Some enterprising engineer should start selling replacement control boards for these units. Like, drop-in, solder-on clones with 100% open source control firmware, linked with an ESP32. Zigbee/Zwave/Wifi+MQTT. I don’t mind, I’ll buy their unit and throw out their shitty controller. They’re not gonna DRM the compressor, are they?

Hell, if someone does that I’d consider opening a shop where I flip “refurbished” units with the open source board in em.

Please don't give them ideas.

It's what was done for Panasonic ACs: https://www.espthings.io/index.php/2023/09/02/esphome-panasonic-climate-interface/

I'm sure somebody will take a really close look at Haier ACs now.

There is no market for doing this at all, why would any company worth their salt do it?
