Abstract: A system for controlling a plurality of power consuming devices is disclosed including a plurality of nodes, a gateway that communicates with the plurality of nodes, and a controller configured to send command signals to the nodes via the gateway. The controller associates each node with a region, each region representing a physical area and having a target profile associated therewith. The controller includes a command signal generation unit that determines command signals for a node based on the associated target profile, each node providing control signals to a corresponding power consuming device in response to a command signal received from the controller.

Abstract: A method of estimating light intensity at a target location remote from a light sensor by providing a light sensor at a measuring location and temporarily providing a light sensor at a remote target location; exposing the measuring and target locations to a rand light intensities; constructing a calibration relationship between measured light intensity at the measuring and target location; and subsequently measuring light intensity at the measuring location; and using the calibration relationship to estimate light intensity at the target location. Lighting systems employing such a method are also provided.
