Hi. If you mean temporarily stopping watering, you can tap the circle on the app's home page and then select Pause, or you can use the physical buttons on the controller to pause watering.
If you mean suspending watering for a period of time, there is a Water Delay feature in the upper-right corner of the Schedule page. This allows you to prevent all schedules from running for a specified period.
If you need to stop your irrigation system for an extended period, you can use Standby Mode in the Settings page. This will place the controller into standby mode and prevent any schedules from running.
