<![CDATA[Station upload API v2 - wind direction]]>The new API only accepts wind direction values in the range 0-359.

Cumulus MX defaults to the common convention of using 0-360 for direction, where zero is used for no direction when the wind speed is zero. But 0 or 360 is commonly used for north.

This worked fine with the v1 API, but users are now getting uploads rejected when they report the direction as 360.

When calculating the remainder of the division by 360, the value 360 ​​automatically becomes 0, closing the compass cycle. For example: 180 % 360 = 180 and 360 % 360 = 0.

Generally, in meteorological codes (SYNOP, METAR ...)
0 stands for calm
360 for wind from north.
