I have a second outdoor light that is controlled by 2 MS16A's. The light is on a WS467. The motion sensors are on a different HU code, but they could be set to the same. I use a script to turn the lights on/off and use the motion sensor input as the trigger for the script to know when motion is sensed. These work ok, but I find the range/view angle limited, the detect a bit slow, and the weatherproofing moderate at best, and the transmission range terrible. If they meet your needs (range/view angle/environment/transmission range), then that is another option. But, as dave w pointed out, it does require a transceiver and that module must be within ~20ft if everything is stock.
