To make the issue more clear, I have recorded a video that shows the issue that I am trying to resolve: video <https://drive.google.com/file/d/1WoQfeVg0ZHdXKacnUuNZLpeMxCEKahsB/view?usp=sharing>
As can be seen, the wind speed displayed by the console is not reflected in that displayed by weewx weewx is only show speeds that are multiples of 1.6 kph (i.e. 1mph). Here is an excerpt of what's in my DB for wind speeds and wind gust. MariaDB [weewx]> select round(windSpeed,1) as windSpeed, round(windGust,1) as windGust from archive order by dateTime desc limit 10; +-----------+----------+ | windSpeed | windGust | +-----------+----------+ | 0.4 | 2.0 | | 0.3 | 2.0 | | 0.6 | 4.0 | | 0.3 | 2.0 | | 0.9 | 4.0 | | 0.7 | 3.0 | | 0.8 | 4.0 | | 0.6 | 4.0 | | 0.4 | 3.0 | | 0.4 | 3.0 | +-----------+----------+ The wind gust is obviously in increments of 1mph while the wind speed shows more variation. Based on what I've seen in weewx, I did not think that there were any non-zero wind speeds being recorded but I was obviously mistaken about that. Nonetheless, those speeds are not being displayed in the live widget. Basically, my expectation is that, within reason, the speeds displayed by weewx and that by the console are the same. In case it's not obvious, the skin that I'm using is Belchertown with mqtt integration. On Tuesday, December 9, 2025 at 10:00:35 AM UTC-8 vince wrote: > I’m running two weewx instances as a test.
