Smlight SLZB-06p7U vs Sonoff Dongle Max

The Smlight SLZB-06p7U, with a stronger owner rating and a Bluetooth proxy that the Sonoff Dongle Max lacks. The Sonoff Dongle Max counters with an experimental dual-network mode.

It relays nearby Bluetooth devices, such as temperature sensors or trackers, into your smart-home system over the network. The Smlight SLZB-06p7U includes one, so it can cover Bluetooth in that part of the house without an extra device.

Yes. Both run over USB, Ethernet or PoE, so either can be placed centrally, away from USB 3 ports and metal cases that cause Zigbee interference. That flexibility is a key reason to pick a network coordinator over a plain USB stick.

Yes, both the Smlight SLZB-06p7U and the Sonoff Dongle Max act as a Thread border router as well as a Zigbee coordinator, so they can carry Matter over Thread devices too.

It allows two networks to run from the same stick, which helps when migrating from an old coordinator or keeping a test network apart. It is labelled experimental, so treat it accordingly on a network you rely on.

Users who specifically want to run two networks from one coordinator and are comfortable with an experimental feature on core smart-home infrastructure.

Most users: it is the better rated of the two, supports USB, Ethernet and PoE placement, acts as a Thread border router, and adds Bluetooth proxying so one device covers more of the house.
