nodeG6 Multi-protocol Modular Edge IIoT Gateway

This modular edge IIoT gateway consolidates site monitoring, control, and data processing into a single configurable hub. It supports industrial protocols like Modbus, CAN bus, J1939/OBD2, and OPC UA while securely connecting to AWS, Azure, Google Cloud, Ubidots, or other MQTT endpoints. Local data buffering with SQLite and no-code or script-based automation through Node-RED, Docker, and a Python API help improve reliability and reduce reliance on multiple separate devices.
