During April 2025, Breiti contributed to the evcc-io/evcc repository by implementing support for the KEBA KeContact P40 and P40 Pro models, enhancing hardware compatibility and data reliability. Breiti introduced new Modbus registers and YAML configuration options, carefully differentiating between P30 and P40 models to streamline integration. To address inaccuracies in energy reporting for older P40 firmware, Breiti developed a dynamic energy factor, improving the precision of energy readings. The work leveraged Go for API development and embedded systems integration, demonstrating a thoughtful approach to hardware-software interaction and maintainability, with a focus on solving real-world energy monitoring challenges.
