The thermostat has been very convenient for me, it really does what it's supposed to do for the 35 euros I bought it for! I can adjust the temperature remotely whenever I want. It requires a little attention in terms of connection, but it worked for me in the way shown in the picture. The temperature it displays (despite some negative feedback I read) is accurate as I have cross-checked it with a thermometer right next to the thermostat. I don't use it with the programs, so for now I have nothing to comment on regarding that aspect. P.S. The use of a box (external or recessed) is necessary, personally I bought one from a local store for around 3-4 € if I'm not mistaken.

Update 22/2/22.
Suddenly, the temperature reading went up to 31-32ºC (while it should normally be around 20) and it doesn't return to normal (it has done this a few times in the past but quickly returned to normal), I don't know what's causing it, but I haven't found a way to fix it. Therefore, the thermostat becomes non-functional.

So I've had it for a week, my friend who is an electrician installed it for me because I don't deal with these things at all, but it's not something amazing! It doesn't need batteries, it's very easy to connect to Wi-Fi, and so far, in the week that I've been using it, it hasn't disconnected once! Also, for Google Assistant lovers, it works perfectly, obeying commands!

Personally, I got it for my shop because I want it to open at a specific time so that I can find it warm. However, I mainly heat the shop with an air conditioner, I only use the gas in the morning to quickly warm up the space! Where I want to end up is that personally, I wouldn't put it in my house for main use because it has a small disadvantage. Firstly, it shows the house temperature and adjusts the temperature by 0.5 degrees, and secondly, when you set it to, for example, 20 degrees, it will turn on when the house temperature shows 19 degrees! An Olympia Electronics thermostat that I had before shows and adjusts by 0.1 degrees!

Of course, in order to find a thermostat with Wi-Fi connection, Google, Alexa, that shows and adjusts in decimals, you have to go for 80 euros and above, also check out Olympia Electronics, which is a Greek product!

Another disadvantage that I noticed is that you can program it from the application, but it has a program for working days, Saturday, and Sunday! You can't set a program for Tuesday and another for Wednesday on working days, this can only be done for Saturday and Sunday, from Monday to Friday it will be the same.

I give it 5 stars because I knew all these things beforehand from various videos I had watched and they were in my knowledge, but as I said, I don't use it for main heating. The thermostat works perfectly fine, it just has 1-2 bugs for me, which all thermostats in its series have! Now, if someone doesn't have such an issue with the difference, of course, they can get it, it's flawless and does what it says.
