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.
