Homematic IP Smart Home Window and Door Contact - Optical, Plus, Digital Sensor for Efficient Heating, Monitoring Windows via App, Energy Saving, Alexa, Google Assistant, 158603A0

The Homematic IP window and door contact is part of the Homematic IP smart home system and reliably monitors a door or window. For this purpose, the window contact relies on an innovative optical sensor. This eliminates the need for additional magnetic contact and thus reduces the installation effort. The built-in infrared light barrier immediately detects whether the window is opened or closed and passes this information on the system. The "plus" design allows low-maintenance operation by the inclusion of two AAA batteries, which ensure a particularly long battery life of typically four years. The sensor takes over several tasks in combination with other Homematic IP devices. On the one hand, it ensures the automatic reduction of the heat supply via a Homematic IP radiator thermostat. On the other hand, it reliably monitors access to your own home. So if a window or door is opened when the protection mode is activated, the window contact triggers an alarm via the free Homematic IP app. This allows the user to react immediately in case of emergency. When using a Homematic IP siren, a loud signal also sounds that can make unwanted intruders escape. Installation is flexible using double-sided adhesive strips or screws on the window/door frame.
