Aqara Hub M3 vs Meross Smart Wi-Fi Hub MSH450

The Aqara Hub M3 is the stronger hub overall, winning on connectivity, protocols and integrations with Zigbee, Thread, Matter, Bluetooth, IR, dual-band Wi-Fi and PoE. The Meross Smart Wi-Fi Hub MSH450 is the more affordable and better-rated option, but it is a Matter-only bridge for Meross devices.

Protocol breadth. The Aqara Hub M3 is a true multi-protocol hub with Zigbee, Thread, Matter, Bluetooth and IR, while the Meross Smart Wi-Fi Hub MSH450 has only Matter bridging and connects Meross's own Wi-Fi devices. The M3 also adds Home Assistant support that the MSH450 lacks.

Both do. The Meross Smart Wi-Fi Hub MSH450 has a louder 110dB siren, useful for pushing an alert through closed doors, while the Aqara Hub M3 includes a 95dB speaker for chimes and alarms. If a loud dedicated siren is the priority, the MSH450 edges it here.

Buy the Aqara Hub M3 if you want a flagship multi-protocol hub with Zigbee, Thread, Matter, Bluetooth and IR, PoE power, a 95dB speaker and support for up to 127 devices, bridging an Aqara home into HomeKit, Google, Alexa, SmartThings and Home Assistant.

Choose the Meross Smart Wi-Fi Hub MSH450 if you already use Meross water valves, leak and smoke sensors and want an affordable, well-rated hub that bridges them via Matter to HomeKit, Alexa, Google and SmartThings, with a loud 110dB siren and a stable Ethernet port. Wire it over Ethernet for reliability.
