Setting up a Personal Weather Station (PWS) to report data to Windy and accessing cloudiness history for your location can be done with a few steps. For integrating your PWS, you’ll need to ensure it's compatible with Windy and supports data sharing via APIs like Weather Underground or similar services. Create an account on Windy and navigate to the PWS section to link your station. For viewing cloudiness history, Windy may not directly offer historical cloud data, but third-party weather platforms or local meteorological services could provide this.
