Another noob question: see the attached image of my thermostat. Would it be possible to switch it for a smart one? What would I have to check? If it is possible, what would you recommend? If is don't want any 3rd party app or account?
Recently was given an Ecobee smart thermostat. Ecobee does not have a great integration for Home Assistant, but Home Assistant can act like an Apple HomeKit hub, and if you provision the smart thermostat through that, it is entirely local.
