- Rain Delay – A manual control that prevents watering for a specified duration set by the user.
- Rain Sensor – Requires an external rain sensor, which automatically stops watering when rain is detected.
- Weather-based Adjustment – Uses real-time weather data to dynamically adjust the watering percentage based on temperature, humidity, and precipitation.
Although these features serve similar purposes, they operate independently. The chart below outlines their differences:
Trigger | Action | Delay Time | Notes |
Rain Sensor | Triggered by an external rain sensor. Stops watering of stations (except those set to Ignore Rain). | Built-in mechanical delay, adjustable by evaporation vents on the sensor. | Stations that are stopped, or scheduled to run during the delay time will NOT resume after the delay time is over. |
Rain Delay | Manually set by the user. Stops watering of stations for a specified duration (except those set to Ignore Rain Delay). | Defined by the user. | |
Weather-based Adjustment | Watering percentage automatically calculated by the selected adjustment method, using real-time weather data. | No explicit delay time. Watering percentage is calculated based on weather conditions. | Accuracy depends on the proximity of your closest weather station. |
