I need to relocate my thermostat as the hallway it's currently in doesn't have any radiators so temperature doesn't really follow the rest of the house. Need to work out how to wire it into the boiler to work wirelessly but should be simple enough.
It means I'll have a spare blanking plate in the hallway and I was thinking of putting a PiW and small touchscreen in there so can still control the temperature via Home Assistant.
Just pondering how to get power to it. There are two wires (probably 1.5mm I think) running back to the boiler cupboard where there is also a plug so should be able to do something but not sure what. I'm thinking USB power supply in the cupboard to a USB plug where only the power pins are connected and then these soldered to a micro USB at the other end to connect to Pi which then powers screen through GPIO.
Does that all sound reasonable? Not sure what kind of length run you can have with USB power.
