Status and warnings at a glance
The status of your door is not only shown in the Nuki app but also directly on the Smart Lock by a LED signalization on the rotating ring.
Note: In addition to the illuminated ring, the Smart Lock 3.0 has a red LED in the upper segment of the ring. This LED is used to display errors and warnings directly on the Smart Lock. If the red LED lights up, open the Nuki app to get further information about the error or warning and troubleshooting steps.
