Worked on the evcc-io/evcc repository to enhance the accuracy of energy measurements for Solax meters by addressing a specific scaling issue in the configuration. Focused on configuration management and data representation using YAML, the developer adjusted the energy scale factor to improve the precision of grid energy accounting. This targeted bug fix improved data quality for billing, reporting, and analytics by reducing discrepancies between production and grid energy readings. The work included thorough validation to ensure measurement consistency and established clear traceability by linking changes to relevant issues and commits, supporting future audits and streamlined root-cause analysis.
