IKEA MYGGBETT Smart Door Window Sensor Wireless Home Security Alarm

This sensor keeps track of your windows and doors – helping you make life at home smoother and more comfortable.

When connected to a hub, the sensor sends a notification to your smartphone with information if a door or a window is opened.

You can combine the sensor with a smart lightbulb that turns on when you open a door and turns off when you close it – ideal for a walk-in closet.

Easy to place in different areas of the home since the parts can be mounted perpendicular to each other, opposite each other or side by side.
