NUKI Binding - Keeps INITIALIZING - Could not handle Exception

[HaKuNa (Remo M)]

You are right, the same should be possible in openHAB.
But try removing the things definitions from yout file and add the bridge and the smartlock via PaperUI.
If both things came online this way, then the documentation is probably wrong.

New openHAB2 Binding for Nuki Smart Locks

It turns out that the bridge hadn’t retained the callback, I have entered it again and it works. I’ll keep an eye out for any updates and test again if it helps, otherwise I’ll wait for the released version.

or things definition like that:

Bridge nuki:bridge:NukiBridge1 [ IP="192.168.x.x", PORT=8080, APITOKEN="xxxxxx", CALLBACK_PORT=8081 ] { 
  Thing smartLock FrontDoorLock [ NUKIID="123456789" ]
}
