I’m pretty sure you want to go with Mysa Thermostat for what you have. Use their compatibility questionnaire to confirm.

Meross works great for me.

Yes. Google nest and it pops right up on my Google home device. It will also pop up on my Alexa like 40 second later lol

I made the switch and I love it. It’s not perfect, and the devices are more expensive. But I absolutely LOVE being able to program variables in my automations (ie. If this, then that)
