Home Assistant Connect ZBT-2
Nabu Casa's official Zigbee + Thread coordinator dongle for Home Assistant. Plugged into panda, serves as the primary Zigbee and Thread border router for the smart home.
Overview
| Field | Value |
|---|---|
| Manufacturer | Nabu Casa |
| Model | Home Assistant Connect ZBT-2 |
| Serial | E072A1DC134C |
| Host | panda (plugged into USB) |
| Protocols | Zigbee 3.0 + Thread (IEEE 802.15.4) |
| HA Integration | ZHA (Zigbee) + Thread (OpenThread Border Router) |
Role in the Smart Home
The Connect ZBT-2 is the primary coordinator for all Zigbee and Thread devices in the home. It provides:
- Zigbee Coordinator — via ZHA integration, manages the Zigbee mesh network
- Thread Border Router — via Thread integration, provides IP connectivity for Thread devices
- Matter Controller — via Matter integration, commissions and controls Matter devices over Thread
Zigbee Devices (via ZHA)
All Zigbee devices are paired directly to the Connect ZBT-2 coordinator:

Thread Network
The Connect ZBT-2 runs an OpenThread Border Router, creating a Thread network that:
- Provides IP connectivity to Thread-only devices
- Acts as a Matter fabric gateway
- Shares Thread credentials with other border routers (e.g., Apple TV, Nest Hub) for mesh redundancy
Multi-Fabric Position
In the matter-multi-fabric architecture, the ZBT-2 serves as:
- HA's Matter fabric controller — primary commissioning point for new Matter devices
- Thread credential source — other border routers should join this Thread network
- Zigbee bridge — exposes Zigbee devices to Matter via HA's Matter Bridge feature
Relationships
- Connected to panda via USB
- Controls all Zigbee devices in the home
- Provides Thread connectivity for matter-multi-fabric
- Complements aqara-hub-m3 (which bridges Aqara-specific devices via Matter)
Notes
- Thread credentials should be shared with aqara-hub-m3 and Apple TV to ensure a single unified Thread mesh
- If adding more Thread border routers, export credentials from this OTBR and import them
- The ZBT-2 is a dual-protocol radio — Zigbee and Thread cannot run simultaneously on the same radio; HAOS handles multiplexing
