Hi Simon,

Easy one first; you cannot run WeeWX both as a daemon and directly with a 
single station, it's one or the other.

As for the data, a few observations. All of the speeds on rows where 
usUnits == 1 are in miles per hour. The console data is of course km/h. The 
ARCHIVE and REC rows are km/h and miles per hour respectively and they 
should be the same speeds but in different units, windGust is but windSpeed 
is not. There is a large discrepancy between the console data and any other 
data though the console data is timestamped at least one minute after any 
of the other data.

I guess there is still a lot of variables. In an archive record sense WeeWX 
considers windSpeed to be the average wind speed seen over an archive 
period, windGust is seen as the highest wind speed seen over an archive 
period. When you start looking at loop data it comes down to what the 
station and driver output. is the loop windSpeed the average over the loop 
period or a point in time value. What is windGust in a loop context, the 
highest wind speed seen over a loop period (given the data above I don't 
think that is the case) or the highest value seen over some unknown period. 
You have not said what driver you are using (I believe there is more than 
one that supports your station). Also what tags are you using in the report 
that provides the ARCHIVE row? Finally, what does the console display 
values mean, particularly the wind gust value. You might find this wiki 
entry <https://github.com/weewx/weewx/wiki/windgust> interesting.

Sorry, no real answers and just more questions.
