Nuki Door Sensor

With the Nuki Door Sensor, you never wonder whether you properly closed and locked your door. It works in combination with your Nuki Smart Lock 3.0 or higher. You attach the door sensor to the door frame and the accompanying magnet onto the door. After this, you can easily set it up via the Nuki app and connect the sensor to the smart door lock via Bluetooth. You can then always see the status of the lock and the door on your smartphone. If you want, you can also get a warning when the door has been open for a long time, the locked door is being opened, or when it locks while the door is still open.
