During April 2025, Ferran developed a Modbus TCP integration for Kathrein chargers within the evcc-io/evcc repository, enabling seamless control, monitoring, and diagnostics of charging sessions and charger parameters. He implemented the interface in Go, leveraging configuration management and templating to streamline deployment and support hardware interoperability. By connecting embedded systems and hardware integration skills with the Modbus protocol, Ferran’s work allowed end-to-end visibility of charger status and parameters, reducing manual monitoring and simplifying issue diagnosis. This feature expanded evcc’s supported hardware, allowing customers to deploy Kathrein chargers more efficiently and with greater operational insight, reflecting focused and in-depth engineering.
