Having a smart, connected Nest Thermostat can transform your house, but connecting it to a Google Home and using your voice to control the temperature can take the experience to a new level. 

If you have a Google Home, Google Home Mini, Google Home Max, or access to Google Assistant, you can connect it to your Nest Thermostat and control it in new ways.

Why Should You Connect Your Nest to Google Home?

All Nest thermostats up through the 4th generation, including the E version, can be connected to a Google Home, allowing you to control the temperature using your voice. Using the Google Assistant app, you can also use text to type your thermostat commands to the virtual assistant.

Adding a Google Home Mini is a cheap and convenient way to extend thermostat controls to a remote part of your house, away from the main control unit. It can also be a fun and easy way to let guests control the air flow by saying, “Hey Google, set the temperature to 75,” without teaching them how the thermostat works.

How to Connect Nest to Google Home

Once you have your Nest thermostat installed and connected to Wi-Fi and Google Home, you can proceed to connect the two devices.

Customize Rooms Later

If you need to change the name of the room you told Google Assistant your Nest was in, you can also do that:

  1. Under Home in the Google Assistant app there will be two sections at the top: Device and Rooms.
  2. Tap Rooms.
  3. Select the pencil icon next to the name, then select a room location.
  4. Select Done in the top right corner.

How to Use Nest With Voice Commands

Once the two devices are connected, the fun can begin. There are several commands you can use to control your Nest and the temperature in your home.

Try these voice commands to get started by saying, “Hey Google…”

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

These are natural commands Google recommends, but you don’t always have to be so specific. Nest will also respond to commands like, "Set the thermostat to [75]."

Using IFTTT to further enhance your Nest

Google Home and Nest both connect to IFTTT so you can use the service to create your own voice commands in the future. For example, here’s a popular one for running just the fan, without AC.
