Abstract: A method for commissioning a lighting control system includes selecting a control device for a lighting group in the lighting control system, and receiving, via the control device for the lighting group, a first instruction to the lighting control system. The first instruction may cause devices in the lighting control system to enter a pairing mode. A first device to be associated with the control device may be selected based on motion of a person in a vicinity of the first device detected by a sensor. The first device may be associated with the lighting group for a specified space based on the motion detected by the sensor. A second instruction may be received via the control device for the lighting group and, in response to the second instruction, the lighting control system may exit the pairing mode.

Abstract: A lighting relay panel may include lower-cost features or components related to improved safety and reliability. In some cases, the relay panel includes a power supply capable of protecting the panel from high-voltage and high-current transients. A microcontroller may determine a power interruption based on a zero-cross signal received from the power supply, and may also configure latching relays during the interruption. In some implementations, the relay panel includes a relay sense circuit that is capable of receiving actuation signals from multiple relays connected to different phases of a power signal, and the microcontroller may synchronize or repeat the actuations based on a signal from the relay sense circuit. The microcontroller may generate relay addresses based on the relay positions within the relay panel. In some cases, the relay panel may include isolation circuits that are capable of providing an isolated control signal having an improved voltage range.

Abstract: A lighting control system allows user control of the color features of controllable light fixtures. Controlled color features may include the color, color temperature, tint, or other qualities related to the color of the light. Control of the color features may be independent from control of the intensity of the light fixtures. The system may use light-emitting diode (LED) light fixtures, or fluorescent or incandescent light fixtures. The system may enable control of the color feature using a controllable driver/ballast and a dimmer control. The color feature may be adjusted along a color path of adjacent values in a suitable color space model.

Abstract: A wall plate and system for covering an electrical component in an electrical box. The wall plate includes a base plate having a central aperture, and two trim pieces that join at the sides of the base plate to complete the wall plate. The base plate may include two side edges and wing portions extending from the side edges, and the trim pieces slide onto the respective side wing portions. The trim pieces may have features to engage a mounting plate attached to the electrical box or the electrical component, to capture the wall plate over the electrical box. A locking mechanism may be provided to lock the trim pieces in their inward positions against the base plate. The wall plate may be attachable without the use of tools or fasteners.
