Connecting Xiaomi air humidifier to the Mi Home app: full instruction with photos and tips

Introduction: Why connect Xiaomi humidifier to an app?

Xiaomi air humidifiers are no longer just household appliances — today they are full-fledged smart home ecosystem devices that can work automatically, adapt to your habits and even save energy. However, all these features are available only after connecting to the branded Mi Home app (or its Mija counterpart for the European region). Without synchronization, you lose the ability to remote control, integration with voice assistants and advanced automation scenarios.

In this article, we will look at all the steps of connection, from preparing the device to solving typical errors, and pay special attention to the nuances that the manufacturer often misses in official instructions: choosing the right region in the application, setting up Wi-Fi for stable operation, and hidden features that are only available through the Mi Home. If you encounter a problem like “device is not located” or “connection error”, here you will find proven ways to fix them.

Note: The instructions are relevant for all modern Xiaomi humidifier models, including Smartmi Air Humidifier. 2/3, Xiaomi Mi Air Humidifier Pro, Deerma Humidifier (produced under the Xiaomi brand) and others. for outdated versions (for example, the first model). 2016 additional steps may be required, as indicated in the relevant section.

1. Preparation before connection: what should be checked?

Before you start synchronizing, make sure that all the conditions for a successful connection are met. Experience shows that 90% of errors occur due to missed preparatory steps.

Make sure the humidifier is plugged in and running (power indicator is on)

Check model compatibility with Mi Home app (list below)

Connect your smartphone to a 2.4 GHz Wi-Fi network (5 GHz not supported!)

Shut down. VPN, Proxies or corporate networks (they block Xiaomi servers)

Update the Mi Home app to the latest version in the App Store/Google Play

Remove old “ghost” devices from your account (if you’ve previously connected)-->

Pay special attention to the type of Wi-Fi network. Xiaomi Humidifiers only work with 2.4 GHz networks. If your router broadcasts a single network for 2.4 and 5 GHz (for example, with the name MyWiFi without specifying the frequency), try:

• 🔄 Separate networks in router settings (create a separate network for 2.4 GHz with a unique name).
• 📶 Connect to the 2.4 GHz guest network (if any).
• 🔌 Temporarily disable 5 GHz in the router settings (after connecting, you can return back to the router).

Also check the region in the Mi Home app. For Russia, it is optimal to choose Russia (RF) or Europe (Europe) if the first option is not available. Changing the region after connecting the device can lead to its “disappearance” from the list - this is normal, just repeat the synchronization procedure.

2. Step-by-step instruction: connect the humidifier to the Mi Home

Now, to the process itself, follow the instructions in the steps, and skipping even one point can cause a failure, and for convenience, we've broken the process down into three steps: adding the device to the application, physically synchronizing it, and completing the setup.

Step 1: Adding the device to Mi Home

1. Open the Mi Home app and go to the Device tab (the + icon in the upper right corner).
2. Choose the category of Smart Home → Air humidifier (or enter the model name manually in the search bar).
3. Click Add Device and confirm access to geodata (required to determine the region).

Step 2: Synchronization of the moisturizer

This is where the most critical moment begins. Your actions depend on the model.

After activation of the interface mode:

1. Go back to the Mi Home app, which should automatically detect the device. If that doesn't happen, click Device not found? and select Manual Connect.
2. Enter your Wi-Fi password (only 2.4GHz!) and wait until the process is complete. Don't interrupt the connection even if the humidifier light goes out, which is normal for some models.

Step 3: Completion of the setup

After successful connection:

• 📱 The application will offer to update the firmware of the device – agree, this will fix possible bugs and add new features.
• 🏠 Assign a humidifier room (such as a “Bedroom”) to integrate into a smart home scenario.
• ⚙️ Go to the device settings and activate the Autorepress option - this will allow the attacher to automatically maintain a given humidity level.

💡

If the humidifier doesn’t connect the first time, try resetting it to factory settings, holding the power button for 10-15 seconds until the beep (in some models, until all the indicators blink).

3. Common mistakes and their solutions

Even with the exact following of the instructions, there can be failures. TOP-5 Mistakes that users use to support Xiaomi and how to fix them:

⚠️ Note: If the humidifier was previously connected to another Mi Home account, it must first be removed from the old profile, so the owner of the previous account must go to the device settings and select Delete the device. Without this step, the new connection will not be possible.

If neither of these methods worked, try an alternative method of connecting via the Mija app (available for Android).It often works better with Xiaomi's European servers: https://home.mija.cn/.

4.Utilization of the humidifier after connection: hidden functions

After successful synchronization, most users are limited to basic settings, without even knowing the hidden possibilities that the Mi Home app opens.

• 🌡️ Automode: Activate the Auto option in the settings - the humidifier will maintain a given humidity level (optimally 40-60%) without your participation. → Auto and set a target value.
• 🕒 Schedule: Set up a schedule by day of the week, for example, you can start the hydration an hour before bed and turn it off in the morning. → Schedule.
• 🔄 Integration with other devices: Create a scenario where the humidifier will turn on with the air conditioner or air purifier. → Add a script.
• 📊 Usage statistics: In the History section, you can view humidity, operating time and water flow charts, which will help optimize the use of the appliance.

Special attention should be paid to the Children's Mode feature (available in Smartmi Air Humidifier 3), which limits the maximum steam temperature to 40.°C, making the device safe for children's rooms. Activated in settings: Modes → Childhood regime.

For advanced users will be interesting to be able to configure through Mi Home API. It can be used to integrate the humidifier into home automation systems such as Home Assistant or Node-RED. This requires getting the device’s Token through third-party utilities (for example, Mi Home Token Extractor).

💡

The most useful hidden feature is Night Mode, which not only reduces noise levels to 30 dB, but also automatically turns off the backlight of the display, which is especially true for bedrooms, activated manually or on a schedule.

5. Compatibility with voice assistants and other ecosystems

Xiaomi humidifiers support control via voice assistants, but this requires additional customization. Here's how it works for popular platforms:

Management through Alice (Yandex)

For integration with Alice:

1. Open the Yandex app and go to Devices → Add the device.
2. Choose Xiaomi and log in through your Mi Home account.
3. Allow access to the data and wait for synchronization (can take up to 5 minutes).

After that, you can use commands such as:

• “Alice, turn on the humidifier in the bedroom.”
• "Alice, set the humidity to 50%."
• "Alice, turn off the humidifier in an hour."

Managing through Google Assistant

For Google Home:

1. In the Google Home app, click «+» → Set up the device → There are devices already?.
2. Select Xiaomi Mi Home and sign in to your account.
3. Assign a room humidifier (should match the name in Mi Home).

Important: Google Assistant supports only basic commands (on/off, humidity setting) and scripts and schedules are customized exclusively through Mi Home.

Integration with Apple HomeKit

Officially, Xiaomi humidifiers do not support HomeKit, but you can get around this restriction using a bridge (for example, Home Assistant or Aqara Hub).

1. Install Home Assistant on the Raspberry Pi or NAS.
2. Add Xiaomi Mi Home integration through HACS.
3. Get the device’s Token and enter it into the configuration file.
4. Set up export to HomeKit through the homekit component.

⚠️ Note: When using third-party bridges (such as Mi Home Bridge), your Xiaomi account details may be compromised. Use only proven open source solutions such as Home Assistant.

6. Update firmware and reset settings

Regular updates to the humidifier firmware correct errors, add new features and improve stability. You can check the relevance of the software in the Mi Home application:

1. Open the device card and go to Settings → About the device.
2. Press firmware update (if the button is active, a new version is available).
3. Confirm the installation and wait until the completion (do not disconnect the humidifier from the network!).

If after the update the device began to work incorrectly (for example, does not respond to commands or shows incorrect humidity), reset to factory settings:

• 🔧 For Smartmi Air Humidifier 2/3: Hold the power button 10 seconds before the beep.
• 🔧 Xiaomi Mi Air Humidifier Pro: Press and Hold Mode + Mist 5 seconds.
• 🔧 For Deerma Humidifier: Press the Power button for 15 seconds (indicator blinks 3 times).

After the reset, you'll have to reconnect the device to the Mi Home, and if the problem persists, try rolling back the firmware to the previous version.

1. Download the desired version of the software from the official forum Xiaomi (Firmware section).
2. Unpack the archive and rename the file to humidifier_fw.bin.
3. Place the file in the root of the microSD card (if your model supports the upgrade from the memory card).
4. Insert the card into the humidifier and hold the Mode button for 3 seconds to start the update.

7. Optimization of work: operating tips

To make the humidifier last longer and work more efficiently, follow these recommendations:

• 💧 Water: Use only distilled or filtered water. Tap water contains salts that settle on the heating element and shorten the life of the device. If there is no distilled water, boiled water is the worst option (boiling salts does not remove salts!).
• 🧼 Clean: Wash the tank and base of the humidifier once every 3 days with a weak solution of vinegar (1:1 with water).This will prevent mold and bacteria from forming. For models with ultrasonic spraying (for example, Smartmi Air Humidifier 3), use special cleaning tablets.
• 📍 Location: Install the device on a flat surface at least 30 cm from walls and furniture. Avoid direct sunlight and heat sources (such as batteries) - this distorts the humidity sensor readings.
• ⚡ Power consumption: Enable Energy Saving (if available) in the Mi Home settings, which will reduce your energy consumption by 15-20% without losing efficiency.

For models with a warm steam function (for example, Xiaomi Mi Air Humidifier Pro) it is important to:

• Do not direct the flow of steam to furniture or wallpaper – this can lead to their deformation.
• Use the mode only in well-ventilated rooms (for example, in combination with supply ventilation).

If the humidifier starts to make more noise than usual, check:

• 🔊 Fan: It may have been hit by debris. Clean the blades with compressed air.
• 💦 Water level: At low level, the pump works with increased load.
• 🔋 Power: Try connecting the device to another outlet - voltage surges are possible.

💡

Optimal humidity for health is 40-60%. Below 30%, the mucous membranes dry out, above 70%, the mold breeding environment is created, and you can set up automatic maintenance of this range in Mi Home.
