Bind Motion Sensor But Don't get value when it changes.

Hi,

I'm implementing this motion sensor.

Has IAS_ZONE cluster on the first ep.

I'm focusing on the second ep that has Occupancy Cluster.

I've bind the value, set delay between unoccupied and occupied to zero seconds , and viceversa.

But when i move infront of it to raise the occupancy i don't get any value reported. any idea?
