Communication Symptoms 

Symptom: 

• Inability to upgrade firmware, activate devices, or transfer the database/project. 

• The software does not discover the processor in the activation/transfer tab. 

Causes and Actions:  

• Managed networking switches preventing reliable communication. Contact the network administrator to allow communication; bypass managed switch and connect directly to the primary network or unmanaged switch. 

• Firewalls or other data relegating/blocking software. On the PC, disable any related forms of firewalls, antivirus, and malware protection. 

• RA3 processor and PC are on different networks. Check to see what IP the processor is on via LAN or a network scan. Then check the PC network properties to see what IP it is on. Ensure the first 3 octets (ex 192.168.0.xx) are matching. 

• Static IP is set incorrectly under standard and advanced settings. Verify set IP credentials or revert to DHCP in the activation tab. 

Symptom: 

• The processor and software are on different firmware versions.  

Causes and Actions:  

• An update was performed to only one of two required items. Check for updates via Designer settings- Upgrade processor via Designer settings. 

Symptom:  

• Lutron app does not show access to the project file/project name does not appear under the PRO installer account. 

Cause and Actions:  

• The PRO account in use does not currently have access to the file. Have the original installer share access, or have the homeowner go into their Lutron App < Settings < Help < Get remote assistance from installer < have them enter your PRO credentials to share access. Once given access, refresh the app and software to update accessed projects. The Designer “restore last transferred file” feature will always show current system access.  

• The app in use is the Incorrect App. Ensure the app in use is the “Lutron App”. 

Symptom: 

• Software shows processor is “already activated in another project”. 

Cause and Actions: 

• The project file in use is not the most recently transferred cloud-enabled project.  Select “tools” in the Designer RA3 main menu. Then select “restore last transferred file” and load the most recent cloud project. 

Symptom: 

• Transfer completes with device failures or warnings. 

Cause and Action: 

• RF Range issues. Ensure all devices are within the specified range of the device type. CCX devices have a maximum range of 75ft from the processor with 2 devices minimum every 25ft. CCA Devices must be placed within 30ft of the nearest processor or auxiliary repeater when placed in homes with standard construction/building material. 

• The device is not defaulted or has been paired to another device/system at some point.  Factory Reset the device. 

• The model number in the software does not match the physical device. Ensure device models are accurate in Design Tab. 

• Activation was not completed, the device was improperly programmed, or the transfer was not completed correctly. Factory Default related device/s, Delete from Design Tab, Full Transfer over the project (under advanced settings in transfer tab), Add device, re-activate the device, force full transfer to reapply device database. 

Symptom: 

• Linking the processor to a Lutron App account yields “cannot find processor”. 

Cause and Action: 

• The Lutron App device is on a separate Wi-Fi network from the processor. Cross-reference the IP the device is on in comparison to the IP the processor is on. The first 3 IP octets must be identical. Contact Lutron Tech Support for IP confirmation.
