if I am on my motorcycle and come home, I want the door to open automatically (if the radius is possible).
I see where you are going with this, a Bat Cave Garage Door. ;-) It certainly is possible. Anything that will try to automatically connect to your main controler via WiFi or blutooth (with proper security signature) will do to alert it.
About the open/close state of the door, maybe your system already has a light that you could use. If not, the simplest and cheapest way is to use a magnet switch (magnet on the door + glass fuse-like switch on the door frame).
