Worked on the google/digitalbuildings repository to enhance telemetry quality and configuration consistency for CO2 deadband concentration setpoints. Focused on configuration management and data modeling, the work involved introducing a new YAML-based telemetry field and standardizing field naming across configuration files to reduce configuration drift. The approach emphasized traceability, with all changes documented through multiple commits, ensuring clear documentation and easier future maintenance. By aligning naming conventions and extending telemetry, the updates improved data quality and observability, supporting more reliable control decisions. No production incidents occurred during this period, reflecting careful implementation and attention to configuration management best practices.
