in the SMART Advanced zones section of the APP in the SI system the mm/hour scale goes from 10 to 100
in the US system Cubic inch per hour [in³/h] from 0.1 to 5

the data refers to the single zone therefore VALVE in my case PIXIE 1. 

The scale of values used does not seem to be correct a 3/4 hose with a pressure of 1 Bar brings about 9000 liters per hour 

perhaps the data in the app and mm³/seconds and in³/second I'm doing something wrong.
Thanks for the reply
