Abstract

A lighting control system includes a daylight sensor configured to receive visible light control signals to set or adjust one or more parameters of the daylight sensor including, e.g., a set point (i.e., an acceptable lighting level). The lighting control system also includes a non-transitory computer program product that includes programming instructions that may be downloaded to, e.g., a mobile device and/or may be executed by a processor or like device. The programming instructions may be configured to provide a user interface related to the daylight sensor, receive via the user interface one or more user inputs related to the daylight sensor, and modulate a light output of a light source to transmit visible light control signals corresponding to the received one or more user inputs. Methods of programming a daylight sensor with visible light control signals are also provided, as are other aspects.
