Load-sensing remote control device for use in a load control system
First Claim
1. A load control system comprising:
- a remote control device configured to be clamped around at least one electrical conductor of an AC power cord of an electrical load, the remote control device comprising;
a control circuit;
a sensing circuit communicatively coupled to the control circuit and configured to sense an electrical current of the electrical load, the sensed electrical current indicating a change in state of the electrical load from an on state to an off state;
a programming button communicatively coupled to the control circuit, wherein in response to the programming button being actuated, the control circuit is configured to associate the remote control device with a load control device so that the load control device is responsive to messages transmitted by the remote control device, wherein the load control device is configured to control an intensity of a lighting load by controlling an amount of power delivered to the lighting load, and wherein the lighting load and the electrical load are different loads; and
a communication circuit communicatively coupled to the control circuit and configured to transmit messages to the associated load control device;
wherein in response to sensing, via the sensing circuit, the change in the state of the electrical load from the on state to the off state, the control circuit is configured to transmit a message to the load control device via the communication circuit, wherein the transmitted message includes information related to the change in the state of the electrical load from the on state to the off state, and wherein the transmitted message causes the load control device, in response to receiving the transmitted message, to control the amount of power that is delivered to the lighting load to blink the lighting load by increasing and decreasing the intensity of the lighting load.

Abstract
A load control system, such as a lighting control system, may be configured to control a first electrical load in response to a sensed operational characteristic of a second electrical load. The load control system may include a load control device electrically connected to the first electrical load, and a load-sensing remote control device that is configured to sense an operational characteristic of the second electrical load. The load-sensing remote control device may be configured to communicate with the load control device via wireless communication. The load-sensing remote control device may be configured to transmit messages to the load control device in response to sensing a change in the operational characteristic of the second electrical load. The load control device may be configured to, upon receiving messages from the load-sensing remote control device, control an amount of power that is delivered to the first electrical load.
