Further info -
If I launch WDLive, it correctly displays the realtime wind speed and direction, and the gust meter shows the gusts. The number shown in the gust meter of WDLive exactly matches what is shown in the wind speed meter on the main display of WD. So it seems that the Main screen is actually showing wind gust in the windspeed meter and not current windspeed. I hope this information helps to sort out what’s got crossed here.
Thanks!
Steve
