Boris - I think I may have found a small bug in the Avg Wind Direction - everything else is working great!
The avg wind shows W or 270d even though it has been E.... I have attached the pics showing the graph vs what the guage is showing....the clientraw.txt file shows the same too:
The green arrow representing actual wind direction looks ok to me.
The red tip displays average wind direction. Meteohub puts the average wind direction of the day in there. So don't expect timely changes. The parameter is named "day1_wind0_maindir_deg" in Meteohub variable list. You can ask for the value by "http://yourmeteohubip/meteograph.cgi?te ... aindir_deg"
