Fibaro motion sensor reaction time

Hi

I have the fibaro motion sensor that has no Neighbors in the variables table. I am using it to turn my bathroom lights on/off so i need i to respond fast.
As the motion sensor is a battery operated device I know it can not relay signals to other devices, but should it not still have Neighbors in the variable table?

Sometimes it is not reacting at all and some times is reacts to slow. I have tried moving the motion sensor closer to the vera plus controller and that improves reaction time.
