Ok, you guys... what is it that actually is starting the garage opener? Mine works either with a radio signal from it's own activators or by pressing a button switch next to the door from the garage into the house. What signal (radio, closed switch, etc..) are you sending it from what X10 device? Will ANY garage door opener work or does it take a special type. I too have accidently left the door open and would like my smart house to be smarter than me.
