Hello,
I have a working instance of OpenHAB 2.5, with all things defined in UI and items, rules and sitemaps defined in files.
Today I wanted to try out OpenHAB 3.0, installed bindings, configured things in the UI and uploaded some items files.
The items do appaer in the configuration view, but they all show NULL on the right end of each item.
I guess something is missing in the item definition?
