That is a great idea for a program. And one I had not really thought about. I was able to create one for myself that is now working. I did go into add a program and created a custom program that sends me a notification (text) 4 min after event (garage door open)
if you close your door when you are there, (as I do) it should only text you when you leave and door is left open. You might be able to even get it only to text when alarm is set, but I did not go that far.
