This app works with the hardware device that I developed which allows you to view the status of, and open/close your garage door from anywhere you have Internet access.

Again, the hardware is *required* which you can build yourself - I have full instructions and parts list to build your own, available on my website at http://jamienerd.blogspot.com/2013/12/garage-door-controller-tutorial.html

Permissions:
Internet - this app accesses the Internet in order to connect to your Garage Door Controller device
Access Network State - upon opening the app, it checks to make sure you have network/Internet access
