I could use a reminder on how to do this - it's been a little while.

How can I save windSpeed to the archive as 0 instead of NULL if there's no wind for that archive interval?

If there is no wind, windSpeed is always stored as 0, never null.

Or, do you mean wind direction?

No I mean windSpeed. I saw the force_null for wind direction. For some reason I have null for wind speed, when I'm thinking it was 0.

I misread this originally. Why would anyone want to plot the log (logorithm) of the wind speed. Iog 0 is 1 not null. Confusion.

And then I read it correctly. :)

I would guess it was emitted that way by the driver.

There's nothing I can think of in WeeWX that would force a zero windSpeed to null (None).

Possibly - thanks! Will dig deeper into that
