Contributed to the openhab/openhab-addons repository by developing a native TimescaleDB persistence service for OpenHAB, focusing on scalable time-series data storage with downsampling and retention policies. Leveraged Java and SQL to extend the database schema, introducing metadata tagging and JSONB configuration storage for enhanced data management and flexible querying. Improved the robustness of database connections by implementing normalization and validation for TimescaleDB JDBC URLs, including support for URLs without the 'jdbc:' prefix. Updated documentation and expanded unit testing to ensure reliability and ease of use. The work emphasized database management, schema design, and resilient integration within the OpenHAB ecosystem.
