3. App Installation & Pairing
Download the Smart Life app from your smartphone's app store. Follow the in-app instructions to connect the RF Gateway to your 2.4GHz WiFi network. Once the gateway is connected, pair your sprinkler timer(s) with the gateway. One gateway supports pairing with up to 20 RF water timers.

5. Watering Log
The app maintains a watering log, allowing you to track usage and history for better water management.
Maintenance
1. Leak-Proof Design & Anti-Clog Performance
The water timer features a 360° brass rotating joint for durability and a secure, leak-proof seal. A built-in metal filter blocks dirt and debris, preventing clogs and reducing maintenance. Regularly check the filter for accumulated debris and clean as needed to ensure optimal water flow.

2. Battery Replacement
When the app indicates low battery, replace all four AA 1.5V alkaline batteries. The lifespan of batteries will vary based on usage frequency.
3. Weather Resistance
The device has an IP65 waterproof rating, allowing it to operate reliably in rain, snow, and sunlight. However, for prolonged periods of freezing temperatures, it is recommended to disconnect the timer and store it indoors to prevent damage.
Troubleshooting
- Device not connecting to app: Ensure the RF Gateway is powered on and within range of your 2.4GHz WiFi network. Check that the sprinkler timer has fresh batteries and is within range of the RF Gateway. Restart both the gateway and the timer if necessary.
- No water flow: Verify that the faucet is fully open. Check the built-in filter for clogs and clean if needed. Ensure the water pressure is adequate (up to 35kg supported).
- Leaks at connection points: Tighten all connections. Apply plumber's tape to threads if leaks persist. Check for damaged washers and replace if necessary.
- Scheduled watering not activating: Confirm that schedules are correctly set in the Smart Life app. Check the rain delay status; if active, watering will be paused. Ensure batteries are not low.
