Hydrawise uses local, real-time weather forecasting and the most accurate weather stations
available to fine-tune your irrigation system to current conditions. Water triggers are the settings in your Hydrawise software that can be adjusted based on your watering requirements. When a trigger met the adjusted threshold, it will make the change in the software to either adjust watering schedule or cancel watering.

Smart (ET) Watering
Using forecast evapotranspiration helps to predict the right watering schedule for your zones, giving you a more accurate picture of when the zones will next run.
You can choose whether to use the forecast temperature to predict smart (ET) watering, and whether to use forecast rainfall to delay smart (ET) watering. Watering Schedules will be estimated up to 30 days from today based on forecast and historical temperatures and rainfall. The predicted schedules will be progressively updated each day based on actual weather conditions and new forecasts.
Your watering schedule is updated based on actual weather conditions shortly before your first Program Start Time each day.
You can view the watering adjustments for Smart Watering by clicking here.
