Lighting system control via ac power lines

In a lighting system comprising:

• a system controller;
• a power source;
• and
• a gateway coupled to the power source and communicatively coupled between the system controller and a portion of lighting fixtures in the lighting system to be controlled by the gateway, a method of operating the gateway, the method comprising:
• receiving AC power from the power source at a power input port of the gateway;
• filtering electrical noise from the received AC power with a power line filter coupled to the power input port;
• outputting filtered AC power to a power output port of the gateway to power the portion of lighting fixtures;
• receiving a first digital signal at an input signal port of the gateway;
• passing the received first digital signal to an output signal port communicatively coupled to the input signal port at the gateway;
• coupling a second digital signal to the power output port in response to receiving the first digital signal to control the at least one lighting fixture of the portion of lighting fixtures;
• operating a user interface, integrated with the gateway and communicatively coupled to a local controller at the gateway, to configure operation of the gateway with the portion of lighting fixtures;
• and
• operating the user interface to initiate running of at least one program by the local controller,
• wherein the at least one program comprises a test of intensity control and color temperature control of the portion of lighting fixtures.
