Nuki Lock Pin Status - PIN Set but invalid

[siggi60]

Hi,
i have a little Problem with my Nuki Hub. I allways have one Failure, see Topic, and i'm not able to handle it.
I tried all Keys i have so far and also different times "#" to delete it. What's wrong?
And sorry, english isn't my native Language :-)

Thx for your help
Siggi

same issue here: I have set the correct PIN code for the Nuki Lock, but the status is still show as "PIN set but invalid"

[technyon]

I see that you've set "Register as: App", which means you enabled the "Nuki Bridge is running alongside Nuki Hub" setting. This is not recommended, not sure if it's related to your problem. Do you also use a Nuki Hub?

[siggi60]

No, only Nuki Hub and now it's "Register as: Bridge"- I hope you meant the Nuki Bridge.
Now, after playing around my Lock isn't connected any more :-/

[siggi60]

Just reconnect after total reset - no PIN set - Error "PIN set but invalid" is back :-(

[staudtm]

Have you set
Basic Nuki Configuration - Nuki Smartlock Ultra/Go/5th gen enabled
correct?
Only ENABLE if you have really a Nuki Smartlock Ultra/Go/5th ;-)

[siggi60]

No, only Nuki Lock

[siggi60]

Don't know why, but now its running :-)
