Xiaomi Smart Home: What’s Included in the System and How to Build It in 2026

Xiaomi’s smart home ecosystem is one of the most affordable and functional on the market, but its diversity often puts newcomers at a loss. How do you know which devices are really necessary and which can be dispensed with? Where to start assembling a system so you don’t waste money? In this article, we’ll take a look at all the components that make up Xiaomi’s smart home in 2026, from mandatory hubs to optional gadgets for advanced scenarios.

Xiaomi’s key advantage is cross-platform and integration with the Mi Home app (now Xiaomi Home).The system supports not only branded devices, but also many third-party ones through ZigBee, Wi-Fi and Bluetooth Mesh protocols. However, without understanding the underlying architecture, it’s easy to run into compatibility problems or overpay for unnecessary features. Next, you will find a full checklist of devices with current models from 2023-2026, comparison tables and practical tips for building a system for specific tasks – from security to energy saving.

1. Basic components: without which the Xiaomi smart home does not work

Any smart home system starts with a central hub, a device that integrates all sensors and actuators into a single network. In the Xiaomi ecosystem, several types of gadgets play this role, but without at least one of them, most scenarios will not work.

The main functions of the hub:

• 🔄 Routing commands between devices (for example, when the motion sensor is triggered, the light is turned on).
• 📡 Support for protocols: ZigBee 3.0, Bluetooth Mesh, Wi-Fi (depending on model).
• 🔒 Local processing (some scenarios work even without the internet).
• 📱 Integration with Xiaomi Home app and voice assistants (Alice, Google Assistant, Siri).

In 2026, three main hubs are relevant:

• 🏠 Xiaomi Mi Smart Home Hub 2 is the base model with support for ZigBee 3.0 and Bluetooth 5.0. Suitable for most scenarios, but does not have a built-in battery.
• 🔋 Xiaomi Aqara Hub M2 — Extended version with backup power (up to 4 hours without power) and HomeKit support (for Apple users).
• 🎵 Xiaomi Mi Smart Speaker Pro is a hybrid hub and smart speaker with voice control (built-in XiaoAI). Perfect for those who want to control the home by voice.

⚠️ Note: Xiaomi hubs are not compatible with Z-Wave devices. If you already have sensors from other brands (like Fibaro), you will have to use a separate controller or abandon them.

2.Sensors: Eyes and Ears of Your Smart Home

Sensors are triggers that trigger automation scenarios. Without them, the system will be blind: for example, the lights will turn on on on a schedule but will not work when you return home. Xiaomi has sensors for all occasions, but not all of them are equally useful. Consider only those that are actually in demand in 2026.

Top.-5 launcher:

• 🚪 Xiaomi Mi Door/Window Sensor 2 — Magnetic door/window opening sensor. 2 battery-year CR1632. Can be used for intrusion or ventilation alerts.

⚠️ Attention: Battery-powered sensors CR2032 (For example, older versions of the Mi Door Sensor often break down when the battery is replaced. CR1632 or CR2450 — They're more reliable.

💡

If the motion sensor works on pets, reduce the sensitivity in the Xiaomi Home settings or set it above 1.5 meters from the floor.

3.Executive devices: what will execute commands

Sensors collect data, and actuators act on it, such as lamps, sockets, relays, locks, and other equipment that can be controlled remotely or scripted, and Xiaomi's ecosystem has solutions for everything from lights to complex climate automation.

The main categories of actuators:

• 💡 Smart lighting: 🔦 Xiaomi Mi LED Smart Bulb – lamp with adjustable brightness (1-100%) and color temperature (2700–6500K). Consumes 9 watts, equivalent to 60 watts. 🎨 Yeelight Color — RGB-16 million-colored lamp, synchronized with music. 🔆 Xiaomi Mi LED Ceiling Light – ceiling lamp with control of the lighting area (for example, you can turn on only half of the lamps).
• 🔌 Smart sockets and relays: ⚡ Xiaomi Mi Smart Plug - power consumption socket (up to 2200 watts). Supports Wi-Fi. 🔄 Aqara Smart Wall Switch - a switch for hidden wiring (replaces the usual one.
• 🚪 Smart locks and-door: 🔐 Xiaomi Mi Smart Door Lock is an electronic lock with a fingerprint, code and key. 🔓 Aqara Smart Lock N100 — HomeKit-enabled model and time codes for guests.

• 💨 Xiaomi Mi Air Purifier 4 – air purifier with laser sensor PM2.5 and support for Wi-Fi.
• 🌬️ Aqara Smart Radiator Thermostat E1 — Thermostat for heating batteries, allows you to adjust the temperature in each room separately.

Example of scenario:

1. Aqara Temperature Sensor detects temperature drop below 20°S.
2. The hub sends a team to turn on the Mi Space Heater.
3. When opening the window (Mi sensor) Door/Window Sensor) the heater is automatically switched off.
4. When the temperature reaches 22°C, the system goes into maintenance mode.

💡

For effective climate control, place temperature sensors 1.5 meters above the floor and away from direct heat sources (batteries, sunlight).

6.Compatibility and integration with other systems

One of the strengths of Xiaomi’s ecosystem is its compatibility with other platforms, but there are nuances: not all devices work with Google Home or HomeKit out of the box, and some features may be limited.

Opportunities for integration:

• 🍎 HomeKit (Apple): Supported only through Aqara hubs (e.g. Aqara Hub) M2) Not all Xiaomi devices are compatible!
• 🤖 Google Assistant: Works with most devices via the Xiaomi Home app. Voice commands are supported in English and Chinese (Russian limited).
• 🗣️ Alice (Yandex): Integration implemented through the skill "Smart home Xiaomi". Supported basic commands (turn on the light, show the camera), but the scripts do not work.
• 🏠 Home Assistant: Full local automation is possible through Xiaomi Miio plugins or ZigBee2MQTT. Requires customization.

Limitations:

• Xiaomi cameras don’t transmit videos to Google Home or HomeKit – only motion notifications.
• Yeelight smart bulbs only work with HomeKit through a separate Yeelight Bridge hub.
• Voice control in Russian is not supported for all devices (for example, Aqara thermostats understand only English).

7 Automation scenarios: examples for different tasks

The main benefit of a smart home is automation of routine activities. With Xiaomi Home, you can create scenarios based on time, location, sensor data or voice commands. Let's take a few useful examples.

Examples of scenarios:

• 🌅 "Morning Rise: The Yeelight light is turned on at 7:00, with a gradual increase in brightness, the Mi Smart Kettle starts after 5 minutes.
• 🏠 "No one at home: When the last member of the family leaves (by geolocation of the smartphone), all the lights turn off. Security mode is activated: cameras start recording on motion, the siren is ready to go off. Thermostat goes into economy mode (16)°S).
• 🚪 "Coming home": When the front door is opened (Mi Door Sensor sensor), the lights in the hallway turn on. If it's dark outside (Mi Light Sensor data), the lamps in the living room light up. The air conditioning goes into comfortable mode (22)°S).
• 💧 "Water leak: When the Mi Water Leak Sensor is triggered, the electromagnetic faucet is blocked (Aqara Water Valve is required). The phone receives a push notification with a photo from the camera. The siren turns on.

To create scripts in the Xiaomi Home app:

1. Go to the Automation section → Scripts.
2. Press Add Add Add. → User-generated script.
3. Select a trigger (such as a time or event from a sensor).
4. Add actions (turn on the lamp, send a notification, etc.).
5. Save the script and test it out.

⚠️ Note: Geolocation scenarios (coming/going) can be false if your smartphone is turned off Wi-Fi or if you are not using a smartphone. GPS. For reliability, use additional triggers, such as opening a door.

8. Frequent mistakes and how to avoid them

When building a Xiaomi-based smart home, users often face typical problems, and here are the most common mistakes and ways to solve them:

Challenges and solutions:

• 🔌 Devices don't connect to the hub: Check that the hub and device are on the same ZigBee network (not to be confused with Wi-Fi). Update the hub's firmware via Xiaomi Home. Reboot the hub (turn off power for 10 seconds).
• 📶 Unstable Wi-Fi connection: Use a 2.4GHz router (Xiaomi devices often don't run at 5GHz). Turn off Smart Connect in router settings. Place the hub closer to the router (maximum 10 meters without obstacles).
• ⏱️ Scenarios are delayed: Make sure all devices in one region (China/Europe) are in Xiaomi Home settings. Use local scenarios (no cloud) where possible. Check the hub boot - if more than 30 devices are connected to it, buy a second one.
• 🔋 Quick battery discharge in sensors: Replace batteries with quality ones (like Duracell or Energizer); Reduce the frequency of the sensor survey in the settings; check the temperature in the room - at -10°Get off the battery faster.

💡

If the device is no longer responding, try removing it and adding it back to Xiaomi Home first, which solves the problem 80 percent of the time.
