4. Operating Instructions

4.1 Smart App Control

The Tuya Smart or Smart Life app provides comprehensive control over your GX-03 timer:

• Remote Activation/Deactivation: Turn watering on or off for each zone from anywhere.
• Schedule Management: Create, edit, or delete watering schedules for both zones.
• Monitoring: View current watering status and potentially integrate with weather data for smart adjustments.

4.2 Independent Zones with Custom Plans

The GX-03 features two independent watering zones. Each zone can be configured with up to 10 individual watering schedules, allowing for precise and customized irrigation without interference between zones.

4.3 Flexible Watering Modes

The app offers various automatic watering options:

• Specific Weekdays: Set watering for chosen days of the week (e.g., Monday, Wednesday, Friday).
• Odd or Even Days: Automate watering based on the calendar day (odd or even).
• Custom Intervals: Schedule watering every 'X' number of days (e.g., every 3 days).

Each mode supports detailed scheduling for up to a full month.

4.4 Cyclic Watering

For advanced control, you can set a repeating watering cycle. Define a start time, end time, duration (1 minute to 24 hours), and interval (1 minute to 24 hours). This is particularly useful for drip irrigation systems or specific plant needs requiring frequent, short watering bursts.

4.5 Rain Delay & Manual Watering

• Rain Delay: Conserve water by pausing scheduled irrigation for 1 to 7 days during rainy weather. This feature can be set manually via the app.
• Manual Watering: Activate watering instantly for a specified duration directly from the device's buttons or through the app for immediate needs.

5. Maintenance

• Battery Replacement: The device is powered by batteries. If you notice inconsistent performance or connectivity issues, replace the batteries. Use high-quality alkaline batteries for optimal performance and longevity.
• Cleaning: Periodically inspect the brass inlet and hose outlets for any debris or mineral buildup. Clean with a soft brush and water if necessary.
• Winterization: Before freezing temperatures, disconnect the timer from the faucet and hoses. Drain any remaining water and store the device indoors in a dry, protected area to prevent damage from freezing.

6. Troubleshooting

• Device Not Connecting/Pairing:
  • Ensure your Zigbee gateway is powered on and connected to a 2.4 GHz Wi-Fi network.
  • Verify the timer is in pairing mode (indicator light flashing).
  • Move the timer closer to the Zigbee gateway to improve signal strength.
  • Check if your app and Zigbee gateway firmware are up to date.
• Watering Not Activating:
  • Check battery levels and replace if low.
  • Ensure the faucet is fully open.
  • Verify that schedules are correctly set in the app and not overridden by rain delay or manual settings.
  • Confirm the device is still connected to the Zigbee network in the app.
• Leaks from Connections:
  • Ensure all connections (faucet to timer, timer to hose) are hand-tightened.
  • Check for worn-out rubber washers and replace if necessary.
  • Apply plumber's tape to threads if leaks persist.
• Inaccurate Timer Functionality:
  • Some users report a default timeout for valves. Ensure the 'Irrigation Timer' field in the app is set to your desired duration.
  • If using Home Assistant (ZHA), ensure your Home Assistant version is updated for proper device recognition and control.
