This guide assumes you have already completed the following step:

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

• Multiprotocol is an experimental feature. It may not work for you.
• When multiprotocol support is enabled, the Home Assistant Yellow's IEEE 802.15.4 radio can be used for both Zigbee and Thread (used by Matter) at the same time. The two networks will be running on the same IEEE 802.15.4 channel.
• If the radio is already used by the ZHA Zigbee integration, ZHA will be automatically reconfigured to use the multiprotocol firmware. Your Zigbee network will continue to work.

1. Go to Settings > System > Hardware.
2. Under Home Assistant Yellow, select Configure.
3. Select the Configure IEEE 802.15.4 radio multiprotocol support option.
4. Select the Enable multiprotocol support checkbox and select Submit.

• Wait for the installation of the Silicon Labs Multiprotocol add-on to complete.

• Once the installation is complete, select Finish.

• Go to Settings > Devices & Services.
• You should now see the Open Thread Border Router integration.
• Select the ZHA integration. You should now see the Yellow Multi-PAN label.

• Thread support is still under development. For information on Thread, refer to the documentation of the Thread integration.
• Select the Thread integration. Then select Configure.
• You should now see your Home Assistant border router.
