Thermostats compatible with selfhosted Home Assistant

Thermostats compatible with selfhosted Home Assistant - Lemmy.World

Hi! I am running Umbrel on a Raspberry Pi 4 and I have “Home Assistant” installed in it, I oly have some smart lights connected to it. I would like to integrate a Thermostat with HA. But I am a bit overwhelmed with the different types of connections (Z-wave, Zigbee, Wifi, …) Do you guys have any kind of recommendation, what connection is better? I would like to keep it local (or connecting remotely via Tailscale) but I would like to avoid any cloud or third-party server solution. What thermostat hardware can I buy?

That is the one you want. Honeywell t6 pro Z-Wave version, specifically that link which is the newer Smart start version.

Z-Wave is 100% local, not Wi-Fi, and secure.

I use these in my house and couldn’t be happier.

I 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.
