Smart thermostat suggestions with no C wire?
My current thermostat is battery operated. I bought an ecobee but realized that I can’t use it because I have no C wire. I’m renting and the furnace is in the ceiling I can’t access it, so I can’t install an adapter either. Basically back to square one.
I want a smart thermostat but not sure if a battery operated version exists that doesn’t burn through batteries.
Any suggestions on the best way to upgrade?
