Thermostat most compatible with HA

Configuration Z-Wave

Are you warning me about something specific? I just want to turn it on and then turn it off. No fancy scheduling.

Well let me share my experience.

I dont have thermostat. I have Buderus furnace logamatic 2107. And some guy in Germany have the same one. But this guy being a iot engineer decide to hack this thing. After he done it, he made esphome firmware with pcb that he sells. And this thing is working with this furnace. It’s actually great that he made this pcb and wrote firmware for it.

Lonfg story short, there is not thermostat that will reliably work with your furnace. You can go with property config if it is supported by ha, or you are just out of luck.
Maybe someone with more skill will write firmware for it in esphome but I doubt it as they are now make this things out of plastics and no one will invest its time to make some plastic crap to work.

Unfortunate this is the reality.

I had two Trane ZWave thermostats for years. Recently one quit working. I replaced it with a Venstar T2000. It is 100% local control, works via WiFi and has been great since I purchased it. I set all my HVAC controls locally, so no need for any fancy extras built into the thermostats. I want local control, good reliability and easy configuration in Home Assistant. This thermostat checks all those boxes.

Do you have a screen shot similar to Busman please?

25

Nope. Just repeating that the thermostat expects to have z-wave control it when it’s included in a z-wave network.

HA can turn it on or off.

26

Just to be clear, I have 2 of these in Home Assistant and have never had “issues”. I can control them as expected and they update Home Assistant as expected. What exactly are you referring to?

27

That’s good to know. I had seen a few threads. I now have both the Go Control and I just ordered the Honeywell.

28

Do you need a thermostat? I just have a couple of temperature sensors that I average, and a couple relays to turn the furnace or a/c on, using generic thermostat.

Honeywell T6 or Ecobee premium via HomeKit. I have 4 T6 and 2 ecobees they work flawlessly and no cloud dependency whatsoever so they work during an internet outage. T6 an are zwave so you’ll want a good mesh setup. I don’t recommend NEST, I had two and removed them, the integration is cloud based, hard to setup and not reliable.

What about this?
An OpenTherm interface is mandatory.

Or build one yourself with the Master shield, an ESP and ESPhome.
