A method of and a computing device for evaluating lighting quality in a geographic region having a plurality of luminaires arranged therein and a road lighting system are disclosed. Each luminaire in the geographic region comprises a tilt sensor arranged for obtaining a tilt angle of the luminaire. The method is performed by a computing device and comprising the steps of: receiving tilt angles of the plurality of luminaires obtained by tilt sensors of the plurality of luminaires, and evaluating lighting quality in the geographic region with reference to a number of parameters derived from the received tilt angles of the plurality of luminaires.

Method of evaluating lighting quality in a geographic region having a plurality of luminaires arranged therein and a road lighting system

A method () of and an arrangement for communicating, by a server, with a target node device in a network of operatively interconnected node devices, wherein each node device of the network comprises a first communication interface for direct wireless communication with the server, and a second communication interface for inter-node device communication. The server determines () a current communication status of a target node device based on a last received uplink message of the target node device, prior to initiating message exchange with the target node device. The server then may communicate directly () with the target node device via the first communication interface, or via at least one other or delegate node device of the network selected by the server ().
