Sensor lighting control systems and methods

摘要

A sensor lighting control system automatically controls lighting on a home automation network without creating unnecessary network traffic. A sensor module uses the light level to determine when a command to turn the light ON should be resent over the network.

1. A method to automatically control lighting on a home-control network, the method comprising:
automatically transmitting over a home-control network a lighting control command from a sensor module to control a state of a light, the home-control network configured to propagate the lighting control command using powerline signaling and radio frequency (RF) signaling, the lighting control command being one of an ON command and an OFF command; detecting motion and ambient light with the sensor module; transmitting the ON command through the home-control network and starting a timer having a timer count in response to detected motion when the ambient light is less than a threshold; determining whether the light is OFF, the light being further controlled independently of the sensor module by a switch configured to send the lighting control commands over the home-control network in response to a physical input by a user; and setting the timer count to an end count when the light is OFF in response to the physical input by the user.
