Apologies for the delay -- for some reason my forum messages were routed to spam.
My suggestion is to associate the occupancy sensor with the space that it monitors which is also fed by the luminaire w/ the on-off status:
:luminaire a brick:Luminaire ;
brick:hasPoint :on-off-status ;
brick:feeds :lighting-zone .
:lighting-zone a brick:Lighting_Zone ;
brick:hasPart :room1 .
:room1 a brick:Room ;
brick:hasPoint :occupancy-sensor .
:occupancy-sensor a brick:Occupancy_Sensor .
:on-off-status a brick:On_Off_Status
Does that solve your problem?
