If your Mitsubishi uses IR for it's remote, this probably would work: https://github.com/geoffdavis/esphome-mitsubishiheatpump https://github.com/geoffdavis/esp

If your heat pump talks to MEL cloud (Mitsubishi's cloud thingy) then this should work: https://www.home-assistant.io/integrations/melcloud/ https://www.home-assistant.io/integrations/melcloud/ I have yet to buy a "smart" device that I haven't been able to control through HA. The Broadlink RF/IR bridges even makes anything with a remote automatable. Seriously, If it wasn't for Home Assistant, the "smartness" of smart devices would be next to useless.
