I added this rather quickly to my weather module. When it’s raining (when the darksky data says it’s raining) you will hear rain for about a minute, then again every 5 minutes (updateInterval) when the data indicates rain. The same goes for “thunder” and “wind”. You would have to find a wind sound file and name it wind.mp3 and place it in the sounds folder of the module itself. Also, you can find and use your own sound files as long as you name them rain.mp3, thunder.mp3 and wind.mp3 and put them in the sounds folder of the module.
