The door and window sensor detects open and close by sensing the absence or the presence of a magnet. You can use it to tell if a door or window is open or closed then turns on or off a light, for example. You can also use the Telldus Flow app to create more complex scenarios such as notify your neighbours if the front door is open when you are not home. Use it with a TellStick Flow, then you can check if your doors and windows were closed or open even when you are away from home.
