SONOFF ZBDongle-E (Zigbee 3.0 USB Dongle Plus-E) is a USB Zigbee coordinator with an EFR32MG21 chip, +20 dBm transmitter and external antenna. Designed for Home Assistant (ZHA), Zigbee2MQTT, openHAB and other local systems. 5 V USB power, aluminium housing.

Product description

Zigbee 3.0 USB coordinator | USB | 5VDC | EFR32MG21 | +20 dBm | black | SONOFF | ZBDongle-E Plus

SONOFF ZBDongle-E (Zigbee 3.0 USB Dongle Plus-E) is a USB Zigbee coordinator with a Silicon Labs EFR32MG21 chip and a +20 dBm transmitter. Plugged into a computer, Raspberry Pi or mini server, it turns Home Assistant, Zigbee2MQTT or another system into a local Zigbee hub without the cloud.

Key idea:
If you build your smart home on your own server, you do not need a closed vendor hub – a USB stick is enough. ZBDongle-E controls Zigbee devices from various brands locally, and the external antenna and aluminium housing ensure good coverage.

Chip
EFR32MG21, Cortex-M33

Transmit power
+20 dBm, external antenna

Power supply
5 V, max. 100 mA (USB)

Dimensions
75 × 25.5 × 13.5 mm

How it works

The stick is plugged into a USB port of a computer or Raspberry Pi (preferably via a USB extension cable, away from USB 3.0 interference). The system recognises it as a serial port via the CH9102F interface.

Home Assistant (ZHA), Zigbee2MQTT, openHAB, ioBroker or Domoticz use the stick as the Zigbee network coordinator: sensors, relays, switches and thermostats are paired with it.

The result: the Zigbee network is managed on a local server, automations work without internet, and devices can be chosen from various brands.

Why choose ZBDongle-E?
The EFR32MG21 chip with a +20 dBm transmitter and an external SMA antenna provides good coverage, and the stick can be reflashed to router mode to extend the Zigbee network.

Zigbee coordinator – a local Zigbee network in Home Assistant or another system.
Devices from various brands – SONOFF, Aqara, IKEA, Tuya and other Zigbee devices in one system.
Wide coverage – +20 dBm transmitter and external antenna.
Works without the cloud – automations run on the local server.
Router mode – after reflashing, the stick can extend the Zigbee network.
Compact USB format – plugs into a computer, Raspberry Pi or NAS.

Where is it used?

Home Assistant servers (Raspberry Pi, mini PC, NAS)
Zigbee2MQTT systems
openHAB, ioBroker, Domoticz projects
Integrator test benches
Homes with Zigbee devices from various brands
Small offices with a local server

Use by need

For Home Assistant users.
The simplest way to add Zigbee to your server without a separate hub.

For smart home integrators.
One coordinator for devices of different brands and local control without the cloud.

For electricians.
ZBMINI, TRVZB and SNZB devices for customers with Home Assistant work via one stick.

Practical use

If Home Assistant runs on a Raspberry Pi and you want to connect 30 Zigbee sensors and relays, plug ZBDongle-E in via a USB extension cable, select it as the coordinator in the ZHA integration and pair the devices directly in the Home Assistant interface.

Pros

EFR32MG21 chip, +20 dBm transmitter
External SMA antenna
Aluminium housing
Compatible with ZHA, Zigbee2MQTT and others
Router mode available

Cons / limitations

Requires a computer or server with control software
No own app – controlled via Home Assistant etc.
Windows and macOS require a driver
Setup requires basic IT knowledge

Safety and installation notes

Connect via a USB extension cable, away from USB 3.0 ports and SSD interference
Do not keep it inside a metal cabinet or distribution board
Use one Zigbee coordinator per system
Back up the Zigbee network before firmware updates
Do not use in damp locations

Suitable when you need:

to add Zigbee to Home Assistant or another local system
to control Zigbee devices from various brands without the cloud
to build a large local Zigbee network

Check before use:

whether your system supports an EFR32 (EmberZNet) coordinator
whether a free USB port and extension cable are available
whether the devices are Zigbee 3.0 compatible
whether a driver is needed for your operating system

Important reminder: ZBDongle-E does not work on its own – it needs a computer or server with Home Assistant, Zigbee2MQTT or other control software.

FAQ

Does the stick work without a computer?
No, it needs a computer or server with control software.

Is it suitable for Home Assistant?
Yes, via the ZHA integration or Zigbee2MQTT.

Can it be used with eWeLink?
The stick is intended for local systems; for eWeLink users the ZBBridge-P hub is more suitable.

Why is a USB extension cable recommended?
It reduces radio interference from USB 3.0 and other devices.

Can the Zigbee network be extended?
Yes, by reflashing the stick to router mode or by using mains-powered Zigbee devices.

What antenna does it have?
An external antenna with an SMA connector.
