Overview
The Sonoff Zigbee 3.0 USB Dongle Plus (model ZBDongle-P) has become one of the most popular Zigbee coordinators for Home Assistant users, and for good reason. It's affordable, widely compatible, and uses the well-regarded Texas Instruments CC2652P chipset — the same chip trusted by the Zigbee2MQTT community for years.
If you're building a local smart home with Zigbee devices and want to ditch proprietary hubs, this dongle is one of the first purchases you should make. At under $25, it represents exceptional value for what it delivers.
Sonoff Zigbee 3.0 USB Dongle Plus (ZBDongle-P)
Texas Instruments CC2652P chipset, up to 200+ devices, works with Zigbee2MQTT and ZHA. The go-to Zigbee coordinator for Home Assistant.
Check Price on AmazonSpecs & Hardware
The ZBDongle-P is built around the Texas Instruments CC2652P SoC, which includes an integrated power amplifier for extended range. Key specs:
- Chipset: TI CC2652P (with PA/LNA)
- Protocol: Zigbee 3.0
- Frequency: 2.4 GHz
- Max devices: 200+ (coordinator mode)
- Interface: USB-A
- Antenna: External antenna (SMA connector)
- Firmware: Z-Stack 3.x (flashable)
The physical design is a standard USB stick with a small stub antenna attached to an SMA connector. The antenna is removable, so you can upgrade to a higher-gain antenna if needed. The included antenna is already significantly better than the PCB antennas on many competing dongles.
One important note: there are two versions of this dongle — the ZBDongle-P (CC2652P, the one we recommend) and the ZBDongle-E (EFR32MG21 chipset). Both work well, but the P version has broader community support and more mature firmware.
Setup with Zigbee2MQTT
There are two main ways to use this dongle with Home Assistant: Zigbee Home Automation (ZHA) — the built-in HA integration — or Zigbee2MQTT — a more powerful third-party solution. We recommend Zigbee2MQTT for most users due to its broader device support and more detailed device information.
Step 1: Install the Zigbee2MQTT Add-on
Add the Zigbee2MQTT add-on repository to Home Assistant, install it, and configure the serial port. The dongle will typically appear as /dev/ttyUSB0 or /dev/serial/by-id/usb-ITead_Sonoff_Zigbee_3.0_USB_Dongle_Plus.... Use the by-id path to avoid issues if other USB devices are connected.
Step 2: Use a USB Extension Cable
This is the most important tip for Zigbee performance: always use a USB extension cable (15–30cm) to move the dongle away from the USB port. USB 3.0 ports generate interference in the 2.4 GHz band that can severely degrade Zigbee range. A cheap USB 2.0 extension cable solves this entirely.
Range & Stability
With the external antenna and the CC2652P's power amplifier, range is the ZBDongle-P's strong suit. In testing, we achieved reliable communication over 15 meters through two interior walls — noticeably better than dongles without a PA (like the CC2530-based sticks).
Long-term stability is excellent. Running with 40+ Zigbee devices in a mixed environment (bulbs, sensors, plugs), the dongle ran for over eight months without a single restart required. The mesh network self-heals reliably when a device goes offline.
Device Compatibility
The CC2652P chipset is compatible with virtually every Zigbee 3.0 device, and many older Zigbee HA/LL devices as well. In our testing, the following devices paired flawlessly:
- IKEA TRÅDFRI bulbs and sensors
- Aqara motion, door/window, and temperature sensors
- Philips Hue bulbs (without the Hue Bridge)
- Sonoff ZBMINI switches
- TUYA Zigbee devices (with varying levels of support)
- Xiaomi/Mi smart home devices
- Third Reality sensors
The Zigbee2MQTT supported devices list contains over 3,000 devices, and the overwhelming majority work perfectly with this dongle.

Verdict
Our Verdict: Best Value Zigbee Coordinator
The Sonoff ZBDongle-P is our top pick for most Home Assistant users building a Zigbee network. It delivers excellent range thanks to the CC2652P's power amplifier, long-term stability, broad device compatibility, and superb community support — all for around $20. The only scenario where we'd recommend something else is if you also need Z-Wave support (consider the HUSBZB-1 instead).
For anyone starting fresh with Zigbee + Home Assistant, this is the dongle to buy.
