Larry, thanks for the wiring diagram, however I cannot show it here because it is incorrect, unless the power starts at the light, and it does not appear that way. To make this work you would need an additional cable run between the power source and the switch box where the cable leads to the light fixture.  Please see the 4-way switch wiring diagrams and instruction using the links below.

    Hi Dave, no I have not seen a 4-way motion switch or occupancy sensor switch, however you can wire one of these up yourself if you are an experienced electrician. See this article: Multiple Motion Detectors for Light Switches
