Echo 4th gen Zigbee hub

You probably do not want a “hub” but instead a “Zigbee Coordinator” for use with ZHA or Zigbee2MQTT:

or

https://www.zigbee2mqtt.io (Zigbee2MQTT, a.k.a. Z2M deoends on MQTT MQTT - Home Assistant )

Tip! Both works great (though not at the same time) with Texas Instruments based Zigbee Coordinator:
