At the moment I’d just like to focus on turning it on and off, however it might be worthwhile configuring all the other features. But from my first tests, it looks like the air conditioner always needs complete settings along with the “on” and “off”.
With regards to what I need to publish to the MQTT broker… well that is a good question.
I’ve found something which might point me in the right direction: [SOLVED] IR Send with Tasmota MQTT Binding V2.5 - #2 by vzorglub
I will report back.
