SONOFF Zigbee 3.0 USB Dongle Plus Gateway - Universal Zigbee USB

Our review of the SONOFF Zigbee 3.0 USB Dongle Plus Gateway finds it best suited for smart home tinkerers and Home Assistant users who want a reliable, long-range coordinator without fuss. The dongle ships pre-flashed with Z-Stack 3.x.0 coordinator firmware, making setup far quicker for those using ZHA or Zigbee2MQTT. For anyone running Home Assistant on a Raspberry Pi or a small server, the combination of the TI CC2652P chipset and the external SMA antenna delivers a noticeable improvement in real-world range and stability compared with basic USB sticks.

Key Features

• Pre-flashed coordinator: Arrives ready with Z-Stack 3.x.0 firmware so most users can connect it to Home Assistant or Zigbee2MQTT without manual firmware steps.
• Strong radio platform: Based on the TI CC2652P chipset, it provides robust Zigbee 3.0 support and better device handling in larger mesh networks.
• External antenna: SMA interface allows placement of the included antenna for improved signal and greater range through walls and floors.
• Higher transmit power: +20dBm output gain helps reach devices at longer distances or through more obstructions than lower-power adapters.
• Aluminum housing: Metal enclosure reduces interference from nearby USB peripherals and helps maintain a stable connection.
• Compatibility options: Works with ZHA in Home Assistant or with Zigbee2MQTT, giving flexibility for different automation setups.

Who It's For

This dongle is aimed at DIY smart home builders, Home Assistant users, and integrators who need a dependable Zigbee coordinator with extended range and the option to use Zigbee2MQTT. People who value compatibility and easy initial setup will appreciate the pre-flashed firmware and the clear installation instructions provided via QR code.

Less experienced users who do not want to interact with Home Assistant or any local hub software may find a plug-and-play consumer hub easier; however, the manufacturer includes detailed tutorials to help new users of the ZBDongle-P follow the specific installation steps.
