Developed and integrated a new power profile for the Signify Hue White Ambiance Light within the bramstroker/homeassistant-powercalc repository, focusing on accurate energy estimation for the 929003099102 model. Leveraging data modeling and power consumption analysis, the work involved creating a dedicated model.json to document measurement methods and consumption characteristics, ensuring reproducible results. The update included asset uploads and the removal of outdated data, such as the obsolete color_temp.csv, to maintain repository clarity. By enhancing the precision of energy calculations using JSON and structured data, the contribution improved cost visibility and informed automation decisions for Home Assistant users.
