The smart door/window contact II Plus not only reliably detects open doors and windows and displays their status in the app, but also reacts to even slight vibrations thanks to its vibration sensor. This means it can trigger an alarm in the alarm system in the event of attempted break-ins - even before windows or doors are opened. It also automatically reduces the radiator thermostats for sustainable ventilation. The integrated button can be used as an additional control element to trigger freely definable actions or scenarios or to pause a function for a short time. The integration into Apple HomeKit, Amazon and Google Home also enables a combination with compatible products from other manufacturers.
