Can't configure new sensor - what am I doing wrong?

[caladrien]

I'm new at this integration but since I realized, that I do not have to fill my calendar manually anymore, I'd like to use this integration.

So fare it is strait forward. Calendar already working for my. Filtered out the relevant collections:

What I now wanna have is one sensor for each type off collection showing me the remaining days till the collection. I thing the UI config is pretty straigt forward but somehow I make a mistake and i don't know where.

Where do I make a mistake?

I think my question is a kind of basic one but I couldn't find a sort off "Getting Started" document...

As for the Getting Started document: there is this, but it is mainly focused on yaml configuration and does not describe exactly how to set this up using the GUI, but the configuration variables match 1:1 the one in the GUI.

It looks like you put paper into the types filed, but the Calendar shows Altpapier the types field describes which entries to use to calculate the value, as there is no collection entry named paper it becomes unknown. If you leave the types field empty, it will match all collection entries.
