I have started to create a module for creating harvest logs with how much you harvest. FarmOS-Asset-link-plugins/Plants at main · jorblad/FarmOS-Asset-link-plugins (github.com) Right now I have hardcoded it to work with count and grams but my plan is try to get it to get the measures from farmOS and populating that in the choice list.
Edit: For now I don’t even know if it is possible to get them but I suppose it should be somehow.
