Worked on the mib1185/homeassistant-core repository to deliver a targeted upgrade of the PyDaikin library to version 2.17.2, focusing on maintaining stability and compatibility for the Daikin integration within Home Assistant. The approach centered on backend development and dependency management, ensuring that the integration remained aligned with the latest Home Assistant features and bug fixes. By consolidating the dependency upgrade in the core repository, the work established a repeatable process for future updates. Utilizing Python, the changes reduced the risk of incompatibilities and strengthened the project’s maintenance posture, reflecting a methodical and focused engineering effort over the month.
