Node-RED and n8n
Node-RED and n8n integration for flexible IoT automation
Turn sensor data into action with visual, low-code flows. Connect Sensor-Online to messaging, ticketing, databases and business systems without writing a full application.
500+ customers · 100,000+ active sensors · Trusted by Akademiska Hus, Vattenfall, LKAB and HSB
How it works
From event to outcome.
Event
New data, an alarm or a threshold crossing.
Flow
A visual Node-RED or n8n flow takes over.
Logic
Filter, enrich, transform and route the data.
Outcome
A message, a ticket, a database row or a call to another system.
What you can build
Examples of automations that take minutes, not weeks.
Alerts to your channels
Post alarm messages to Slack and other messaging tools, or send e-mail.
Tickets and work orders
Create a ticket in your service or maintenance system when something goes wrong.
Protocol bridges
Move data between MQTT, REST, webhooks and other interfaces.
Data pipelines
Send sensor data to databases, BI tools and other systems.
Business workflows
Combine sensor events with ERP, CRM and other business data.
Custom dashboards and logic
Build exactly the behaviour your operation needs.
Node-RED or n8n?
Both are supported. Choose by the job.
| Node-RED | n8n | |
|---|---|---|
| Best for | Event-driven flows close to devices and protocols | Workflow automation across business apps and services |
| Style | Visual, flow-based programming in the browser | Visual workflows with ready-made app connections |
| Typical use | MQTT, device data and protocol logic | Messages, tickets, e-mail and business processes |
Node-RED or the rule engine?
Pick the simplest tool for each job.
Use the built-in rule engine for alarms and calculations inside the platform. Use Node-RED or n8n when you need to reach outside it, such as other systems, services or people.

What are Node-RED and n8n?
Node-RED and n8n are visual, low-code tools for building automations by connecting nodes and services in the browser.
Do I need to be a developer?
No. The flows are visual, and many automations need little or no code.
Can I trigger a flow from an alarm?
Yes. Alarms and events can start a flow, for example to send a message or create a ticket.
How does it connect to Sensor-Online?
Through the REST API, webhooks and MQTT.
Does it work on-premise?
Yes. The integrations work with SaaS and on-premise installations.
