I publish a *WeeWX* extension that produces GDD graphs for control of codling moth on apples in addition to other insect crop pests. See the list of extensions at: + https://github.com/weewx/weewx/wiki *weewx-phenology* is listed under XTypes and may be downloaded from the page at: + https://lacusveris.com/Phenology/weewx_extension.shtml Including a GDD XType in existing templates can be a bit fraught because the calculation is a cumulative one that requires iteration from some point in the past. It's not cheap, but neither is *weewx-phenology*'s image generation. At this time of year, there isn't much to see, but you can view a place-holder graphic at: + https://lacusveris.com/Weather/phenology/ ... which shows current conditions in my backyard. The GDD report is at: + https://lacusveris.com/Weather/phenology/cumulative_growing_degree_days.html Suppose you untarred the *weewx-phenology* archive to ~/weewx-phenology, then the template that produces the GDD report may be seen at ~/weewx-phenology/skins/Phenology/cumulative_growing_degree_days.html.tmpl. Be forewarned: It's messy. Mostly it's *python* variable assignments and shows the day date looping required. - -- .. Be Seeing You, .. Chuck Rhode, Sheboygan, WI, USA ..
