HÄHL GmbH

Cloud Connected IoT Rolls

The successful collaboration between the internationally active mid-sized company HÄHL GmbH and Medialesson led to the development of the pioneering product “Cloud Connected IoT Rolls”, which connects the company’s rollers to the cloud.

The rollers are in use at various sites worldwide, including in China. Equipped with a range of sensors, they continuously transmit data from multiple measurement points. This data is captured in near real time and processed in the cloud. Using advanced calculations, the performance of each roller is evaluated and sent to Power BI, where it is visualized on insightful dashboards.

This cutting-edge technology enables HÄHL GmbH to support its customers in maintaining the highest level of product quality - helping them secure a leading position in the market.

Solution implementation

The solution was planned and developed in close collaboration with the HÄHL team. The infrastructure is continuously provisioned using Infrastructure as Code (IaC).

Before a production version is released, extensive testing ensures the full functionality of the solution within a separate test environment as part of the CI/CD (Continuous Integration/Continuous Deployment) process.

To process the large volume of sensor data in real time, the solution leverages Azure IoT Hub. The subsequent calculation of additional values is handled via Azure Stream Analytics Jobs. Results are then forwarded to the customer’s Power BI platform using Azure Functions, where they are visualized.

All features are accessible via REST APIs, secured through Microsoft Entra ID.
