Meross Matter Hub Pro MSH450P and Sensor Kits Pre-Order

Meross is bridging a new sensor family into Matter through a hub—not by making each sensor a native Matter endpoint. On September 23, 2026, HomeKit News reported that pre-orders are open for the MSH450P Matter Smart Hub Pro and four kits covering temperature/humidity, doors, water leaks, and programmable controls. Meross expects orders to begin shipping on September 28.

Hub first, sensors second

The battery sensors talk to the hub over Bluetooth Low Energy. The hub then provides Matter connectivity for Apple Home, Google Home, Alexa, and Home Assistant. HomeKit News flags that BLE-to-hub design as a likely turn-off for some Apple Home users who want Thread or native Matter sensors. The MSH450P joins Ethernet or 2.4GHz Wi-Fi and supports up to 32 Meross devices. It keeps a 433MHz radio for compatible older Meross accessories; owners of the previous MSH450 can migrate with one tap, Meross says. The hub can announce events aloud (door open, leak) with customizable messages and multiple languages; local alarms on hub and sensors are said to keep working if the network drops.

• MS120H: temp/humidity, 1.9-inch display, up to 100dB alarm, dew point / absolute humidity / VPD; ~3-year battery claim
• MS220H: open/closed plus vibration, left-open alerts, buzzer, doorway light, doorbell mode, automation button; ~3-year battery
• MS420H: leak / rain / drip / freeze / water level, 1.5 m probe, up to 100dB; ~4-year battery
• MS700H: programmable button, three switchable screens, up to nine custom controls, env readings; ~2.5-year battery

All four are IP66 with a stated −20°C to 60°C range. HomeKit News stresses that vibration alerts, doorbell mode, combined leak conditions, and the MS700H’s nine controls may not all appear in Apple Home through Matter—feature exposure is unproven until units ship.

US store prices (pre-sale)

Meross listed the hub at a pre-sale US$26.99. MS120H, MS220H, and MS420H are US$22.99 alone or US$43.99 in a hub starter kit; MS700H is US$28.99 or US$42.99 with the hub. All four sensors require the MSH450P.

Why BLE-to-Matter matters for buyers

HomeKit News frames the MSH450P as a Matter-over-bridge design: sensors stay on Meross’s BLE (and legacy 433 MHz) radios while the hub speaks Matter upstream. That architecture can be fine for mixed Google/Alexa/Home Assistant homes, but Apple Home users who expected Thread sensors joining the fabric directly may find feature gaps—especially vibration alerts, doorbell mode, combined leak conditions, and the MS700H’s nine custom controls, which Meross describes in marketing without proving Matter cluster exposure. Until units ship around September 28, treat advanced automation lists as vendor intent. Starter-kit pricing (sensor + hub around the mid-$40s USD for several SKUs) is cheaper than buying a hub and three sensors à la carte, but every sensor still requires the MSH450P—there is no standalone Matter path in this launch wave.

FAQ

Are the sensors native Matter devices? No—they are BLE accessories that the hub exposes over Matter.

When do pre-orders ship? Meross expects shipping to start September 28, per HomeKit News.
