Learn what Nest Detect’s lights mean

Google Nest Detect uses its light ring to let you know what’s happening or if it needs your attention for things like a low battery. If you’ve turned Pathlight on, it will also light your way in the dark when you walk by. Here are the details about what the colors and light patterns mean.

The Nest app will tell you if any of your Detects need your attention and why, but you can also check any Detect whenever you want.

Press the button on Detect and the light ring will show you the status. Nest Detect typically won’t light up on its own to preserve battery life.

Steady green: When Google Nest Secure is set to Home and
Guarding, you can press the button on any Nest Detect
that’s installed on a window or door to use Quiet Open.
Detect’s light will turn green, letting you know it’s safe to
open that window or door without setting off the alarm.

Five yellow pulses: Something needs your attention. Check
the Nest app for more information. It could mean a few things:

  • Detect’s battery has less than 30 days left.
  • Your Detect needs to be checked.
  • There’s an issue with Detect’s hardware.

  • One pulse: Detect is working normally: the battery charge is good and it’s connected to Google Nest Guard.

  • Continuous blue pulses: Detect hasn’t been set up or
    added to your account in the Nest app yet. Its light will
    pulse blue while you’re connecting it to Nest Guard
    during setup.

It will also pulse blue then start pulsing yellow when you’re 
resetting it to factory defaults.

When enabled, Pathlight automatically turns on when you walk by to light your way in the dark. Pathlight is disabled by default, but you can turn it on
or off with the Nest app.
