Air have a "dumb" air conditioning unit. It has only an infrared remote and nothing more.
I thought about buying something to mimic the signal to add a remote in #HomeAssistant. But most of the time I use the same settings and just wanted to make it on or off.
So I put it in a smart plug for 5€ and add a finger bot for 6€ and voila. I have a smart air conditioning unit and can control it via Home Assistant and see it's status.
As a bonus I know exactly how expensive it is to run these things (holy cow 😱). But as I'm extremely sensitive to heat it's definitely worth it.
