Abstract: It is an object of the present invention to provide an apparatus that allows for improving the self-healing capability of a network, wherein the apparatus is adapted to be part of a network (100), like a ZigBee network. The operation apparatus (110) is adapted to operate a network device (101) and comprises a network information providing unit (111), wherein the network information refers to information with respect to maintenance messages (105, 106, 107) sent and/or received by a network device (101) and/or a neighboring network device (103, 104) to maintain the network, a determination unit (112) for determining self-related connection information from the network information, wherein the self-related connection information refers to information on the connection of the network device itself with the network, and a control unit (113) for controlling the network device based on the self-related connection information.

Abstract: The invention refers to providing a control module allowing to reduce computational efforts for providing a luminaire with a tunable color temperature. The luminaire (100) comprises two light sources (112, 111), for instance, LEDs, wherein each light source generates white light at a different CCT. The control module comprises a color temperature providing unit (121) providing a desired color temperature, and an assignment providing unit (122) providing an assignment list comprising assignments, wherein each assignment comprises a predefined CCT to which brightness values for each light source are assigned. A brightness value determination unit (123) determines brightness values for the light sources based on the desired color temperature and the assignment list, and a control unit (124) controls the luminaire based on the determined brightness values. The control module allows to reduce the constructional and computational efforts for providing a color temperature tunable luminaire.
