During September 2025, contributed to the esphome/esphome and esphome/esphome-docs repositories by delivering enhanced BL0940 device capabilities and comprehensive documentation updates. Developed new configuration options for the BL0940 component, including dynamic calibration using number entities, a reset button, and support for legacy and schematic-based modes, improving flexibility and accuracy in power monitoring. Updated documentation to clarify UART communication, sensor readings, and calibration parameters, adding visual aids to support user understanding. The work emphasized cross-repository alignment, ensuring that feature implementation and user guidance evolved together. Utilized C++, Python, and Markdown, applying skills in embedded systems and configuration management.
