Wireless network control for building lighting system
First Claim
1. A wireless relay controller configured for connection between a power source and a light source, comprising:
- a power supply circuit configured to draw current from the lighting circuit of the power source;
an on/off control circuit configured to switch on or off power to the light source;
a power sensor configured to monitor the energy use of the light source controlled by the wireless relay controller; and
a control signal circuit configured to wirelessly receive control signals to control the operation of the light source.

Abstract
Wireless control of lighting fixtures via a wireless radio network using a radio-controlled relay device located between a lighting fixture or a ballast of a fluorescent fixture and its power supply. The radio-controlled device receives signals from remote controllers or via a computer interface. The wireless device is also configured to monitor the power consumption of a lighting fixture (or ballast) and send that information to the network. In the wireless control network, light level sensors and motion sensors also send information to the network to allow lights to respond to daylight levels or occupancy.
