Smlight SLZB-07P10 vs Sonoff Dongle Plus MG24

The Sonoff Dongle Plus MG24 is the easier and cheaper choice for most people: it is plug-and-play with Home Assistant and better reviewed. Pick the Smlight SLZB-07P10 only if you want its high-power Texas Instruments CC2652P10 radio and are willing to flash firmware.

Setup and the radio chip. The Sonoff Dongle Plus MG24 (Silicon Labs EFR32MG24) runs out of the box with no flashing, while the Smlight SLZB-07P10 uses the Texas Instruments CC2652P10 but ships with outdated firmware that must be flashed before it works.

Yes. Both the Smlight SLZB-07P10 and the Sonoff Dongle Plus MG24 are Zigbee 3.0 coordinators that can be flashed to act as a Thread border router for Matter. Neither includes Z-Wave, and both are USB-only rather than network-connected.

The Smlight SLZB-07P10 uses a single external antenna rated +3dB, and the Sonoff Dongle Plus MG24 has a permanently fixed antenna rated +4.5dBi that you cannot swap, though it ships with a USB extension cable to move the whole stick away from interference.

Buy the Sonoff Dongle Plus MG24 if you want a modern, truly plug-and-play Zigbee coordinator (with optional Thread) for Home Assistant at a lower price, and you are happy with a fixed antenna and a USB stick rather than a network radio.

Buy the Smlight SLZB-07P10 if you prefer the high-power Texas Instruments CC2652P10 chip in a very compact USB coordinator and are comfortable flashing the current firmware before adding devices. It is Zigbee and Thread only, with no Z-Wave.
