Abstract: A lighting control system is provided to reduce the time, cost, and potential for error during device commissioning. A controller is programmed to obtain voice commands from a user and to identify and implement device commissioning modes based at least on the obtained voice commands. In a first commissioning mode, the controller configures one or more buttons or equivalent actuators on a control switch mounted in association with a lighting zone. In a second commissioning mode, the controller assigns device grouping and/or configuration data for a plurality of lighting devices (e.g., lighting fixtures, occupancy sensors, light sensors) in operable connection with the control switch. The controller may further in another commissioning mode identify one or more second lighting devices added to or exchanged with one or more of the plurality of first lighting devices and assign device grouping and/or configuration data thereto.
