The remote control device may provide feedback via the status indicator that indicates the present intensity level of a lighting device responsive to the remote control device. The remote control device may provide feedback to indicate a first present intensity level of a first lighting device when the command is a first command type, and a second present intensity level of a second lighting device when the command is a second command type. When the first command type is a raise command and the second command type is a lower command, the first present intensity level may be less than the second present intensity level. In addition, the first lighting device may be a lighting device responsive to the remote control device with a lowest present intensity level and the second lighting device may be a lighting device responsive to the remote control device with a highest present intensity level.

Controlling groups of electrical loads

A load regulation device for controlling the amount of power delivered to an electrical load may be able to calibrate the magnitude of an output voltage of the load regulation device in order to control the magnitude of a load voltage across the electrical load to a predetermined level. The load regulation device may receive the feedback from a calibration device adapted to be coupled to load wiring near the electrical load. The feedback may indicate when the magnitude of the load voltage across the electrical load has reached a predetermined level. The load regulation device may gradually adjust the magnitude of the output voltage, receive the feedback from the calibration device, and then use the feedback to determine the magnitude of the output voltage corresponding to when the magnitude of the load voltage across the electrical load has reached the predetermined level.

Calibration of a load control device for a light-emitting diode light source

A device may detect a power removal event, determine whether the power removal event is a local power removal event or a system power removal event, and perform state correction. For example, the device may receive an indication of a state change event turning on the lighting device. The indication may be received from a sensor. For example, the sensor may include a photosensing circuit (e.g., capable of detecting light emission from the lighting device) or the sensor may include a live voltage sensor (e.g., capable of detecting a change in current driven to the lighting device). The device may then determine whether the power removal event is a system power removal event or a local power removal event. If the device determines that the power removal event is a system power removal event, the device may perform state correction (e.g., setting the lighting device to its state prior to the power removal event).

State retention load control system

A remote control device for controlling lighting devices may be configured to detect an excessive user interaction (e.g., a continued user interaction) and reduce a number of command messages that are being transmitted to prevent the lighting devices from producing undesirable visual effects. The remote control device may comprise a user interface (e.g., that may include a rotation portion, such as a rotary knob) and a processor configured to receive an indication of a user interaction via the user interface. The processor may periodically transmit command messages at a transmission frequency in response to a continued user interaction, where each of the command messages comprise a respective command for adjusting to a respective lighting level. The processor may also start a usage timer in response to receiving the indication of the user interaction, and decrease the transmission frequency in response to the usage timer exceeding a usage threshold.

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.

Turn-on procedure for a load control system

A load regulation device, such as an LED driver, may be configured to control the intensity of a light source based on an analog control signal and a preconfigured dimming curve. The LED driver may sense a magnitude of the analog control signal and determine a new low-end and/or high-end control signal magnitude that falls outside of the input signal range of the dimming curve. The LED driver may rescale the preconfigured dimming curve according to new low-end and/or high-end control signal magnitudes and dim the light source based on the rescaled dimming curve. Multiple LED drivers controlled by the same analog control signal may communicate with each other regarding the magnitude of the analog control signal sensed by each LED driver, and match their target intensity levels despite sensing different analog control signal. A controller may be provided to coordinate the operation of the multiple LED drivers.

A control device configured for use in a load control system to control an external electrical load may provide simple feedback regarding the operation of the control device. For example, the control device may comprise a base portion configured to be mounted to an electrical wallbox or over a mechanical switch, and a control unit connected to the base portion. The control unit may comprise a rotation portion rotatable with respect to the base portion, an actuation portion, and a light source. The control unit may be configured to control the light source to illuminate at least an illuminated portion of the actuation portion in response to actuations of the rotation portion and the actuation portion. In addition, the control unit may provide a limit indication on the illuminated portion by blinking the illuminated portion when the electrical load has reached a limit.
