Aeon MultiSensor 4 in 1

I have a Aeon MultiSensor and for some reason I keep on having communication errors showing up in my vera, I have a scene setup to turn my patio light on using the Aeon MultiSensor as a trigger but there is no communication with my vera lite. I have multiple hardwired zwave device near by to relay commutation and like i saif there is time it will work fine for instance it will trigger my light on but 5 minutes later if some one walks by again it wont trigger my light back on, I see the red led come on the Aeon MultiSensor but nothing happens. Is there any setting that might need to be changed in the settings or is there a better motion senor that i should get to make this work permanently?
