28. Apparatus comprising:
a circuit that is configured to:
receive electrical power;
provide lighting power from the electrical power, along a first electrical power transmission line, to a light-emitting diode (“LED”) light fixture; and
transmit along the first electrical power transmission line:
first lighting control information that is configured to control light emitted from the fixture; and
second lighting control information that is defined by a pattern in the lighting power;
a first microcontroller; and
a power line communication module;
wherein:
the first microcontroller is configured to provide to the power line communication module the first lighting control information; and
the power line communication module is configured to provide the first lighting control information to the first electrical power transmission line;
the first microcontroller is configured to:
transmit, via the power line communication module, a first discovery-pending message;
wait a predetermined time;
if the first microcontroller:
receives a second discovery pending message from a second microcontroller via a second power transmission line; and
determines that the second microcontroller has a higher priority than the first microcontroller,
terminate a discovery process; and
if the first microcontroller:
receives a second discovery pending message from a second microcontroller via a second power transmission line; and
determines that the second microcontroller has a lower priority than the first microcontroller,
send a discovery-initiated message, via the power line communication module, over the first electrical power transmission line.
