Troubleshoot Nest Thermostat bluetooth connection

During Google Nest Thermostat setup, the app will try to connect your phone to the thermostat over Bluetooth. If there’s a problem and your phone can’t connect to your thermostat, follow these steps.

This article only applies to the Nest Thermostat.

How to tell which thermostat you have

1. Check your phone’s Bluetooth

  1. Check that your thermostat is on. If the screen is off, tap the touch bar.
  2. Make sure your phone’s Bluetooth is on. You’ll usually see a Bluetooth  icon at the top of your phone’s screen.
  3. If Bluetooth is already on, turn it off for a few seconds to reset the connection. 
  4. Switch Bluetooth back on and try connecting to your thermostat again.

2. Move closer to your thermostat

Bring your phone within 12 inches (30 cm) of your thermostat, and keep it there until setup with the app is complete.

3. Disconnect other Bluetooth devices

Other Bluetooth devices can prevent your thermostat from connecting to the app.

  1. Go to your phone’s Bluetooth settings
  2. Remove any connected devices. You can reconnect them when you’re done with thermostat setup.
  3. Try connecting to your thermostat again.

Note: These steps may be different depending on your phone. For detailed instructions, refer to your phone’s manual or the manufacturer’s website.

4. Check the thermostat batteries

Double check that you’ve removed the battery tab and that the batteries are properly seated. 

  1. Pull off the thermostat display and remove both batteries. 
  2. Make sure there isn’t a leftover piece of the clear battery tab.
  3. Put the batteries back in, the display should turn on when the batteries are seated properly.
  4. Press the thermostat display back onto the base until you hear a click.
  5. Try connecting your phone to the thermostat again.

5. Check for wireless interference

In rare cases, interference from electronics (other Bluetooth devices, microwave ovens, etc.) can block a Bluetooth connection. Turn them off until you’re done with thermostat setup.
