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.
To replace the batteries, the cover of the Nuki Opener can be lifted off.
Alternatively, the Nuki Opener can be operated with 5 V using a micro USB cable (not included with delivery).
