Timo, you have two problems with the Rose.
First the spacing, set the canvas size to 221 in your HTML. That will match the other gauges.
Second, your ccr file is wrong. You have something like:
"WindRoseData"="[%WindRoseData%]",
you need:
"WindRoseData"=[%WindRoseData%],
Note no quotes around the tag array.
Edit: there is something odd happening with your solar rad gauge too?
Thanks a lot, now it's all ok.
Regarding uv and solar, the oddness is caused by the fact that my uv and solar values are measured by 1-wire sensors. But, the sensors are attached to ha7net, which is not directly supported by WD, so I record values to mySQL database. And then finally I constructed an json/php interface which derives values from database when you open the gauge page. The update is not done in every 10 seconds since the fetch time from database is "slowish" compared to car performance. It's not perfect but good enough

BR - Timo
