A system for locating an asset can include a first light fixture disposed in a volume of space and having a first transceiver, a first light source, and a first modulation circuit, where the first light source emits a first light output that defines a first line of sight, where the first modulation circuit generates and sends a first VLC signal that is part of the first light output, where a first light fixture location of the first light fixture in the volume of space is previously determined using the first transceiver during an auto-commissioning process. The system can also include a communication device associated with the asset, where the asset is disposed in the volume of space, where the communication device includes a second transceiver, where the second transceiver receives the first VLC signal from the first transceiver.

Networked intelligent lighting devices may utilize visual light communication to perform autonomous neighbor discovery, for example, as part of a map generation process. Individually, each intelligent lighting device within an installation transmits a series of packets via visual light communication for receipt by one or more of the other intelligent lighting devices. Receiving intelligent lighting devices record the number of received packets from each transmitter. Records of numbers of received packets are conveyed via a data communication network to a centralized process. The centralized process utilizes the conveyed records to determine neighbor relationships between lighting devices, for example to generate a map of devices as located within the installation.

A lighting system utilizes intelligent system elements, such as lighting devices, user interfaces for lighting control or the like and possibly sensors. The system also has a data communication network. Some number of the intelligent lighting system elements, including at least two of the lighting devices, also support wireless communication with other non-lighting-system devices at the premises. Each such element has a communication interface system configured to provide a relatively short range, low power wireless data communication link for use by other non-lighting-system devices at the premises in proximity to the respective intelligent system element. Also, in such an element, the processor is configured to control communications via the communication interface system so as to provide access to the data network and through the data network to the wide area network outside the premises for non-lighting related communications of the other non-lighting-system devices.

Provided is a lighting system that includes a plurality of luminaires, at least one controller in communication with the luminaires via a communication line in a network, and configured to control the luminaires, and a lighting control system including a smart device which wirelessly communicates with the at least one controller and the plurality of the luminaires, and performs a commissioning operation of the luminaires in the network using visual light communication (VLC).

Securing device rejoining for a mesh network of a wireless lighting control system is disclosed. A potential security weakness of a mesh network protocol is that a proprietary link key may be discovered by close, expert examination of a device, potentially facilitating the joining of a rogue device to the network. Requiring subsequent rejoins of any device that had previously joined the network to use a current randomly generated link key, rather than the proprietary link key, prevents rogue devices only having the proprietary link key from joining.

An advanced lighting control system including systems for commissioning a network of lighting fixtures preferably includes a plurality of lighting fixtures, each having a sensor and control module. The sensor and control module includes occupancy and light sensing elements, and a first transceiver. The lighting fixtures can send wireless signals to a second transceiver located in a room controller and/or a network coordinator. The room controller being configured to interpret the occupancy and light sensing information and make decisions thereon, while the network coordinator can rank the lighting fixtures according to a determined signal strength. The network coordinator can command each of the lighting fixtures to illuminate, and based on an observation of the lighting fixture, a determination is made about whether the lighting fixture is located in a particular room. The network coordinator can also include a third transceiver for receiving wireless commands from a remote device.

Methods, apparatuses and systems of a controllable receptacle are disclosed. One apparatus includes at least one switch, wherein the at least one switch connects an input power connection received by the controllable receptacle to a receptacle output when the at least one switch is closed, a motion sensor for sensing motion, a transceiver for communicating with other devices, and a controller. For an embodiment, the controller operative to determine an association of the controllable receptacle with a motion group, wherein the motion group comprises a plurality of devices, wherein the controller communicates with at least one of the plurality of devices, determines that the controllable receptacle is to be activated based on the motion sensor sensing motion or a motion sensor of a device of the motion group sensing motion, and closes the at least one switch when determining the controllable receptacle is to be activated.

An apparatus is provided for creating functional lighting groups. The apparatus includes a multimode wireless switch and a gateway. The multimode wireless switch is coupled to one or more wireless devices via a line voltage, and is configured to enter a grouping mode responsive to commands sent over a wireless network, and is configured to switch the line voltage off and then back on, where the one or more wireless devices send messages over the wireless network indicating that they have been power cycled. The gateway is coupled to the one or more wireless devices over the wireless network, and is configured to send the commands, and is configured to receive the messages and is configured to create a functional lighting group comprising the multimode wireless switch and the one or more wireless devices.

A lighting system (100) and a method of protecting a lighting device of a lighting system against theft are provided. The lighting system comprises a lighting device (110) and at least one other device (170). Both the lighting device and the at least one other device comprises a data storage (116, 176), a controller (114, 174) and a network interface (112, 172). The lighting device additionally comprises a light emitter (118). When the lighting device powers up, the other device transmits a verification value stored in its data storage to lighting device. The lighting device assesses the verification value in relation to a unique value stored in its data storage to check whether the lighting system knows the lighting device. In dependence of the assessment, the lighting device is controlled to operate in a first or in a second operational mode. In a commissioning procedure the other device may receive the verification value for storage in its data storage.
