Thanks Tom Final questions for the night, I promise 🤣😂
Would you put this one the database, or just let WeeWx calculate it using the xtype each time? Second, is there an API or interface or whatever where another application can query WeeWX for some sort of weather data? In this case, I'd like my irrigation software to query WeeWX for the ET, total rain, and chill hours of a given time frame. Or do I just have to read the database directly?
