Hi Marcus, Sorry I am late joining this thread, I am just catching up.
I would also like to see this functionality. I monitor a pressure switch and the easy and cheap way to do it seemed to be to use a DS1820 temperature sensor wired through the pressure switch. If I see the temperature sensor then the switch is made. This works fine if the switch is made when the program starts but if not it never sees it.
