It is the motion of the shadows that has always killed me. BI isn't smart enough yet to distinguish the shadow motion from the object motion.
Zone crossing triggers have had some success with my scenario. I make the shadow movement be within one zone then they are ignored with triggers only when something crosses out or into that zone.
In 'Motion Sensor', there is an option called 'Cancel Shadows'. It's depreciated, and will be removed at some future point.
I've used it, and it does work... to a point.
What I've done instead, is to use Zone triggering, putting the two zones farther apart, where one, or both) of the zones will not get the shadow movement in them. I connect both zones using a third zone. Works very well.
If you woudl like to further this discussion, please make a separate topic.
