What is your self-hosting setup for home thermostat? (lemmy.world)

I'm not sure the best way to ask or if there is a better community to post...

I'm hoping to use my home server to control my home thermostat but not sure where to start.

Does anyone use Home Assistant for this? Another software?

I'm not sure if I'm allowed to ask about hardware here, but are there things to be aware of in making sure that a wifi thermostat is best suited for the job?

I've got a couple Honeywell T6 z-wave thermostats that work great and didn't cost a lot. I control them through home assistant with some custom code to set them on a schedule, but they can also still be operated manually if needed.

I have the T6 as my main but I cannot do per-room heating because my Sonoff TRV's cannot talk to it in HA. I got the T6 before working with HA though. In my country the T6 is WiFi and you need the Resideo app.

Does the Honeywell T6 give you separate control of temperature and fan? That is, can you turn air circulation on/off, even when the temperature wouldn't trigger heating/cooling?

I've been watching pm2.5 in my house, and the HVAC filter does a pretty good job of keeping it down if I run the fan, but that fan takes a lot of energy, and I'd like to turn it off when the air is pretty clean.

I believe so, my system is baseboard so I didn't use a fan. There is a fan control option on the device. The instructions say it can do auto, on, of, circ.

TY. Looks like the T6 is pro-only. Googling around, it looks like ventilation control may be one of the things that separate their pro-level T6/T10 from their DIY-level T5/T9. That's disappointing.

Is it? I guess I don't know the difference... I installed mine myself but my system is also dead simple - only 2 wires. My first thermostat was just a bi-metallic strip. 😀
