this one turned out to be quite popular so I added a few extra things:
- added possibility to set dry day threshold (i.e. a value which still counts as “dry day”. You can now set the defaults in the setup and user can then change this themselves on the page)
- improved rounding
- minor bug fixes
Note: Don´t forget that if you are updating this plugin you need to re-save your settings and specify the new parameters, even if you want to leave everything default, you have to hit Save to refresh the settings file.
