Homematic IP Window & door sensor

(This text is machine translated) The Homematic IP window and door contact for concealed installation unobtrusively monitors doors and windows within the Homematic IP smart home system. The 15 mm flat sensor is glued to the inside of the frame in just a few simple steps, where it reliably detects the current status of the window with the help of a light barrier. Once installed, the window and door contact enables the room temperature to be lowered automatically during ventilation or the Homematic IP siren to be triggered if third parties gain unauthorized access. A built-in sabotage contact reliably detects unwanted manipulation or dismantling of the sensor. The Homematic IP app also shows the respective status at any time. Two micro batteries supply the sensor with energy for up to five years.
