Power supply of the Nuki Opener

The power supply of the Nuki Opener is independent from the building system

The Nuki Opener is operated by four type AAA batteries; no power is drawn from the building system. This prevents power theft and you can also install the Nuki Opener without your landlord’s approval.
The batteries are included in the scope of delivery and already inserted in the device.

Alternatively, the Nuki Opener can be operated with 5 V using a micro USB cable (not included with delivery).

Replacing the batteries

To insert or replace the batteries, open the housing by carefully lifting the cover over the micro USB port - this can be done easily without tools. It is best to press the button of the opener with your thumbs while simultaneously pulling the case forward at the side edges.
