Optimizing Land-Based Fish Feeding with Node-RED

Aquateknikk’s Industrial IoT Solution for Sustainable fish farming.

Aquateknikk uses Node-RED and MQTT in a real-world IIoT system for land-based fish farming. With over 25 locations and 10 to 40 Raspberry Pi edge devices per site, each responsible for calculating and executing feeding. The system integrates with industrial hardware via Modbus and Moxa I/O modules.

Because it’s not just another IoT demo—it’s a real, deployed, and evolving industrial system that feeds thousands of fish every day using Node-RED.

This session dives into how we transformed a fragile, PLC-dependent setup into a resilient, containerized IIoT platform using Node-RED, MQTT, and edge computing. You’ll see how Raspberry Pis are a crucial part of the systems functionality , how we integrated with Modbus and MQTT, and how we built a CI/CD pipeline that supports real-world deployments.

Also some of the current challenges and obstacles that have yet not been properly sovled.

Whether you’re building smart factories, automating greenhouses, or just love seeing Node-RED in action at scale—this talk will inspire, inform, and maybe even make you laugh (yes, we use “frontend for backend and backend for frontend”
