That’s an Item, yes? Items don’t have a .split() method (and didn’t inOH2.5 either).
It’s usually the state of an Item that you are interested in, and you’d want to be sure it was string in order to split()it.


Thanks for the clear answer ! I have changed this and the rule runs like a charme…

Thanks for fast help… i think the documentation is not clear in the definition of itemState and .state, so my mistake was that i removed the .state.toString from the old rule after my old item Name was changed by the migration Task. I was also searching for a some time for the linked channels and items after migration because in OH3 all must linked manually because of the remove of “simple” mode.
