You've indicated that group_moisture is to be measured in VWC, but only for the US measurements. For METRIC and METRICWX, it will still be in centibar.
I think what's happening is that weewx is trying to convert from whatever it has (probably centibar) to VWC, but does not know how. Are you using METRIC and/or METRICWX anywhere? In particular, in the plot? On Wed, Nov 6, 2024 at 1:47 PM bgra...@umw.edu <bgrat...@umw.edu> wrote: > I am using a Seeed S2105 soil moist/temp sensor on a VP2 with weewx > 4.10.2.
