Aqara Hub M3 vs Home Assistant Green

The Aqara Hub M3 wins overall, leading on price, connectivity and protocols with built-in Zigbee, Thread, Matter, Bluetooth, IR and dual-band Wi-Fi.

Radios out of the box. The Aqara Hub M3 has Zigbee, Thread and Matter built in, while the Home Assistant Green ships without on-board Zigbee, Thread or Bluetooth and requires the Connect ZBT-1 dongle. The Green is far more open across brands; the M3 is centered on the Aqara ecosystem.

The Home Assistant Green. It unifies devices across brands under local control and adds ONVIF, RTSP, Node-RED and Tailscale for power users. The Aqara Hub M3 only pairs Aqara devices over Zigbee, so third-party gear must come in over Matter, making it more of an Aqara-first hub.

Buy the Aqara Hub M3 if you want an affordable all-in-one hub with Zigbee, Thread, Matter, Bluetooth, IR, dual-band Wi-Fi and PoE, plus a 95dB speaker and support for up to 127 devices, bridging Aqara gear into HomeKit, Google, Alexa, SmartThings and Home Assistant.

Choose the Home Assistant Green if you want the easiest official on-ramp to Home Assistant, with fully local, private, multi-brand control and power-user features like ONVIF, RTSP, Node-RED and Tailscale.
