Sonoff Dongle Lite MG21 vs Zooz Z-Wave Long Range Stick

It depends on your devices, but the Sonoff Dongle Lite MG21 wins overall as the cheaper, more flexible stick that covers Zigbee and, once flashed, Thread. The Zooz Z-Wave Long Range Stick is the pick if you run Z-Wave, thanks to its Z-Wave 800 Long Range controller, higher rating and 5-year warranty.

Protocol. The Dongle Lite MG21 is a Zigbee coordinator that can flash into a Thread radio, while the Zooz is a dedicated Z-Wave 800 controller with Long Range and S2 security. They serve different device ecosystems, so what you already own decides the winner.

The Zooz Z-Wave Long Range Stick has a much longer 5-year warranty, versus 1 year on the Sonoff Dongle Lite MG21. Both are USB-only radios that plug into a host running Home Assistant.

Buy the Sonoff Dongle Lite MG21 if you want an affordable Zigbee coordinator or router for Home Assistant, with the option to flash it for Thread and Matter. It has no Z-Wave.

Buy the Zooz Z-Wave Long Range Stick if your smart home runs on Z-Wave and you want a plug-and-play Z-Wave 800 Long Range controller with S2 security, a high owner rating and a 5-year warranty. It does no Zigbee or Thread and is indoor-only.
