Oops... Suddenly found out what I had done wrong: I had unzipped the nightly build without using any directories, so everything was just dumped into the main directory.

So that's why I couldn't see the Oregon wind sensor. Now I have done it correctly
, but now it doesn't see my wind sensor at all!
I see my fine offset thermometers, and I see the two Oregon thermometers/hygrometers I have running, but the wind sensor just doesn't appear! Any idea what that can be? I unpacked the nightly build to a fresh directory, and then I copied my default.xml over to there. In the log it says I'm running 2.1-SNAPSHOT-9ad63. That is the correct build, right?
Edit: Finally got it working, thanks!

I had to do a full restart of the virtual machine that runs my setup, and suddenly the wind popped in.

But I'm afraid you have a slight error there: It shows a tenth of the correct wind speed. So it shows 0,6 m/s while it should have been 6. This goes for both wind (which is actually the gusts) and average wind.
Edit 2: For some reason the wind sensor creates a new item in the log (when I want to create something new), even if it says excisting. Other sensors are only mentioned once in the log and after that only the time since the last action is changed.
