283 seems to have fixed the serial port closure issue. Thanks.
I've got some funkiness happening with some readings not showing up and the graph no updating with any of the wind readings.
I've included a screenshot of the OSX and Windows screens side by side.
The Average Wind Speed isn't updating, the windchill is wrong (due to wind speed?), the maximum gusts are wrong, the maximum temperature is wrong and the minimum temperature is wrong. You can also see the timestamp for the temperature readings is wrong.
The OSX version has just been running a few minutes and the Windows version has been running for quite a few days now.
