Google Home runs the Nest Thermostat (2020), a US wall thermostat that gained Matter in a 2023 firmware update (version 1.3-10). Matter is what lets it pair with Apple Home, and Home Assistant has an official Nest integration. It is built to work without a C-wire, though some systems still need one. SmartThings support is not confirmed.

| Platform | Works? | Details |
|---|---|---|
| Matter | Yes, over Wi-Fi | CSA lists Google's Nest Thermostat as Matter certified over Wi-Fi (firmware 1.3, Feb 2023; later listings cover 1.3a and 2.2). No model number is given, but firmware 1.3 matches Google's update history: Matter arrived in version 1.3-10.[2],[3],[6] Other Matter smart thermostats |
| Apple Home | Via Matter | Through Matter: add it to Google Home first, then link it to Apple Home. Google caps a thermostat at 5 Matter apps. Needs an Apple home hub.[2],[3] |
| Google Home | Yes | Set up and controlled in the Google Home app.[1],[2] |
| Amazon Alexa | Yes | Through Google's Nest skill for Alexa, enabled from the Google Home app. Google's tech specs say it works with Alexa (needs a compatible device).[1],[4] |
| SmartThings | Unconfirmed | No Google or Samsung page found lists this model. Only a SmartThings forum post mentions a Nest thermostat over Matter. |
| Home Assistant | Yes | Official Google Nest integration using the Smart Device Management API, which Google says supports all Nest thermostat models; Google charges a one-time US$5 Device Access fee. Matter is a second route.[5],[7] |
“Via Matter” means you add it with that platform's Matter controller instead of a brand skill or app. “Unconfirmed” means we couldn't find an official source either way. How we verify.
