Very good quality and above average problem only in the connection of the phone excellent performance in the control and maintenance of temperature accurate temperature

I haven’t installed

In the absence of trying everything perfect

Two sensors zigbee version, both have the same bug.
As soon as you press the button to light the screen, the data is no longer sent back to the zigbee Bridge afterwards. Even after several hours and even if the temperatures and humidity change.
Obliged to restart a pairage between the sensors and the zigbee Bridge.
So work as long as one does not need to light up the screen to see the time or date.
Further on my copies, the light for the battery level is not present.
According to the seller, the version of the software is frozen, so no update expected.

Ok! Fast !
