You can look at Nest Guard’s lights to see the armed status or press the Info button to hear more details. With the app, you can see if it’s armed or disarmed, who armed it last, check Nest Detect status, and more.

How to check Security status with Nest Guard

If you’re at home, you can just glance at Nest Guard’s light ring to see what’s happening. Both the colored light ring and the icons in the keypad will light up to show you what’s happening.

When the light ring is:

  • Green:someone has pressed the button on a Detect and
    turned on Quiet Open.
  • Red: the alarm is sounding
  • Yellow: something needs your attention. Press the Info guard info icon  
    button and Guard will tell you what it is.

The security level icons will also be lit up:

  • Blue: the system is armed in the corresponding security level
  • Green:someone has pressed the button on a Detect and turned on Quiet Open
    The Info guard info icon   button will also light up and change color. Simply press the button and Nest Guard will speak and tell you the details.
  • Off: no issues have been detected
  • White: one or more potential issues exist (such as a window left open). Your Guard will let you know which window or door is open. You’ll still be able to arm your system and Guard will ignore that window or door until it’s closed.
  • Yellow: an issue (such as a low battery) needs your attention. Your Nest Guard will let you know what’s wrong. You’ll still be able to arm your system.
  • Red: a critical issue (like a hardware failure) needs your attention and will prevent arming.
