Meross Smart Wi-Fi Hub MSH400HK Review: A Cheap HomeKit Hub With a Built-In 110 dB Siren
Connects up to 24 Meross sub-devices over Wi-Fi or Ethernet and works with Alexa, Google Home and Apple HomeKit, but speaks no Zigbee, Z-Wave, Thread or Matter.
The Meross MSH400HK is an inexpensive hub for people already buying Meross sensors and accessories. It handles up to 24 sub-devices, connects to your network over 2.4 GHz Wi-Fi or Ethernet, and carries a 110 dB speaker that doubles as an alarm or chime. Its best trick at this price is platform support: Alexa, Google Home and Apple HomeKit are all covered. What it is not is a universal hub. There is no Zigbee, no Z-Wave, no Thread border router, no Matter bridge and no Home Assistant support, so it only extends the Meross ecosystem.

Who is the Meross MSH400HK for?
It is the companion piece for a Meross setup: buy it because you want the brand's sensors and accessories to reach your phone and your voice assistant, not because you want a hub that unifies devices from different manufacturers. Support for Alexa, Google Home and Apple HomeKit means the sub-devices it manages show up in whichever of those apps you already use, and HomeKit support in particular is rare at this price. Capacity is 24 sub-devices, which is enough for a normal house of contact sensors, buttons and similar accessories.
What stands out
Two things. First, the network options: alongside 2.4 GHz Wi-Fi it has an Ethernet port, and a wired connection is more stable and lower latency than Wi-Fi for a device that everything else in the system depends on. Second, the built-in 110 dB speaker, which turns the hub itself into an alarm or a doorbell chime, so a sensor trigger can make a noise loud enough to hear across the house without buying a separate siren. It is small enough to sit on a shelf or behind furniture near the router.
What to know before you buy
The protocol list is empty in every direction that matters for mixed-brand smart homes: no Zigbee coordinator, no Z-Wave, no Bluetooth, no Thread border router, no Matter bridge and no infrared. That means it will not adopt third-party sensors, and it will not expose anything to a Matter controller. Home Assistant is not supported, and neither is Samsung SmartThings, so the automation options are limited to the three big voice platforms plus the Meross app. It has no built-in temperature, humidity, light or motion sensing of its own, no microphone, no microSD slot and no PoE, and none of the integrator features (ONVIF, RTSP, Node-RED, Tailscale) are available. It also runs on 2.4 GHz Wi-Fi only if you do not use the Ethernet port.
Is the Meross MSH400HK worth it?
At its price it is close to an accessory rather than an investment, and judged that way it does well: Ethernet, a loud built-in siren and HomeKit support are all above what the category normally offers this cheaply. The decision is really about lock-in. If your accessories are Meross, it is an easy yes. If you were hoping for one hub to run Zigbee sensors, Z-Wave locks and Matter devices together, this is not that product, and no firmware update will make it one.
Frequently asked questions
Does the Meross MSH400HK work with Apple HomeKit?
Yes. Apple HomeKit, Alexa and Google Home are all supported. Home Assistant and Samsung SmartThings are not.
Can it connect Zigbee or Z-Wave devices?
No. It has no Zigbee, Z-Wave, Bluetooth, Thread or Matter bridge capability, so it only works with Meross sub-devices.
How many devices can it handle?
Up to 24 sub-devices.
Can it be wired to the router?
Yes. It has an Ethernet port as well as 2.4 GHz Wi-Fi, and the wired connection is the more stable option for a hub.
What is the built-in speaker for?
It is a 110 dB speaker, loud enough to act as an alarm siren or a doorbell chime when one of your sub-devices triggers.
