The station is at a vacation home and I was there on Oct 14 so it is
possible that I upgraded to 3.8.2 at that time. But it's curious that I
see periods as short as 6 hours of similar behavior before the upgrade.
Maybe the software algorithm couldn't calculate higher precision with the
data a
Hello, Mike
Wind direction downloaded from the logger is limited to 22.5 degrees of
precision.
Previous to V3.8.2, wind direction was always calculated in software, even
when hardware values were available, which could result in higher precision
(although not necessarily accuracy). See issue #336
I'm running Weewx 3.8.2 on a Raspberry Pi with Rasbian Jessie. Weather
station is a Davis Vantage Pro2 wired.
I'm getting the wind direction reported at only the major compass points:
(0,22.5,45,67.5,90,112.5,135,157.5,180,202.5,225,247.5,270,292.5,315,337.5).
This behavior started on Oct 14
