if i start openhab without it and put it there later, all runs ok

is there a solution to fix this?

Hello WiredLife,

as I just found out, it has to do something with the serial handler.

So please install add-on wmbus as latest, so after Update install bindings like EnOcean oder ZWave (depends what you need) first, and if everything is up and running (give at least 15-30 minutes I think), then put the wmbus.jar in the addon folder.

For my system this works.

Otherwise if wmbus is installed first, it seems to use a wrong serial or has got an unresolved dependency in newer version of openhab. Please let us know here if it works for you too.

Just one additional hint: same procedure works with 3.2.0-1 and wmbus binding snapshot 20210805 too. Wait until everything ist installed, up and running, after that put Snapshot in adding folder
