Abstract

The present disclosure generally pertains to lighting control systems and methods. In one exemplary embodiment, a building having at least one light source controlled by a manually-actuated switch is retrofitted with a networked control system. In this regard, the manually-actuated switch is decoupled from a power line that provides power to the light source, and the power line is coupled to a node of a wireless network to provide in-line control of the light source. Another node of the network is coupled to the manually-actuated switch so that the node can receive inputs from such switch. Such node uses the wireless network to transmit data indicative of the inputs from the manually-actuated switch. Logic then uses such data to control the activation state of the light source via the in-line relay coupled to the power line.
