• Watering Not Starting/Stopping:
  • Check battery levels in the irrigation controller. Low batteries can cause malfunctions.
  • Verify that the water tap connected to the controller is open.
  • Ensure there are no physical obstructions in the water flow.
  • Check the app for any active schedules, manual overrides, or rain delay settings that might be preventing watering.
• Inaccurate Water Consumption Readings:
  • Ensure the device is installed correctly and there are no leaks before or after the controller.
  • Calibrate the flow sensor if the app provides such an option, or contact support.
• App Crashing or Unresponsive:
  • Clear the app's cache and data, then restart it.
