Christian Vetter enhanced the evcc-io/evcc repository by developing and refining the ioBroker BMW integration over a three-month period. He introduced new configuration parameters, such as limitsoc, and enforced VIN requirements to improve data integrity and vehicle management. Christian upgraded the BMW Adapter to support generalized real-time data streams, refactored configuration logic using YAML and jq, and resolved issues with state of charge retrieval. He also improved API-level data fidelity by ensuring native data types and simplifying climate status filtering. His work focused on adapter management, configuration management, and YAML templating, resulting in more reliable integrations and streamlined analytics.
November 2025 monthly summary for evcc-io/evcc: Delivered API-level data fidelity improvements for the ioBroker BMW integration by returning native data types and improving climate status filtering. These changes reduce client-side parsing effort and enhance data accuracy for downstream dashboards and automations. Maintained clear commit trace (#24930) with hash 5b5c4553774f952a8794feba8fb53f6b76c2d22d to enable easier reviews and rollbacks. Overall impact: more reliable integration, faster analytics, and reduced operational overhead due to fewer data-type conversions.

October 2025 — Key features delivered include the BMW Adapter upgrade to generalized real-time data streams for battery, charging, and vehicle status with improved parsing, using generalized stream endpoints and updated parsing logic. The work also refactored status and limitsoc configurations to use combined sources and new jq filters for more accurate data interpretation. Major bugs fixed include correcting the SOC path case sensitivity by updating the ioBroker.bmw.yaml template to read stateOfCharge properly from the BMW API. Overall impact: improved data reliability and real-time visibility for EV battery and charging status, reducing data gaps and configuration drift, enabling better decision making and smoother user experience. Technologies/skills demonstrated include adapter upgrades, YAML configuration templating, jq-based filtering, and data-source orchestration.
