Eclipse Hono integrates with Node-RED

Overview

Node-RED is a visual programming tool commonly used in IoT workflows. Eclipse Hono exposes device telemetry, events and command responses through AMQP 1.0 and Kafka interfaces. Node-RED can consume these streams using the node-red-contrib-amqp or node-red-contrib-kafka nodes, making it easy to build event-driven flows on top of Hono.

Integration Architecture

1. Devices connect to Hono via any supported protocol (MQTT, CoAP, AMQP, HTTP)
2. Hono forwards normalized messages to an AMQP 1.0 messaging network or Kafka cluster
3. Node-RED connects to this messaging network as a consumer
4. Flows in Node-RED process, transform and route data to dashboards, databases or alerting services

Common Use Cases

• Rapid prototyping of Industry 4.0 pipelines
• Visual alerting rules on telemetry thresholds
• Bridging Hono data to OPC-UA, Modbus or SQL systems via Node-RED's extensive node library

Configuration Steps

1. Deploy Hono with AMQP or Kafka messaging
2. Install the appropriate Node-RED connector node
3. Configure the consumer with Hono's tenant and credentials
4. Subscribe to telemetry and event addresses
5. Build flows to process incoming messages
