Automation and smart devices are sweeping across the planet. Most likely, it is already difficult to find a modern apartment or house without any automatic system. The most useful and simple automatic devices are sockets. Whether it is just mechanical to electronic timers, or sockets capable of being remotely controlled via various communication channels. GSM socket from Telemetrika is a prominent representative of domestic automatic devices for simple power management. Consider it in more detail.

So, the socket is in a tight box.

')
The box itself is informative and allows you to understand what is inside and what it serves.

The box itself contains: an instruction manual, an automatic socket and a separate module - a temperature sensor.

The sensor is made in an interesting form factor. He has a papa jack jack. By the type of interfaced devices to phones through headphones.

The socket itself has a connector for connecting this sensor, a mini USB, apparently for the ability to fix the firmware or connect to a computer and a button for manually turning the power on and off.

On the other side is the SIM card slot.

In front there is a connector for plug 220V and two status indicators - power and GSM signal.

Behind the information about the device and small TTX.


We insert the SIM card into the slot, and the device into the outlet.

Our smart socket immediately begins to search for a GSM network and register in it, after a successful registration a single squeak occurs. Next, the outlet must be set up by sending an SMS like # 0 # to its number.

This is necessary so that the main control number is added to the device’s memory.
The socket receiving SMS, also gives a sound signal, and at the time of receipt, the network indicator also flashes.
Since the balance of the SIM card was 0, then the response SMS was not sent to the socket, but it registered the number. I learned this after replenishing the balance sent a second command.
The socket answered that the number is already registered.

In general, the instructions have a lot of commands for SMS, but teaching them and typing is not very interesting, I would even say uncomfortable. For these purposes, Telemetrika released an application available in the Play Store and the Apple Store.

It is universal for Telemetry products and is suitable not only for the outlet. In addition, it is also very simple. The application just sends SMS for you. Answers from devices also come to you in the form of SMS, the application does not display them in any way, this is just the “sender” of commands.

When you first start and add a device, the program registers the main number, to which the socket naturally responds that they say I’ve been a long time ago, just damn it.

Further, the application offers to send SMS to check the status.

After these two procedures, the socket appears in the device list.
But despite the fact that the application very simply interacts with the outlet, it has quite good functionality for converting your desires for managing devices into teams.

For example, scheduled control.

Or control by temperature or timer.


You can also simply monitor the temperature; in this mode, the socket will send ambient temperature information from the sensor to the selected time interval.
If you connect a small heater to an outlet, for example, you can warm up a country house for your arrival, or rather a small part of it. Or make these outlets a few.

With heaters you need to be careful. The socket is set to 16A relay, as described below. Just do not overload the outlet, otherwise it will cheerfully inform you that it has become very hot in the house, and then about disconnecting 220V to the mains.

As a matter of fact, I tested the outlet while on a regular light bulb.

Here the socket is on, the lamp is on.

But already off. It's simple.

Why, in the age of ubiquitous WiFi Internet, the socket is made in the form factor GSM?
Everything is simple, this device is designed primarily where there is no this very Internet. The GSM signal is more profitable than the Internet in the form of WiFi and even GPRS. He is able to break into the wilderness, where, for example, is your summer cottage, far from the city, and control your devices.
Comparing it with home-made automated sockets, for example, the well-known Xiaomi or early versions of kankun.


You understand that they look more profitable against the background of GSM sockets and give more functionality. But they have a number of limitations in the form of not always Russified and even anglicised software, non-standard connectors for our types and sometimes binding only to Chinese servers.


In principle, it would be possible to replace such an outlet with a simple timer with a schedule function.

But he has no feedback and does not have a temperature sensor extending functionality.
So, for giving or a country house, where there is no permanent Internet, this is a great option.

With the use of clear, now look inside.

We take out four silicone pins and snap off the front cover. It holds an additional two clips in the center.
A plate was found on the cover, this is how GSM antenna is implemented.

Then you can see the board with the main brains and battery connector. There is a battery that allows you to send SMS when power is lost in the network. The socket works independently for several minutes without external power.

Further, under the main board for an additional plastic shield, there is a separate board that works with the high-voltage part. electronics is divided and right.

Unscrew the two screws and see what's inside.

And here is the relay. For those who understand these types of relays, I propose to express their expert opinion on the maximum power that should be switched to this outlet.
Findings:Pros:
- independence of the Internet
- mobility
- expansion of functionality due to temperature sensor
Minuses:
- you need to have a separate SIM card and monitor the balance
- not the smallest device size
