Claim 20:
21. A non-transitory, machine-readable, storage device that includes instruction that, when executed by control circuitry included in a wallbox-mountable electrical load control device, causes the control circuitry to:
receive a sensor signal from communicatively coupled sensor circuitry;
retrieve, from communicatively coupled memory circuitry, data representative of an active button parameter based on the at least one sensed environmental parameter;
retrieve, from the memory circuitry data representative of an inactive button parameter based on the at least one sensed environmental parameter;
cause a first backlight circuit that includes one or more light-emitting diodes (LEDs) to illuminate an active button using the retrieved active button backlight intensity responsive to an actuation of the active button; and
cause a second backlight circuit that includes one or more LEDs to illuminate at least one inactive button using the retrieved inactive button backlight intensity responsive to the actuation of the active button.
