Some Items not displaying in BasicUI

Setup, Configuration and Use Items & Sitemaps

Seamingly random Items are just not shown… The place and label are there, just no value.
And also no errors in logs.

All Items display fine in HABPanel.

Any ideas?

Update: The same Items also do not show up on Android OpenHAB app.

I think I found the problem. My Item definition was missing the part in squared brackets. I did not know it is needed for every item.

Number myFirstItem “temp [%.2f]”

That solved most of the missing items, but I still can’t get the Date to work. It is type String in PaperUI, and defined like this in sitemap:

Frame label=“Date” {
Text item=DateString
}
