ONLY zwave binding… that was the odd thing.

I did the following now and that worked and the stick is found again during OH startup

Did two things in parallel and one of them fixed it: Installed this library: [RFXCom issue on RP3 - #5 by marky](https://community.openhab.org/t/rfxcom-issue-on-rp3/18282/5) And did an apt-get update/upgrade and am now back online. Hope one or both help your install (I’d start with an upgrade).
