Your Xiaomi Smart Home Devices Are Powerful Individually — But Disconnected
You've built a Xiaomi smart home piece by piece — smart bulbs, temperature sensors, motion detectors, smart plugs, and perhaps a smart lock or two. Each device works well on its own. But without a central hub to coordinate them, you're missing the real power of a connected home: automations that respond to your presence, scenes that transform your environment with a single tap, and the ability to control everything from anywhere in the world through one unified app.
The Xiaomi Mijia Gateway 4 is the central nervous system your Xiaomi smart home has been waiting for. A next-generation smart home hub that supports Wi-Fi 5GHz, Bluetooth Mesh, and a fast 10/100Mbps wired network port, it brings every compatible Xiaomi and Mijia device under the control of the Mi Home app — giving you the unified, responsive smart home experience that individual devices alone can never deliver.
Why the Mijia Gateway 4 Is a Step Change from Previous Generations
The Gateway 4 represents a significant upgrade over earlier Xiaomi hubs. The addition of 5GHz Wi-Fi support means faster, less congested connectivity in environments where the 2.4GHz band is crowded with neighbouring networks. The 10/100Mbps wired Ethernet port provides a rock-solid, latency-free connection option for users who want the absolute reliability of a physical network connection. And the expanded Bluetooth Mesh support means the gateway can communicate with a wider range of Xiaomi and third-party Bluetooth mesh devices than its predecessors.
Together, these improvements mean the Gateway 4 is not just a hub — it's a future-proof foundation for a smart home that will grow and evolve with you over the coming years.
Bluetooth Mesh: The Protocol That Makes Smart Homes Scale
Bluetooth Mesh is one of the most important protocols in modern smart home technology, and the Mijia Gateway 4's support for it is a key differentiator. Unlike standard Bluetooth, which is point-to-point and limited in range, Bluetooth Mesh creates a self-healing network where each device acts as a signal repeater. This means your smart home network becomes more robust and more extensive as you add more devices — the opposite of the congestion and dropouts that plague Wi-Fi-only smart home setups.
For Xiaomi users, Bluetooth Mesh support means access to a growing library of Mijia-certified devices that use this protocol — smart lighting, sensors, switches, and more — all manageable through the same Mi Home app interface.
The Mi Home App: One Interface for Everything
The Mi Home app is one of the most mature and feature-rich smart home platforms available. Through it, you can create automations that respond to sensor inputs — a door sensor opening triggers the hallway light, a temperature sensor detecting a drop activates the heating. You can build scenes that transform your home's environment with a single tap — a "Movie Night" scene that dims the lights, closes the blinds, and turns on the TV. You can set schedules that align your smart home with your daily routine, and share access with family members so everyone can control the home from their own device.
Remote control functionality means you're never out of touch with your home. Check whether you left a light on. Lock a door you forgot to close. Turn on the heating before you arrive. All of this is possible from anywhere in the world, as long as your phone has an internet connection and requires Android 7.0 or iOS 11.0 and above.
Wired and Wireless — Your Choice
The Gateway 4's dual connectivity options give you genuine flexibility. Connect wirelessly via 2.4GHz or 5GHz Wi-Fi for flexible placement anywhere in your home, or plug in via the 10/100Mbps Ethernet port for a rock-solid, latency-free connection. The wired option is particularly valuable in environments with heavy Wi-Fi congestion, or for users who simply prefer the reliability of a physical connection for their smart home's central hub.
Who This Hub Is For
The Xiaomi Mijia Gateway 4 is ideal for anyone building or expanding a Xiaomi/Mijia smart home ecosystem. If you already have Xiaomi smart devices and want to unlock their full automation potential, this hub is the missing piece. If you're starting a new smart home from scratch and want to build on one of the world's most mature and well-supported ecosystems, this is the foundation to start with. And if you're upgrading from an older Xiaomi hub, the Gateway 4's 5GHz Wi-Fi and expanded Bluetooth Mesh support make it a meaningful step forward.
