What is wrong here?

I think I’ve found a solution, so I’m sharing it with the community. It’s just a shame that such important information isn’t communicated in any special way with the new version of OH…

According to the information:

Note

openHAB version 5.1 and above no longer support default strategies. If you have a Default under Strategies you should remove it. Also make sure every Items definition has one or more strategies defined.

Persistence

So I defined a new strategy and it seems to be working.

Well, I’ve been hit by this as well, but to be fair, what you say is not true.
It’s listed in the release notes and breaking changes. I was warned and able to cope with that.
I agree though that communication on that was fairly bad.
