Erwin Hymer Group (EHG) is one of Europe's largest manufacturers of motorhomes, caravans, and recreational vehicles. Founded in 1957 in Bad Waldsee, Germany, the company has grown to encompass multiple prestigious brands including Hymer, Bürstner, Carado, Dethleffs, and Elddis.
EHG needed a unified IoT platform to connect and monitor thousands of motorhomes across Europe while streamlining their business operations across multiple brands and countries. They faced challenges with fragmented systems for fleet management, rental operations, and customer service. The platform needed to handle real-time telemetry data from vehicle onboard systems, process millions of IoT events daily, and provide reliable APIs for mobile and web applications.
Built a Java and Kotlin microservices platform with Kafka processing millions of IoT events from connected motorhomes daily. Azure IoT Hub connects to onboard vehicle systems providing real-time diagnostics, location tracking, and maintenance alerts. The microservices expose RESTful APIs powering rental management, fleet tracking, and customer service applications. Deployed on Azure with Kubernetes for automated scaling and high availability across European regions.

The comprehensive platform for Erwin Hymer Group provides APIs that power their web and mobile applications for motorhome rentals, driver management, and fleet operations. Explore the key technologies below to see how this scalable, high-performance solution was built.
