Xiaomi Smart Hub on the phone: hidden features and setup of a smart home through Mi Home

Xiaomi Smart Hub is not a standalone app, but a built-in module in the Mi Home ecosystem that turns your Android smartphone into a central smart home control console. Many users mistakenly search for it in the Play Market or try to install it as a standalone software, but in fact the functionality is already integrated into the official Mi Home app (now Xiaomi Home).

If you notice a Smart Hub in your phone settings or receive a notification that it has been activated, your device supports advanced automation scenarios for Xiaomi, Aqara, Yeelight and other compatible brands. In this article, we’ll look at how it works at the system level, what hidden features are available through Settings → Connected devices, and why some smart devices don’t sync without it.

What is Xiaomi Smart Hub and why you need it on a smartphone

Xiaomi Smart Hub is a software bridge between your phone and smart home devices that provides:

• 🔄 Local control without cloud (even if the internet is down, some scenarios will work over Bluetooth or Wi-Fi Direct).
• ⚡ Quick reaction to triggers (e.g., turning on the light when opening a door takes 0.3–0.5 seconds instead of 1-2 seconds through the cloud).
• 📱 Integration with phone system functions: geolocation, schedule, Do Not Disturb modes and even gestures.
• 🔒 Additional layer of security – some commands are executed directly, bypassing Xiaomi servers.

In practice, this means that you can set up automation like, "If your phone is connected to your home Wi-Fi and after 18:00, turn on the smart lamp and start the robot vacuum cleaner." With Smart Hub, you can monitor the condition locally, without delays in sending data to the cloud.

Important: The Smart Hub is activated automatically when you first connect a compatible device via Mi Home, but for advanced features it needs to be enabled manually in the phone settings.

Smart Hub vs Mi Home: What’s the difference and what’s the best thing to use

Mi Home

Mi Home (now Xiaomi Home) is:

• 📲 The main application for device management.
• 🌍 Cloud sync (works even outside the home).
• 📊 Data history from sensors (temperature, humidity, etc.).

The Smart Hub is:

• 🏠 Local controller (works without the Internet).
• ⚡ Rapid response to triggers (e.g. motion sensor).
• 📱 Integration with phone system functions (geolocation, calendar).

The critical difference is that the Smart Hub does not replace the Mi Home, but expands its capabilities. For example, without the Mi Home, you will not be able to add new devices, and without the Smart Hub, local scenarios will not work.

Security: How to protect your Smart Hub from hacking

Since the Smart Hub runs a smart home, it could become a target for hackers.

• 🔓 Data leakage (e.g. geolocation history).
• 🏠 Unauthorized access to cameras or locks.
• 💡 Sabotage (on/off devices by an attacker).

How to secure the system:

1. Turn off USB Debugging (Settings → About Phone → MIUI Version → 7 times tap → Developer Settings → USB Debugging).
2. Set a password for the Mi Home app (Profile → Settings → Security → Password of the app).
3. Update the router’s firmware (vulnerabilities in older versions are often used to attack IoT devices).
4. Create a separate network for smart devices in your router settings (guest network is not suitable!).

⚠️ Warning: Never connect Xiaomi smart devices to public Wi-Fi networks (such as in a cafe or hotel.
