Operating Instructions
Watering Modes
The RAINPOINT WiFi Sprinkler Timer offers three distinct watering modes to suit various irrigation needs:
- Normal Irrigation: Continuous one-time watering. Set a start time, duration, and repeat frequency (e.g., every 3 days, odd/even dates).
- Interval Irrigation: Intermittent watering, ideal for cooling, dust removal, or water-saving. Valves switch on and off at set intervals.
- Cycle & Soak: Splits the total watering time into multiple short cycles with breaks in between. This allows soil to absorb water more effectively and improves watering efficiency.

Setting a Watering Schedule
Use the "RainPoint Home" app to program your watering schedules. You can define start times, water duration (from 1 minute to 12 hours), and watering frequencies (Everyday, Odd Days, Even Days, Interval, or Custom).
The app also provides Smart Plan Recommendations for water-efficient schedules based on your plant and soil profile.
Manual Watering
You can initiate manual watering in two ways:
- Via Timer Button: Long press the timer button on the device to manually water for 10 minutes.
- Via App: Use the manual control option within the "RainPoint Home" app for immediate watering.

Smart Scenarios & Seasonal Adjustment
- Smart Scenarios: Configure the timer to adjust watering based on real-time weather conditions (temperature, humidity, rain). For example, it can skip watering on rainy days or boost hydration during hot spells.
- Seasonal Adjustment: Adjust watering duration from 10% to 200% to match the irrigation needs of different seasons.
