# Google Nest thermostats

*Google / 9 models / 2011-2024*

> The Learning Thermostat (4th gen) and the Nest Thermostat (2020) are the Nest thermostats Google sells in the US. Both are Matter thermostats over Wi-Fi, but only the Learning Thermostat works with the sensors. No Nest thermostat is a Thread border router. The 3rd gen and Thermostat E never got Matter and still receive updates. The 1st gen, 2nd gen and 2nd gen Europe version stopped connecting to the Nest and Google Home apps on October 25, 2025. European Nest thermostats work only through a Heat Link.
