This invention discloses a commissioning method that makes use of one or more neighboring relationship established among the plurality of nodes to derive a proper role for an individual node, and then to configure the individual node to operate according to the role assigned. The disclosed commissioning method may be carried out semi-automatically or automatically.

Using this temporary gateway (50), (part of) the data can be routed 5 directly to/from the destination/source nodes (10, 40) thus freeing up capacity in the remainder of the network.

Abstract: A method and apparatus for controlling lighting settings in a lighting system in which a memory stores a previous lighting setting. A change of light settings, caused by a trigger event can be reversed, to return to the setting stored in memory, by a corrective user input, providing an undo function. The initial change caused by a trigger event may be an automated change without user input, in response to information provided by a sensor, such as a motion sensor or ambient light sensor, or by a clock for example. The time period between the change of lighting settings and the corrective input may be determined, and restoring the first light setting may be dependent on said corrective input being received within a set time period from the change from the first light setting to the second light setting.
