2026 verdict
The Sonoff Dongle Plus MG24 takes this one on Thread, since Sonoff's newer USB coordinator can double as a Thread border router while the Sonoff ZBDongle-P stays Zigbee only.
It moves from the Texas Instruments CC2652P to a Silicon Labs EFR32MG24, raises antenna gain from 2 to +4.5 dBi, drops the bulky aluminium case for a compact, cooler-running body and adds a USB extension cable in the box. The Sonoff ZBDongle-P keeps two advantages: it is the lower priced of the two and it carries a two-year warranty against one, on a chip that owners describe as the community reference. Both keep the +20 dBm transmit power, router mode and ZHA and Zigbee2MQTT support. Pick the Sonoff Dongle Plus MG24 for a new install, and the Sonoff ZBDongle-P if your network already runs on Texas Instruments hardware.

What the differences mean
Thread support
The Sonoff Dongle Plus MG24 can be flashed as a Thread border router for Matter devices. The Sonoff ZBDongle-P cannot, so a Thread network would need a second radio.
Chip family
The Sonoff ZBDongle-P runs a Texas Instruments CC2652P and the Sonoff Dongle Plus MG24 a Silicon Labs EFR32MG24. For a brand new network it does not matter, but moving an existing Texas Instruments network to a Silicon Labs coordinator is a bigger step than moving between two sticks of the same family.
Case and antenna
The Sonoff ZBDongle-P comes in a bulky aluminium case with a 2 dBi antenna. The Sonoff Dongle Plus MG24 is smaller, runs cooler and has a +4.5 dBi antenna, though that antenna is fixed to the body.
Warranty
The Sonoff ZBDongle-P is covered for two years, the Sonoff Dongle Plus MG24 for one.
Which one to buy if
- you are starting a new Zigbee network and may add Thread later
The Sonoff Dongle Plus MG24 covers both roles, one at a time, from a single stick.
- your current network runs on a Texas Instruments coordinator
The Sonoff ZBDongle-P keeps the same CC2652P chip family, and owners report migrations in about ten minutes.
- the stick plugs into a crowded USB area
The Sonoff Dongle Plus MG24 is compact and ships with an extension cable, while the ZBDongle-P case is bulky.
- a longer warranty matters to you
The Sonoff ZBDongle-P carries two years of warranty against one on the Sonoff Dongle Plus MG24.

What owners say
Owners of both sticks describe a coordinator Home Assistant picks up at once and a Zigbee network that stays stable with dozens of devices. Sonoff ZBDongle-P owners single out responsiveness they find smoother than a ConBee II, quick migration that keeps IEEE addresses and a premium feel, while complaining that the case is bulky enough to need an extension, that VM passthrough can take troubleshooting and that the flashing instructions are rough. Sonoff Dongle Plus MG24 owners praise a smaller, cooler design without the big heatsink and an easy web flasher for Thread, and their complaints are an antenna that cannot be replaced, no mounting point and a COM-port workaround under Hyper-V.
Upgrading from the Sonoff ZBDongle-P?
Moving from the Sonoff ZBDongle-P to the Sonoff Dongle Plus MG24 buys Thread border router support, a higher gain antenna and a smaller, cooler body. Zigbee itself does not get better in a way owners report: both are Zigbee 3.0 coordinators with the same transmit power. Since the chip family changes from Texas Instruments to Silicon Labs, a working network is not a quick swap. If your Sonoff ZBDongle-P runs your Zigbee devices well and you have no Thread plans, keep it.
Price history compared
Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.

Frequently Asked Questions
Which is better overall: Sonoff Dongle Plus MG24 or Sonoff ZBDongle-P?
The Sonoff Dongle Plus MG24 for a new setup, because it adds Thread border router support, a +4.5 dBi antenna and a compact design. The Sonoff ZBDongle-P is the lower priced, Zigbee-only stick with a two-year warranty and the Texas Instruments CC2652P chip.
Can the Sonoff Dongle Plus MG24 be a Thread border router?
Yes. After flashing the Thread firmware with Sonoff's web flasher, the Sonoff Dongle Plus MG24 runs as a Thread border router with the OpenThread Border Router in Home Assistant. The Sonoff ZBDongle-P has no Thread support.
Is the Sonoff Dongle Plus MG24 the successor to the Sonoff ZBDongle-P?
Yes, it is the newer Sonoff Zigbee USB coordinator. The Sonoff Dongle Plus MG24 moves to a Silicon Labs EFR32MG24 with Thread support, while the Sonoff ZBDongle-P uses a Texas Instruments CC2652P.
What is the biggest difference between the Sonoff Dongle Plus MG24 and the Sonoff ZBDongle-P?
The chip and what it enables: the Sonoff Dongle Plus MG24's EFR32MG24 can run Thread as well as Zigbee, while the Sonoff ZBDongle-P's CC2652P is used here as a Zigbee coordinator only.
Who should buy the Sonoff Dongle Plus MG24?
New Home Assistant users and anyone who wants a single compact stick that can serve Zigbee now and Thread for Matter devices later.
Who should buy the Sonoff ZBDongle-P?
Buyers who want a proven Zigbee-only coordinator at a lower price with a two-year warranty, or who are staying on the Texas Instruments chip family.
