Worked on the hardwario/docs repository to deliver production-ready documentation updates supporting the integration of the Piketronic RPP-R radon probe with the CHESTER Serial/Modbus platform. Focused on technical clarity, the work included detailed markdown documentation covering connection settings, DIP-switch configuration, and measured values to streamline onboarding and field deployment. Sensor integration expertise was applied to ensure accurate representation of device parameters, while Modbus communication knowledge enabled precise documentation of interface requirements. The updates expanded the CHESTER Serial device catalog, improved asset discoverability, and aligned with integration requirements, demonstrating a methodical approach to technical writing and collaborative documentation development.
