Abstract: A control device may be configured to transmit messages using an adaptive transmit power. The control device may determine a transmit power for transmitting the message based on a command in the message. The control device may determine a transmit power based on a change in lighting intensity caused by the command. The transmit power may be greater when the change in lighting intensity is above a threshold than when the change in light intensity is below the threshold. The control device may determine whether the message was successfully received based on the receipt of an acknowledgement message. The control device may increase the transmit power when the message fails to be received and retransmit the message including the command at an increased transmit power. The control device may store (e.g., learn) the increased transmit power for later use.

Abstract: A load control device for controlling power delivered from an alternating-current power source to an electrical load may comprise a controllably conductive device, a control circuit, and an overcurrent protection circuit that is configured to be disabled when the controllably conductive device is non-conductive. The control circuit may be configured to control the controllably conductive device to be non-conductive at the beginning of each half-cycle of the AC power source and to render the controllably conductive device conductive at a firing time during each half-cycle (e.g., using a forward phase-control dimming technique). The overcurrent protection circuit may be configured to render the controllably conductive device non-conductive in the event of an overcurrent condition in the controllably conductive device. The overcurrent protection circuit may be disabled when the controllably conductive device is non-conductive and enabled after the firing time when the controllably conductive device is rendered conductive during each half-cycle.

Abstract: A load regulation device is adapted to control an electrical load. The load regulation device may be in a low power state, a ready state, and/or an on state. The low power state is characterized by the electrical load being unenergized. The ready state is characterized by a load control device and/or the load regulation device using more power than the low power state and the electrical load being unenergized. The on state is characterized by the electrical load being energized. The load regulation device is configured to receive an indication of a user's presence when the load regulation device is in the low power state. The load regulation device is configured to change from the low power state to the ready state in response to receiving the indication. The load regulation device is configured to wait in the ready state for a change state instruction.

Abstract: A load control system may include control devices for controlling power provided to an electrical load. The control devices may include a control-source device and a control-target device. The control-target device may control the power provided to the electrical load based on digital messages received from the control-source device. The control devices may include a load control discovery device capable of sending discovery messages configured to discover control devices within a location. The discovered control devices may be organized by signal strength and may be provided to a network device to enable association of the discovered control devices within a location. The discovery messages may be transmitted within an established discovery range. The discovery range may be adjusted to discover different control devices. Different control devices may be identified as the load control discovery device for discovering different control devices.

Abstract: A control device, such as a gateway device for a wireless load control system, has a light bar extending around a periphery of an enclosure to provide feedback to a user of the load control system, as well as to provide a pleasing aesthetic effect on the gateway device. The control device may include at least one light-emitting diode mounted to a printed circuit board inside the enclosure, a control circuit mounted to the printed circuit board and operatively coupled to the light-emitting diode for controllably illuminating the light-emitting diode, and a multi-functional mounting structure for mounting the printed circuit board inside the enclosure. The mounting structure may have at least one light-pipe structure for conducting light from the at least one light-emitting diode to the light bar. The mounting structure may have an antenna-mounting structure to which an antenna of the control device may be mounted.

Abstract: A load control system for a building having a lighting load, a window, and a heating and cooling system comprises a lighting control device, a daylight control device, and a temperature control device operable to be controlled so as to decrease a total power consumption of the load control system in an energy-savings mode. The energy-savings mode can be manually overridden in response to actuation of the actuator of an input control device, such that the load control system enters a manual mode for manually adjusting the loads controlled by the lighting control device, the daylight control device, and the temperature control device. The load control system is operable to automatically return to the energy-savings mode at a time after the load control system entered the manual mode.

Abstract: A load control device for controlling power delivered from an AC power source to an electrical device may be configured to conduct current through earth ground and may disconnect a switching circuit to reduce an amount of current conducted through the earth ground. The load control device may comprise a controllably conductive device configured to control the power delivered from the AC power source to the electrical device so as to generate a switched-hot voltage, a switching circuit electrically coupled with a detect circuit, and a control circuit configured to render the switching circuit conductive and nonconductive. The detect circuit may generate a detect signal indicating a magnitude of the switched-hot voltage. The control circuit may be configured to monitor the detect signal and to render the switching circuit non-conductive after detecting an edge on the detect signal to reduce the total current through the earth ground.

Abstract: A load control system for controlling the amount of power delivered from an AC power source to a plurality of electrical load includes a plurality of energy controllers. Each energy controller is operable to control at least one of the electrical loads. The load control system also includes a first broadcast controller that has a first antenna and a second antenna. The first antenna is arranged in a first position and the second antenna is arranged in a second position that is orthogonal to the first position. The broadcast controller is operable to transmit a first wireless signal via the first antenna and a second wireless signal via the second antenna. Each of the energy controllers is operable to receive at least one of the first and second wireless signals, and to control the respective load in response to the received wireless signal.
