How to restart Nest Detect or reset it to factory defaults

If you reset Google Nest Detect to factory defaults, it will erase all settings and your Detect will appear Offline in the Nest app. We don’t recommend resetting Nest Detect to factory defaults unless you need to. For example, you might be asked to do this if you’re sending Nest Detect to us for a repair.

How to restart Nest Detect 

If you restart Detect, it will refresh its connection with Google Nest Guard. This may help fix any connection issues
it might be having. Restarting Detect doesn’t erase any
settings.

  1. Make sure Google Nest Secure is set to Off Nest Guard off. Otherwise,
    the alarm will sound when you try to restart Detect.
  2. Press and hold Detect’s button for about 10 seconds. When the light ring pulses blue, release the button.
  3. Detect will reset itself and automatically try to connect
    to Guard again.
  4. Check your Detect with the Nest app to make sure it’s working normally. If it’s having trouble, the app will tell you.
  5. If you disarmed Nest Secure earlier, remember to arm it again.

If that didn’t solve your issue, see the next section about restarting Detect by taking out its battery.

If resetting doesn’t work, try taking out Detect’s battery

Taking out the battery is another quick way to solve many common issues. It won’t erase any settings, and Detect will automatically try to reconnect to Guard after you’re done.

  1. Make sure Nest Secure is set to Off Nest Guard off. Otherwise, the alarm will sound when you try to take out Detect’s battery.
  2. Pull Detect out of its backplate.
  3. Take out Detect’s battery and put it back in.
  4. Snap Detect back into its backplate.
  5. Detect will automatically try to connect to Nest Guard again. Check your Detect with the Nest app to make sure it’s working normally. If it’s having trouble, the app will tell you.
  6. If you disarmed Nest Secure earlier, remember to arm it again.
 

How to reset Detect to factory defaults

Resetting Detect to factory defaults will disconnect it from Nest Guard, and it will stay disconnected unless you use the Nest app to install it again. However, resetting will not automatically remove it from your account, so you will still see it listed in the Nest app.

You should only reset your Detect to factory defaults if:

  • You previously removed it from your account in the Nest app, but now you want to add it back to the same account.
  • You want to completely start over and re-install your Detect from the beginning.
  1. Make sure Nest Guard is set to Off Nest Guard off. If you don’t,
    the alarm will sound when you try to reset Detect to
    factory defaults.
  2. Press and hold Detect’s button for about 15 seconds.
    The light ring will pulse blue, then it will pulse yellow.
    When it starts to pulse yellow, release the button.

    Note: After you release the button, the light will glow
    solid yellow for several seconds. If you need to cancel
    the reset, press the button again while the light is pulsing.

3. When the light stops pulsing, Detect will reset itself to factory defaults.

4. If you disarmed Nest Secure earlier, you can now arm it again.

When reset to factory defaults, Detect’s light will pulse blue. It will no longer look for activity in your home, and will be Offline in the Nest app. Or, if you’ve already removed it from your account, it won’t appear there at all.

5. Next, depending on what you want to do, follow the links below for more information and instructions.
