DWDUnwetter does not clear old Values

Add-ons Bindings
1

I’m using DWDUnwetter binding in OH3, and it seems, the “old” values don’t get purged from the items . I have set the Thing to display 3 warnings. Right now DWD had none for my cell, and I still had the last one (3) as values on my items.

UID: dwdunwetter:dwdwarnings:home
label: DWD Unwetter Home
thingTypeUID: dwdunwetter:dwdwarnings
configuration:
  cellId: "12345678"
  refresh: 30
  warningCount: 3

It seems, the last one (3) was issued back in 2020-12-19… it could be, that I moved from a milestone to the final version around that time (not sure on the exact date…), so it could be an old fragment, but perhaps there’s a bug in the purging of old items.
Right now just a few seconds ago DWD issued another warning for my cell and the (1) was updated from NULL, but (3) still stands with the old values.

Hi Thomas,

I experience similar issues, I have two warnings set, but I only get the first one. Warning2 has never changed even though warnings should be present…

I have to say that I’m using the text config - have you configured the bridge in the UI?

I completely switched to GUI-configuration with OH3…
And as you say that, I do have (4) channels, though I set warningCount on 3…?

But for now I only got two warnings in parallel (“Glätte” und “Frost”). In December I also got “Nebel”…

I switched to GUI now, the number of warnings matches my settings, I still only get one warning where 2 should be present.
I think it has to do with the different Cell IDs…
DWD displays the warnings on all levels (Kreis, Gemeinde…) but not every CellID gets all the warnings it should…
