Load Control Device with Two-Way Communication Capabilities
First Claim
1. A load control device, comprising:
- a load controller operable to control electrical power to a device;
a power line carrier transmitter, logically coupled to the load controller, that transmits information to a remote device by coupling a first power line carrier signal to a power distribution line, the first power line carrier signal comprising the information.

Abstract
A load control device having two-way communication capabilities. The load control device can include a conventional load control receiver that receives information, such as load control commands or requests. The load control receiver can include a receiver operable to receive power line carrier signals via a power distribution line. The load control device can further include a power line carrier signal transmitter that couples a power line carrier signal onto the distribution line. The power line carrier signal transmitter can communicate information associated with the load control device and information associated with one or more electrical devices that are controlled by the load control device to a remote device. The information may be transmitted from the load control device to the remote device in response to a request received by the load control device or on a periodic basis.

22. A load control device, comprising:
-
a load controller operable to control power supplied to an electrical device from a power distribution system in response to a command; a power line carrier receiver logically coupled to the load controller and operable to receive a first power line carrier signal transmitted along a power line of the power distribution system, the first power line carrier signal comprising the command; and a power line carrier transmitter logically coupled to the load controller and operable to transmit information to the remote device by causing a second power line carrier signal to propagate along the power line to the remote device, the second power line carrier signal comprising the information. - View Dependent Claims (23, 24, 25)
