This guide assumes you have the following setup:

• Connected Home Assistant Connect ZBT-1.
• Home Assistant OS installation.
• Multiprotocol support disabled: Refer to the Disable multiprotocol support procedure.
• This guide installs a firmware which supports only Thread! If you use your Connect ZBT-1 to control Zigbee devices, you will no longer be able to control them after installing the Thread firmware.
• Home Assistant Supervised: The Thread border router has some specific requirements on IPv6 configuration (for example, IPv6 routing needs to be enabled). The add-on is being tested on the Home Assistant OS. If you experience connectivity issues, try using a Home Assistant OS installation.

• If you have a new Connect ZBT-1 or did not setup Zigbee Home Automation (ZHA) yet, skip to Step 2.
• If you use your existing Connect ZBT-1 to run a Zigbee network, Migrate your Zigbee network to another controller.
  • Otherwise, if you delete the Zigbee network, even if you set it up again, all of your entity customizations will be gone.
• If you are using the Connect ZBT-1 with Zigbee Home Automation (ZHA), and you no longer need a Zigbee network, follow these steps to remove ZHA from the integration list.

1. Go to Settings > Devices & services.
2. Select the Zigbee Home Automation integration card.
3. Select the menu behind the Connect ZBT-1 v1.0 integration and choose Delete.
4. On the pop-up menu, select Delete again to confirm deletion.

1. Go to Settings > System > Hardware.
2. Under Home Assistant Connect ZBT-1, select Configure.

1. Select Use as a Thread border router.
• Result: This will install the OpenThread Border Router add-on.
2. The dialog informs you that Connect ZBT-1 now acts as an OpenThread border bouter. Select Submit.
3. Then, select Finish.

• Go to Settings > Devices & services.
• You should now see the OpenThread Border Router and the Thread integrations.
• If you don't see the Thread integration, install it.
