Smlight SLZB-07 MG24 vs Sonoff Dongle-PZG23

The SLZB-07 MG24 comes out ahead in this matchup thanks to its Zigbee router support, Thread border router capability and stronger antenna gain, but the Dongle-PZG23 is cheaper, better rated, and the only one of the two with a Z-Wave controller.

Wireless protocol. The SLZB-07 MG24 is a Zigbee 3.0 coordinator and router with Thread border router support, while the Dongle-PZG23 is a dedicated Z-Wave 800 controller with no Zigbee or Thread capability whatsoever.

Yes, the Dongle-PZG23 costs less and also carries a higher owner rating, making it the more attractive option for buyers whose devices run on Z-Wave rather than Zigbee.

No. The SLZB-07 MG24 handles Zigbee and Thread only, and the Dongle-PZG23 handles Z-Wave only. Buyers who need both protocols would have to run one of each rather than relying on a single stick.

Home Assistant users running Zigbee devices, especially those who also want a Thread border router for Matter devices, should choose the SLZB-07 MG24 over the Z-Wave-only Dongle-PZG23.

Buyers with a Z-Wave-based smart home who want a cheaper, higher-rated controller with S2 security should choose the Dongle-PZG23, since the SLZB-07 MG24 cannot handle Z-Wave devices at all.
