Smlight SLZB-07 MG24 vs Sonoff ZBDongle-P

The Sonoff ZBDongle-P is the better value, with a lower price, longer warranty and higher owner rating. The SLZB-07 MG24 is the better pick if you specifically want Thread border router support and stronger antenna gain, which the ZBDongle-P does not offer.

Thread support again separates them: the SLZB-07 MG24 doubles as a Thread border router for Matter devices, while the ZBDongle-P is a Zigbee-only coordinator, though it costs less and carries a longer warranty.

The Sonoff ZBDongle-P has a longer warranty than the Smlight SLZB-07 MG24, which along with its lower price and stronger owner rating makes it the safer bet for buyers who only need Zigbee.

Yes, it is widely used for exactly that in Home Assistant setups via ZHA or Zigbee2MQTT. That use case does not depend on Thread support, so the ZBDongle-P's lack of it is not a drawback for buyers focused purely on Zigbee devices.

Home Assistant users who want the well-established, affordable, long-warrantied Zigbee coordinator and do not need Thread should choose the ZBDongle-P.

Buyers who want Thread border router capability for Matter devices, along with stronger antenna gain, should pick the SLZB-07 MG24 over the Zigbee-only ZBDongle-P.
