System and method for control of lighting systems
First Claim
1. A device for controlling lighting systems, the device comprising:
- a processor;
a memory coupled to the processor;
an interface that connects to a power line for transmitting signals over the power line to control one or more light fixturesa network interface for sending and receiving data over a communication network; and
the memory storing instructions that, when executed by the processor, cause the device to perform the operations of;
periodically polling a remote server to obtain demand response information, the remote server being polled over a communication network;
receiving the demand response information from the remote server;
determining, based on the demand response information, to modify light output of the one or more light fixtures; and
transmitting a signal via the power line, the signal including instructions that cause the one or more light fixtures to modify light output.

Abstract
Techniques disclosed herein include systems and methods for automated control of lighting systems. Such lighting system controllers can provide a range of control without requiring substantial programming, and that are compatible with existing, conventional, and new lighting systems. Such controllers include devices that can provide several features including network connectivity, a range of output levels, automated demand response control to manage electricity consumption, automated response to secondary sensor input (such as from photoreceptors and motion detectors), and generation of statistics showing power savings. A lighting controller polls a remote server or associated sensors to gather data relating to light output levels, determines to modify light output of corresponding light fixtures, and then transmits radio frequency signals over electrical power lines to light fixtures to modify light output.

17. A device for controlling lighting systems, the device comprising:
-
a processor; a memory coupled to the processor; an interface that connects to a power line for transmitting signals over the power line to control one or more light fixtures; and the memory storing instructions that, when executed by the processor, cause the device to perform the operations of; periodically polling a sensor to obtain light detection data collected by the sensor from visible light conditions of a physical space corresponding to the one or more light fixtures, and to obtain motion detection data collected by the sensor from the physical space corresponding to the one or more light fixtures; receiving the light detection data from the sensor and receiving the motion detection data from the sensor; determining, based on the light detection data and the motion detection data, to modify light output of the one or more light fixtures; and transmitting a signal via the power line based on the light detection data and the motion detection data, the signal including instructions that cause the one or more light fixtures to modify light output. - View Dependent Claims (18, 19)

20. A computer-implemented method for controlling lighting systems, the computer-implemented method comprising:
-
periodically polling a remote server to obtain demand response information that corresponds to electricity supply conditions, the remote server being polled over a communication network; receiving the demand response information from the remote server at a device that controls a lighting system, the device including an interface that connects to a power line for transmitting signals over the power line to control one or more light fixtures; determining, based on the demand response information, to modify light output of the one or more light fixtures; and transmitting a signal via the power line, the signal including instructions that cause the one or more light fixtures to modify light output.
