Follow this guide if you have a Zigbee2MQTT network running and want to migrate to Home Assistant Connect ZBT-1 and Zigbee Home Automation (ZHA).

Note: this procedure only helps migrate basic network settings to your Home Assistant Connect ZBT-1.

• Customizations like device names will be lost and automations will need to be updated.
• Most powered devices like lightbulbs will be re-discovered over time (you can speed this up by rebooting the device) but your battery-powered devices may need to be re-joined to the network for the migration to complete.

There is currently no migration path to migrate all settings and devices.

If you no longer have the old stick, you can migrate via a Zigbee2MQTT backup.

To migrate a Zigbee2MQTT network to ZHA

Step 1

Stopping the Zigbee2MQTT add-on

• Under Settings > Add-ons, in the Zigbee2MQTT add-on, select Stop.
• Zigbee2MQTT uses the MQTT discovery feature to make the Zigbee devices available in Home Assistant. After removing the Zigbee2MQTT add-on, the devices are still present in Home Assistant since the MQTT broker is still holding on to the MQTT discovery messages.
• It is recommended to remove these stale devices from the MQTT broker (see next steps).

Step 2

Removing Zigbee2MQTT devices (option 1)

• If you don't use MQTT outside of Zigbee2MQTT, you can delete the Mosquitto Broker integration.
  1. Under Settings > Devices & services, select the Mosquitto broker integration.
  2. Select the three dots and in the dropdown menu, select Delete.

Step 3

Removing Zigbee2MQTT devices (option 2)

• If you don't want to delete the Mosquitto Broker integration, you can remove the devices from the MQTT network.
  1. In the integration card, select Devices, under Device info, select Delete.
  2. Repeat this for every device.

Step 4

Adding the ZHA integration (1)

1. Under Settings > Devices & services, if you do not see the ZHA integration, select the Add integration button.
2. From the dropdown list, select Add Zigbee device.

Step 5

Adding the ZHA integration (2).

1. Make sure your old radio stick is still plugged in.
2. Select Proceed.

Step 6

Adding the ZHA integration (3)

1. Choose the serial device path of your old radio stick.
2. Select Submit.

Step 7

Choosing the network settings for your radio

• Select Keep radio network settings.
• Result:

  You can now start migrating the ZHA network as described below.

To migrate an existing ZHA network to Connect ZBT-1

Step 1

Starting radio migration

1. Under Settings > Devices & services, select the ZHA integration, then select Configure.
2. Under Network settings add-on, select Migrate Radio.

Step 2

Reconfiguring ZHA

• To reconfigure ZHA, select Submit

Step 3

Migrating radio

• Select Migrate to a new radio

Step 4

Starting the backup

• To start automatic backup, select Submit.

Step 5

Unplugging the old radio

• If you no longer need the old radio stick, you can now remove it.
• Before selecting Submit, connect Connect ZBT-1, as described in the following steps.

Step 6

Adding extension cable

Notice

USB 3.0 ports and USB 3.0 drives can cause interference with 2.4 GHz protocols, including the ones provided by Home Assistant Connect ZBT-1.

- It is important to use the USB extension cable and to position the Home Assistant Connect ZBT-1 away from possible interference sources.

- This video shows the effect of interference.

• Plug the Home Assistant Connect ZBT-1 into the USB extension cable.
• Plug the extension cable into your Home Assistant instance.
• If you are using the standalone Home Assistant Container installation method, make sure Connect ZBT-1 is mapped to the container.

Step 7

Confirming that Home Assistant Connect ZBT-1 is plugged in

• Now that Home Assistant Connect ZBT-1 is plugged in, select Submit.

Step 8

Choosing the port

• Choose the serial port with Connect ZBT-1 and select Submit.

Step 9

Restoring a backup

• Select Restore an automatic backup.

Step 10

Choosing the backup

• Choose the latest backup and select Submit.

Step 11

Overwriting the radio IEEE address

• Select the Permanently replace the radio IEEE address and select Submit.
• Info This means that your old stick and your new stick will have the same IEEE address.
  • This is required for the migration process to complete successfully.
  • From this point onwards, you should not operate the old stick in the same area. If you do not migrate the IEEE address from your old stick, you'll have to repair many of your devices to keep them working.

Step 12

Wait

• Overwriting the IEEE address may take a while. Wait.

Step 13

Migration complete!

• Select Finish to confirm. The migration process is now complete.
• Info 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.
