Abstract: An automatic driver-dimming-mode detection protocol includes subjecting, via a dimming bus, a luminaire driver to a first driver control signal of test analog voltages. Forcing the luminaire driver, via the first driver control signal, into a power output response that includes: (a) a constant output power mode, or (b) at least two discernable different output power levels. Detecting a dimming mode of the luminaire driver. The step of detecting the dimming mode of the luminaire driver includes: measuring, via a power metering circuit, a power metering measurement corresponding to the power output response; and based on the power metering measurement of the luminaire driver being: (a) the constant output power mode, determining that the luminaire driver is a digital dimming mode type (e.g., DALI), or (b) the at least two discernable different output power levels, determining that the luminaire driver is an analog dimming mode type (e.g., 0-10V).
