Having a smart Nest 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 to control it in new ways. With the Google Assistant app, type text to issue thermostat commands.

Instructions in this article apply to 1st, 2nd, 3rd, and 4th generation Nest Learning Thermostats; and the Nest Thermostat E.

  8. Now you're ready to talk to Nest.

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 you can use the service to create your own voice commands as well.
