Sengled Door Sensor

Use the Sengled Smart Window & Door Sensor to make sure that your home is just the way you left it. Install it on any door jamb or window frame and check the app to see if it's still shut when you're away from home. Automate your lights based on if the door or window is open or shut or use the Sengled Home app (iOS/Android) to have the lights turn on as soon as the front door opens.
