Sebastian Sucker enhanced the evcc-io/evcc repository by expanding its Home Assistant integration to support direct charging current control and advanced telemetry. He implemented Go-based backend logic and YAML configuration updates, enabling users to set maximum charging current through a new parameter and service call in the Home Assistant vehicle definition. Sebastian also introduced a meter template for retrieving power, energy, current, and voltage metrics, and added support for battery state of charge (SoC) retrieval via a new entity. This work improved automation, monitoring, and interoperability, demonstrating depth in API integration, IoT integration, and configuration management within a complex ecosystem.
Monthly summary for 2025-10: The evcc project delivered a substantial enhancement to the Home Assistant integration, enabling direct charging current control and expanded telemetry. Key outcomes include: - Home Assistant integration: setting the maximum charging current via a new parameter and service call in the Home Assistant vehicle definition, enabling users to control charging current through evcc. - Home Assistant meter template: added a template to connect to Home Assistant and retrieve power, energy, current, and voltage metrics. - Battery SoC retrieval: added support for retrieving battery state of charge (SoC) from Home Assistant meters with a new SoC entity and updated metric handling. These changes were implemented across three commits: c0cb1e4062f4ec7e3c75395ce5987147b2c5c1c6; bd10db550a782081ef34624982efe9505b058e69; ae68505bd2aa4348067dfc0b3a4556a74dec1b60. Impact and business value: - Improved automation and control for end users via direct charging current management from Home Assistant. - Enhanced telemetry and visibility with a dedicated meter template and SoC retrieval, enabling smarter energy planning and cost optimization. - Strengthened integration quality and interoperability between evcc and home automation ecosystems. Technologies/skills demonstrated: - Go-based core integration work and refactoring around Home Assistant integration patterns. - Telemetry and metrics exposure (power, energy, current, voltage, SoC). - Configuration of new entities and parameters to support external control and monitoring. Major bugs fixed: none reported for this period in this repository.
