A lighting system includes a plurality of nodes arranged in a serial network. The lighting system has a master node, one or more gateway nodes, a first communication bus connecting the one or more gateway nodes to the master node, a plurality of slave nodes such that each slave node is connected to a lighting source and is arranged for conveying data messages, and one or more second communication buses, each connecting one of the gateway nodes with one or more slave nodes of the plurality. The master node is arranged for conveying a unique network address to the one or more gateway nodes via the first communication bus, and the one or more gateway nodes are arranged for conveying a unique network address to the plurality of slave nodes via one of the second communication buses. At least one gateway node is arranged for storing a lighting plan for lighting one or more slave nodes connected to that gateway node.

A measurement system, its assembly and use are disclose. The system may include an instrument for making sensor measurements. The instrument has a substantially cylindrical housing. The shape and size allow the instrument to easily fit in an average hand enabling handheld operation. The housing houses a board stack of electronic boards. These electronics drive an electrical signal in at least one drive channel and measure responses from at least two sensing channels. These responses are provided to a processor for analysis. The instrument has a sensor connector that enables simultaneous electrical and mechanical attachment of an end effector.

Methods and systems are provided to allow for merchant or third party controlled adjustment of a physical environment around a user. Such adjustments may be in response to user actions and may create a more immersive experience for the user. Such adjustments may be determined from interaction data received from a user device, with may identify a service provider, a product, or an activity that the user is currently engaging in or is interested in. One or more secondary devices may be identified to be within an area around the user device and one or more environmental rules associated with the service provider, product, or activity may be determined and communicated to the one or more secondary devices to cause the one or more secondary devices to adjust a physical environment of the area proximate the user device.

A load control system for controlling at least one electrical load may comprise a plurality of control devices and a sensor external to at least one of the control devices. The sensor may be configured to sense a condition of a space in which the control devices are installed. The at least one electrical load may be controlled in response to the condition sensed by the sensor. The control devices may include respective illuminated portions. The control devices may adjust the intensity of the respective illuminated portions in response to the condition sensed by the sensor. If multiple sensors are included in the load control system to sense the condition, the control devices may adjust the intensity of their respective illuminated portions by aggregating the condition sensed by each sensor.

An automatic driver-dimming-mode detection protocol includes subjecting, via a dimming bus, a luminaire driver to a first driver control signal of test analog voltages. Forcing the luminaire driver, via the first driver control signal, into a power output response that includes: (a) a constant output power mode, or (b) at least two discernable different output power levels. Detecting a dimming mode of the luminaire driver. The step of detecting the dimming mode of the luminaire driver includes: measuring, via a power metering circuit, a power metering measurement corresponding to the power output response; and based on the power metering measurement of the luminaire driver being: (a) the constant output power mode, determining that the luminaire driver is a digital dimming mode type (e.g., DALI), or (b) the at least two discernable different output power levels, determining that the luminaire driver is an analog dimming mode type (e.g., 0-10V).

Feedback is received from a plurality of devices. External data is also received. Statistical patterns of the plurality of devices are determined based on the feedback. A policy is determined based on the statistical patterns, the feedback, and the external data. The policy may include a set of rules dictating the operation of each of the plurality of devices and reducing energy consumption at the plurality of devices. Control data based on the policy is transmitted to the plurality of devices. The control data may be operative to transform the operation of the plurality of devices according to the set of rules.
