Hello, I have finally found the problem. Seemingly the image generator is not case sensitive with the signal names. The input signal was named 'rain_RG11'.
The unit group system IS case sensitive because in my plugin I linked weewx.units.obs_group_dict['Rain_RG11'] = 'group_rain' And so I got a graph but with no units on the y-axis and no conversion.
