Window and door contact

With the Homematic IP window and door contact, you can keep an eye on the doors and windows in your house or flat. Thanks to an innovative optical sensor, it replaces conventional magnetic contacts and offers reliable security.

  • Precise detection: The integrated infrared light barrier ensures reliable detection of open or closed windows and doors for a safe home.
  • Control room temperature: The sensor reports open windows to your smart heating thermostat, which automatically regulates the temperature down.
  • Concealed installation: The concealed installation on the inside of the frame of plastic windows or doors enables discreet integration into your four walls. When the window or door is closed, the sensor is not visible.
  • Suitable for many windows and doors: The sensor only requires a minimum distance of 15 mm between frame and sash.
  • Expanding your shading control: Link the window contact with your blind or roller shutter control and expand the functions in your smart home.

The Homematic IP window and door contact reliably monitors the windows and doors in your smart home. It detects the status of doors and windows via an infrared light barrier.

The sensor performs several functions: When airing, it automatically regulates the heat supply by reporting to the radiator thermostat when a window or an outside door is opened. In this way, the radiator valve can be closed when the window is open to save energy and unnecessary costs. In addition, the sensor monitors access to your four walls. If a window is opened without authorization, it activates the siren and sends you a push message via the Homematic IP app to alert you to possible dangers in your home.
