Modern businesses run on many different systems—ERP, machines, sensors, cloud apps, and more. The real challenge isn’t just running them, but making them talk to each other in real time, without fragile, one-off integrations.
MQTT for Unified Namespace, Node-RED, and n8n are the building blocks that keep data moving and processes automated, so systems work together as a single ecosystem.
MQTT for Unified Namespace – The IoT Backbone
MQTT is a lightweight messaging protocol designed for fast, reliable communication between devices and systems.
- Why it works: Uses a publish/subscribe model, so any connected system can send or receive data instantly.
-
Why it’s adopted: Standard in IoT, manufacturing, and industrial automation for its low bandwidth use and reliability.
A Unified Namespace built on MQTT becomes the single source of truth for live operational data across the enterprise.
Node-RED – Visual Automation for IoT and Beyond
Node-RED is a flow-based development tool that connects devices, APIs, and services using a visual editor.
- Why it works: Makes complex integrations possible without heavy coding.
- Why it’s adopted: Huge library of pre-built nodes for everything from databases to hardware interfaces.
n8n – Flexible Workflow Automation
n8n is an open-source automation platform for connecting cloud apps, APIs, and internal systems.
- Why it works: Handles multi-step workflows with conditions, loops, and error handling.
- Why it’s adopted: Self-hostable alternative to Zapier or Make, with full control over data.
Why Use Them Together
- MQTT streams live data from devices and systems.
- Node-RED processes and transforms that data for operational needs.
- n8n handles business-level automations across cloud and on-premise apps.
The combination bridges the gap between shopfloor, IT systems, and cloud services—making real-time, end-to-end automation possible.
The Result
Data flows where it’s needed, instantly and securely. Processes that used to require manual work happen automatically. Systems stay connected without relying on fragile, custom point-to-point integrations.
