MQTT Nodes

This document lists and explains the MQTT nodes available in FlowFuse. These nodes are enhanced versions of the standard MQTT In and MQTT Out nodes in Node-RED, designed for FlowFuse users.

They are tightly integrated with the FlowFuse MQTT Broker Service, a built-in, team-scoped broker managed directly by the FlowFuse platform. When an MQTT node is added to the canvas, the MQTT Broker Client is automatically created and configured. This ensures secure, easy communication without requiring any external broker setup or credentials.

Each node extends standard MQTT functionality with automatic configuration and full MQTT v5 support, making it easier to build reliable and real-time communication flows inside FlowFuse.
