How to set up a Xiaomi air humidifier: a complete guide with photos and tips

Introduction: Why you need the right setup of Xiaomi moisturiser

Xiaomi’s humidifiers are among the most popular devices in the brand’s smart home lineup, combining affordable prices, modern design and extensive functionality, but many users face problems when first connected. Incorrect settings can lead to water overrun, insufficient hydration or even device breakdown. This article will help you understand everything from the basic installation to fine calibration to your needs.

Xiaomi humidifiers are a feature of close integration with the Mi Home ecosystem. Without the right connection to the application, you lose half of the functions: remote control, automatic modes on sensors and synchronization with other devices (for example, with Xiaomi Thermometer).

Important: the instruction is relevant for all modern models - from the budget Xiaomi Smartmi Air Humidifier to the flagship Xiaomi Mi Air Humidifier Pro.

Preparation of the humidifier for the first inclusion

Before connecting a device to a network or application, several mandatory steps must be taken, and neglecting them can lead to malfunctions or activation of protection against misuse.

Start by unpacking and external inspection, make sure the package includes:

• 📦 The humidifier itself with a water tank
• 🔌 Power adapter (usually) 24V/1.5A or 12V/2A — Look at the label)
• 📄 Instructions in Chinese (it can be safely postponed - our guide is fuller)
• 💧 In some models – a special filter or cartridge for water softening

Thoroughly flush the tank|Check the integrity of the sealing rubbers|Install a filter (if included)|Pour distilled or filtered water|Place the device on a flat surface-->

Pay special attention to water quality. Xiaomi’s instructions clearly state that using hard water from the tap reduces the life of the device in the water. 2-3 I've had it because of scale:

• 💧 Distilled water (best choice)
• 🚰 Water after reverse osmosis
• 🔄 Boiled and settled water (at last)

💡

If your area has very hard water, buy a replacement filter cartridge for a humidifier (article). DMF01 It's worth it for most models. ~300₽, It extends the life of the device for years.

After the flood of water do not turn on the humidifier immediately - let the liquid spread through the tank (5-10 This will prevent false alarms from the level sensor.

Connecting Xiaomi Humidifier to the Mi Home app

Without the Mi Home app (or Mi Home Lite for Russia), you can only use basic features.

• 📱 Remote management from anywhere
• 📊 Moisture and water consumption statistics
• ⏱️ Timers and schedules
• 🔄 Automatic scripts with other Xiaomi devices

The connection process is the same for all models, but there are nuances for devices with Wi-Fi and Bluetooth module.

Method 1: Wi-Fi connection (for most models)

1. Download and install Mi Home from the App Store or Google Play.
2. Sign up or sign in to your Xiaomi account (be sure to link your phone number!).
3. Turn the humidifier into the socket and wait for the indicator to blink (usually orange means readiness to pair).
4. In the app, click + → Add the device → Air humidifier.
5. Choose your model from the list (if you’re not sure, take a picture of the sticker at the bottom of the device with the name).
6. Connect your phone to a 2.4GHz Wi-Fi network (5GHz is not supported!).
7. Follow the instructions in the app: it will prompt you to enter a password from Wi-Fi and wait for synchronization.

Method 2: Bluetooth connection for models with BLE)

Some newer models (such as the Xiaomi Smartmi Air Humidifier 2) support Bluetooth Low Energy connectivity, which is simpler but has limitations:

• ✅ It works without Wi-Fi.
• ✅ Fast pairing
• ❌ No remote control outside the home
• ❌ Not all features are available (for example, no data history)

To connect:

1. Turn on Bluetooth on your phone.
2. In the Mi Home app, select + → Add the device → Bluetooth devices.
3. Hold the power button on the humidifier for 3 seconds until the blue indicator flashes.
4. Select the device from the list of found.

Set up the main parameters in the Mi Home application

Once you've successfully connected, you'll open up the humidifier control panel, and let's go through all the key settings that configured costs right away.

The main screen displays:

• 💧 Current humidity level in the room (if the sensor is connected)
• 🌡️ Temperature (if there is a built-in thermometer)
• ⚙️ Current working regime
• 🕒 The remaining working time (if a timer is set)

Click on the icon. ⚙️ in the upper right corner to open the advanced settings:

A critical nuance: if you don't have a separate humidity sensor (like the Xiaomi Temperature and Humidity Sensor), the humidifier will use data from the built-in sensor. ±5-10%, Therefore, for accurate work, we recommend to buy an external sensor (~800₽).

In the Schedule section, you can set up automatic on/off time.

• 🌅 Moisturizing from 6:00 to 9:00 (awakening)
• 🌙 Night mode from 22:00 to 7:00
• 🏠 Intensive hydration from 18:00 to 20:00 (when all at home)

💡

Use the Smart Mode feature if you have other Xiaomi devices (such as a thermostat or window opening sensor).

Manual setting without application (buttons on the case)

If you don't have a smartphone or prefer to control the device directly, all the basic functions are duplicated on the touchpad on the case.The location of the buttons may vary slightly depending on the model, but the overall logic is the same.

A typical control panel includes:

• 🔅 Power button (hold 3 seconds to turn on/off)
• 🌫️ Fog button (intensity switching: weak/medium/strong)
• 🕒 Timer button (cyclical brute force: 1h/4h/8h/⋯)
• 🔄 Mode button (auto/night/continuous)
• 🔒 Lock button (protection from children)

The basic configuration algorithm:

1. Press and hold the power button for 3 seconds until the green light light comes on.
2. By pressing the fog button briefly (🌫️) Select the desired intensity (LED flashes 1 time - weak, 2 times - medium, 3 - strong).
3. Press the timer button (🕒) To set the operating time, the repeated pressing cycles the value.
4. To activate the night mode, press and hold the mode button (🔄) 2 seconds until the indicator is blue.

💡

If the light flashes red, it means there's not enough water. Add the fluid and press the power button to reset the error.

Note that when manually operated, the humidifier does not take into account the current humidity in the room (unless connected to the application) and will run on a timer or continuously, which can lead to excessive humidity.

Advanced functions and automation

The full potential of Xiaomi humidifiers is revealed when integrated with other devices in the ecosystem.

Scenario 1: Automatic humidification at low humidity

If you have a Xiaomi Thermometer sensor:

1. In the Mi Home app, go to Profile → Automation → Create a script.
2. Select the condition: Humidity < 40% (threshold can be changed).
3. Add the action: Humidifier → Turn on → Mode: Auto.
4. Save the script with a clear title (e.g., "Dry Air").

Scenario 2: Shutting down when the window is open

This will require a Xiaomi Opening Sensor Door/Window Sensor:

1. Create a new script.
2. Condition: The window is open.
3. Action: Humidifier → Turn it off.
4. Add a 5 minute delay before turning on after the window closes (to avoid frequent switching).

Scenario 3: Synchronization with the thermostat

If you have Xiaomi Smart Thermostat, you can set up the collaboration:

• When the heating is turned on, the humidifier automatically goes into intensive mode (hot air dries more strongly).
• When turning off the heating - goes into economical mode.

For power users: Mi Home has a hidden Lab feature (not available in all regions).

• 📊 Calibration of the built-in humidity sensor
• 🔧 Protection thresholds
• 📲 Alternative communication protocols (e.g. Matter for HomeKit integration)

Cleaning and maintenance: how to extend the life of a moisturizer

Even the smartest device requires regular maintenance, and neglecting to clean leads to:

• 🦠 Reproduction of bacteria and mold in the reservoir
• 🔊 Increased noise due to scale on the ultrasonic membrane
• 💧 Reduced efficiency of moisture

Recommended service schedule:

1.Plug the solution of citric acid (2 tbsp. per 1l of water).

2. Turn the device on at maximum power for 30 minutes.

3. thoroughly wash all the details.
