Aus you describe it, there is no unit "VWC". The unit of the reading is percent. So the unit group is "group_percent" and the unit is "percent".
weewx.units.obs_group_dict['soilMoist1'] = 'group_percent' If you want to see the text "VWC" after the value, you can put it there as a constant text. Whether this is enough or not depends on the driver. Please, try this first. bgra...@umw.edu schrieb am Donnerstag, 7. November 2024 um 16:22:56 UTC+1: > Thanks, Karen.
