It works perfectly. The temperature it shows is 2-3 degrees higher than the actual. Other than that, perfect

After a year of use, I will say that it is value for money. The temperature deviation can be corrected with a calibration

I waited 1-2 years to not spend 150 euros that other brands ask for. Fully satisfied with the purchase last winter, value for money. Okay, it has a deviation of 1-2 degrees, but like most, it depends on where you have the thermostat. Average in capabilities but flawless Tuya app.

Installed a month ago with the recommended connection (bridge to 5, etc.). Everything is fine, easy to use. The only strange thing is that when it is in boiler mode (only heating the water of the water heater) while the radiators are cold and the room temperature is constant, it seems to increase the temperature. In winter, when it will be used daily, its reliability will be better understood.

So far it is functioning perfectly, easy connectivity with Wifi and easy installation. I installed it flush with a simple round switch box and it fit perfectly, and it is smaller than it appears in the photos, everything is covered from the back. I connected it in the classic phase-neutral (L-N) configuration and placed the command in the dry contact (5) and bridged the N.O (2) with the contact (6) and it works flawlessly. I recommend it, it works great.

The temperature it shows is 4 degrees higher than it actually is, my unit may be defective, but otherwise it is quite user-friendly.

Very good thermostat. I have had it for 1 year and it has not presented any problems. I have programmed it to the temperature I want, at the times I want, and it has never lost its settings. Also, the Wi-Fi signal is not lost after power outages. The room temperature sensor indication is accurate (+/- 1 degree) and can be calibrated. The mobile application is good and useful. It connects well with Google Home, you just can't program it from there. Logical. However, you have on/off, temperature adjustment, and you can also see if it is in auto or manual mode.
These are a few things. I am very satisfied and would recommend it.

Exactly what I needed. It does what it says and does it well. Control via Google Assistant and Android app. Settings for temperature deviation, program selection based on the day in automatic mode. The only small detail I would like is for the thermostat to display the room temperature when it is closed.

For its price, it is quite good. I bought it for around 50 euros. I have also bought a thermostat of double the value and it had the exact same management environment. Compared to a simple thermostat, it is worth the extra 20-30 euros. For installation, you may need an electrician. This specific thermostat is recessed. If you don't want to dig, you will need to buy an extra box-base for wall mounting

Attention, it is not mentioned anywhere that in programming, the temperature setting step is 1 degree Celsius and not 0.5 as in the manual. It may not be important for some people, but in my case, it is crucial. I have to replace it necessarily.

The connection was made by an electrician. A box is needed for sure. The 4 stars are due to the following issue. When the temperature is not working, it shows relatively accurate +/- 0.5. When it is activated and the room starts to heat up, the temperature it shows that the room has rises very quickly and the deviation can reach up to 2 degrees. This was tested with 2 digital thermometers at the same height as the thermostat. This results in the thermostat shutting off faster than it should and not reaching the desired temperature. Unfortunately, this specific issue cannot be corrected by calibration.

EDIT: It disconnected from WiFi and cannot reconnect. Numerous attempts were made based on the Greek and English manual, but none of them worked. The thermostat was reset and a new account was created for the router, but nothing.

Other people have written connection instructions, it is very simple to connect.
It requires an external box, so it is somewhat bulky, but it does not bother anywhere except aesthetically.
It works perfectly with Google Home.
I couldn't manage to put it in Hombridge for those who are interested

Electrical is simple. It has 4 terminals. Phase and neutral are connected to positions 3 and 4. Terminals 1 and 2 are not dry contacts. So, when the relay that provides phase closes, you connect the command to the burner. The two side terminals are for the extra sensor. The MAIN problem is that it disconnects from the wifi. What should I do if it doesn't do the job I bought it for? It is compact. It was installed in its place in the box, the setup was done, it connected, and after a while, it disconnected and that's it. I took it out of the box in case the wall had poor wifi reception. It connected with some hassle - it took 2-3 attempts - stayed connected for one night, and then disconnected on its own. I got it for a vacation home and I don't use it for work. During the few hours it was connected, it worked well with the smart life app and the link with Google home was established correctly

Very user-friendly mechanism. Simple, there is only one issue with some programs that change on their own. It happened 1-2 times and then it stopped! Overall, very good!

Decent product, connected easily to wifi, following the instructions on the box.
No disconnections so far and the application is easy to use, with programming or simple on/off and temperature control from anywhere.
For its electrical connection, the instructions say not to connect the command to contacts 1 and 2 for safety reasons in the automation of the solenoid valve or circulator. Contacts 5 and 6 have a protection system at 3 amps, so it is preferable to place the command on contact K1 (5) and supply power to contact K2 (6). I chose not to bridge the phase (4) since contact (2) is normal open (current passes only when the circuit is activated, i.e., when the fire symbol on the screen lights up).
So the connection was made as follows:
(4) phase
(3) neutral
K1 (5) command
K2 (6) connection with contact (2)

The thermostat is fine and quite beautiful. The weekly programs are useful. I just had to set up the wifi again after a power outage. It controls an oil burner. Three cables come to my thermostat. I mention the connection since the manual is not very helpful in this part.
CAUTION! Before interrupting the power supply from the relevant safety in the panel
L line (number 4)
N neutral (number 3)
K1 command (number 6)
bridge L (number 4) with K2 (number 5)
Very good tightening of the cables (especially in the bridge because 2 cables are inserted into the slots)
Power supply restoration.

Update 2/1/23
In the end, I didn't encounter any problems with the wifi after a power outage.

Very good thermostat....permanently connected to the house's wifi...it shows me the room temperature while I am outside Greece in the winter.

Easy to install.

The lighting is blue and stays on for 5-10 seconds after each button press.
It makes a click when the boiler opens/closes.
It has an indicator for when it is on inside the screen.
Connected to Wi-Fi very easily, I also added a widget and I really wonder why I didn't do it earlier. Tremendous convenience.

Personally, I miss some functions such as statistics!
For example, how long it took to reach temperature or how long the boiler worked, and some graphs, average-high-low temperature, etc.

A fair purchase, although I think there may be the same thing in foreign countries for 10-15 euros.

It has been working perfectly for a month.
It needs sensitivity adjustment and a box to be installed on the wall (it fits flush).
I recommend it.

The best choice for the money. I bought it a week ago and connected it very easily at home with autonomous oil heating. The old thermostat had three wires .... neutral (N), phase (L), and the third wire which was the command K1. K2 needed to be bridged with the phase L to work properly. The setting with wifi was very easy and the application works perfectly from the mobile.

It connects easily to WiFi and covers the basic need. That is, it has the necessary smart functions and most importantly, it works perfectly with Google Assistant.

"Activate the thermostat for 30 minutes" and you're carefree...

P.S. It is in the Tuya ecosystem as a device. It is not a well-known brand.

It works great. It was very easy to assemble and its measurements are very accurate. Very satisfied....
