Hi,
Firstly, I have a Sprite and love it! Easy to install, easy to set up and I'm really impressed with it.
I have a smart water meter so I know exactly how much water each zone uses and I can see that the Netro Sprite's estimate of water used during irrigation is about 75% of the actual usage as reported by my water meter. This means that I am probably over watering.
Is there an easy way in the app to calibrate the expected flow rate (litres/minute) of a zone's sprinklers such that the smart algorithms deliver closer to the amount of water they think is needed? Or put it another way, instead of calculating it needs to run a zone for say 10 minutes, they would just run for 7.5 minutes.
