Troubleshooting Lutron Controller Internet Connection Issues

If you are unable to connect a Lutron controller to the internet, use the troubleshooting information below to restore connectivity.

Supported Lutron Controllers

• RadioRa2 Main Repeater
• HomeWorks QS Processor
• Caseta Wireless

Initial Considerations

• Verify the network setup and confirm which device the main repeater or smart bridge is plugged into.
• If it’s a managed system, consult with the network professional managing the network to confirm all settings meet Lutron requirements.
• If connected to a device other than the main router (e.g., an Ethernet switch), try connecting directly to the router to test for full connection.
• If only a local connection or no connection is available, contact Lutron support or a networking professional to verify correct network settings.

RadioRa2 and HomeWorks QS Considerations

Check the following settings in the Lutron programming software under Advanced Settings:

• Ensure Restrict Communications with Processor to Local LAN Only is disabled.
• Ensure Disable Alarm.com Integration is not checked.

New vs. Pre-existing Lutron Setup

For New Installations:

• Have a network professional verify that all network requirements are configured (e.g., subnet, subnet mask, default gateway, DNS settings).
• Contact Lutron for official networking requirements and configuration steps.

For Existing Systems:

• If the system previously worked, determine what has changed — new router, network credentials, or firewall settings.
• If commands are failing in the Lutron app, contact Lutron or a networking professional to review connectivity parameters.

Testing Remote Access

Test whether remote commands work through the Lutron app when the phone is connected via mobile data (not Wi-Fi). Lutron devices can operate locally without full internet access, but a full connection is required for Alarm.com integration.
