Compatibility answer

Yes. The Nest Thermostat (2020) has a Matter certificate, and its record lists Amazon Alexa.

What is established: the Nest Thermostat (2020) matches CSA certificate CSA23170MAT40683-50 (February 2023), and its record lists Apple Home, Amazon Alexa and Google Home. It connects over Wi-Fi, so it does not need a Thread border router. Google added Matter support in firmware 1.3–10 in June 2023.

How it works with Alexa: Google Home is used for the thermostat’s setup and remote features. You then add it to Alexa as a Matter device, which needs an Alexa device that works as a Matter controller. Which thermostat controls Alexa shows can differ from Google Home.

What is not established: whether a specific unit has current firmware. Check that the thermostat is updated before adding it to Alexa.
