During April 2026, Seegel Systeme added microampere (µA) unit support for electric current measurements in the Home Assistant core repository, enhancing precision for low-current device monitoring. They updated unit definitions and conversion logic in Python, expanded unit tests to ensure correct µA handling, and integrated these changes into backend systems. Seegel Systeme also aligned documentation across home-assistant/core and developers.home-assistant, using Markdown and technical writing skills to ensure consistent guidance for developers and users. This work improved data quality for dashboards and automations, demonstrating depth in API design, backend development, and thorough validation through comprehensive test coverage and documentation updates.
