Homematic IP window and door contact - optical

The Homematic IP window and door contact is part of the Homematic IP smart home system and reliably monitors doors and windows. For this, the innovative sensor does not rely on the usual magnetic contacts, but on a sophisticated optical sensor. As a result, the otherwise additionally required magnet becomes superfluous, which reduces the installation effort. The built-in infrared light barrier monitors the door or window and recognizes the open / closed state.
In the Homematic IP system, the small sensor takes on several tasks at the same time. On the one hand, it ensures that the heat supply is automatically reduced when the fan is running, by notifying the Homematic IP radiator thermostat as soon as a window or an outside window is opened. Particularly practical here is the possibility of defining a reporting delay for doors that are used several times a day in order to avoid constant opening and closing of the radiator stop valves. On the other hand, the sensor reliably monitors access to your own four walls when you are absent. If the alarm mode is activated, the Homematic IP siren can be activated in the event of an unauthorized window opening. The app also sends a warning message to the user in the form of a push message. He is thus given the opportunity to react promptly to the dangerous situation.
The small sensor, which weighs 30 grams, works so effectively that it works for around two years with the energy from an AAA battery. If the battery capacity is running low, the Homematic IP app reports. The low weight of the sensor allows reliable attachment using double-sided adhesive tape. This is supplied together with an additional brown cover cap and a reflective foil. If the window or door material does not allow it to be attached with adhesive tape, the two tiny screws supplied can be used.
