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 have an ecobee too (and have for about 8 years), but I thought I heard that new ecobee users couldn't get the access that HA uses.

The HA Ecobee integration requires a developer API key which ecobee no longer distributes, if you already have a key it still works, but they stopped giving out new keys a few years ago.

On the other hand, the HomeKit integration allows new users to control most of the thermostat's features locally over WiFi. I got my thermostat after the Developer program ended, and this is how I control it today. Once you install the HomeKit integration, it will discover the thermostat if its on the same LAN, and then prompt you to add it.
