Hi!
I’m trying to figure out if it could be possible to integrate my old boiler into Home Assistant. It’s a Baxi Luna3 Comfort Air, so it has a wireless remote but I don’t think it uses a communication protocol like OpenTherm or Modbus, or at least I can’t find any info suggesting this.
The remote offers many functions but we only really use two: temperature controls and cycling through central heating and/or domestic hot water; since the heating system turns on when the temperature reaches a given threshold, I think using a HA sensor to trigger an automation would do the work just fine.
I saw various projects with full-fledged thermostats but I was thinking about something really simple and relatively cheap that would also allow the boiler to be operated through its original remote in case of emergency.
Would it be possible to use a EspHome configuration to do so?
