FYI, most security systems can integrate this feature for not much. I have the same problem, and I've had powered garage doors for most of my life. I never use my front door, I always come in and out of my garage, and in the morning when I'm on the way to work I always used to have to do a second pass around the neighborhood to make sure my garage door is closed. I've got ASG security systems at my house and shop, and I can monitor everything, control my garage door, control the AC at my house, etc etc etc. Luckily those systems were installed both in my house when I bought it and in the shop when I moved in, so I didn't have to pay anything to have it all installed, just had to have it activated and it costs me like $70 a month for both (or something around that).
Also, FWIW, there IS a note on my dash that says 'close garage door'. I read it just as I'm pulling out of the neighborhood.
