Zigbee/Thread USB coordinators

Sonoff Z-Wave 800 Dongle Plus PZG23 USB coordinator for Home Assistant

Works with Z-Wave JS in Home Assistant and openHAB: an 800-series EFR32ZG23 USB coordinator with S2 Security and Z-Wave Long Range up to 1000 m line of sight.

Sonoff Dongle Plus MG24 Zigbee/Thread USB coordinator (Dongle-PMG24)

If your mesh keeps growing, the EFR32MG24 with 1536 KB Flash and 256 KB RAM keeps up — and a reflash turns the dongle into a Thread or Matter radio.

The 43 mm body with its tilting antenna takes just one server USB port, and the bundled 0.5 m extension keeps the coordinator radio clear of USB 3.0 noise.

Dozens of Zigbee devices in Zigbee2MQTT or ZHA on a single stick: the TI CC2652P coordinator with +20 dBm output holds up to 200 nodes and reflashes into a router.

Unlike the ZBDongle-P built on the TI CC2652P, revision E runs a Silicon Labs EFR32MG21 with EmberZNet (EZSP) firmware, 20 dBm out of the box and Thread potential.

For Zigbee2MQTT experiments and a small network of up to ~20 devices this legacy CC2531 dongle still does the job — no external antenna, firmware updates need a programmer.
