This adhesive wall-mount bracket for the Hive 2 Thermostat is minimalist. The installation is straightforward, it's non-destructive and fully reversible. If the wall is clean from debris and not wet, the adhesion is impressive and it will safely hold your Thermostat. It is minimalist and stays almost hidden when the Hive is in place. If you have multiple brackets it will allow you to move your thermostat in different rooms, so you will always have the target temperature in the room of interest. 
 
This is offered in White, Grey and Black.

Please note that this doesn't work for the Hive Mini!
