Smart Air-conditioner Controllers

Air-conditioner control here works by infrared: a hub with a built-in IR blaster learns the existing remote, and automations, schedules and voice commands then talk to the hub. That makes line of sight the practical constraint, since the hub has to reach the indoor unit's receiver, and it also means the system reports the last command it sent rather than what the air-conditioner is actually doing. The Hub M3, Hub M200 and Camera Hub G3 are the models with infrared control; the G350 does not have an IR blaster.
