Comment on Thermostats compatible with selfhosted Home Assistant
billwashere@lemmy.world 2 days agoI like this one but I’m not sure why a $5 microcontroller, 4-5 relays and a screen costs so much. And it’s not even a great screen. I kinda like it to be more of a full color LCD screen. Just my opinion.

Welcome to the world of electronic gadgets. You’re right there’s nowhere near $100 worth of hardware in this thing. I’d also love a color touchscreen. But I’d rather a color touchscreen that I could integrate in HA than one running some proprietary cloud connected ThermostatOS.
You could do that yourself- put an old tablet on the wall, run power to it, then get something like a zooz zen16 multi-relay or an ESPHome relay board to drive the hvac. Then the thermostat becomes a totally software defined virtual thing in Home Assistant that pulls data from a temp sensor in the room and controls the HVAC as appropriate.
