Present invention is a system for which multiple DALI streams could be addressed over one DALI interface on a single wireless communication protocol (e.g., ZigBee) personal area network (PAN). Allowing multiple DALI streams to be controlled over a single ZigBee PAN reduces complexity, costs, and allows for more efficient utilization of bandwidth greatly increasing effective DALI bandwidth supported by a single wireless gateway. This enables multiple physical DALI Controllers to be attached, and also allows DALI Controllers which are unable to support the special DALI stream selection command to communicate with multiple streams on a single ZigBee PAN. Due to the diverse nature of DALI Controllers and control devices, having an interoperable approach is critical. This system allows for a baseline set of capabilities with DALI devices that do not support the additional reserved DALI commands and a set of advanced capabilities for devices that do.
