Node-RED Integration for Flexible and Powerful IoT Automation

Sensor-Online integrates seamlessly with Node-RED
through a dedicated Sensor-Online node, enabling advanced automation,
custom logic, and powerful integrations within IoT solutions.

This integration makes it easy to combine Sensor-Online services with the
extensive Node-RED ecosystem to build flexible, event-driven, and scalable IoT workflows.

Dedicated Sensor-Online Node for Node-RED

The Sensor-Online node provides a direct and secure connection between Node-RED
and the Sensor-Online platform, simplifying access to data and platform services.

  • Easy access to live and historical sensor data
  • Simple interaction with devices and platform functions
  • Rapid development of custom logic and workflows
  • Reduced integration and development effort

Leverage the Full Node-RED Ecosystem

By combining Sensor-Online with Node-RED, users gain access to thousands of
ready-made nodes for integration, automation, and data processing.

  • Use community and commercial Node-RED nodes
  • Create complex logic using visual flow-based programming
  • Integrate with IT systems, databases, and cloud services
  • Rapidly prototype and deploy new functionality

Use the Built-In MQTT Broker with Node-RED

Sensor-Online includes a built-in MQTT broker that can be directly
consumed by Node-RED for real-time, event-driven processing.

  • Subscribe to live sensor data streams
  • Trigger automation flows based on incoming events
  • Publish processed or derived data back to the platform
  • Enable low-latency and scalable data handling

Modbus Master Integration via Node-RED

Node-RED can act as a Modbus master when integrated with Sensor-Online,
enabling communication with PLCs, meters, and industrial devices.

  • Read data from Modbus TCP devices
  • Write values, setpoints, and control signals
  • Combine Modbus data with IoT sensor data
  • Bridge industrial OT systems with modern IoT platforms

Swagger-Documented REST API for Full Platform Control

Sensor-Online exposes its full functionality through a
Swagger-documented REST API, which can be easily used within Node-RED flows.

  • Read and write sensor data via API
  • Manage devices, metadata, and configurations
  • Integrate analytics and external services
  • Create closed-loop automation workflows

This allows API-driven logic to be combined with real-time MQTT and
industrial protocols in a single automation flow.

Powerful Customization Without Vendor Lock-In

The combination of Sensor-Online and Node-RED provides maximum flexibility
without locking users into proprietary scripting environments.

  • Open standards and well-known technologies
  • Visual flow-based logic instead of hard-coded scripts
  • Easy maintenance and long-term extensibility
  • Freedom to tailor each solution to specific project needs

From Simple Automation to Advanced IoT Solutions

Whether the goal is simple data routing or advanced industrial automation,
Sensor-Online together with Node-RED provides a powerful foundation.

By combining MQTT, Modbus, REST APIs, and flow-based logic, organizations can build
highly customized, scalable, and future-proof IoT solutions with minimal development effort.
