Control of network lighting systems

A luminary for a networked lighting system comprising:

• a receiver for receiving a multicast message from a lighting controller of the networked lighting system, wherein the multicast message comprises a luminary related information field identifying several selected luminaries and a features field identifying a predetermined function, wherein the predetermined function includes input values corresponding to location information for each luminaire of a plurality of selected luminaries and said input values corresponding to contextual information, the contextual information including a room temperature and a time value associated with each luminaire of the plurality of selected luminaries for each luminaire of the plurality of selected luminaries to adapt light settings using the predetermined function, and generate as output values, individual, differentiated control information for each luminaire of the plurality of selected luminaries, wherein the output values for the luminary are different from at least one other luminary of the plurality of selected luminaries using the same predetermined function and based at least in part on a difference in location information between the luminary and the at least one other luminary of the plurality of selected luminaries;
• and
• a controller being configured to execute the predetermined function using the features field of the multicast message and the luminary related information field of the multicast message to calculate the individual, differentiated control information for the luminary, the controller being further configured to set a lighting configuration created for the luminary in accordance to the luminary control information, wherein the lighting configuration created for the luminary is different from lighting configuration for the least one other luminary of the plurality of selected luminaries.
