With an ideal positioning you can achieve highest reliability of the door status detection
As a Nuki accessory, the Nuki Door Sensor offers variable mounting options on the door and the door frame. This way external influences can be reduced, increasing reliability.
Depending on your door, the optimal position for sensor and magnet differs:
The Nuki Door Sensor is suitable for plastic and wooden doors. Sliding doors and doors made of metal are not supported, as they influence the measurement of the magnetic field strength.
Option A - The door and the door frame are at the same level
If the door and the frame are at the same level, the magnet must be mounted parallel to the Nuki Door Sensor on the inside of the door. The distance between sensor and magnet must be in the range of 0.5 cm and 3 cm.
Option B - The door and the door frame are not at the same level
If the door and the door frame are not on the same level, position the magnet on the edge of the door at a 90° angle to the sensor.
The distance between magnet and sensor should be between 0.5 and 3 cm for this mounting option as well.
Note: Nuki Smart Lock 1.0 and 2.0 are not compatible with the Nuki Door Sensor. However, the Smart Lock 2.0 has a built-in door sensor (beta). You can find an installation guide for the door sensor of the Smart Lock 2.0 here.
