Sonoff Dongle Plus CC2674P10 USB Adapter (Zigbee/Thread)

Product detailed description

Sonoff Dongle Plus CC2674P10 Zigbee coordinator and Thread adapter for a fully local smart home 

Sonoff Dongle-PP10 (Dongle Plus CC2674P10, also listed in shops as Dongle PP10) is a Zigbee and Thread USB adapter that turns your Home Assistant server, mini PC or Raspberry Pi into the hub of your whole smart home. Plug it into a USB port and it works out of the box as a Zigbee coordinator for ZHA and Zigbee2MQTT, so you control sensors, switches and bulbs from different brands locally, without the cloud and without depending on the manufacturer's app.

Compared to its popular predecessor ZBDongle-P, it brings the new Texas Instruments CC2674P10 chip with three times the memory, a more powerful processor, native Thread support and a more compact aluminium body that does not block neighbouring USB ports.  

The dongle is the core of open smart home platforms: it joins Zigbee or Thread devices of different categories and brands into one network, for example Sonoff, Aqara, IKEA, Philips Hue or Tuya. Instead of five different gateways from five brands, you only need one small USB stick and one system in which you set up and automate everything.

The adapter is ready to use right away with Home Assistant, Zigbee2MQTT and OpenThread Border Router (OTBR). If you don't have anything to run Home Assistant on yet, the ideal match is Home Assistant Green with a preinstalled system, into which you simply plug the dongle.

Under the aluminium housing runs a 48 MHz Arm Cortex-M33 processor with 1024 KB of flash and 256 KB of RAM. In practice, this Zigbee USB stick handles even a larger network with dozens of sensors and switches talking at the same time without hesitation. Arm TrustZone hardware security also improves resistance to attacks at chip level.

Range is provided by an adjustable external antenna (90° vertical, 180° horizontal) with 3 dBi gain, which rises to up to 4.5 dBi with proper orientation and channel selection. Together with transmit power of up to 20 dBm, the manufacturer states a range of up to 200 m in line of sight and better wall penetration.

The package includes a 1 m USB extension cable. This matters: USB 3.0 ports, SSD drives and the Raspberry Pi itself emit interference in the 2.4 GHz band, which is the most common cause of an unstable Zigbee network. Moving the dongle a little away from the computer makes the network noticeably more reliable.

The aluminium alloy body is light and compact, about 30 % smaller than the ZBDongle-P, so it does not cover neighbouring ports. The manufacturer verified its durability with a 24-hour salt spray test, 100 firmware flashing cycles, 20 electrostatic discharge tests and more than 500 USB insertions.

Its biggest advantage is flexibility. With one click in the web tool SONOFF Dongle Flasher you change the role the dongle plays in the network: Zigbee coordinator (preinstalled Z-Stack firmware), Zigbee router to extend the network, or Thread RCP to connect Matter over Thread devices via OTBR. If you build on Zigbee today and want to try Thread tomorrow, you don't need to buy new hardware.

You can flash firmware in three ways: via the web flasher in your browser, via Docker or directly as a Home Assistant add-on. The manufacturer also runs a dedicated site with guides and troubleshooting at dongle.sonoff.tech.

If you want to bring Zigbee devices into Apple Home, Google Home, Alexa or SmartThings, the dongle also works with the free local system eWeLink CUBE, which bridges Zigbee devices into the Matter network. You will find suitable devices in the categories Zigbee products and Matter Smart Home.

Who is the Sonoff Dongle-PP10 for

• For Home Assistant users who want a stable Zigbee coordinator for ZHA or Zigbee2MQTT.
• For owners of the older ZBDongle-P whose network has outgrown it and who want a more powerful successor with easy migration.
• For households with a mix of devices from different brands (Sonoff, Aqara, IKEA, Hue, Tuya) who want one shared gateway instead of several.
• For those who value privacy and want a cloud-free smart home.
• For enthusiasts who want to experiment with Thread and Matter through their own OpenThread Border Router.

Use cases 💡

• Zigbee coordinator for Home Assistant on Raspberry Pi: plug in the dongle via the extension cable, select the port in ZHA or Zigbee2MQTT and start pairing sensors.
• Replacing ZBDongle-P with a more powerful adapter: in ZHA you move the whole network by migration without re-pairing devices.
• Zigbee router for a distant part of the house: with router firmware and powered from a USB charger, it extends the network to the garage, basement or workshop.
• Thread network for Matter devices: with OpenThread RCP firmware and OTBR you connect Matter over Thread devices directly to Home Assistant.
• Local control without the cloud: automations for lights, heating and sensors keep running at home even during an internet outage.
• Zigbee devices in Apple Home: together with eWeLink CUBE you bridge Zigbee sensors and switches into Matter.

Key features

• CC2674P10 chip: flagship Zigbee/Thread chip from Texas Instruments with 1024 KB flash and 256 KB RAM.
• Three roles in one: Zigbee coordinator, Zigbee router or Thread RCP depending on the flashed firmware.
• Ready out of the box: preinstalled Z-Stack coordinator firmware, no flashing needed after unpacking.
• 20 dBm transmit power: strong signal for larger homes and better wall penetration.
• Adjustable antenna: 3 dBi gain, up to 4.5 dBi with optimal orientation.
• 1 m extension cable: included, moves the adapter away from USB 3.0 and SSD interference.
• Aluminium housing: durable, light and slim, does not block neighbouring ports.
• Arm TrustZone: hardware security built into the chip.
• Fully local operation: control without the cloud, fast response and privacy.

Technical specifications

Protocols and compatibility

• Zigbee 3.0 (IEEE 802.15.4): coordinator with Z-Stack firmware out of the box, Zigbee router after reflashing.
• Thread / Matter over Thread: works after flashing OpenThread RCP firmware and only together with a host running OpenThread Border Router (OTBR). The dongle always performs only one role at a time; Zigbee and Thread do not run simultaneously on a single unit.
• Home Assistant (ZHA): supported as a TI Z-Stack adapter. Home Assistant allows only one ZHA integration, so one dongle for ZHA.
• Zigbee2MQTT: supported as a zstack adapter type, also suitable for connecting to other systems via MQTT.
• Other systems: according to the manufacturer ioBroker, Domoticz, openHAB and other platforms supporting TI Zigbee adapters.
• eWeLink CUBE: a free local system that bridges Zigbee devices via Matter into Apple Home, Google Home, Alexa, SmartThings and Home Assistant.
• Devices: works with most Zigbee devices (Sonoff, Aqara, Philips Hue, IKEA, Tuya and more). Actual support depends on the platform used, not the dongle itself. Browse the selection in the category Zigbee Hubs & Gateways.
• Operating systems: Windows, Ubuntu, Raspberry Pi OS and Docker; the CP210x driver is built into Linux by default.

Why choose the Sonoff Dongle Plus CC2674P10

• Performance headroom for years: three times the memory of the ZBDongle-P means a stable network even with many devices.
• Future-ready: Zigbee today, Thread and Matter tomorrow, just change the firmware.
• Proven TI Z-Stack ecosystem: the same chip family as the popular ZBDongle-P, with easy migration in ZHA.
• Everything in the box: antenna and extension cable included, nothing else to buy.

If you prefer a Silicon Labs chip (EmberZNet firmware), choose the Sonoff Dongle Plus MG24. If you want to place the coordinator in the middle of the house away from the server and power it via a network cable, go for the Sonoff Dongle Max with PoE. The Dongle-PP10 is the best choice for everyone who wants to stay with the proven TI Z-Stack and get significantly more powerful hardware.
