When your SkyBell is powered down and then re-powered, it will power back up with the Do Not Disturb function engaged. The reason for this is so that the bell doesn’t ring while the device is rebooting. Please turn off "Do Not Disturb" after your SkyBell is again fully charged.
Please note that it takes 2-3 minutes for the SkyBell to update after switching the motion sensor or "do not disturb" setting on or off. Please give SkyBell 2-3 minutes after each time you switch that setting for it to update. Both of these settings can be found by tapping on your device from the "home page" of the app.
