Trigger question

[Rumo]

I'm looking for a trigger:

Example:
I get a value at 8:05 pm and then not worth more. So there must be a trigger, which strikes after n minutes if no value was supplied. The item has the value text

see nodata function in the manual

Thx for your reply. I skipped the page in the manual. ^^
It works fine.
