Troubleshoot issues with Nest Detect

Press Google Nest Detect’s button to have it light up and indicate if it’s experiencing any issues. You can also check Detect’s status in the Nest app.

In general, the Nest app is the first place to check for any issues. It will display a message if any of your Detects need your attention. But you can also press Detect’s button to get a visual indication of any issues.

  2. Select Security  Home guard icon.

You’ll see a list showing the status of each Detect in your home.
