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 independent units responsive to a broadcast controller. Each independent unit includes at least one commander and at least one energy controller for controlling at least one of the electrical loads in response to a control signal received from the commander. The independent units are configured and operate independent of each other. The broadcast controller transmits wireless signals to the energy controllers of the independent units. The energy controllers do not respond to control signals received from the commanders of other independent units, but the energy controllers of both independent units respond to the wireless signals transmitted by broadcast controller. The energy controller may operate in different operating modes in response to the wireless signals transmitted by the broadcast controller.

A load control device for controlling the amount of power delivered to an electrical load may include a rectifier circuit configured to receive a phase-control voltage and produce a rectified voltage. A power converter may be configured to receive the rectified voltage at an input and generate a bus voltage. An input capacitor may be coupled across the input of the power converter. The input capacitor may be adapted to charge when the magnitude of the phase control voltage is approximately zero volts. The power converter may be configured to operate in a boost mode, such that the magnitude of the bus voltage is greater than a peak magnitude of the input voltage. The power converter may be configured to operate in a buck mode to charge the input capacitor from the bus voltage when the magnitude of the phase-control voltage is approximately zero volts.

A state change device may be electrically connected to a switched receptacle, or to both the switched and unswitched receptacles, of an outlet. The state change device may generate a change of state signal when power is applied to, or removed from, the switched receptacle. The state change device may wirelessly communicate the signal. The state change device may include a load control circuit that may be configured to control the amount of power delivered to an electrical load that is electrically connected to the state change device. The state change device may receive commands directed to the load control circuit. The state change device may be deployed in a load control system and may operate as a control entity, such that the state change device may issue commands to one or more load control devices, responsive to the application or removal of power at the switched receptacle.

A power switch configured for use in a multi-way switch system is provided. The power switch includes one or more switching elements configured to selectively couple a load to a power source. The power switch includes a power metering circuit and a communications circuit. The communications circuit can be configured to provide communications between the power switch and at least one other power switch in the switch system. The power switch can include a control device configured obtain data from the power metering circuit. The data can be indicative of power consumption of the load. The control device can be further configured to determine whether the power switch is a master power switch in the multi-way switch system based on the data.

A cloud connected lighting system may include a wireless lighting network of coordinated lighting devices and a bridge to provide connectivity to external devices such as a cell phone, home automation system or security system. The cloud connected lighting system may be implemented locally with a cell phone communicating with the bridge for control, status and alerts. The cloud connected lighting system may operate over the cloud via an Internet connection allowing the bridge to communicate with a server on the Internet that may implement software for the interface with the wireless lighting network and to capture data regarding activity detected by motion sensor associated with the wireless lighting network.

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.

There are provided systems, apparatuses, and methods for controlling power delivery from an auxiliary power supply. For example, there is provided a method that includes generating a first random number to define a timeout period. During the timeout period, the method may detect whether a voltage is present at an output of an auxiliary power supply, may disable the auxiliary power supply when the voltage is detected at the output, and may enable the auxiliary power supply when the voltage is not detected at the output.

A load control device may be used to control and deliver power to an electrical load. The load control device may comprise a control circuit for controlling the power delivered to the electrical load. The load control device may comprise multiple actuators, where each of the actuators is connected between a terminal of the control circuit and a current regulating device. The number of the actuators may be greater than the number of the terminals. The control circuit may measure signals at the terminals and determine a state configuration for the actuators based on the measured signals. The control circuit may compare the state configuration to a predetermined dataset to detect a ghosting condition.
