Which Google Nest thermostats should I buy?

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.

Identify a model

Pull the display off and look at the base. Or open the thermostat's info menu in the Nest app, which shows the model, serial number and software version.

Identifying clues

How facts are sourced: every cell cites its source below

Europe is different. A European base has 2 connectors (T1 and T2, or unlabelled) and never wires to the boiler. Every European Nest thermostat works through a Heat Link. A high-voltage base does not mix with low-voltage parts. The 2nd gen Heat Link has 1 status light, the 3rd gen Heat Link has 3 status lights with OpenTherm and hot water control, and the Heat Link E has 2 status lights and runs on batteries.

Google does not publish model numbers for the 1st gen, 2nd gen or the European models. Unofficial lists give T100577 for the 1st gen, T200577 (US) and T200477 (Canada) for the 2nd gen, and T200377 (UK) and T200677 (France, Netherlands, Belgium) for the 2nd gen Europe version. They are unconfirmed.

The names are similar. The Nest Thermostat (2020) is a separate product from the Nest Learning Thermostat and from the Thermostat E. Unlike the 3rd gen Learning Thermostat, it has Matter.
