Wind Chill Reporting Too High

Now that I have CMX 3007 up and running on Linux, the only issue I am having so far is the wind chill being reported. Right now it is 21 °F | -6 °C outside and the wind is blowing at 4.1 mph | 6.6 km/h (10 min. avg.). The wind chill currently being reported is 70 °F | 21 °C

Texas Bubble Gum Machine - I am using a Fine Offset as well, and my Wind Chill is reporting currectly. It's 11F out now, earlier it was reporting 8F wind chill, and even earlier in the day around 20F with a 10F windchill. Running 3007 on Windows and Raspberry Pi Linux. I'm using a WS-2095 from Ambient Weather. Steve just fixed Indoor temperature being reported incorrectly in C all the time. Anything else about your setup that may be different than mine? What OS Linux specifically.

Ubuntu MATE 14.04.1 LTS.

I do notice when I first start CMX and data is first populated that the wind chill reading appears correct then it goes crazy high soon after.

Thanks - it's basically the same problem as the indoor temperature. I'm not quite sure how it's working OK for one of you.

Weird. Hmm. Maybe this will help figure out why it works for me?

It does function for me.

I have the last 60 realtime.txt uploads located here http://www.woodburyweather.com/realtime.log

I attached my Cumulus.ini as well from my Pi.(Edited to remove login info).

I think it's because you have 'calculate wind chill' set. It always does it for FO stations anyway as they don't supply wind chill, but it works in a slightly different way, and with it set you avoid the bug.

I just turned the option on in 3007 (never used it before in Cumulus 1) and the wind chill is reporting correctly. Though I am confused why it has to be enabled whereas I never needed it enabled before. Should anything else be enabled on a FO weather station like calculate dew point?

EDIT...

I updated to 3008 and turned the above option off. Wind Chill is working just fine. Thanks Steve!
