Rest assured always knowing what’s happening at your door. Whether the door was open or closed, and by who.


August’s exclusive DoorSense™ technology tells you when your door is open or closed. So you can have peace-of-mind knowing your door is both locked and closed. You can also check your activity feed to know whenever your door was physically opened or closed.

Activity Feed + Notifications

See who comes and goes with the Activity Feed. Check who unlocked the door and if or when it was actually opened. Set-up alerts to notify when specific people arrive home. Check to make sure the kids got home from school, how long the repair service was there, or see who’s been inside if you suspect unusual activity.
