but the principle of their operation is the same. The only difference is the availability of additional functions.

Install a special application on the gadget and check the Internet connection.

The software is selected by the QR code on the package from the outlet.

The program must be set to search for a device. A special password is entered to connect. Only after that the wi-fi device will be connected to the network and ready to work.

After completing all the settings, connect the device that will work from the outlet. Individual settings for each device are carried out according to the instructions for the device. To ask for settings, press the on / off button for six seconds.

Advantages and disadvantages

A modern device allows you to control the operation of equipment in the house from a distance. The rest of the advantages include:

The disadvantages of a modern device include:

1. When the electricity is cut off, all settings are lost.
2. Some models may not be compatible with the router.
3. The Wi-fi socket reacts to its time zone, which should be taken into account when choosing a manufacturer.
4. In the event of a failure, the device is turned off.
5. Without an Internet connection, it is impossible to control the outlet from a distance.

Wi-Fi controlled socket: service life

Each manufacturer indicates a warranty period. Such models work no less than conventional outlets. If necessary, they can be easily dismantled and new ones installed. Chinese models will work for up to a year, but European manufacturers give a guarantee for three or even more years. In fact, the actual service life of such outlets is much longer. Therefore, it is worth choosing a model a little more expensive, but the quality of materials promises a long service life.

A Wi-fi socket is a part of a smart home, which is designed to provide maximum comfort for residents. The device is a simple example of home automation, which has become more popular in recent years. The task of the outlet is to fulfill three assigned functions - ensuring safety in the house from unauthorized sunburn, ensuring energy savings and increasing comfort conditions.

The devices are presented in two models - overhead and built-in, which are selected taking into account the needs of the consumer. The principle of operation is simple, and installation does not take much time. The money spent will pay off and everyone will be delighted with the work of the Wi-fi socket.

Useful video

Hello dear readers. Today I got a rather interesting device for review, namely the HS-100 smart Wi-Fi socket from the largest manufacturer of network equipment TP-LINK. The manufacturer's assortment includes only two such devices so far - the HS-100 model and the HS-110 model. The second model differs only in the added monitoring of energy consumption, the rest of the functionality is the same. The average retail price, at the time of this writing, is about 2,500 rubles.

As an introduction, a few words about the very concept of "smart home", which has recently been gaining more and more popularity, including in our country. What is it, you ask? In two words - home automation using modern technologies. In Western terminology, two separate concepts are usually distinguished - home automation (smart home, home automation) and automation of a residential building (smart house, building automation), due to the difference in the scale of automation of an individual apartment and a building as a whole. Smart sockets belong to the first area - home automation. Functionally, devices of this type are capable of remotely turning on / off devices connected to them, including without human intervention - according to a schedule. I will try to describe in detail how this is implemented in the TP-Link HS100 model in this review.

Specifications.

Protocol - IEEE 802.11b / g / n Wireless transmission type - 2.4 GHz, 1T1R System requirements - Android 4.1 or higher, iOS 8 or higher

Packaging and equipment.

The device comes in a small white cardboard box. The box itself is covered with a film, which additionally serves as a guarantee of receiving a new product in the store. On the front side there is a photo of the device itself, the name and logo of the manufacturer.

On the right side is a side view of the device, equipment, electrical specification, barcode and model number. There is also a QR code, the link leads to the product page on the manufacturer's website (in English).

On the left side there is a description of the product's features, again in English.

On the back of the box are the system requirements for the mobile application and its key capabilities, as well as manufacturer's data and place of production. All information is in English.

Above there is only the manufacturer's logo and euro hanger. Below is a sticker with a barcode, serial numbers. And the manufacturer's data, this time in Russian :-).

Box "matryoshka", to get to the contents, you need to pull the lower part.

Above is the documentation, underneath is the socket itself in a rigid plastic form.

The documentation includes a warranty card, two quick setup guides (only one of them contains Russian), a book with support service contacts (including for Russia), the text of the GPL license (only in English).

In general, there are no complaints about the packaging, the device is reliably protected from external factors. Somewhat disappointing is the low Russification of packaging and documentation, only the very minimum has been translated.

Appearance.

The body of the socket is oval, made of white polycarbonate. Consists of two halves - a front part with a socket and a back part with a plug. The front surface is glossy and initially covered with a shipping film, in the rest of the parts is matte plastic. The maximum dimensions are 100.3 x 66.3 x 77 mm (58 mm excluding the length of the forks) mm. Front panel dimensions 55 x 80 mm. Socket and plug "Schuko" type, with a pair of grounding contacts in the form of brackets. In our country, they are usually called erroneously "euro". On the back there is a sticker with the model, electrical data, serial number, MAC address.

There are only two buttons on the case. On the front there is an on / off button with an LED indicator of operating modes. And on top is a settings button - for pairing with the app / resetting to factory settings.

The build quality is at the highest level, everything is well fitted, no cracks, backlashes or creaks are observed. Truth and the possibility of disassembling the device is not provided, which may upset someone. But the manufacturer cannot be blamed for this either, this is his guarantee against "naughty" pens.

At work.

To begin with, the general principle of operation of the device, the circuit is taken from the manufacturer's website.

The smart socket, thanks to the built-in Wi-Fi module, connects through the home router with the TP-LINK Cloud cloud service. The Kasa mobile app also connects to the cloud, allowing you to control your device remotely from anywhere in the world.

The setup process itself consists of three simple steps:

1) Install the Kasa mobile app on your smartphone(Android 4.1 or higher, iOS 8 or higher) 2) Create TP-LINK Cloud account. 3) Step by step in the application, follow the process of connecting the smart socket to your home Wi-Fi network.

So, first, install the Kasa for Mobile application on your smartphone. At the first launch, we are asked to log into an existing account, or create a new one.

We choose to create a new account. A confirmation letter is sent to the mailbox specified during registration. Follow the link in the letter and click continue in the Kasa app.

A window for selecting the device type appears. We choose SMART PLUG.

We turn on the socket into the mains, the indicator on it lights up yellow, then. After 15 seconds, the indicator starts flashing yellow / green, then. Within a few seconds, an automatic search takes place, after which a window for assigning a name to the found device appears.

At this point, your smartphone will be connected directly to the wall outlet as an access point. At the same time, on iOS devices, you will need to manually find an access point and connect to it, and then return to the mobile application.

After entering the device name, you can choose an icon - 21 options from the standard ones, or put your own one from the album / camera.

This completes the device connection.

The home page of the application opens with a list of devices.

The settings of the application itself are minimal, in fact, apart from the item for checking the firmware update for the device, there is nothing useful and there.

The main page of the connected device looks like this:

There is an on / off button, an operating time counter for the current day, a line of nearest events and a choice of modes - Shedule, Away and Timer.

In the upper right corner there is a button for the settings of the connected device. In them, you can enable / disable remote control, change the name and icon, change the time zone, view information about the device.

Now I'll tell you more about the modes.

First mode Shedule or work on a schedule. Go to the corresponding icon, click on the plus sign to add an event. We choose the time and action - turn it on or off, there is a repeat mode for certain days. At the end, click save, and the event appears in the list.

The next operating mode is Away Mode or "not at home" mode. In this mode, the device is randomly turned on / off, creating the appearance of presence. The time interval is set here - the beginning and the end, the repeating mode by days is also present.

And the last one is the regime Timer- turning on or off the device after a specified period of time from the current one.

Another small remark on the remote access mode - if you wish, you can disable it in the settings, in this case, control will be open only for devices of the home Wi-Fi network, access from the Internet is blocked.

As you can see, everything is quite simple and intuitive.

A little help on the indication of work:

Flashing yellow and green- setting mode using the application. Fast blinking green- network connection. Lights up green- connected to the network. Fast blinking amber- reset to factory settings. Lights up yellow- reboot (download). Lights up red- no network connection.

It also shows that the outlet is energized - the power icon is green or off. Moreover, the button is mechanical, if desired, you can turn on the voltage supply manually.

Well, in terms of the functionality of the settings button:

- holding it for 5 seconds puts the device into setup mode using the app - holding it for 10 seconds will reset the device to factory settings

As for the application, there are no complaints about stability, no freezes occur. An example of work can be found at the link below.

From the side of the device, everything also works like a clock - the socket was installed at a distance of about 10 meters from the router, through one concrete wall, on the refrigerator behind the microwave. In this case, no breaks in communication were observed.

The only thing that was noticed is that sometimes it does not find the device the first time with a 3G connection, if you go to the page again, the connection is established. Although this is rather a problem of the quality of the mobile Internet.

I was also pleased with the time of entering the "working mode". For an already configured device, this is about 20 seconds:

As a result, the socket "got accustomed" to the farm and now regulates the compressor in the home aquarium, according to the established schedule.

A small addition on the behavior of the device in "emergency" situations:

1) Power outage - everything works correctly. 2) Disable Wi-Fi with subsequent restoration- everything works correctly. 3)Turning off the power / Wi-Fi and then restoring WITHOUT CONNECTING TO THE INTERNET - all timers / schedules are reset, assigned tasks will not work. Only when the Internet connection is restored, all old tasks will appear and the device will work normally.

The reason for this behavior in the third scenario, as I understand it, is the lack of an internal battery to maintain the device's timer, i.e. after a power outage, the device time is reset to January 1, 1970. And only when you connect Wi-Fi with Internet access, the time is synchronized. The same thing happens after the Wi-Fi break and reconnection - if there is no Internet access at the time of connection, the internal timer resets until January 1, 1970. In this case, only the time zone can be specified through the application, there is no possibility of manually setting the date / time.

So it is worth taking this into account in work, without an active Internet connection, "smart" opportunities are significantly reduced. That is to say, the flip side of modern technology.

Conclusion.

It's time to summarize. For me personally, this was the first experience of communicating with such devices. Therefore, the first time I just played with a remote on-off. Blinking a lamp from the other side of town is an exciting experience ...

But seriously, the thing is very useful and will come in handy for many in the household. Anything can happen, sometimes the connected equipment can be in hard-to-reach places, but you need to disconnect / turn it on remotely. In this case, the thing is irreplaceable. The main thing is that Wi-Fi / Internet are available. Well, remember about binding to a mobile application - all control is only through it, there are no web interfaces here.

So whoever really needs it will buy it. Yes, now the prices for such solutions are not that low. Still a novelty for the Russian market. Yes, and the course "wooden" is not happy. But, one can hope that with the appearance of wide competition in this market, the price of such solutions will inevitably drop.

Advantages and disadvantages:

+ assembly, design, operation + ease of setup

The lack of Russification in the Kasa application - there is no built-in non-volatile timer (setting the device time only via the Internet).

May not suit:

- price

Thank you for your attention and happy shopping!

I express my gratitude to the CSN company and the TP-LINK company for the opportunity to test this device.

Control your home comforts no matter the distance

Remote turning on and off household appliances using a smartphone

With an internet connection on your smartphone, you can control your home appliances from wherever you are. And in combination with a Xiaomi router, you have the opportunity to set certain scenarios for using a smart socket. For example, before leaving work, you can remotely start a multicooker using a smartphone, turn on the light in the hallway, an air purifier or a water heater, so that when you return home after a hard day at work, you can immediately plunge into the atmosphere of warmth and comfort.

Safety first

Mobile monitoring of the state of connected equipment
Remote on and off

You no longer have to worry about unplugged electrical appliances when leaving the house. With the “Xiaomi Smart Home” application, you can check the status of the connected device and manage its power supply at any time. This will not only reduce energy consumption and ensure safety, but also increase the level of comfort in your life.

Scientific approach to energy consumption

Schedule Your Home Appliances to Work

The timer function not only reduces energy consumption, which has a positive effect on the environment, but also makes the use of household appliances even more convenient, while extending their lifespan. For example, you can set a timer for the heater that will automatically turn off when you leave for work and turn on half an hour before returning home, ensuring a comfortable temperature when you are at home.

Compact size for simultaneous use
several sockets at once

Thanks to the optimized design and improved organization of the internal components of the socket, its size allows several smart sockets to be simultaneously connected to the surge protector, which makes it possible to remotely control even more household appliances.

Complex manufacturing technologies

The socket housing is made of fire-resistant material that can withstand temperatures up to 750 ° C, and is manufactured using wave soldering technology. The build quality of Xiaomi smart plug is approved by the national CQC quality standard. The socket has a built-in temperature sensor that monitors the operation of high-power devices and controls the internal temperature of the socket, and when the temperature rises significantly, it sends a corresponding notification to the user. When overheated, the outlet will automatically suspend the power supply to prevent fire and damage.

Three easy steps to use

Using the mobile application "Xiaomi Smart Home", you can easily and easily control the Xiaomi smart socket

In the age of information technology, when spacecraft roam the vastness of the galaxy, and bloggers send cameras into space, I finally decided to try on myself a part of the ecosystem under the general name of a smart home. Today I will introduce you to a WiFi socket from itead studio, model Sonoff S26F with a European plug, released this summer.

The main purpose of this socket is remote control of consumers. Management is carried out thanks to the WiFi network to which the device is connected and authorized. To work, however, you need to download an application for a mobile phone, where you can set the necessary scripts, set countdown timers, or "share" the authority to control the outlet among authorized persons. Now you are familiar with the basics of this outlet, everything else is in order. Let's start!

This parcel was delivered by a courier who apparently kicked her all 9000 km while she drove to me. The outlet itself got a little. There is no particularly useful information on the box itself, on the back there is a standard place for a sticker with the device model (the sticker changes depending on the type of plug)






The Sonoff S26F socket itself awaits us inside. The body is made of white glossy fireproof plastic, the socket is of the EU type. For protection, shutters are provided, as well as grounding contacts. The whole outlet is quite lightweight and compact. There is only one control body and that serves to forcibly turn on the device, as well as to authorize the outlet on the network. At night, it does not shine very brightly, but it will attract the eye.


The kit also includes instructions in Chinese and English. It describes in detail how to connect the socket to the standard application and the WiFi network. I spent a lot of time on the first connection until I rolled back to the previous version of the EWelink app.




The maximum power of the socket is 2.2kW / 10A. Therefore, make sure that the load matches the given values. Otherwise, you will have to change the fuse, this is the best case.




To disassemble the socket, unscrew the 3 screws on the back. Next, he removes all the collapsible parts, namely the control board and the socket itself. On the back of the nest, you can see the protection from children in the form of a curtain. If desired, you can remove.




The control board is soldered to the plug with copper stranded wires. No marking, but similar to AWG26. The only information is compliance with the gb5023.3-1997 certificate. A fuse is provided on the board, which can be easily removed if necessary.


The board is clean, no traces of free soldering were found. Voltage regulator - AMS1117 at 3.3V. Required for further operation of the WiFi board. The power supply unit with galvanic isolation from the mains is also visible here. There are even cuts in the board.


The control is based on the Fanhar DC5V - 10A250VAC electromagnetic relay. This relay is rated for 1,000,000 operations.


A separate board soldered directly to the main board is responsible for the wireless connection. The board was manufactured in January 2018, the board is used on all models of S26 sockets. ESP8266 is used as a WiFi microcontroller. This controller serves as a starting point for most household crafts. Here you can also see the contacts for connecting the converter.




Having familiarized ourselves with the inner world, let's move on to management. First, let's figure out how to connect to the EWlink app. First, download it from Google Play or App Story. After starting, you need to add a new device, select the appropriate item and follow the instructions on the screen. Namely, the correspondence of the flashing point (the number of flashes and the period) in the application and on the outlet itself. To put the device into pairing mode, you need to hold down the button for 5 seconds, after which the blinking should become the same, and when you press further, the application will prompt you about the found device. The next step is to connect to an existing WiFi network. After entering the password, you need to give a name to our outlet.


And now the main menu of the application opens in front of us with the ability to select a mode. Also, on the main menu, you can forcibly turn on or turn off the outlet completely, without further switching on according to the schedule.


Let's take a closer look at each mode.
Timer. Allows you to create a program for the outlet.
Countdown. A very convenient way to set the time before turning off the night light, for example.
Cyclic timer. This item has already appeared in the new version of the application, it allows more flexible setting of the timer.


The standard function for Sonoff devices, namely delegating control of the outlet to other users, has not gone anywhere. It is enough to enter the account name and select which functions can be used.


In the settings of the device itself, you can see the response time and who did it. There is also the firmware version and the ability to enable notifications. If you want to rename the device again, this is also done in this menu.


Now a couple of examples of my use. As you can see from the name of the outlet - "Aquarium outlet", a device is used to turn on the backlight in the aquarium. It is enough to set the on / off time and enjoy the automatic operation of the device.

It was also very convenient to use when connecting a night light in the child's room. If your child cannot sleep without a small light source, and you do not want to walk and check, then you can set the countdown until it turns off.

Both scenarios can be executed without smart devices, but then control over what is happening will be necessary.


And now the most interesting thing, answers to questions during further operation.
1. If the socket is connected to the WiFi network only for control, then where are all the timers stored? And they are stored in the outlet itself, but an Internet connection is necessary to synchronize the current time. Therefore, in the absence of the Internet, the socket will work with the current program (if you have a cyclic timer)
2. What happens to the timers when the router is rebooted? They will be saved in the memory of the socket and will be executed strictly according to the schedule. But if a power outage occurs and the router takes longer than usual to load, then the timers will not be loaded. Apparently the outlet has a specific polling timing.
3. Declared support for Google Home and Amazon Alexa, what's the point? Both devices are a switch in the form of an external speaker that can control the outlet when they are in the same WiFi network. It is enough to say "ok, google plug in the aquarium / unplug the aquarium". But with Amazon Alexa, you will have to learn English, since Alyosha does not understand Russian. That is, if there are several “smart devices” in your house, then they can be controlled without opening the application on the phone.

And now a question for filling. Is it possible to untie the socket from the cloud and keep control over it ?! It is possible, but with the transition to third-party firmware. This requires an interface converter, soldering iron, PC and firmware. For those wishing to learn more, I will leave a profile topic on the forum.

What minuses I see for myself. Firstly, there is no way to see the power consumption through the application or something else. It would be useful for testing low power electrical appliances. Second, this is a rather difficult transition to management bypassing the cloud. And thirdly, there is no support for 5GHz WiFi networks, but only 2.4GHz. The rest is quite a suitable device that fully fulfills its functions.

The joy of using the first Sonoff WiFi sockets was short-lived. Of course, it is convenient to turn on and off some device remotely, but in that case there are some inconveniences. Firstly, it is impossible to connect a more or less powerful device, and, secondly, it was impossible to find out, measure, realize how much the device consumes. Finally, I found an outlet that would solve these problems. Well, not straight 100% diamond-brillant, but quite a working option.

The Blitzwolf BW-SHP2 socket comes in such a nice glossy box.


Delivery and other contents of the box, except for the outlet itself, seem to me uninteresting, but if anything, then

Delivery to Moscow took as much as 45 days. The package came in such a creepy black bag


... inside of which there was a foam larva that preserved the insides from the vicissitudes of the postal route


On one side are the characteristics of the device, dimensions (which is unusual) and other information about "certification" and compliance with the highest quality standards. The QR code simply leads to the site




An open box is greeted with a piece of paper with wishes and color instructions




Here you can see that we have a serious 16A device. This means that you can turn on as much as 3.5 kW.

And here is the socket. A kind of swollen adapter.






Despite its compactness, the adjacent socket in the double socket overlaps, and you can't even turn on a thin plug nearby.


The button is illuminated with a uniform blue or red light. Looks very aesthetically pleasing in contrast to the terry lantern on Sonoff sockets




The insides literally glow


Dimensions (edit)


Of course, at first I played with an ordinary light bulb, but before turning on a serious load, I decided to open the device to see how it is in general. At least make sure that the relay is at least not 10A.

First of all, I got into my set of secrets from the Bison, but the necessary triangular bit was not found ((I needed a straight line like a hexagon, but only with three corners)) As a result, I turned it off with an ordinary flat screwdriver the size of one side of the triangle.


The first thing we see on the board is the date of either manufacture or firmware revision, 20180926. By the way, the order was placed on 09/27/2018 (and sent only on 10/29/2018). Marvelous!


We look at the WiFi module. Honestly, despite the abundance of numbers and letters, nothing is clear. Well, and a no brainer that this is ESP. There are no special pins for playing "flashing" on the board, like in Sonoff, but still.


UPD: I did not open the WiFi module, of course, but who did it with a similar outlet, finding there

In this photo you can see a fat frozen drop of flux or some other rubbish. You can also see the melted piece of the latch holding the board. It seems that this is from a soldering iron. Because in subsequent tests, the outlet barely warmed up even at the maximum short-term load and barely warm at a constant load of 2 kW.




I scraped the contacts with a knife. Copper, copper underneath. Rather like this: yellow metal, inside is also yellow. Well, the magnet doesn't work.




This is the BL0937 chip itself, which calculates the power consumption. Datashit at least.


Voltage regulator for 3.3V, obviously for ESP-shki.


The connecting wires are thick - 16 AWG.


Well, the relyukha is all at 16A. ...


And here is the button itself. The button is very pleasant to the touch)


Well, in the end, I connected everything I could: microwave, kettle, refrigerator. If the power is exceeded according to the indications in the application 3600 W, the outlet is turned off. Moreover, the load relay turns off, the outlet itself continues to work and remains online.




Here, before turning on the refrigerator compressor and when it turned on. After the protection is triggered and the load is disconnected, the current readings are immediately reset to zero, the power is displayed for some time and then it is also reset to zero.

In general, the recommended application is not much different from similar ones and only the section of measurements and statistics, which was shown above, deserves attention. The entire application is in English. But fortunately, the outlet works great with a more russified application. Although the most interesting section of measurements is still in English (despite the fact that for this section it is still in Russian). Adding an outlet to the application is similar to Sonoff and others: we plug the device into the outlet, hold down the button for a few seconds and start the connection process in the application, specifying the WiFi network data. I will give screenshots with the connection and operation of the application

application

As I said, the socket is controlled by the ESP module and in the list of home network devices it looks like ESP_F0C738

Only one open port was found


As for the load. At first, a tee with a kettle, microwave and refrigerator hung on the outlet for a month to be supervised, if anything. Now, for a couple of months now, the outlet has been working in my dacha to control the operation of a 2 kW boiler. The socket does not experience any significant heating during prolonged operation (the boiler heats up to operating temperature in about 3 hours). The control is stable, the socket is online all the time and can be switched on from anywhere in the world via the Internet. Not once during this time did I have to pull it out to dump it. By the way, when the electricity is turned off and then turned on, the outlet remembers its on / off state. I really didn't check the safety of the timers, I'll try to check if I don't forget. It is also possible to create all kinds of scenarios or connect to Alexa. There is support for IFTTT (search by SmartLife). But I still don’t use all sorts of scripts and other cleverness. The timer is enough for me, which I turn on upon arrival at the dacha on Friday night, so that the boiler warms up to the morning garbage dump. You can create several timers for switching on and off. In fact, these are not timers, but alarms, tk. perform an action for some time, for example, like my Turn on at seven in the morning (07:00). But there is also a timer, i.e. taking an action after a certain period of time, for example, after an hour. Regarding statistics and consumption readings, I can say that it is not entirely accurate. The outlet readings are slightly different from the readings

P.P.P.S. Checked how the socket works without the Internet. It turned out that the socket can be turned on / off purely via the local network, but the schedule settings, timers and consumption statistics are not available. In this case, the socket remembers its schedule even without the Internet, and the timer works.
