The SONOFF Dongle Plus CC2674P10 (Dongle-PP10) is a USB Zigbee 3.0 and Thread radio adapter designed primarily for Home Assistant and other open-source smart home systems. When connected to a computer, mini PC, or other host device, it can be used as a Zigbee coordinator, Zigbee router, or OpenThread RCP adapter, depending on the installed firmware.
The Dongle-PP10 is equipped with a Texas Instruments CC2674P10 system-on-chip, 1024 kB of flash memory, 256 kB of RAM, and a 48 MHz Arm Cortex-M33 processor. The radio provides transmit power of up to +20 dBm, while the external antenna has a nominal gain of 3 dBi. The manufacturer specifies a communication range of up to 200 metres under line-of-sight conditions.
The device is supplied from the factory with Z-Stack-based Zigbee coordinator firmware, allowing it to be used as a Zigbee adapter for systems such as Zigbee2MQTT or ZHA. Using the SONOFF Dongle Flasher, Zigbee router or OpenThread RCP firmware can also be installed. In the latter case, it can serve as the radio interface for a system running an OpenThread Border Router service for Thread and Matter over Thread devices. Because Zigbee and Thread use the same radio, the Dongle-PP10 can perform only the radio role corresponding to the currently installed firmware at any given time.
The Dongle-PP10 is an upgraded version of the previous ZBDongle-P. Instead of the CC2652P, it uses the newer CC2674P10 system-on-chip, with significantly increased flash memory and RAM capacity, a more powerful processor, and native Thread support. The enclosure has also been made more compact, making the adapter easier to use alongside other USB ports.

Key Product Features
- CC2674P10 system-on-chip: Equipped with 1024 kB of flash memory, 256 kB of RAM, and a 48 MHz Arm Cortex-M33 processor.
- Multiple radio roles: Depending on the installed firmware, it can be used as a Zigbee coordinator, Zigbee router, or OpenThread RCP adapter.
- Factory-installed Zigbee coordinator firmware: The Dongle-PP10 is supplied with Z-Stack-based coordinator firmware, allowing it to create a Zigbee network and manage compatible Zigbee devices.
- Up to +20 dBm transmit power: High radio transmit power and the external antenna help support larger Zigbee or Thread networks.
- External antenna: The antenna has a nominal gain of 3 dBi. According to the manufacturer, optimising antenna orientation and the radio channel can provide gain of up to 4.5 dBi.
- 200-metre communication range: The manufacturer specifies a signal transmission range of up to 200 metres under line-of-sight conditions.
- USB extension cable: The included 1-metre USB extension cable allows the adapter to be positioned farther away from the computer or SBC, helping to reduce radio interference.
- Aluminium alloy enclosure: The compact metal housing provides a durable enclosure for the adapter.
- TrustZone hardware security: The CC2674P10 system-on-chip supports Arm TrustZone hardware security technology.
Smart Home Protocols and Platform Compatibility
- Zigbee 3.0: With the appropriate firmware, it can be used as a Zigbee network coordinator or router.
- Thread: With OpenThread RCP firmware, it can be used as the radio interface of a Thread network.
- Matter over Thread: With OpenThread RCP firmware and a host running OTBR, a Thread network suitable for connecting Matter over Thread devices can be created.
- Home Assistant: Can be used as a Zigbee coordinator with ZHA or Zigbee2MQTT, or as a Thread RCP adapter alongside OpenThread Border Router.
- Zigbee2MQTT: The CC2674P10-based Dongle-PP10 can be used as a supported Texas Instruments Z-Stack adapter.
- ZHA: With the factory Zigbee coordinator firmware, it can be connected to the Home Assistant Zigbee Home Automation integration.
- OpenThread Border Router: With OpenThread RCP firmware, it can be used as the radio adapter for the OTBR service.
- MQTT: When used with Zigbee2MQTT, Zigbee device data and control can be integrated with other systems through MQTT.
- eWeLink CUBE: The adapter can also be used with eWeLink CUBE OS to manage Zigbee devices and bridge compatible devices to Matter systems.
- Other open-source systems: Compatibility primarily depends on whether the particular system supports Texas Instruments Zigbee adapters. The manufacturer provides compatibility information for systems including Home Assistant, Zigbee2MQTT, ioBroker, Domoticz, and openHAB.
