Direct answer: pick the integration before the USB stick
Choose ZHA or Zigbee2MQTT first, then check the exact
coordinator against that project's supported hardware list.
ZHA uses Home Assistant's Zigbee integration and the zigpy driver
family. Zigbee2MQTT runs its own gateway and needs a supported
adapter, coordinator firmware, an MQTT broker and Home Assistant
discovery. The same radio chip name does not prove that every
firmware and setup combination is supported.

support or independently test installations.
ZHA versus Zigbee2MQTT: what to verify
| Check | ZHA |
Zigbee2MQTT |
|---|
| Adapter support | Check supported zigpy/ZHA radio
hardware | Check Zigbee2MQTT's adapter-specific list |
| Firmware | Compatible Zigbee coordinator firmware
for the selected adapter | Correct coordinator firmware
and required adapter configuration |
| Gateway software | Home Assistant ZHA integration
| Zigbee2MQTT plus MQTT broker and HA discovery |
| Existing network | Use ZHA-supported migration or
backup process | Follow Zigbee2MQTT's specific adapter
migration guidance; re-pairing may be necessary |
| Model evidence | ZHA documentation and any relevant
quirks | Exact Zigbee2MQTT supported-device page and
reported exposes |

Zigbee and Thread are not interchangeable radio modes
For example, Home Assistant documents that its
Connect ZBT-2 can be dedicated to
either Zigbee or Thread, but not both at once.
Matter-over-Thread needs a suitable Thread network and border
router. It is not made compatible by selecting a Zigbee2MQTT
coordinator. Do not infer universal multiprotocol operation from
an adapter supporting multiple radio standards in its specifications.
Five checks before buying or replacing a coordinator
- Identify the integration you will actually run (ZHA,
Zigbee2MQTT, or Thread/Matter). Save the existing network's
backup and software details before changing adapters.
- Find the exact adapter product identifier and chipset in
the chosen integration's current supported hardware list.
- Read the required coordinator firmware and transport details.
Zigbee2MQTT warns that some Wi-Fi-connected adapters may be less
reliable than wired Ethernet or locally connected alternatives.
- Review network migration and re-pairing requirements. A
software change does not automatically migrate an existing mesh.
- Check placement, USB interference, available USB ports,
update support and the return policy. Never assume range or
a precise device count from a chipset name alone.
