There are the logfiles.
Emby and openHAB logs to compare what happened when (not yet with the new version).
About the reliability. There were many entry after install and I’ve stopped logging the binding. I just restarted it few days ago and now , I don’t see any. Except the one, when I’ve removed the server (1).
I’m going to install over this weekend the new version and go with full-time logging from start.
I’ll inform you.
