Litter-Robot 4: Blue light bar with blue blinking WiFi (Connecting to WiFi)

IMPORTANT 

1. Make sure your unit is plugged in.
2. Make sure your Whisker app is up-to-date.
3. Make sure your firmware is up-to-date. If the app does not give you the option to update, you have the latest version.

Preparation

If Litter-Robot 4 displays a blue light bar with a blinking blue light adjacent to the Connect button, this indicates that the unit is attempting to connect to WiFi.

1. To reconnect your unit, unplug the power supply for 15 seconds, plug it back in, and power it on.
   

If your robot remains offline, or the Connect light remains blinking:

1. Re-enable the connection by short-pressing the Connect button for one second to turn the WiFi off. The Connect light will change to solid white.
2. If your unit was previously onboarded to the app:

   1. Wait 30 seconds to allow the robot to complete its WiFi reset.

      Note: If the Connect button is held too long and the Connect light starts blinking yellow, the robot has entered onboarding mode and forgotten its saved WiFi network. Open the app and follow the Update Network flow to reconnect.
      

   2. Then, short-press the Connect button again for one second to re-establish the connection.

   3. Wait for the Connect light to change from blinking blue to solid blue.
      

3. If your unit has never been onboarded to the app:

   1. Follow our Onboarding your Litter-Robot 4 instructions.

Successful: If your unit is online and displays a solid blue light bar, you've been successful.

Unsuccessful: If you are still seeing a blue light bar with a blue blinking light, please follow these troubleshooting steps.

Troubleshooting

Update Whisker app

If Litter-Robot doesn’t reconnect automatically, ensure you are using the latest version of the Whisker app.

1. Search for the Whisker app in the App Store or Google Play Store.
2. To download the Whisker app, tap the Get or Install button.
3. If the Whisker app is already installed and an update is available, update to the newest version by tapping the Update button.
4. If the Whisker app is up to date, tap the Open button.

Update network

Update your network to ensure the unit has the correct WiFi credentials.

1. Open the Whisker app
2. Select your Litter-Robot 4
   
3. Select the Settings gear in the top right corner
   
4. Select Update Network
    
5. Follow the steps listed within the app

Once the update is complete, your Litter-Robot should be ready for use.

If your unit is online and displays a solid blue light bar, you've been successful.

If your unit is not displaying a solid blue light bar, your Litter-Robot 4 may be having issues connecting to Whisker servers. You'll want to log into your router to confirm or change some settings.

Update router settings

Setup a guest network

Set up a 2.4 GHz guest network for IoT devices

• Prevents other wireless devices from communicating with one another, possibly causing interference.
• Allows flexibility to change specific network settings without upsetting the entire household.
• Follow your router manufacturer's instructions to set up a guest network.

IoT device security

Next, find the setting for IoT device security.

• Some routers require IoT device authorization to allow the device to have access to the internet.
• If your router has this setting, follow the steps to authorize the Litter-Robot 4 access to the internet.

MiMo or QOS

Now, find the setting labeled MiMo or QOS.

• MiMo and QOS options attempt to employ power-saving modes that may cause interference on WiFi devices.
• Disable MiMo and/or QOS on the router.

Firewall security

Lastly, find the settings for your firewall security.

• Some routers have overactive firewall security settings that will block access to the HTTPS ports 8443 or 443. These are secure ports and access is needed for your unit and the app to access AWS servers.
• Follow your router manufacturer's instructions to open the ports 443 or 8443.

Reconnect your unit

• To reconnect your unit, re-enable the connection by short-pressing the Connect button for one second to turn the WiFi off, indicated by a white Connect LED.
• Wait 30 seconds to allow the robot to complete its WiFi reset.
• Then, short-press the Connect button for one second to reestablish the connection.
• The Connect LED will begin flashing blue again but should change to solid blue after a few seconds.

Successful: If your unit is online and displays a solid blue light bar you've been successful.

Unsuccessful: If you are still seeing a blue light bar with a blue blinking light there's likely an issue with your router, network, or Litter-Robot.
