How to Connect a Nest Thermostat to Google Home

Control your home's temperature using your voice

Having a smart Nest Learning Thermostat transforms your home environment, and using your voice to control the temperature takes the experience to a new level. If you have a Google Home, Google Home Mini, Google Home Max, or access to Google Assistant, connect it to your Nest Learning Thermostat for new functionality. With the Google Assistant app, speak or type commands to be executed by the thermostat.

Instructions in this article apply to 1st, 2nd, and 3rd generation Nest Learning Thermostats as well as the Nest Thermostat E.

How to Use Nest With Voice Commands

Once the two devices are connected, the fun begins. There are several commands that will control your Nest and the temperature in your home. Say “Hey Google," then say:

  • What’s the temperature inside?
  • Make it warmer [or cooler].
  • Set the temperature to 75 degrees.
  • Raise [or lower] the temperature 4 degrees.

Google Home and Nest both connect to IFTTT, so use the service to create your own voice commands, as well.
