This guide assumes you have already completed the following steps:

• Have the Zigbee Home Automation (ZHA) integration up and running.
• Enabled multiprotocol support

• To disable the multiprotocol feature and use Yellow for Zigbee only, make sure to follow all the steps in this procedure.

• Go to Settings > Add-ons, and in the Silicon Labs Multiprotocol add-on, select Uninstall.

• Delete the Open Thread Border Router integration.

1. You can update the firmware of the Silicon Labs radio firmware to work with Zigbee only. Go to Settings > Add-ons, and install the Silicon Labs Flasher add-on.
2. Make sure the Start on boot and the Auto update options are disabled.
3. In the Configuration tab, select the serial port ttyAMA1 and save the changes.
4. To observe the flashing process, open the Logs tab in a separate window.
5. On the Info tab, start the Silicon Labs Flasher.
6. Wait for the flashing process to complete. This may take a while. To view the progress, in the Logs tab, select Refresh.
   • When you reload the add-on UI (Ctrl+Shift+R), the dot on the top right should have changed from green to red. If it is still green, the process is not finished.
7. Once you see the red dot, the flashing process is complete. Continue with the next step.

• Yellow is now setup in the non-multiprotocol ZHA integration, although the title still includes Multi-PAN.

1. Click the three-dot dropdown menu on the Zigbee Home Automation (ZHA) integration and select Rename.
2. Remove Multi-PAN from the name of the integration.

• On the Zigbee Home Automation (ZHA) integration, select Configure.
• Under Network Settings, select Migrate radio.

• Select submit.

• Select Re-configure the current radio.

• Select the path with Yellow.

• Select Restore an automatic backup.

• Choose the latest backup and select Submit.

• Select Finish to confirm. The migration process is now complete.
• You won't be able to control the devices until they rejoin the network. Normally, they rejoin within one hour. You may be able to accelerate that process by power-cycling devices.
