"Plug & Play" installation of a Node on a luminaire basically means that NO installation is required. Tellink's external TSmarT Nodes, whether they use ZHAGA or NEMA plugs, are connected manually (without tools) on the luminaires, in less than 5 seconds. Once the luminaire starts operating, TSmarT Nodes automatically contact the Software Platform, register with it (if authorized), report their exact geo-position, and start operating. Therefore, TSmarT Nodes do not require installation, and installers do not have to worry about performing any geo-location tasks manually or using smartphone APPs, nor about registering the Nodes in the Software Platform.
