I recently installed VirtualVP onto my weather PC in an effort to combat the Vue USB dropout issue. This has worked well so far with one exception.
Ever since I changed Cumulus from reading the data directly from the station via COM port over to collecting the data via VirtualVP I noticed that the "Average" wind speed and the "Gust" wind speed were extremely close together all the time.
Example, in the past I'd see Average 15, Gust 22km/h. But now I was seeing Average 21, Gust 22km/h.
I kept an eye on Cumulus and noticed this:
At 12:38pm, we had a gust to 25km/h
At 12:40pm, gust was still listed as 25 km/h.
But at 12:41pm, gust dropped to 21km/h.
Then at 12:42pm to 19km/h.
At 12:45pm, we had another gust to 27km/h.
By 12:48pm, the gust value dropped again.
I checked the "Nov12log.txt" file and found that the "10 minute Gust" value is only displaying for 3 minutes instead of the 10 minutes it is supposed to.
I checked the old "Oct12log.txt" file and found that it was previously working fine and correctly displaying for 10 minutes, up until the day I installed VirtualVP, from then on it has been displaying a 3 minute Gust instead of a 10 minute Gust.
I haven't been able to find anything about this issue online, though I did find that the options "AvgSpeedMinutes" and "PeakGustMinutes" could be added to the cumulus.ini file.
So I added both and set them both to 10 minutes, e.g. "PeakGustMinutes=10", "AvgSpeedMinutes=10". Restarted cumulus and found no change.
This is quite frustrating and is making my wind data look odd having the wind speed and gust so close together.
