2026 verdict
For a coordinator that has to sit away from the server, the Sonoff Dongle Max is the stronger of Sonoff's two EFR32MG24 radios, since it runs over Ethernet, PoE, Wi-Fi or USB.
It also carries two +5 dBi external antennas and an experimental mode for running Zigbee and Thread at the same time. The Sonoff Dongle Plus MG24 is the simpler USB stick, compact and plug-and-play in Home Assistant, with a USB extension cable in the box and the same chip, the same +20 dBm transmit power and the same Thread border router role, and it is the better reviewed of the pair. Neither does Z-Wave or Matter bridging. Pick the Sonoff Dongle Max if the Zigbee network needs central placement on a network cable, and the Sonoff Dongle Plus MG24 if the Home Assistant host is already well placed.

What the differences mean
Network connection
The Sonoff Dongle Max joins the network over Ethernet, PoE or Wi-Fi, so it can live in the middle of the home on one cable. The Sonoff Dongle Plus MG24 is a USB stick that stays next to the Home Assistant host, moved a little with its extension cable.
Zigbee and Thread together
The Sonoff Dongle Max lists dual-network operation as experimental. The Sonoff Dongle Plus MG24 runs Zigbee or Thread, one at a time, which is why some owners pair it with a second stick.
Antennas
The Sonoff Dongle Max has two external +5 dBi antennas; the Sonoff Dongle Plus MG24 has one fixed +4.5 dBi antenna that cannot be replaced. Both have the same +20 dBm transmit power.
Setup effort
The Sonoff Dongle Plus MG24 is plug-and-play over USB. The Sonoff Dongle Max adds a web portal and network setup, and its owners say firmware updates are thinly documented.
Which one to buy if
- your server sits far from the Zigbee devices
The Sonoff Dongle Max can be placed anywhere an Ethernet or PoE cable reaches.
- you want a stick you plug in and forget
Owners describe the Sonoff Dongle Plus MG24 as recognised instantly by Home Assistant with no configuration.
- you want to experiment with Zigbee and Thread on one radio
Only the Sonoff Dongle Max offers a dual-network mode, still marked experimental.
- you want the Thread radio next to a separate Zigbee stick
Sonoff Dongle Plus MG24 owners often dedicate one to Thread, flashed easily through Sonoff's web tool.

What owners say
Owners of both Sonoff coordinators describe smooth integration with Home Assistant, ZHA and Zigbee2MQTT, and range they are happy with. Sonoff Dongle Max owners single out the freedom of USB, Ethernet or PoE placement, one covering a detached garage about 30 meters away, while they complain about a firmware update that needs a physical power cycle nobody documents, a web portal that keeps asking to log in and a few devices dropping off. Sonoff Dongle Plus MG24 owners describe a stick that is recognised instantly with no flashing, a compact, cool-running body and an easy web flasher for Thread; their gripes are an antenna fixed to the body, no mounting point and a workaround under Hyper-V.
Price history compared

Yes. Both the Sonoff Dongle Max and the Sonoff Dongle Plus MG24 are built on the Silicon Labs EFR32MG24 with +20 dBm of transmit power, and both can act as a Thread border router. The difference is how they connect and their antennas.
