This causes the hawkeye to send the ON command when the relay turns on. I use this to turn on a room air conditioner when the temperature gets too high. Then send the OFF when the relay opens signaling the correct temperature. My wife and I are both new to the whole garage parking scene. I was going to buy a StopLight, but I had all this spare X-10 equipment lying around, so I figured out how to use it.
Setup is for a two-car garage.
First, put the lights all on socket rockets, programmed to the same code. Park the cars in the garage. Plug in your transceiver module, set to the proper house code. Set your two motion detectors to the same house code and unit code as the lights. Now, on each wall beside the car, mount your motion detector at the same height and location as the front bumper.
