Data from the official Sonoff site.
2026 verdict
As a Zigbee coordinator you can put anywhere in the house, the Sonoff Dongle Max beats the Sonoff ZBDongle-E.
It connects over USB, Ethernet or Wi-Fi, takes power over PoE, runs a newer EFR32MG24 radio that can also act as a Thread border router, carries two external antennas at +5dBi and offers an experimental dual-network mode. The Sonoff ZBDongle-E answers with a two-year warranty against one year, a compact USB stick that is the more affordable of the two, and the same Zigbee 3.0, Home Assistant and Zigbee2MQTT support. Pick the Sonoff Dongle Max when the server sits in a corner and the mesh needs a central radio, and the Sonoff ZBDongle-E when a USB port near the middle of the home is enough.

What the differences mean
How it connects to the server
The Sonoff Dongle Max reaches Home Assistant over USB, Ethernet or Wi-Fi, so the radio can sit in the middle of the house on a network cable. The Sonoff ZBDongle-E is USB only, so it lives next to the machine running your smart home software, wherever that is.
Power over Ethernet
With PoE, the Sonoff Dongle Max needs a single cable for data and power, which makes a ceiling or hallway placement practical. The Sonoff ZBDongle-E draws its power from the USB port it is plugged into.
Thread
The EFR32MG24 in the Sonoff Dongle Max can act as a Thread border router for Matter devices, and it offers Zigbee and Thread at once as an experimental mode. The Sonoff ZBDongle-E is Zigbee only, so Thread would need a second radio.
Antennas
Both have +20 dBm of transmit power. The Sonoff Dongle Max adds two external antennas at +5dBi against a single 2 dBi antenna on the Sonoff ZBDongle-E, which matters most in a large or multi-floor home.
Warranty
Sonoff covers the Sonoff ZBDongle-E for two years and the Sonoff Dongle Max for one.
Which one to buy if
- your server sits in a basement or a far corner of the house
The Sonoff Dongle Max can move to the centre of the home on an Ethernet cable, with PoE carrying its power too.
- you want Zigbee and Thread from one device
Its EFR32MG24 radio is a Thread border router and offers an experimental dual-network mode; the Sonoff ZBDongle-E has no Thread.
- you just need a first Zigbee coordinator for a Home Assistant box
The Sonoff ZBDongle-E is the more affordable plug-in stick, with the same Zigbee 3.0 support and a two-year warranty.
- you would rather not deal with firmware and network settings
Owners describe the Sonoff ZBDongle-E as ready to use out of the box, while Sonoff Dongle Max owners mention thin documentation.

What owners say
Owners of both Sonoff coordinators say the same thing about the software side: Home Assistant, ZHA and Zigbee2MQTT pick them up quickly and Zigbee devices pair without fuss. Where they part is placement. Sonoff Dongle Max owners single out running it over Ethernet or PoE to reach dead zones, one covering a detached garage, and complain about thin documentation, a firmware update that needs a physical power cycle and a web portal that keeps asking for a login. Sonoff ZBDongle-E owners talk about value and about running dozens of mixed-brand devices on a stick that ships ready to use, and their standing advice is a USB 2.0 extension cable to keep it away from USB 3.0 interference, with a few reporting trouble pairing some Aqara sensors.
Frequently Asked Questions
Which is better overall: Sonoff Dongle Max or Sonoff ZBDongle-E?
The Sonoff Dongle Max. It adds Ethernet, PoE and Wi-Fi to USB, a Thread-capable EFR32MG24 radio and two +5dBi antennas. The Sonoff ZBDongle-E is still the simpler, more affordable USB coordinator with a longer two-year warranty.
What is the biggest difference between the Sonoff Dongle Max and the Sonoff ZBDongle-E?
Where the radio can live. The Sonoff Dongle Max is a network coordinator that can sit anywhere an Ethernet cable reaches, powered by PoE, while the Sonoff ZBDongle-E is a USB stick tied to the host machine.
Does the Sonoff Dongle Max or the Sonoff ZBDongle-E support Thread and Matter?
The Sonoff Dongle Max can act as a Thread border router for Matter-over-Thread devices. The Sonoff ZBDongle-E is Zigbee 3.0 only. Neither is a Matter bridge.
Do both work with Home Assistant and Zigbee2MQTT?
Yes. The Sonoff Dongle Max and the Sonoff ZBDongle-E both work as Zigbee 3.0 coordinators with Home Assistant (ZHA) and Zigbee2MQTT, and both can also run as Zigbee routers.
Who should buy the Sonoff Dongle Max?
Home Assistant users whose server is badly placed for Zigbee coverage, who have a PoE switch or want Thread on the same hardware, and who are comfortable with firmware updates.
Who should buy the Sonoff ZBDongle-E?
Anyone starting a Zigbee network on a Home Assistant host in a central spot, who wants a proven, affordable USB stick with a two-year warranty and no Thread needs.
