A method for managing an outdoor lighting network (110,120,130) using a central management system, the outdoor lighting network comprising a plurality of OLN devices, the method comprising: identifying attributes of the OLN devices, wherein identified attributes are selected from a group of static attributes relating to a OLN device, wherein the static attributes are selected from a group consisting of: device type, device name, device location, device model, and device manufacturer; the central management system grouping OLN devices having corresponding ones of said identified attributes into at least one attribute group, wherein said grouping further comprises: verifying a correlation among attributes within an attribute group, further comprising removing attributes lacking correlation among said attributes within said attribute group; the central management system collecting attribute data from selected ones of the OLN devices in each of the at least one attribute group, wherein collecting attribute data further comprises collecting dynamic attribute data relating to a OLN device, wherein said dynamic attribute data is selected from a group consisting of: dimming level, load current, load voltage, and temperature; the central management system determining a status of each attribute of OLN devices within the at least one attribute group based on the collected attribute data from the selected ones; the method being characterized in that: the collecting of the attribute data from selected ones of said OLN devices is performed at a known period, P and comprises: defining a ratio M/N, wherein N is a number of devices in a corresponding attribute group and M is less than N; and for each device within a corresponding attribute group generating a random number R, wherein R is in the range of 0 and 1; and when R < M/N, transmitting a corresponding attribute value associated with the respective device. identifying attributes of the OLN devices, wherein identified attributes are selected from a group of static attributes relating to a OLN device, wherein the static attributes are selected from a group consisting of: device type, device name, device location, device model, and device manufacturer; the central management system grouping OLN devices having corresponding ones of said identified attributes into at least one attribute group, wherein said grouping further comprises: verifying a correlation among attributes within an attribute group, further comprising removing attributes lacking correlation among said attributes within said attribute group; the central management system collecting attribute data from selected ones of the OLN devices in each of the at least one attribute group, wherein collecting attribute data further comprises collecting dynamic attribute data relating to a OLN device, wherein said dynamic attribute data is selected from a group consisting of: dimming level, load current, load voltage, and temperature; the central management system determining a status of each attribute of OLN devices within the at least one attribute group based on the collected attribute data from the selected ones; the method being characterized in that: the collecting of the attribute data from selected ones of said OLN devices is performed at a known period, P and comprises: defining a ratio M/N, wherein N is a number of devices in a corresponding attribute group and M is less than N; and for each device within a corresponding attribute group generating a random number R, wherein R is in the range of 0 and 1; and when R < M/N, transmitting a corresponding attribute value associated with the respective device.
