Smlight SLZB-MRW10 vs Sonoff ZBDongle-P

Full Smart Dongles comparison in 2026

Updated August 2026
Data from Amazon and official Smlight and Sonoff sites.
2026 verdict
As an all-in-one smart home dongle, the Smlight SLZB-MRW10 outclasses the Sonoff ZBDongle-P: it brings a Z-Wave 800 controller, Thread border router support, network-connected placement (USB, Ethernet, Wi-Fi and PoE), stronger twin +5dBi antennas, simultaneous dual-network operation and a Bluetooth proxy, while the ZBDongle-P is a USB-only Zigbee-only coordinator. The MRW10 consolidates three protocols into one device for a cloud-free Home Assistant. The Sonoff ZBDongle-P remains a genuinely good buy where its strengths lie: it is the community's well-supported reference Zigbee stick on the proven Texas Instruments CC2652P, usually plug-and-play, more affordable, and backed by a longer 2-year warranty against the MRW10's single year. Choose the Smlight SLZB-MRW10 for full protocol coverage in one flexible coordinator; choose the Sonoff ZBDongle-P for a proven, cheaper Zigbee stick with the longer warranty.
