Arlo Pro SmartHub vs Meross Smart Wi-Fi Hub MSH450

The Meross Smart Wi-Fi Hub MSH450 wins overall. It costs less, is better rated, bridges devices into HomeKit, Alexa, Google Home and SmartThings over Matter, and adds a 110dB siren. The Arlo Pro SmartHub has no smart home protocols and serves only Arlo cameras.

Matter. The Meross Smart Wi-Fi Hub MSH450 is a Matter bridge that exposes Meross sensors, valves and detectors to Apple Home, Alexa, Google Home and SmartThings. The Arlo Pro SmartHub supports no Matter, Zigbee, Z-Wave or Thread at all, and exists purely to connect and record Arlo cameras.

Yes, and on both it is the better way to connect. The Meross Smart Wi-Fi Hub MSH450 is known for flaky Wi-Fi behavior on some networks, so owners recommend wiring it. The Arlo Pro SmartHub also supports Ethernet alongside 2.4GHz Wi-Fi, and a wired connection helps keep camera streams stable.

No. The Meross Smart Wi-Fi Hub MSH450 pairs Meross accessories only, so it is a gateway for that ecosystem rather than a universal Zigbee or Z-Wave hub. What it does add is Matter bridging outward, so those Meross devices appear in whichever platform you already use.

Buy the Meross Smart Wi-Fi Hub MSH450 if you run Meross sensors, water valves, leak or smoke detectors and want them visible in Apple Home, Alexa, Google Home or SmartThings. The built-in 110dB siren is a genuine safety upgrade, and wiring it over Ethernet avoids the Wi-Fi complaints.

Buy the Arlo Pro SmartHub only if you own Arlo cameras and want faster response, longer range, 2K live streaming on Essential and Ultra models and local USB storage. It will not pair any sensor, light or lock, and Arlo's event detection and recording still require a subscription.
