Contributed to the mib1185/homeassistant-core repository by enhancing the ebusd integration for Vaillant 700 heating systems within Home Assistant. Developed and integrated three new sensor types—FlowTemperature, OutsideTemperature, and TotalEnergyConsumption—using Python to provide more granular monitoring and energy analytics. This work improved the visibility of heating system performance and energy consumption, enabling users to access critical data through Home Assistant dashboards and automations. Focused on home automation and IoT development, the implementation supported better diagnostics and automation opportunities. Collaboration was demonstrated through co-authored commits, reflecting attention to code quality and integration within the broader Home Assistant ecosystem.
