Xiaomi Smart Home: A Complete Guide to Build and Setup

How to start building a Xiaomi smart home

Xiaomi's ecosystem offers one of the most affordable and functional solutions for home automation, but before buying sensors and sockets, it's important to understand the key principles: device compatibility, communication protocol (ZigBee/Wi-Fi/Bluetooth) The central hub that will manage the entire system.

Xiaomi’s main advantage is cross-platform: most devices work through a single Mi Home app (or Xiaomi Home in newer versions). However, there are nuances: for example, the Aqara series sensors require a separate Aqara Hub, and some devices (like Yeelight) have their own applications but integrate into the overall ecosystem. Without a ZigBee hub (like Xiaomi Mi Smart Home Gateway), you will not be able to connect door opening, movement or leak sensors – they work only through this protocol.

If you are a beginner, start with a minimum set:

• 📱 Smartphone on Android/iOS with the Mi Home app
• 🔌 Smart socket (for example, Xiaomi Mi Smart Plug) for remote control of household appliances
• 🔦 Smart Lamp (Yeelight or Mi) LED Smart Bulb for lighting
• 🚪 ZigBee (Xiaomi Mi Smart Home Gateway 3)

Device Choice: What to Buy for Basic Automation

Xiaomi ecosystem has hundreds of devices, but enough to start 5-7 The rule of thumb is, give priority to ZigBee-enabled devices that are more stable than Wi-Fi analogues and don't overload your home network.

Here is the best set for an apartment area 50-70 ²:

⚠️ Note: If you plan to use Aqara devices (such as leakage sensors or buttons), buy an Aqara Hub instead of a Xiaomi Gateway.

For advanced automation, add:

• 🌡️ Aqara Smart Radiator Thermostat for heating control
• 💧 Aqara Water Leak Sensor for the bathroom and kitchen
• 🔊 Xiaomi Mi Smart Speaker for voice control
• 📺 Smart TV (Mi) TV Mi Home support for centralized management

Installation and connection of the Xiaomi Mi Smart Home Gateway hub

The hub is the brain of your smart home, and without it, ZigBee devices (sensors, buttons, some switches) won't work. 10-15 minutes, but there are critical nuances:

1. Hub location: place it in the center of the apartment, at a height 1.5-2 Avoid metal surfaces and thick walls, which will screen the ZigBee signal, optimally on a shelf or wall in the hallway.

2. Network connection: the hub requires constant power (included) and connection to the router via Ethernet. Wi-Fi version of the hub (Gateway 3) is unstable - use the cable!

Step-by-step:

1. Connect the hub to the outlet and router via Ethernet.
2. Open the Mi Home app, click on it. + → Add the device → Gateway.
3. Choose the region of China – it is important for the correct operation of sensors!
4. Press the button on the hub when the app asks to confirm the connection.
5. Wait for the firmware update (it can take up to 10 minutes).

⚠️ Note: If the hub is not connected, check:

• 🔌 Power: The indicator should be orange (load) or blue (work).
• 🌐 Network: Turn it off VPN Check that the router does not block ports 80 and 443.
• 📱 Region: If China is not selected, some sensors will not be recognized.

Connecting devices to the hub and setting up in Mi Home

Once the hub is installed, you can add other devices.The process is universal for most Xiaomi gadgets, but there are exceptions (for example, Yeelight requires its app to initially set up).

The general connection algorithm:

1. Open Mi Home, press + → Add the device.
2. Select a category (e.g., Sensors and switches for Motion Sensor).
3. Activate the device: Sensor: Remove the battery film (if any). Sockets: hold the button 5 seconds until the indicator flashes. Lamps: turn on / off 3 times in a row.

Wait for confirmation in the appendix.

⚠️ Note: If the device is not located, check:

• 🔋 Power: Sensors require batteries (usually) CR2032 or AAA).
• 📶 Distance: Maximum distance between hub and device — 10-15 meters (no obstacles).
• 🔄 Reboot: Reboot the hub and router if the connection freezes.

Once connected, the devices will appear in the Mi Home main menu, where you can:

• 📛 Rename (e.g., "Bedroom Lamp" instead of "Bedroom Lamp "Yeelight_123").
• 📊 Set up notifications (for motion/open sensors).
• ⏱️ Create timers (for example, turn off the socket at night).
• 🔗 Grouping in groups (for example, all lamps in the living room).

💡

To speed up the connection of multiple devices, use the “Quick Add” mode in Mi Home: go to Profile → Settings → Laboratory → Quick addition of devices.

Creating Automations (Scenes and Rules)

The main advantage of a smart home is the automation of routine activities. In Mi Home, this is done through Scenes and Automation.

• 🎭 Scene – a set of manually triggered actions (e.g., “Evening Mode” turns off the lights and turns on the TV).
• ⚙️ Automation – the “if... then...” rule (e.g., “if the motion sensor is triggered, turn on the lights").

Examples of useful automation:

How to create automation:

1. In Mi Home go to Automation → Create → If...
2. Select a trigger (such as a motion sensor). → Traffic detected).
3. Click Add Action and select the device (e.g. Yeelight) → Turn on).
4. Keep the rule and test it.

💡

For stable automation, turn off battery optimization for the Mi Home app in Android settings (or enable background update on iOS).

⚠️ Warning: Avoid cyclical automation (e.g., “if the lamp is on, turn off the socket, and if the socket is off, turn on the lamp”). This leads to looping and overloading the hub.

Integration with voice assistants (Alice, Google, Siri)

Smart home Xiaomi can control voice through Yandex Alice, Google Assistant or Apple HomeKit (with restrictions).

Connection to Yandex Alice:

1. Open the Yandex app with Alice.
2. Go to Devices → Add the device → Xiaomi.
3. Enter the username/password from your Mi Home account (use the same region as in the hub!).
4. Allow access to the devices.

Now you can use commands:

• 💡 "Alice, turn on the light in the living room"
• 🔌 "Alice, turn off the kettle socket"
• 🌡️ "Alice, what's the temperature in the room?"

⚠️ Note: Not all Xiaomi devices are supported by Alice. For example, Aqara sensors may not be displayed. For a full list of compatible devices, see Yandex documentation.

Connection to Google Assistant:

1. In the Google Home app, click + → Set up your device → Are there devices already?
2. Select Xiaomi Mi Home and sign in.
3. Assign room devices (for example, "Bedroom", "Kitchen").

Advanced Features: Home Assistant and Local Management

The Mi Home app is convenient for basic settings, but has limitations:

• 🌐 Xiaomi Cloud Dependence (Device Fails in Case of Server Failure).
• ⏳ Delays in execution of commands (up to) 1-2 seconds).
• 🔗 No complex automation (e.g. time of day and weather).

The solution is the Home Assistant platform, which allows you to manage devices locally and create complex scenarios.

The advantages of Home Assistant:

• 🏠 Local control: devices work even without the Internet.
• ⚡ Instant response: teams are executed for 0.1-0.3 seconds.
• 📊 Advanced analytics: power consumption graphs, sensor response history.
• 🤖 Integration: support 2000+ devices, not just Xiaomi).

How to connect Xiaomi to Home Assistant:

1. Install Home Assistant on Raspberry Pi or NAS (Instructions: Official website).
2. In the configuration file configuration.yaml add: xiaomi_aqara: gateways: - key: YOUR_GATEWAY_KEY (The key can be obtained through Mi Home with this tool).
3. Reboot Home Assistant and add devices to the interface.
