Thermostat recommendations? (lemmy.today)

What are people on Lemmy using for their home thermostats?

I'm in the US with a packaged HVAC system (cool+heat) and was looking to buy a new thermostat, but I wanted to make sure it's highly compatible with Home Assistant.

Ideally, I'm looking for something that speaks Matter over WiFi or Thread. I would like to mainly control it via HA. Everyone in my household are Android users (not totally sure if that's important?). Also, it would be nice if I didn't have to connect it to the cloud.

I was considering the Meross Smart Wi-Fi Thermostat, which seems to check all of the boxes. I was wondering if anyone here uses this thermostat.

Another one that seemed interesting was the Siterwell Smart Thermostat GS368M, although this was just announced very recently and who knows when/if it'll go on sale.

I use a z-wave thermostat (Honeywell T6 IIRC). If you want to avoid the cloud WiFi probably isn’t what you want. I’d look at z-wave or zigbee models. Some thermostats also require a common wire (C-wire) which means they’re powered by the HVAC system itself rather than using batteries. This is especially true of WiFi models.

Seconding the t6. It's been solid and does everything I want in HA.

I even got a rebate from my electric company for the full price of it which might be worth looking into.

Had mine for a while now and it's been rock solid. Love it.
