Day one of Vacation: disassemble „smart“ AC controller to reverse engineer the thing and rebuild it with a pi pico.

@thewk

I would love to do this.

My thermostat has only really basic features unless you use the app, which requires a click-through arbitration agreement.

Stuff that crap.

@RL_Dane You cloud take add look at homematic, they are rather good and don’t require an app or internet connection.

As for my part, pi picos used to be around 5€. Cheapest offer so far 23….
