My sensor is now installed. Correct installation is key. Try not to implement dead zones in the software. Instead, aim the sensor in such a way that the difficult spots (in my case a window and a ceiling fan) are not in sight of the sensor.
Reason not to use dead zones: if a person enters the dead zone, the presence is not detected anymore. In my case: if i would stand beneath the ceiling fan, i would become undetected.
I installed the sensor high up, in the corner, by using a angle iron (bending it to 45 degrees), taping it in white electrical tape for an incognito look, and using a white tiny cable tray. By putting it high up in the corner, facing the sensor downwards, i get 3 benefits:
-curtains/window is not detected
-ceiling fan is not detected
-perfect vision to the rest of the room
