It seems as if the wind-direction shown is not right according to the Ultimeter 2100 display and other software (WVS and Data-text tool). The direction looks as if it "stops" at around 230-240 degrees. It should vary much more towards 300-360 degs. (See attachment).
did you try if graphs generated by meteohub do show the same problem?
If so it might be a bug in how Meteohub gets wind direction data from your Ultimeter station. There are just a very few Ultimeter stations runnning with Meteohub.
