Complete everything as is in the description. Temperature measurement is absolutely perfect. It was easy to connect to the ZigBee gateway and add the device to the SmartLife application. In the SmartLife application the battery status is displayed more accurately (in numbers) than on the thermostat itself.
I found only 1 disadvantage. The temperature difference can be set to the lowest value of only 0.5 Celsius in the settings. In practice, when it is set the desired temperature, e.g. 21 (Celsius) -> the thermostat starts heating when the temperature drops below 20.5 and turns off when it exceeds 21.5. So it keeps a range of 1 Celsius at a temp.diff setting of 0.5. It would be ideal to be able to reduce the temperature range to 0.5 Celsius or to start heating when it drops below 20.5, but the heating should be turned off when it reaches 21.
It would be ideal if this setting could be changed somehow – via SmartLife…?

Not yet install there is no fixing bracket

It fascinates Me, especially the easy installation with the pegables, it also brings to place it by drilling for those who want to fix it like this

The second version of the device is the latest version and works excellently and correctly thank you

Works great with Mi hub2
