openHAB only has 2 log files. - openhab.log & events.log

We know nothing about the item(s referenced. Perhaps the following thread can help you, especially #10.

I just realized you stated this:

> I moved the SD Card to my Rpi3

I believe there are some OS kernel level differences in between those CPUs. As stated in the other thread, that is beyond the scope of the openHAB forum. Starting a new thread here does not change that fact.

Suggestions here would be:

1. Do not do that
2. If you want to move OH to the Pi 3, import a backup of OH on the Pi 4 to a different SD card on the Pi 3.
