During November 2025, contributed to the esphome/esphome and esphome/esphome-docs repositories by developing and documenting optional humidity sensor support within the climate_ir component. Leveraging C++ and Python, integrated sensor data to enable simultaneous monitoring of humidity and temperature, enhancing the fidelity of climate control systems for IoT applications. Authored comprehensive documentation in Markdown to ensure users could easily adopt the new feature and understand its configuration. This work addressed the need for more granular environmental monitoring, supporting potential energy optimization and improved user experience. The approach demonstrated a focus on embedded systems, sensor integration, and clear technical communication.
