Aeotec Z-Stick 7 vs Sonoff Dongle Max

The Sonoff Dongle Max is the stronger overall coordinator thanks to USB, Ethernet and PoE placement, a Thread border router and dual-network support. The Aeotec Z-Stick 7 is the better pick only if you need Z-Wave specifically, or want the cheaper, higher-rated stick, since the Dongle Max has no Z-Wave.

How they connect and which radios they carry. The Sonoff Dongle Max runs over USB, Ethernet or PoE and does Zigbee plus Thread, while the Aeotec Z-Stick 7 is USB-only and Z-Wave 700 only. That makes them complementary rather than direct rivals.

Only the Sonoff Dongle Max, which supports USB, Ethernet and Power over Ethernet, so owners mount it far from the server to reach dead zones on one cable. The Aeotec Z-Stick 7 must plug directly into a USB port on the host machine.

Only the Aeotec Z-Stick 7, a dedicated Z-Wave 700 controller. The Sonoff Dongle Max is a Zigbee 3.0 coordinator and Thread border router with no Z-Wave, so a Z-Wave network would need a separate controller.

Buy the Sonoff Dongle Max if you want a flexible Zigbee (and Thread) coordinator you can power over USB, Ethernet or PoE and place anywhere for range, and you are comfortable with occasional DIY troubleshooting. Note its dual-network mode is still experimental.

Buy the Aeotec Z-Stick 7 if you need an affordable, dependable Z-Wave 700 controller for Home Assistant, openHAB or ioBroker and value long-term stability. Plan to update its shipping firmware first, and know it does no Zigbee or Thread.
