Abstract: The invention relates to a controlled device (1, 1?), a system (25, 25?) comprising such controlled device (1, 1?) and a controller device (21), a method for setting up such controlled device (1, 1?) and a software product for a set up processor (3, 3?) of such controlled device (1, 1?). In order to allow the controlled device (1, 1?) to persistently stay within the framework of the system (25, 25?) over its power cycles while avoiding or at least reducing a need for a costly element like a NVRAM on the side of the controlled device (1, 1?). Rather than providing costly NVRAM in the controlled device (1, 1?), the controlled device (1,1?) is just provided with fixed information which allows the controlled device (1,1?) to receive or obtain the variable control data from the controller device (21) as an outside source.

Abstract: A lighting system controller, a lighting system control method and software program product are provided for controlling a lighting device based on a trigger signal, such as a presence detection signal from a presence sensor. Instead of switching the lighting device to a fixed light setting at all times when the trigger signal is received, the initial light output of the lighting device is determined. The lighting device is then controlled according to a fixed light setting (e.g. white light at full brightness) if the determined initial light output is within a predetermined range, and else it is controlled according to a function relative to the determined initial light output. For example, if the lighting device is participating in a romantic scene emitting predominantly red light the lighting device may switch to reddish white light instead of the full white light and/or the brightness level of the light is lowered compared to the fixed light setting.

Abstract: A two-wire lighting system comprising a lighting device connected to a first wire, and a light switch connected to a second wire, and a connecting wire connecting the light switch to the lighting device. The first and second wires are connected across a mains system. The lighting device comprises a lighting controller and a bleeder controllable by the lighting controller. The light switch comprises a wireless transmitter, a switch controller and a mechanical switch connected to the switch controller. The switch controller is configured, in response to actuation of the mechanical switch by a user, to generate a bleeder activation signal in the connecting wire. The lighting controller is configured to activate the bleeder according to the bleeder activation signal so as to induce an operational current in the wires. The switch controller is configured to use the operational current to transmit a message from the wireless transmitter.

Abstract: In a wireless mesh network, a battery operated node can select a parent node via which messages are routed to further nodes. The parent node can initially be selected based on signal strength. The node receives acknowledgements for messages sent, if they arrive. The node calculates a reliability indicator of the parent node based on the number of messages for which an acknowledgement has been received. If the reliability indicator exceeds a predetermined threshold the node selects a new parent node, based on second selection criteria. For example, the node with the next greatest signal strength.

Abstract: A configuration system (100) for configuring a first device (130) in a lighting system is disclosed. The configuration system (100) comprises a memory (102) arranged for storing one or more light settings (110), which light settings (110) are defined by one or more light setting rules (112). The configuration system (100) further comprises a communication unit (104) arranged for communicating with the first device (130). The configuration system (100) further comprises a processor (106) arranged for identifying a device property (132) of the first device (130) based on information received from the first device (130) via the communication unit (104).

Abstract: A method, device and computer program product for (near) synchronous control of networked lighting devices is presented. In networked lighting systems, a control command sent to the networked lighting devices is limited in length and as such it is not always possible to include the identifiers of the networked lighting devices, as well as the color point and/or intensity level they should change to in a single control command. However, sending multiple control commands in sequence can result in the undesired effect that these lighting devices change light output out-of-sync. The invention proposes to determine an approximate color point and/or approximate intensity level in, respectively, a color space and/or intensity space of a lower resolution. This allows a control command to comprise the identifiers of the networked lighting devices, as well as the approximate color point and/or approximate intensity level for (near) synchronous control of the networked lighting devices.
