How do I change the weather icon?

The easiest way is to look at the icon value being sent by WD. The clientraw description text file contains a description of each of these values and that is what corresponds to the WDL values in the Configurator - usually! There are a few values that are duplicates and some are no longer used which is why there aren’t exactly the same number. In addition you should turn on the Ignore Keywords option as that can sometimes over rule the icon values.
