Aqara Hub M3 vs Sonoff Zigbee Bridge Ultra

The Sonoff Zigbee Bridge Ultra wins overall on price, owner rating and its 2-year warranty, and it supports up to 256 devices. The Aqara Hub M3 is broader in protocols, adding Thread, Bluetooth, IR and dual-band Wi-Fi that the Sonoff does not have.

Protocol range and capacity. The Sonoff Zigbee Bridge Ultra is a Zigbee-plus-Matter hub with a large 256-device ceiling. The Aqara Hub M3 adds Thread, Bluetooth, IR and dual-band Wi-Fi with PoE but supports fewer devices at 127. Both are best with their own brand's Zigbee gear.

Both are limited. The Aqara Hub M3 only pairs Aqara devices over Zigbee, so others come in via Matter, while the Sonoff Zigbee Bridge Ultra works best with Sonoff gear and famously will not pair Philips Hue bulbs. For broad third-party Zigbee, neither is ideal, though both bridge over Matter.

Buy the Sonoff Zigbee Bridge Ultra if you want an affordable, stable Zigbee hub with Matter bridging, a 256-device ceiling, a built-in speaker and a 2-year warranty, especially for a Sonoff Zigbee setup. It works with HomeKit, Google, Alexa, SmartThings and Home Assistant over Wi-Fi or Ethernet.

Choose the Aqara Hub M3 if you want a multi-protocol hub with Zigbee, Thread, Matter, Bluetooth, IR, dual-band Wi-Fi and PoE, plus a 95dB speaker and up to 127 devices, bridging an Aqara home into HomeKit, Google, Alexa, SmartThings and Home Assistant.
