If your controller has been offline in the app for hours, follow these steps to diagnose and resolve the issue:

1. Check the Controller’s Indicator Light

If the indicator light is OFF:

. Possible Cause: Short circuit or power issue.

. Solution:

1. Power cycle the controller:

Unplug the power adapter, wait 20 seconds, then reconnect.

2. Test for a short-circuited solenoid valve:

Manually run each zone one by one (if your controller has buttons).

If the controller suddenly shuts off when activating a specific zone, that zone’s solenoid valve may have a short circuit.

  . Example:

Zone 1 & 2 run normally → No issue.

Zone 3 causes the controller to shut off → Short circuit in Zone 3’s solenoid valve.

3. Safety Note:

If a short circuit is detected, avoid handling wiring yourself—contact a professional for repair to prevent electric shock.

If the indicator light is FLASHING YELLOW:

. Possible Cause: Wi-Fi connectivity issue.

. Solution:

1. Check your home Wi-Fi:

Ensure your router is working (test with another device).

2. Verify Wi-Fi credentials:

Confirm the network name (SSID) and password haven’t changed.

If they have, update them in the controller’s settings.

3. Reconnect to Wi-Fi:

Go to: App Settings → Controller Settings → Update Wi-Fi Network.

How do I update Wi-Fi on my controller?

4. Restart the controller:

Unplug for 10 seconds, then reconnect.

5. Reboot your router:

Unplug for 1 minute, then restart.
