Dear customer,

he Smart Watering function automatically adjusts the watering duration based on conditions such as weather and soil. If you want to precisely control the water duration and do not want smart zone schedule to override your own programmed schedule, you can set up the Smart Zone level from Advanced to Basic, which only skip rainning days for your programmed schedule.
