Meross MSH450P Matter Hub Pro Lands With Three New Sensors

Budget Matter just got another door in. On September 15, 2026, T3 reported Meross’s launch of the MSH450P Matter Smart Hub Pro alongside three new sensors covering climate, openings, and water leaks.

Hub hardware and price

The MSH450P is listed at £25.99 / $34.99 on Meross’s store. T3 highlights a multi-radio design—Wi-Fi, Ethernet, BLE, and 433MHz—with support for up to 32 connected devices, an IP65 rating, a CR123A battery, and an operating range of −20°C to 60°C. Meross pitches Bluetooth + Matter for more flexible setups and the ability to read device data from a phone without internet.

The three sensors

• MS120H (£38.99 / $51.99) — temperature & humidity at 0.1°C / 1% RH resolution (−20°C–60°C), usable for automations
• MS220H (£38.99 / $51.99) — door/window sensor that can drive security alerts and scenes via the hub
• MS420H (£19.99) — water-leak sensor with local audible/voice alerts even if your phone is elsewhere

What to clarify before buying

T3’s piece is strong on SKUs and street prices; it is lighter on Thread border-router behavior and which Matter ecosystems get full sensor traits. If you already live in Apple Home or Google Home, verify commissioning and which attributes cross the bridge before you standardize on Meross radios.

Why multi-radio still matters in 2026

Matter promised one language for smart homes; radios still decide who hears whom. Meross leaning on Wi-Fi, Ethernet, BLE, and legacy 433MHz is a pragmatic hedge for homes that already own older RF sensors while wanting a Matter front door. The IP65 + CR123A combo also hints at placements that are not always a dry closet shelf—garages, utility rooms, and exterior-adjacent installs where a mains-only hub would be awkward.

Automation angle

T3 stresses that the temperature/humidity unit is not just a glanceable gauge: 0.1°C and 1% RH resolution can drive scenes (run a dehumidifier, nudge a thermostat, alert on freezer drift). Door/window events feeding security alerts are table stakes; the leak sensor’s local voice/audible path is the sleeper feature when your phone is on silent or offline. Still verify which traits expose cleanly to Apple Home, Google Home, Alexa, or Home Assistant before you standardize an entire floor on Meross.

Rocks take

Compelling entry price for a Matter-branded hub kit—especially the leak sensor—if you want local alerts and multi-radio reach without a £100+ controller. Confirm shipping dates (late-September pre-sale windows have been cited elsewhere) and return policy. Source: T3.
