Today I installed it. The application and the device work very well together. The device is beautiful and has many functions. It was tested and works perfectly. I will also give it a 5-star rating if I manage to operate it through home assistant.

P.S.: There is actually a problem with the compatibility with home assistant, it is detected but displays incorrect data. However, it works perfectly fine with the recommended application, I have no issues. I can compromise. Also, it is not as bulky in non-recessed installations. It has almost the same width as the old analog thermostat I had.

The product is Chinese up to a point.
I bought it 2 months ago, 10/2021.
For 2 months, it worked fine.
Then it started turning on and off by itself, changing programs on its own, etc.
I reset it and the same thing happened again.
I called the store where I bought it, and they told me to unplug it and connect it to a socket by itself, and if it doesn't work properly, send it for inspection.
We're talking about a radiator thermostat. So basically, I have to go without a radiator in December and wait to see what they'll tell me. The company's response was laughable.
I bought a more expensive one from a well-known brand and it worked perfectly.
We connected this one to a socket by itself as they told me, and it still did the same thing.
If the company was right, there should have been an immediate replacement, I believe.
In short, stay away from this particular brand and the company that imports them.

    This review is about a variation of the product

    It works flawlessly for 8 months. It needs 220 power to work and is single command. I have a gas burner but can also be used with oil if desired. So far, it has not disconnected me once (home internet has stable connection).

    I am very satisfied. It connected easily to the wifi. It works perfectly and you can adjust several things, such as the daily schedule. You can set different temperatures for each day if you want. Of course, you can also adjust the temperature remotely and have it start as soon as it drops lower. You can adjust the sensitivity up to 0.5 degrees. Of course, it also functions as a regular thermostat, manually. Be careful with the wifi though because the instructions say that it does not connect to a 5GHz network. Only to 2.4GHz.

    This review is about a variation of the product

    I have had the thermostat for about 3 months in my house.
    It has disconnected from the internet 3 times, and the temperature has a large deviation from the normal room temperature, despite me trying to fix it.
    The app works whenever it wants to, it does not respond most of the time (especially if you use data).
    It simply works like a regular thermostat.
    I regret buying it, I do not recommend it

    It worked perfectly for 2 years until it suddenly burned out for no reason. I recommend avoiding Hysen thermostats or other similar-looking brands. It will be replaced with Stege and we'll see how that one goes.

    First of all, you should know that it requires an extra box if you don't install it flush on the wall. Even with the box, it is nice and convenient, it doesn't stand out much, a little more than a regular thermostat, you could say.
    I brought an electrician because I don't know about installations, although it's probably not difficult for someone who understands.
    It connects very easily, never disconnects, and works perfectly with the app. Its simple and unnecessary function perfectly serves the purpose for which I bought it. Good sensitivity regarding the temperature aspect. The only thing that bothered me a little is the sensitivity of the screen because it scratches easily and has left marks because I pressed it a little harder. Otherwise, for its price, it is ideal in my opinion!
