2026 verdict
As USB Zigbee coordinators go, the Sonoff ZBDongle-E is the better all-round buy than the Smlight SLZB-07P10, with a 2-year warranty, a lower price and a pre-flashed, plug-and-play start.
The Smlight SLZB-07P10 pulls ahead on hardware: a Texas Instruments CC2652P10 chip, a +3dB antenna and a Thread border router role that the Sonoff lacks. Both list +20dBm of amplifier gain, Zigbee 3.0 as coordinator and router, and Home Assistant and Zigbee2MQTT support over USB only. The catch with the Smlight SLZB-07P10 is that it ships with outdated firmware you flash yourself. Pick the Sonoff ZBDongle-E for a simple Zigbee network, and the Smlight SLZB-07P10 if you also want Thread for Matter devices.

What the differences mean
Thread border router
The Smlight SLZB-07P10 can act as a Thread border router for Matter devices. The Sonoff ZBDongle-E is Zigbee only, so it cannot serve Thread.
Setup and firmware
The Sonoff ZBDongle-E ships pre-flashed and Home Assistant recognizes it at once. The Smlight SLZB-07P10 arrives with old firmware that must be updated, a small job for a technical user and a stumbling block for a beginner.
Chip and antenna
The Smlight SLZB-07P10 uses the Texas Instruments CC2652P10 with a +3dB antenna, and the Sonoff ZBDongle-E the Silicon Labs EFR32MG21 with +2dBi. Both list +20dBm of amplifier gain, so real-world range should be close.
Warranty
The Sonoff ZBDongle-E is covered for 2 years and the Smlight SLZB-07P10 for one.
Which one to buy if
- you want a cheap, proven Zigbee coordinator with no flashing
The Sonoff ZBDongle-E ships pre-flashed, works with ZHA at once and has the longer warranty.
- you want Matter over Thread from the same USB stick
The Smlight SLZB-07P10 lists a Thread border router and the Sonoff ZBDongle-E does not.
- you prefer a Texas Instruments Zigbee chip
The Smlight SLZB-07P10 uses the CC2652P10, while the Sonoff ZBDongle-E uses a Silicon Labs chip.
- you want to replace a brand bridge such as a Hue Bridge
Sonoff ZBDongle-E owners describe that swap working with dozens of devices and no firmware step.

What owners say
Owners of the Sonoff ZBDongle-E describe a coordinator that is rock-solid the day it is plugged in: ZHA recognizes it with no flashing, networks of 40-plus mixed-brand devices run smoothly and many used it to retire a Philips Hue Bridge. They recommend a USB 2.0 extension cable and a few had trouble pairing some Aqara sensors. Smlight SLZB-07P10 owners like its size, the high-power chip and antenna for range and painless migration from an older stick with the Migrate Adapter tool, and it can double as a Thread radio. They also say it ships with outdated firmware, that flashing Thread firmware can fail, especially on Mac and Windows, and that documentation is scarce.
Price history compared
