If you want a smart home that runs locally, without depending on a dozen different cloud apps, Zigbee is one of the best foundations, and the SONOFF Zigbee 3.0 USB Dongle Plus (ZBDongle-P) is one of the most popular ways to add it to Home Assistant. It plugs into USB, uses a proven Texas Instruments CC2652P chip and works with both ZHA and Zigbee2MQTT.

Here is what it does, how it compares with the ZBDongle-E, and how to get the most out of it.

Note: this review is based on SONOFF’s official specifications, the AliExpress listing and community documentation. We have not run our own lab measurements.

Quick Verdict

Best for: Home Assistant users and DIY smart home fans who want a reliable, affordable Zigbee coordinator for sensors, plugs, lights and switches from many brands.

Skip it if: you do not run Home Assistant or another self-hosted platform. For an app-only setup, a brand hub is simpler.

SONOFF ZBDongle-P Specifications

Why a Zigbee Dongle?

Zigbee devices such as door sensors, motion sensors, buttons, smart plugs and bulbs use very little power and form a mesh network, where mains-powered devices relay signals for others. A USB coordinator like the ZBDongle-P turns your Home Assistant server into the hub for all of them, from many different manufacturers, with automations that keep working even if your internet goes down.

Performance and Range

The CC2652P is a well-established Zigbee chip with a built-in power amplifier, and SONOFF rates the dongle at +20 dBm transmit power. Combined with the external antenna and aluminum enclosure, that gives it strong range for a USB stick. In a real home, range depends heavily on walls and on having mains-powered Zigbee devices acting as routers.

Setup Tips

• Use a USB extension cable. USB 3.0 ports and SSDs can cause 2.4 GHz interference. Putting the dongle on a short extension cable away from the computer is the most common fix, and the listing offers a bundle with one.
• Choose ZHA or Zigbee2MQTT. ZHA is built into Home Assistant and is simplest. Zigbee2MQTT offers broader device support and finer control. Both work with this dongle.
• One ZHA coordinator. Home Assistant supports a single ZHA integration, so plan your network around one coordinator.
• Add routers early. Pair a few mains-powered devices first to build a strong mesh before adding battery sensors.

ZBDongle-P vs ZBDongle-E

SONOFF sells two similar sticks. The ZBDongle-P uses the TI CC2652P chip and is long established with Z-Stack firmware and strong Zigbee2MQTT support. The ZBDongle-E uses a Silicon Labs EFR32MG21 chip and, according to SONOFF, adds support for openHAB. For most Home Assistant users, either works; the P is a safe, well-documented choice.
