Product-specific information

Nest Thermostat 

Here are a few specific things to note when setting up and using your Nest Thermostat on Google Home. 

  • 1st, 2nd, and 3rd gen Nest Thermostats work with Google Home.
  • You can ask Google Home up to 20 voice commands to control your Nest Thermostat in an hour. This helps preserve the Nest Thermostat battery.
  • Each Google Account supports one Nest home. If you have more than one Home in your Nest Account, you must choose one to use with Google Home.
  • You can only import one House.
  • All thermostats within a Nest home will be imported into Google Home. You can’t choose which thermostats are imported and you can’t remove individual thermostats after they are imported into Google Home. 
  • Only the Owner of a Nest home will be able to authorize the Nest Thermostat/Google Home integration. People who have been invited to share access through Family Accounts cannot. Here’s more on how the Owner of a Nest home is different from other people with access.
  • If you change the location name or label of your thermostat with the Nest app or on the thermostat itself, it will auto update in Google Home. However, if you change the name of a room/nickname in the Google Home app, it won’t auto update in the Nest app. Here’s how to change the name of your Nest Learning Thermostat.

  • You can’t currently set the structure status to Home, Away, or Eco.
