The last months I had some problems on sudden restarts of my Raspberry PI with Openhabian 3.x
The reason was that I was requesting the state of a deleted item.
The second reason was to have a group the same group name in two different .item files
This fixed all my restart issues and now running for the 100th day without any problems.
Please open a GitHub issue on your first reason to get this fixed for everybody.
This is not an issue on my config. I have a persistence group and this group is defined in all my .items files.
Please what do you mean. I didn’t write anything about your config.
Your second reason in the initial post is not true.
