Abstract
Disclosed are methods and apparatus for lighting control based on a combination of inputs. Local inputs indicative of light levels, occupancy statuses, and environmental conditions near lighting fixtures are received, and group inputs to control the dimming state of lighting fixtures are also received. The group inputs may utilize manipulation of mains power powering lighting fixtures to indicate a dimming level. The dimming states of light sources of lighting fixtures are based on group inputs and local inputs.
