You have ‘empty’ items in your .items, namely the three UtilityMeter68 etc.
When I try, it complains because there is nothing between {}. Didn’t you have that too?
It’s not griping that I’m aware of. But I’m using OpenHAB 1.x, too, so that might have something to do with it.
Thank you. With help from another side, I could solve it: I just don’t write {}, then it works. Just the Type and the variable Name. Then it doesn’t complain anymore.
