Account - Watering Type - Smart (ET) Watering

Smart (ET) watering is an automated watering schedule that uses information about environmental conditions to ensure your plants get the optimal amount of water. Evaporation will draw moisture from your garden, while rainfall and irrigation will add moisture. Understanding these conditions allows Hydrawise to decide when the time is right to water your garden. ET stands for evapotranspiration and is explained further in the diagram below.

For each zone, you will have to assign the watering length and peak watering frequency:

  • The watering length is how long watering needs to run to fully water your zone.
  • The peak watering frequency is how often you would normally water this zone during your peak irrigation period.

The controller will vary your watering frequency based on actual evaporation and rainfall in your area on a day to day basis.  In contrast to Time Based Watering and Virtual Solar Sync, Smart Watering will always water a zone for the same length of time and it will vary the frequency of watering based on temperature and rainfall.
