Hi David
Just to clarify your screenshot.
The Red circled item is a “Trigger” which can be used in a rule…
when
channel 'velbus:vmbgp2:***********:AA:input#CH1' triggered PRESSED // Could be RELEASED or LONG_PRESSED
then
Whereas your Blue circled text can be linked to an Item and as such can be used in a rule thus
when
Item [Item Unique Name] changed // as an example
then
