This is going to be difficult to describe but here's what I'm hoping to do. My car has a programmable Homelink button (like most new cars) and I can program it to open common garage doors. Instead if it opening a garage door though, I want it to trigger a program within the ISY. IOW, when I arrive home and activate the "garage door opener" in my car, instead of a garage door responding, a program within the ISY runs. Is this possible and if so, what do I need?
Thanks!!
