MEROSS MSH450PROMA Smart Wireless Gateway

The Meross MSH450PROMA Smart Wireless Gateway is a device designed to connect and control compatible accessories within a smart home. It supports Bluetooth Low Energy (BLE), 433 MHz radio communication and the Matter standard, allowing the integration of older and newer Meross devices into a single system. It is compatible with popular platforms such as Apple Home, Google Home, Amazon Alexa and Home Assistant, and provides access to voice control and automation. It also offers a communication range of up to 150 m, local control, device migration function and personalized voice notifications.

Stable connectivity and support for various devices

The gateway uses two communication protocols – Bluetooth Low Energy and 433 MHz RF – which allows you to connect various types of Meross sensors and accessories into a single system. The range of up to 150 m allows you to communicate with devices located in different parts of the home. The updated platform offers up to 200% faster data processing speed compared to the MSH450 model. In addition, the gateway has passed more than 10,000 connection stress tests, confirming its ability to operate stably with multiple devices.

Substance integration and local control

Thanks to support for the Matter standard, the gateway allows you to integrate compatible Meross accessories into your chosen smart home ecosystem. Users can create automations and issue voice commands via compatible platforms. Local communication reduces reliance on cloud services, promoting faster device response times and improving privacy. An additional convenience is the one-touch migration feature, which allows you to transfer previously connected accessories from an older gateway to a new one without having to re-pair them.

Customized voice alerts

The Meross MSH450PROMA offers customizable voice messages that notify household members of events detected by compatible sensors. For example, when a smoke detector is triggered, the gateway can play a message that identifies the type of hazard and the room where it was detected. This provides users with more information than just an audible alarm, making it easier to quickly assess the situation. The device is also equipped with a standard audible alarm.

Compact design and easy installation

The gateway measures 76 × 76 × 26 mm, so it can be easily placed on a shelf, table or cabinet. It uses a 2.4 GHz Wi-Fi network (IEEE 802.11 b/g/n) and supports setup via smartphones with iOS 16.1 or later and Android 8.1 or later. An LED indicator shows the device's operating status, and a built-in button makes it easy to use. Double-pressing the button within 2 seconds activates pairing mode, and holding it for 5 seconds resets to factory settings.

It is important to know

When choosing, in addition to the connection method, it is important to consider whether the hub will work with the devices and systems you already use or plan to use. Therefore, before purchasing, check compatibility and choose a location where Wi-Fi and a power outlet are available.

• Please check compatibility for specific devices and their ecosystem; the smart hub label alone does not confirm which devices you can connect.
• The planned location affects the setup: you need access to your home Wi-Fi network and the ability to plug in a power adapter.
