OK, that's a different problem, one that is easily solved. Just set option ignore_zero_wind to false <http://weewx.com/docs/usersguide.htm#StdWXCalculate>.
But, I do wonder why I never see this error. Today is a good example. We had an inversion, so the wind was calm all day long, with lots of zeros and lots of null wind directions, yet, WU accepted them all <https://www.wunderground.com/personal-weather-station/dashboard?ID=KORHOODR3#history/tdata/s20161111/e20161111/mdaily> . I wonder if they have multiple servers, each running a different version of their software? -tk On Fri, Nov 11, 2016 at 6:25 PM, Denny Page <[email protected]> wrote: > Thomas, it isn’t that weewx reports a wind speed of zero.
