Control Radio Garage door

Hi,

Ive been digging around how i can control my garage door with the use of a radio signal and smartthings. I open / close the garage door by using a standard garage 863.3MHZ key fob (http://www.ebay.co.uk/itm/868-3MHZ-Copy-Code-Remote-Garage-Door-Cloning-Electronic-Key-Fob-for-Hormann-/351502916954?var=&hash=item51d734dd5a) . Is it possible to to configure smartthings or use a 3rd party device to clone this signal and fire it off, then use the smartthings multi sensor to detect if the door is open or closed ?

Thanks

Anyone has a suggestion here ?

Wire a relay to the fob.
