1. A lighting control system, comprising:
- a plurality of lamps interconnected within a residence by a wireless mesh network, wherein a group of lamps within the plurality of lamps each comprise a unique address and a group address that is dependent on where within a residence the group of lamps reside;
a control device wirelessly coupled to the group of lamps and comprising a data file that associates the unique address with the group address;
a button configured on the control device that, when actuated, is configured to send a groupcast control message to only the group of lamps having their unique address associated with a unique group address; and
a receiver on the control device for receiving a unicast acknowledge message from each of the group of lamps that receive the groupcast control message, wherein the unicast acknowledge message is sent through a single, first lamp-to-lamp path across the wireless mesh network based on routing tables stored within each of the plurality of lamps.

Abstract
A lighting control system and method is disclosed for not only controlling visual content loaded within a group set of illumination devices configured within a wireless network, but also for ensuring minimal control delay to those grouped devices. The lighting control system can include a lighting controller device that controls a plurality of lamps within a mesh network, not only to group those lamps but also to assign content to lamps within that group. The combination of a guaranteed groupcast to each of the group of lamps and an acknowledge back from those lamps that is aggregated over a single path achieves the improved lighting control system disclosed herein.

6. A method for controlling a plurality of lamps within a wireless network, comprising:
-
assigning a unique address to each of the plurality of lamps; associating the unique address with a group address for a grouped subset of the plurality of lamps; sending a groupcast control message to only the grouped subset of the plurality of lamps having the group address; and returning a unicast acknowledge message as a single message having aggregated unique addresses of the grouped subset of the plurality of lamps that received the groupcast control message, wherein the unicast acknowledge message is returned from each of the grouped subset of the plurality of lamps through the wireless network from lamp-to-lamp based on routing tables stored within each of the plurality of lamps. - View Dependent Claims (7, 8)
