Did you find out how to enable myopenhab.persist?
I’ve been fighting the same issue during last week. openHAB doesn’t seem to care at all what I write in the myopenhab.persist file which is the place I want this setting stored. I got it to work in PaperUI by checking the item boxes in normal mode. But when I enter stuff in expert mode it doesn’t work. Also tried to add only a myopenhab group (just as described in this post) in expert mode and in persist file with no success.
