Nuki Smart Lock 2.0 bottom signalization segment permanently on


the bottom signalization segment is permanently on.

Nuki Smart Lock 2.0
Firmware 2.11.9

This is not listed on

What does this mean?
How can I turn it off?


What happens when you take out the batteries and put them back in?


After I take out the batteries and put them back in things are back to normal.

An explanation would be nice?


Most likely a firmware bug that only occurs under certain, specific conditions. Please report back if you notice it again.

I also have this sporadically now, how can we track down the problem?

Please contact customer support through the Nuki App (Menu > Help > Contact Customer Support) if it happens again. This will generate an error report with detailed debug information from the Smart Lock attached.

Okay so the strange Saga continues.

The bottom segment of my Nuki lock returned to being permanently on dimly, however before I got around to submitting a bug report the issue flipped to the top segment being on dimly and the bottom off.

I submitted a bug report to Nuki support, however before they could answer the issues disappeared after the lock auto locked for the night.

Waiting to see what happens next.

Hi @cdesouza ,

how have you configured the LED brightness on your Smart Lock?


Set to minimum
