Sonoff Dongle Max CC2674P10 Review: A PoE Zigbee and Thread Coordinator for Home Assistant
The Sonoff Dongle Max CC2674P10 is a Zigbee and Thread coordinator for open smart home platforms, built on a TI CC2674P10 radio alongside an ESP32-S3R8 for networking. It can run from USB-C, Ethernet or PoE and be reflashed as a Zigbee coordinator, a Zigbee router or an OpenThread RCP, which makes it a flexible radio for Home Assistant and Zigbee2MQTT. The trade-off is a single 802.15.4 radio, so Zigbee and Thread are alternative roles rather than simultaneous networks.
- Home Assistant and Zigbee2MQTT setups
- Homes where the radio should sit away from the server over Ethernet or PoE
- Zigbee networks that may later move to Thread
- Adding remote USB dongles through USB passthrough
Pros
- Runs as a Zigbee coordinator on the TI CC2674P10 radio
- USB-C, Ethernet, 2.4 GHz Wi-Fi and PoE for flexible placement
- Two adjustable 5 dBi antennas with up to +20 dBm Zigbee output
- Built-in web console for status, logs and firmware switching
- USB passthrough exposes other SONOFF USB dongles over the network
- Can be reflashed as a Zigbee router or an OpenThread RCP
- Works with Home Assistant and Zigbee2MQTT
- Two year warranty
Cons
- One 802.15.4 radio, so Zigbee and Thread are alternative firmware roles, not simultaneous
- No built-in Z-Wave controller, only USB passthrough for a separate Z-Wave dongle
- No Bluetooth proxy
- 2.4 GHz Wi-Fi only
- Needs an open platform such as Home Assistant, not a plug-and-play consumer hub
Who is the Sonoff Dongle Max CC2674P10 for?
This is a coordinator dongle rather than a consumer gateway, so it fits people running an open platform such as Home Assistant, with ZHA or Zigbee2MQTT, or an OpenThread border router. Because it can be powered by USB-C, Ethernet or PoE, it also suits homes where the server sits in a cupboard or a rack and the Zigbee radio is better placed centrally or in a detached garage. It is not aimed at someone who wants a plug-and-play hub with its own app.
What the Sonoff Dongle Max CC2674P10 offers
The hardware pairs a Texas Instruments CC2674P10 for Zigbee with an ESP32-S3R8 for Wi-Fi and networking. It has an RJ45 Ethernet port with PoE, a USB-C port, 2.4 GHz Wi-Fi and two adjustable 5 dBi antennas, with Zigbee output up to +20 dBm and a stated range of 330 m in free line of sight. A built-in web console shows status, logs and firmware information and lets you switch firmware without a command line, and it supports WireGuard and Webhooks for remote deployment. USB passthrough lets a host such as a Raspberry Pi reach SONOFF Z-Wave or Thread USB dongles over the network as if they were PoE dongles. The body measures 169 x 32.5 x 22 mm, weighs 102 g and carries a two year warranty.
What to know before you buy
The CC2674P10 is a single 802.15.4 radio, so Zigbee Coordinator, Zigbee Router and OpenThread RCP are firmware roles you switch between, not networks that run at the same time. There is no built-in Z-Wave controller and no Bluetooth proxy, and the Wi-Fi radio is 2.4 GHz only. It is also not a plug-and-play consumer hub: it expects an open platform such as Home Assistant, ZHA or Zigbee2MQTT. Anyone who wants a radio that is always on and maintenance-free should weigh the firmware switching and the networking setup before choosing it.
Is the Sonoff Dongle Max CC2674P10 worth it?
For a Home Assistant or Zigbee2MQTT setup, the value is flexibility. USB-C, Ethernet, Wi-Fi and PoE cover most placement problems, the dual external antennas and the current TI silicon give strong range, and USB passthrough lets one networked dongle also expose other SONOFF USB dongles. The limits are honest ones: one radio, no Z-Wave controller, no Bluetooth proxy and a 2.4 GHz-only Wi-Fi link. If your server already sits in the right spot, a simpler USB stick may be enough; if you need the radio out of the rack, this dongle is built for exactly that.
Frequently asked questions
Does the Sonoff Dongle Max CC2674P10 work with Home Assistant and Zigbee2MQTT?
Yes. It runs Zigbee coordinator firmware on the CC2674P10 radio and is documented for Home Assistant, with ZHA or Zigbee2MQTT, and for an OpenThread border router.
Can it run Zigbee and Thread at the same time?
No. The CC2674P10 is a single 802.15.4 radio, so you switch firmware between Zigbee Coordinator, Zigbee Router and OpenThread RCP rather than running both protocols together.
How is the Sonoff Dongle Max CC2674P10 powered and connected?
It accepts 5V 1A over USB-C or 48V 0.25A over PoE, and can connect over USB-C, an RJ45 Ethernet port or 2.4 GHz Wi-Fi. Two adjustable 5 dBi antennas handle the Zigbee radio.
Does it work as a Thread border router?
It can run OpenThread RCP firmware for use with an OpenThread Border Router, so it can serve a Thread network when flashed for that role.
What is USB passthrough for?
USB passthrough lets a host such as a Raspberry Pi use SONOFF Z-Wave or Thread USB dongles remotely over the network as if they were PoE dongles, which avoids USB cable length limits.
Is the Sonoff Dongle Max CC2674P10 a Z-Wave controller?
No. It is a Zigbee and Thread dongle. It can expose a separate SONOFF Z-Wave USB dongle through USB passthrough, but it does not control Z-Wave devices on its own.
