2026 verdict
One is a USB stick and the other a network gateway, and the Smlight SLZB-MRW10 wins this matchup over the Sonoff Dongle Plus MG24 on the radios it carries.
It adds a Z-Wave Series 800 controller on top of Zigbee and Thread, brings a Bluetooth proxy and a fully supported dual-network mode, and connects over Ethernet with PoE, USB or Wi-Fi, where the Sonoff Dongle Plus MG24 is a USB-only Zigbee and Thread stick. Both put +20 dBm of transmit power behind the Zigbee radio and both work with Home Assistant and Zigbee2MQTT or ZHA. The Sonoff Dongle Plus MG24 is far cheaper, genuinely plug-and-play and the easier recommendation for a Zigbee and Thread network on a budget. Choose the Smlight SLZB-MRW10 for a mixed Zigbee, Z-Wave and Thread home in one network-placed box, and the Sonoff Dongle Plus MG24 for a straightforward USB coordinator.

What the differences mean
Radios
The Smlight SLZB-MRW10 carries Zigbee, Thread and a Z-Wave Series 800 controller plus a Bluetooth proxy. The Sonoff Dongle Plus MG24 has a single Zigbee and Thread radio, so Z-Wave or Bluetooth sensors need another device.
Placement
The Smlight SLZB-MRW10 connects over Ethernet with PoE, USB or Wi-Fi, so it can be mounted centrally. The Sonoff Dongle Plus MG24 is a USB stick that stays with the host, though its long body and bundled extension help with interference.
Z-Wave
Only the Smlight SLZB-MRW10 includes a Z-Wave Series 800 controller. The Sonoff Dongle Plus MG24 has no Z-Wave, so a home with Z-Wave locks or sensors must run a second dongle beside it.
Dual network
The Smlight SLZB-MRW10 runs Zigbee and Thread at the same time with a dedicated radio for each. The Sonoff Dongle Plus MG24 is flashed for one or the other, so it cannot serve both protocols simultaneously.
Price and setup
The Sonoff Dongle Plus MG24 costs far less and is the more plug-and-play of the two, with a fixed antenna and one radio. The Smlight SLZB-MRW10 costs more and asks you to plan its network placement, which pays off only if you use the extra radios.
Which one to buy if
- your home mixes Zigbee, Thread and Z-Wave
The Smlight SLZB-MRW10 covers all three plus Bluetooth in one network-placed gateway, where the Sonoff needs partners for Z-Wave and Bluetooth.
- you run Zigbee and Thread on a budget
The Sonoff Dongle Plus MG24 does both protocols for far less, with strong range and genuine plug-and-play setup.
- the coordinator needs to sit away from the server
Ethernet with PoE gives the Smlight SLZB-MRW10 a central position the USB-only Sonoff cannot match.
- you want to unbox and pair devices in minutes
The Sonoff Dongle Plus MG24 is recognized instantly with no flashing, which is the simpler first install of the two.

What owners say
Sonoff Dongle Plus MG24 owners lead with how little setup it needs: it is recognized the moment it is plugged into a Home Assistant server, with no flashing, and pairs devices within minutes through ZHA or Zigbee2MQTT. They like the compact, cool-running design as an upgrade over the older ZBDongle-P, the bundled USB extension cable for moving the antenna away from interference, and the fact that it can be flashed to serve as a Thread border router. Range and stability hold up with dozens of devices through thick walls. Their gripes are small: the external antenna is fixed and cannot be swapped, there is no mounting point, and virtual machine passthrough, especially on Hyper-V, needs a workaround.
Price history compared

Frequently Asked Questions
Which is better overall: Smlight SLZB-MRW10 or Sonoff Dongle Plus MG24?
The Smlight SLZB-MRW10 is the more complete device, covering Zigbee, Thread and Z-Wave with a Bluetooth proxy and Ethernet placement. The Sonoff Dongle Plus MG24 is the better value for Zigbee and Thread alone, far cheaper, plug-and-play and equally strong on range.
What is the biggest difference between the Smlight SLZB-MRW10 and the Sonoff Dongle Plus MG24?
The radio set and the connection. The Smlight SLZB-MRW10 adds a Z-Wave Series 800 controller and a Bluetooth proxy and connects over Ethernet with PoE, while the Sonoff Dongle Plus MG24 is a USB-only Zigbee and Thread stick. That is the whole decision between them.
Does the Smlight SLZB-MRW10 or the Sonoff Dongle Plus MG24 support Z-Wave?
Only the Smlight SLZB-MRW10. It carries a Z-Wave Series 800 controller alongside Zigbee and Thread. The Sonoff Dongle Plus MG24 has no Z-Wave, so it is Zigbee and Thread only.
Can these run Zigbee and Thread at once?
The Smlight SLZB-MRW10 can, using a dedicated radio for each protocol. The Sonoff Dongle Plus MG24 can be flashed to run as a Thread border router, but it works as one or the other rather than both at the same time.
Who should buy the Smlight SLZB-MRW10?
A home that runs or plans to run Zigbee, Z-Wave and Thread together and wants one network-connected coordinator instead of a USB stick per protocol.
Who should buy the Sonoff Dongle Plus MG24?
Anyone running Zigbee and Thread who wants a cheap, modern, genuinely plug-and-play USB coordinator with strong range, and who does not need Z-Wave or Ethernet placement.
