Abstract: A sensor assembly may be mounted in a ceiling used with an associated light fixture. The sensor assembly may include a body including a sensor end and a blade end opposite the sensor end. A sensor may be disposed on the body nearer the sensor end than the blade end. A cutting blade may be disposed on the body nearer the blade end than the sensor end. The cutting blade may be configured to cut an opening in the ceiling. At least one retainer protrusion may be disposed on the body between the sensor and the cutting blade. The at least one retainer protrusion may be configured to retain the sensor assembly in the opening of the ceiling.

Abstract: An apparatus, and lighting systems and methods are provided for controlling and reporting power usage of an LED driver having an LED load driven by the LED driver. The apparatus is coupled to at least an auxiliary port of the LED driver for monitoring a dimming control voltage associated with the LED driver. The apparatus is configured to estimate the power usage of the LED driver and the LED load based on programmed relationships between the monitored dimming control voltage and a selected dimming profile associated with the LED driver. The dimming profile may either be a selected generic dimming profile for adequate reporting of the power usage or a selected specific dimming profile for increased accuracy of the power usage estimation. The apparatus is further configured to transmit the estimated power usage to an external device for dashboarding and energy savings purposes.

Abstract: Apparatuses, systems, and methods are provided for configuring a device of a lighting control system. The method begins by providing a configuration interface by a centralized controller of the lighting control system. Device configuration information is received via the configuration interface. A communication network of the lighting control system is then placed into a programming mode. A programming request received at the device is detected, and configuration data representing at least a portion of the received device configuration information is transmitted from the centralized controller to the device.
