Product Overview
The RAINPOINT WiFi Water Timer and Smart Hose Timer with integrated Wi-Fi Weather Station Hub offers an advanced solution for garden irrigation. This system allows for smart, usage-based, and soil moisture-based watering, providing remote control and enhanced weather awareness. The kit includes a Wi-Fi Weather Station Hub that also functions as a real-time internet weather forecaster, indoor/outdoor thermometer, hygrometer, and barometer, tracking environmental data every 3 minutes. The smart water timer supports two watering modes (Irrigation & Mist) and up to six separate watering programs with customizable start times, frequency, and duration. A built-in flow sensor provides real-time push notifications for water cut-offs, leaks, or valve failures, helping to track water usage and save resources.

Operating Your RAINPOINT Smart Watering System
Watering Modes
The smart water timer supports two primary watering modes:
- Irrigation Mode: Standard watering for a set duration.
- Mist Mode: Intermittent watering, ideal for delicate plants or cooling.
Scheduling
You can set up to 6 separate watering programs with customized settings:
- Start Time: Define the exact time your watering program begins.
- Frequency: Choose how often the program repeats (e.g., daily, every other day, specific days).
- Duration: Specify the length of each watering session.
- Watering Basis: Water based on time, water usage, or soil moisture (soil sensor sold separately).
Remote Control & Monitoring
The HomGar App provides comprehensive control and real-time monitoring:
- Real-time Watering Status: View current watering activity.

Rain Delay

Maintenance
- Battery Replacement: The water timer requires 4 AA batteries. Replace them as needed to ensure continuous operation. The hub is powered by a wall adapter and does not require batteries.
- Winterization: During freezing temperatures, it is highly recommended to disconnect the water timer from the faucet and bring it indoors to prevent damage.
- Cleaning: Periodically check and clean the screen filter in the timer's inlet to prevent debris from affecting water flow.
Troubleshooting
- Wi-Fi Connection Issues: Ensure your router is set to 2.4Ghz. The HomGar Series is only compatible with the HomGar App, not the RainPoint App.
- Hub Display Not Showing Timer Functions: The Wi-Fi Weather Station Hub primarily displays weather and environmental data. Timer control and detailed status (on/off, battery, water usage) are managed through the HomGar App on your smartphone.
- Inaccurate Sensor Readings: If the outdoor sensor or soil sensor (if purchased separately) provides inaccurate readings, ensure proper placement and check for any obstructions. Note that the outdoor sensor is not fully waterproof and should be deployed away from direct rain and sun.
- Water Leaks: Ensure all connections (faucet to timer, timer to hose) are tight and properly sealed with Teflon tape and gaskets.
- Timer Not Watering: Check battery levels in the water timer. Ensure the Wi-Fi Weather Station Hub is plugged in and connected to Wi-Fi. Verify that watering schedules are correctly set in the HomGar App.
