Method for the operation of a network of lights, including the steps of: providing multiple control modules (1, 2, 23, 23', 28, 28'), allocating each control module to a light of said network of lights, each control module comprising: - one long-distance communication module, - one short-distance communication module, - preferably a near field communication module, - a geocoordinate module, - a controller, - preferably at least one sensor, - a control output for controlling a driver of the light, providing a server reachable via the long-distance communication module of each control module, dividing the multiple control modules (1,2,23,23',28,28') into one or more control module groups (A,B) based on environmental, light and/or control module information provided by the control modules (1,2,23,23',28,28') for operation of the network based on the information provided by the control modules (1,2,23,23',28,28'), selecting, by the server, one of the control modules (1,2,23,23',28,28') of each group (A,B) as a group controller (2,23',28'), with which all other control modules (1,23,28) of the respective group (A,B) can communicate via their short-distance communication modules, forming by the control modules (1,2,23,23',28,28') within each group a short-distance network via their corresponding short-distance communication modules, preferably a mesh network, determining, by the server, a new group controller of a group of said one or more control module groups in case of failure of the group controller of said respective group, and announcing said new group controller within said group on the level of the short-distance network, thereafter the other control modules of said group not defined as group controllers establishing their connections via the new group controller, and, during normal network operation, only by the group controller (2, 23, 23') of each respective group, transmitting to the server its own environmental, light and/or control module information and the corresponding information received from other control modules (1, 23, 28) of the respective group via the short-distance communication modules of the other control modules of the respective group; wherein said normal network operation is understood as the usual operation of the network, in which each control module of the network is allocated to a group and in which all control modules carry out their actual task, controlling the light. providing multiple control modules (1, 2, 23, 23', 28, 28'), allocating each control module to a light of said network of lights, each control module comprising: - one long-distance communication module, - one short-distance communication module, - preferably a near field communication module, - a geocoordinate module, - a controller, - preferably at least one sensor, - a control output for controlling a driver of the light, - one long-distance communication module, - one short-distance communication module, - preferably a near field communication module, - a geocoordinate module, - a controller, - preferably at least one sensor, - a control output for controlling a driver of the light, providing a server reachable via the long-distance communication module of each control module, dividing the multiple control modules (1,2,23,23',28,28') into one or more control module groups (A,B) based on environmental, light and/or control module information provided by the control modules (1,2,23,23',28,28') for operation of the network based on the information provided by the control modules (1,2,23,23',28,28'), selecting, by the server, one of the control modules (1,2,23,23',28,28') of each group (A,B) as a group controller (2,23',28'), with which all other control modules (1,23,28) of the respective group (A,B) can communicate via their short-distance communication modules, forming by the control modules (1,2,23,23',28,28') within each group a short-distance network via their corresponding short-distance communication modules, preferably a mesh network, determining, by the server, a new group controller of a group of said one or more control module groups in case of failure of the group controller of said respective group, and announcing said new group controller within said group on the level of the short-distance network, thereafter the other control modules of said group not defined as group controllers establishing their connections via the new group controller, and, during normal network operation, only by the group controller (2, 23, 23') of each respective group, transmitting to the server its own environmental, light and/or control module information and the corresponding information received from other control modules (1, 23, 28) of the respective group via the short-distance communication modules of the other control modules of the respective group;
