Same issue going back to M5.
Seems like all my things are in the inbox ready for re-add, except for zwave.
Edit: added the zwave stick manually again, and it came online.
Before re-adding all things from the inbox, I upgrade to M6 again.
Edit2: back on M6 I started adding my 200+ things, and suddenly the java CPU task hit the roof, as I noticed on my initial upgrade from M5 to M6. I’m not certain, because I had a good rhythm adding things, but I belive it started when I added the Ikea Gateway or it may have been a duplicate HUE item.
It’s not specific to M5 or M6 but can basically happen on any upgrade, I’ve seen it earlier.
You should be able to copy any of the jsondb backup files back to its place as @NCO wrote. But OH has to be stopped down when you do that.
If your things appear in inbox, there’s also a file called something with discovery (sorry the exact name slipped from memory) that you should be able to safely delete (= Inbox empty).
Thanks for helping out.
When on M6, there is one of my things that causes openhab2 CPU usage to hit 190% and it stays there.
I could not pinpoint exactly which one, as I was adding from the inbox like crazy.
This is exactly what happened when I did the apt-get upgrade as well.
Reverting to M5, I could add the rest of my items, and my system is now slowly coming back to life.
All my thing renames and Location grouping in PaperUI is gone though.
I have deleted the file (and did a restart of OH afterwards) org.eclipse.smarthome.config.discovery.DiscoveryResult.json
Which contained the 3 things I have in my inbox. These are actually double entries, because I have these already in the Things list.
However, the inbox still shows these things.
A manual remove from the inbox did work though.
