Door sensors.

If you have a sensor on your door, the Ambient Home app shows you when the door is open and closed.

• If your door has been open for longer than one minute, you’ll see a notification from Ambient on your phone’s lock screen.

  

• In the Ambient Home app, you’ll see a message in the top left corner of your lock that tells you whether your door is open or closed. Note: Your door may be locked or unlocked while it is open or closed.
• If your door has been open for longer than one minute, you’ll see a message under the lock of the open door.
