Les,
I once saw something from a Garage door company that allowed you to use
the cell phone (two buttons) to control the garage door (up or down)
..
Sorry but I didn't read any more about it at the time, didn't have a need..
Might be something worth looking into though..
..
Then there is also that "Arduino" Their UNO (mini computer module)
can be tailored to do a lot of different thing..
It has modules to do a lot of different things...
