I got the Meross Smart Matter+Wi-Fi Thermostat MTS300 US running today.

In case anyone is curious about what gets exposed to Home Assistant, here it is!

The installation was some what haphazard. I think I was supposed to install with the Meross app. But I’m not sure if that actually was needed. I think I installed via scanning the Matter code in Home Assistant… and then later it appeared in the Meross app. 🤷

The Meross app exposes fan controls. Also child lock. You can also create a schedule in the Meross app. None of these features are visible in HA. (Also cannot control display brightness via HA. Sad.)

Side question: how do y’all create a schedule for your thermostats? I feel like I shouldn’t use Meross’ scheduling features and I should keep all the smarts in HA, right? I guess I should create Automations and trigger them based on time of day?

    Depends how you want to use it.

    We don’t have set schedules because utility prices are insane. Instead:

    • Manual control as desired by setting thermo, with shortcut buttons for set temps
    • Button to blast the heating for an hour regardless of temperature and cut off afterwards
    • Presence detection to shut it off if it’s on when there are no users home (also lights)
    • Watchdog to turn off and keep trying to turn off if heating has been on too long or without demand. Can happen if something sticks or drops off
