I mean, that's what insteon buttons with an isy994 are all about right? The button push just tells the controller "I was pushed" and whatever you tell the controller to do with that information is what gets done. The cool thing is you can have a bank of six buttons in a standard 1-gang box format. Seems easier and less complex than NFC and a phone, unless you're using the phone as a form of authentication (something possessed), whereas a physical button is like anonymous/no authentication.
