Smlight SLZB-MRW10 vs Sonoff Dongle Plus MG24 comparison

Updated August 2026

Data from Amazon and official Smlight and Sonoff sites.

2026 verdict

The Smlight SLZB-MRW10 is the far more capable smart home dongle in this pairing, adding a Z-Wave 800 controller, network-connected placement (USB, Ethernet, Wi-Fi and PoE), stronger twin +5dBi antennas, simultaneous dual-network operation and a Bluetooth proxy over the USB-only Sonoff Dongle Plus MG24. That turns it into a one-box, three-protocol coordinator (Zigbee, Thread and Z-Wave) for a cloud-free Home Assistant, where the Dongle Plus MG24 covers only Zigbee and Thread. The Sonoff Dongle Plus MG24 remains a strong value pick: it is the more affordable, better-reviewed choice that is truly plug-and-play with ZHA or Zigbee2MQTT and ships with a USB extension cable, ideal when you only need a simple Zigbee coordinator. Go with the Smlight SLZB-MRW10 for full protocol coverage and flexible placement; go with the Sonoff Dongle Plus MG24 for a cheaper, no-fuss USB Zigbee stick.
