I have a Hawkeye in my bathroom that turns on a nightlight when it is dark and senses motion. It works everytime!? I AM using a amplified coupler so this may be the kicker to my sucess, who knows? My RF receiver is located about 20 feet away from the motion sensor. The motion sensor is located about knee level on the window seal pointing through the bathroom into the bedroom. Once I approach the bathroom it turns on everytime. Sometimes it is delayed a second or so, but it has never not activated. I also have a hawkeye located by the front door and have had 100% success with it.

I'd try to relocate the RF receiver and maybe try a new set of batteries. Anyway, hope you can get as good of results as I have had.
