Quick verdict

The ZBT-2 is Nabu Casa's successor to the ZBT-1, a first-party USB stick that can run either a Zigbee or a Thread network with native Home Assistant support. It uses a newer, more powerful radio than the ZBT-1. Like any coordinator it runs one radio role at a time and benefits from a USB extension cable, but as the least-drama first-party option it is an easy recommendation.

Standout: First-party Zigbee and Thread coordinator built on the EFR32MG24, the successor to the ZBT-1.

Why it stands out

  • first-party Nabu Casa hardware with native Home Assistant support for both Zigbee and Thread
  • newer, more powerful EFR32MG24 radio than the ZBT-1
  • runs either a Zigbee or a Thread network, both fully local

Reasons to hesitate

  • runs one radio role at a time: Zigbee or Thread, not both simultaneously
  • USB placement (use an extension cable away from USB 3.0 ports) matters for performance
  • a coordinator alone cannot fix poor mesh planning in large homes

Best for

  • Home Assistant users building a new local-first Zigbee or Thread network
  • ZBT-1 owners wanting a more capable first-party coordinator

Avoid if

  • you specifically need an Ethernet-attached coordinator for placement flexibility
  • you want to run Zigbee and Thread simultaneously on one stick

Privacy and local-control notes

Buying reality check
