Troubleshooting

Controller didn’t connect to Wi-Fi:

If unsuccessful in the first attempt to connect the controller to the Wi-Fi network, hold down the Setup button located on the controller (see page 16) for approximately 12-15 seconds until there is a rapid flashing blue light. Once rapid flashing becomes visible, immediately release the Setup button. This will put the controller into Listening Mode (Blinking Blue). Now, restart the connection process outlined on page 7.

The Wi-Fi network being used has changed:

In the event the controller needs to re-connect to an existing or new Wi-Fi network, put the controller back into Listening Mode (see above) and follow the Controller Connection process outlined on page 7.

pH values are not as expected or do not match with 3rd party measuring device:

Recalibrate pH and EC Probes (see page 16). To ensure accuracy, recalibrate 3rd party measuring device using the same buffer solutions used to calibrate the Smart Water Wireless 2 probes.

Controller LED status light color codes

During initial set up of a device and operation, these are the usual LED specifications:

• White Pulse: Start-up.
• Flashing Blue: Listening Mode, waiting for Wi-Fi credentials.
• Flashing Green: Connecting to Wi-Fi network (if flashing green occurs after the controller has been previously connected, this means the connection has been lost, or the network may have gone offline).
• Breathing Green: Connected to Wi-Fi network.
• Blinking Green/Rapid Flashing Cyan: If controller is not reachable from the Growlink app or Portal, this could mean there is a weak/lost connection to the local network. Check connection and/or move Wi-Fi access point closer to controller.
• Flashing Cyan: Connecting to Growlink Device Cloud (connecting to the network, but not necessarily connected to the internet yet).
• High-speed Flashing Cyan: Growlink Device Cloud handshake.
• Breathing Cyan: Connected to Growlink Device Cloud.
• Flashing Magenta: Receiving new firmware update over-the-air (OTA).
• Breathing Magenta: Safe Mode, connected to Particle Device Cloud, but user firmware not running.
