Rule for inspecting many iteams by group

Hey,

I need an idea for a rule.

I would like to generate an email, if at least one error-channel of my knx switches to closed.
I would like to mark the item by group, p. ex. (errormail)… and I would like to put the information into the mail which item generated the error.

How can I do that?

Thanks,
Patrick
