Node-RED handles hardware-close event routing and protocol translation at the edge; n8n handles downstream business logic, scheduling, AI enrichment, and multi-system orchestration. Paired via MQTT.
Eclipse Kura serves as an edge gateway handling diverse device protocols (Modbus, OPC-UA, BLE), while Node-RED provides visual flow programming for data orchestration. Kura-managed data flows into Node-RED for processing and routing.
Telegraf collects metrics from industrial protocols and devices, while Node-RED orchestrates data flows visually. Telegraf feeds data into Node-RED pipelines for processing and routing.
QuestDB serves as the time-series data store for Node-RED flows in IIoT deployments. Node-RED handles data collection and transformation, while QuestDB provides high-performance storage and SQL analytics.
Grafana handles dashboards and alerting while Node-RED handles data flow orchestration and protocol bridging. Together they form the middle layers of the MING stack, with Node-RED collecting and routing data into databases that Grafana queries for visualization.
