WiFi Module Communication Error with the Controller
Sequence: Solid Red
Meaning: The WiFi module is not communicating with the controller. It is best to take the following actions to try to resolve this issue. If the first does not resolve the issue please continue trying the following steps.
- Remove and reinsert the WiFi module. Make sure none of the pins the module slides into are bent.
- Remove the WiFi module again and press the reset button on the controller (may require a pen), wait 3 seconds, then reinsert the WiFi module
- Reset the WiFi module. While plugged in, press and hold the button on the WiFi module for 5 seconds. The LED should turn Amber colored, and then red, followed by three green blinks, followed by red and green alternating (WiFi Hotspot). After this reset is complete it will be necessary to set up the WiFi module again in the Rain Bird App as if it was new. Delete any previous controllers from the app by pressing the trash can icon for that controller in the app.
- If none of the above steps resolve the issue please contact Rain Bird customer service to determine if the WiFi module and controller are under warranty for replacement.
Sequence: One Amber flash without button push
Meaning: The WiFi module has detected an error and is completing a self-reboot to resolve the error
