Abstract: A photocontrol, such as for an outdoor intelligent lighting fixture, may detect levels of ambient light at multiple sections of the photocontrol. The ambient light may be detected via multiple photosensors located at the photocontrol sections. In addition, the ambient light may be detected via multiple color filters (or sections of a color filter) located at the photocontrol sections. The photocontrol may determine an ambient light differential, such as an instant differential between light received at the multiple photocontrol sections at a particular time, or a temporal differential between light received at the multiple photocontrol sections across multiple times. Based on the ambient light differential, the photocontrol may identify triggering photosensor or triggering section that substantially align with a geographical orientation. The photocontrol may identify a lighting output profile. An output level of a lighting element may be modified based on the lighting output profile.

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.

In some implementations, a current indication module may provide an indicator signal based on the load sense voltage. In addition, the indicator signal may be provided to additional components or devices, such as a relay controller configured to activate the latch. In some implementations, the relay controller may be configured to open the latch based on the current level described by the indicator signal.

Abstract: A method for configuring a wireless sensor of a lighting control network may include, providing, by a user, a sensor stimulus to cause the wireless sensor to wake-up from a reduced power operating mode. In the reduced power operating mode, a first radio configured to communicate using a first wireless communication protocol and a second radio configured to communicate using a second wireless communication protocol may be inoperative. The first radio may become operative upon the wake-up. The method may further include receiving, via the first radio, an activation message from a control device. The activation message may cause the wireless sensor to maintain operation of the first radio for a first specified period of time. The method may further include resuming, by the wireless sensor, operation in the reduced power operating mode after the first specified period of time. The wireless sensor may be a battery-powered wireless sensor.
