I'm having an issue connecting the nest learning thermostat from one of our rooms in our flat. It seems to connect and then after an hour or so it loses connection and won't reconnect. There are no issues connecting from other rooms and currently have it in the hallway where it works ok. I've read that walls, mirrors and things like refrigerators can block signal (which would all come in to play in this room) but we had our previous wireless thermostat in this room and it worked fine. Bit disappointing frustrating considering how much more money this cost than our previous thermostat but hoping maybe there is a fix for this?
