Hi Chris,
Welcome here. The ZBT-2 can not be connected with Homey, Homey is designed to use its own radio’s and offers no support for external devices as its radios or antennas.
That said, there’s a workaround when you don’t want to use Homey’s internal radios: Since you have Home Assistant you could run Zigbee2MQTT on it and import the Zigbee devices with the [APP][Pro] Zigbee2MQTT - Use Zigbee devices via MQTT app by Robin Gruijter.
That way your Home Assistant handles the Zigbee part of things and you can use Homey as the logic controller for your automations.
