Dear customer,

The smart watering function doesn’t support setting watering by specific water volume directly. However, you can adjust the system to calculate water usage based on your needs through these steps:

Go to Settings > Zones > Smart Zone > Mode, select Customized, click Flow Rate below, input the flow rate to calculate the water usage. You can then adjust the smart watering frequency according to the calculated water volume.
Let us know if you need help with the setup—we’re happy to guide you through it!

Thanks,

Netro Support
