Lots of us have smart phones in our pocket, why not use the power of the phone to control things around us. Troy Collinsworth uses his to control his garage door, start his car and turn on the sprinkler system. This is all done using bluetooth. This Daisy Works board and this Android software if the heart of what makes the system tick. The outputs of the board are used to simulate button presses.
Thanks for the tip John.
