Abstract

Networked intelligent lighting devices and other elements connected to the network of a lighting system are readily adaptable to desirable networking arrangements as well as logical functional groups, for example by each storing communication provisioning data and/or configuration data for logically associating system elements into one or more groupings or sub-networks. The exemplary systems and system elements may also enable such enhanced network arrangement via autonomous discovery and device commissioning.
