What resetting does

Nest Protect will still detect smoke and CO

Erasing all settings on your Nest Protect does not change its ability to detect smoke or carbon monoxide. The alarm will still sound if either are detected. 

Resetting Protect to factory defaults:

  • Disconnects it from other Nest Protects, if you have them
  • Disables notifications sent from that Protect to your phone or tablet 
  • Deletes Wi-Fi settings
  • Erases the room name that you chose, Pathlight and other device settings 

Steps to erase all settings on Nest Protect

  • You cannot erase the settings on your Nest Protects with the Nest app.
  • You’ll need physical access to your Nest Protects in order to erase all settings and must perform these steps on every Nest Protect you want to reset. 
  1. Press and hold the button on Nest Protect. It will chime and the light will turn blue.
  2. Release the button when Nest Protect starts speaking its version number.
  3. Nest Protect will start an audible countdown and tell you it’s erasing all settings. Cancel the reset by pressing the button again.
  4. After a few seconds your Nest Protect will reset.
  5. Remove Protect from your account, if needed.
