Quick verdict
The ConBee III carries forward a long and proven track record in the Zigbee coordinator space. Firmware-switchable Thread support is a nice future option. Just remember you can't run both at once, so pick Zigbee or Thread, not both simultaneously.
Standout: Versatile Zigbee/Thread coordinator with support for ZHA, deCONZ, and zigbee2mqtt.

Local control facts
Home Assistant: zha integration, Local Polling (home-assistant.io, checked Oct 10, 2026)
Why it stands out
supports Zigbee and Thread with firmware switching
long track record, as the ConBee line is well-proven in the community
works with ZHA, deCONZ, and zigbee2mqtt for flexible integration
Reasons to hesitate
cannot run Zigbee and Thread simultaneously
deCONZ add-on can be heavier than ZHA for some setups
no external antenna, with similar range limitations to other compact USB coordinators
Best for
experienced Home Assistant users who want integration flexibility
deCONZ fans upgrading from ConBee II
Avoid if
you want the simplest possible setup. The first-party Home Assistant Connect ZBT-2 may be easier for beginners
you need simultaneous Zigbee and Thread on one stick
