As the develop of the IoT street lighting, years ago, most of the intelligent using NEMA receptacle which can support 7pins with driver 0-10V, PWM...dimming, but there is not uniform standard.

Now ZhaGa want to uniform the standard, and with smaller size for more lights which can using IoT, Zhaga receptacle has 4pins, which can using the smaller hole.

ZIYUM provide the IoT street lighting through LoRa protocol, with ZhaGa receptacle for both gateway and nodes, which optomize the convenience for mounting and maintance.
