From here
I want to be able to have a rule machine trigger for any button/any action on a button device -- so i dont need to have 15 triggers on my Inovelli dimmers to know if someone is interacting with it. Then it would be easy to have a rule with a trigger that could set a hub variable to the current date which can tell me the last time the switch was touched.
as bertabcd1234 pointed out, the 15 trigger idea can currently be minimized to two by using a custom attribute for held/changed and pushed/changed. that's pretty good.
