Custom icons in OH3 widgets

Dynamic icon not working for String item

You’ll have to set the Item metadata on the Item. Probably the easiest way to do it will be to create a test Item, configure the metadata through the UI, and then look at the code tab to see the proper field names and formatting. I don’t use items files any more and there is enough in OH 3 now that is controlled through metadata that I can’t even imagine trying to do it all in .items files. Each Item would be 20+ lines of code or more to do it all.
