Hi Rich,
Could you please try manual water one of the two zones on the Home page of the app and see if two zones still run at the same time? If it still happens, please write to us support@netrohome.com
The blue play button in zone area on the Home page is for manual run for your zones.
Regards,
Netro Support
Hi Douglas, the "new plant" method tries to keep the moisture level very high (above 85%), but doesn't ensure watering every day. Neto does not water that frequent as expected due to weather, soil types, etc.
