The zone area is used for calculating water usage and it will not affect watering amount. Could you please let us know which zone only watered for 1 or 2 min? Could you please send us email to firstname.lastname@example.org with your Netro account registered email?
We will look into this issue.
We checked your zone Spate Casa, however the smart schedules are about 13 mins. Did you change the smart zone settings? Currently we are not able to check the one minute issue.
What you are looking at is the watering duration for the instant manual run (not the user program or smart watering) in the zone sections shown on the home page. The system remembers the last duration of the instant manual run and displays that on the home page.
Please tap on the "1:00" text and there will be a window pop up for changing that value.
