On the app, under Settings->Preferences->Rain, have you checked these settings?  These control which conditions, either actual, or predicted, rain amounts will change the watering schedule.

      Hi Ken yes I have checked the setting you mentioned. The lowest setting I can select is 1mm of rain fall. I've asked about having the option to select 0mm (no rain fall) as the app has recorded rain fall when I've not had any rain at all. Hope it makes sense
