NEMA

Wireless Lighting Control for Smart Outdoor Infrastructure

The S4i NEMA Node is a compact Bluetooth Low Energy (BLE) Mesh lighting controller designed to bring intelligent wireless control to outdoor lighting installations. Installed directly onto a standard ANSI C136.41 7-pin NEMA receptacle using a simple twist-lock connection, it converts wired DALI or 0–10V lighting systems into a secure, scalable wireless network. 

Built around the Casambi ecosystem, the NEMA Node enables remote commissioning, real-time monitoring, energy metering, adaptive lighting control and cloud connectivity without requiring additional communication wiring.

Whether upgrading existing infrastructure or deploying new smart lighting installations, the S4i NEMA Node provides a simple pathway to connected lighting.

Wireless Intelligence at Every Luminaire

The S4i NEMA Node installs directly onto each luminaire, allowing every fitting to become part of a secure BLE network. With integrated DALI bus power, energy monitoring, photocell functionality and wireless communications, each node becomes an intelligent control point capable of operating independently while contributing to a resilient distributed network.

Supporting both DALI and 0–10V lighting systems, the NEMA Node is equally suited to retrofit projects and new smart infrastructure deployments.
