Thank you for your post: I deeply appreciate your efforts for letting non-experienced user to take advantage of openHAB.
Actually, I mentioned you because I was only wishing to understand the question of what is stored in metadata and about the small widget issue that I found.
It was not my intention to ask for help on textual configuration, but simply to let other know about its limitations.
I fully understand your point and, while porting my OH2.5 to OH3.1 with text files, I’m practicing with adding new things and items with the MainUI, keeping track of the YAML code in text files.
The other observation that I described was about a widget YAML, but I will open a separate thread because it is only marginally related to writing metada via configuration text files.
