I have noticed that my realtime wind direction guage is showing completely the opposite reading to which the graphs are showing, the graphs are correct.
Is there any adjustment in Cumulus to correct this anomoly.

Re: Realtime wind direction guage incorrect
It's not an issue with Cumulus, it's due to the Fine Offset wind vane, which can often appear to be almost random. Cumulus averages the direction out over a period of 10 minutes, which helps somewhat. The realtime gauge shows the current direction from the station, the same as the 'Bearing' figure on the main screen. The 10-minute average is shown on the main screen as 'Avg Dir'. The graph plots both sets of values. If you look at the red crosses on your graph, you will see that they show many different directions over a short period of time. It's that value that the realtime gauge is showing.
Even the 10-minute average on your graph is fluctuating far too much to be useful. You can increase the averaging period, which may help a little, by stopping Cumulus and editing cumulus.ini. Add a line "AvgBearingMinutes=X" to the [Station] section, where X is the number of minutes to use. Note that this won't affect the realtime gauge, which will always show the current direction.
