How to connect the Xiaomi Smartmi Air Humidifier 2 humidifier to Wi-Fi and Mi Home: full instructions with photo

Why you need a smart humidifier and what Smartmi Air Humidifier 2 can do

The Xiaomi Smartmi Air Humidifier 2 is not just a device to maintain a comfortable microclimate, but a full-fledged element of the smart home ecosystem. Unlike classic models, it allows you to remotely monitor humidity levels, adjust your work schedule and integrate with other Xiaomi gadgets through the Mi Home app (or Mi Home Lite for users from Russia).

The Air Humidifier 2 features ultrasonic spraying, built-in hygrostat to automatically maintain the desired humidity, and aromatization (when using special capsules), but its main advantage is the ability to control via a smartphone, voice assistants (Alice, Google Assistant, Siri via HomeKit), and even scenario automation (for example, turn on when humidity drops below 40%).

However, many users face difficulties in the first connection phase: the device does not find the network, the application does not see the humidifier, or synchronization errors occur. In this article, we will discuss all official and alternative ways of connecting, including solving typical problems.

What you will need to connect the humidifier

Before you start setting up, make sure you have everything you need:

• 📱 Smartphone on Android 6.0+ or iOS 10.0+ with the Mi Home app installed (you can download it from the App Store or Google Play).
• 🔌 Power supply 220V and socket near the humidifier installation site (power cable short - 1.5 m).
• 📶 A stable 2.4GHz Wi-Fi network (the device does not support 5GHz!) The network password must be in Latin (Cyrillic is not supported).
• 💧 Clean water (preferably distilled or filtered) – pour it into the tank before turning it on.

If you are using Mi Home Lite (the Russian version of the app), please note that some features may be limited, for example, Mi Home Lite does not support HomeKit and some automation scenarios.

⚠️ Warning: Do not connect the humidifier to the network via VPN or corporate Wi-Fi with portal authentication (as in hotels).

Step-by-step: Connect to Mi Home

Follow this algorithm to add a humidifier to the app:

1. Install the humidifier on a flat surface (not closer than 30 cm from the walls and furniture) and pour water into the tank to the maximum mark.
2. Connect the device to the outlet - the power indicator (white LED) will light up on the panel.
3. Activate pairing mode: Press and hold the Power button (🔄) on the case for 5 seconds until the indicator flashes orange. If the indicator flashes blue, the device is already in pairing mode.
4. Open the Mi Home app and go to Devices → Add Device (+).
5. Select category: In the search box, type in Smartmi Air Humidifier 2. Or select manually: Smart Home → Humidifiers → Xiaomi Smartmi Air Humidifier 2.

Connect to the humidifier network

• The application will offer to connect to the temporary network smartmi-XXXX (password is not required).
• Once connected, return to Mi Home and search for the device will begin.
• Select your Wi-Fi network and enter your password. Make sure the network is running at 2.4 GHz.
• Wait for the setup to be completed (1-3 minutes). The humidifier indicator should light up blue (successful connection) or red (error).

The humidifier is plugged in and flashes orange.

Wi-Fi runs at 2.4 GHz (turn off 5 GHz in router settings)

Password from Wi-Fi in Latin (without Cyrillic and special characters)

Mi Home app updated to latest version

The device is not further than 2 meters from the router-->

If you have a “failed to connect” error during the Wi-Fi connection phase, try:

• 🔄 Reboot the router and humidifier (pull the plug for 10 seconds).
• 📵 Turn off mobile data and VPN.
• 🔒 Make sure that the network name does not contain spaces or Cyrillic characters.

Set up the humidifier after connecting

After successfully adding the device to Mi Home, configure its settings:

1. Set the device name (e.g., “Bedroom Humidifier”) for ease of control.
2. Adjust target humidity: The optimal level for living spaces is 40-60%. In the nursery, 50-60% is recommended.
3. Activate additional features: 🌙 Night mode – turns off the indicators and reduces noise. 💧 Auto-turn off in the absence of water (on by default). 🔄 Aromatization mode (requires purchase of Smartmi Aroma Capsule capsules).

Set up a schedule.

• For example, turn on 30 minutes before bedtime and disconnect after 8 hours.

In the Automation section, you can create scenarios, for example:

• 🌡️ Insert the humidifier if the Xiaomi Temperature & Humidity Sensor shows humidity below 40%.
• 🛌 Turn off all smart devices in the bedroom by commanding Sleep (via Yandex Alice or Google Assistant).

💡

If the humidifier often turns off due to lack of water, add 1-2 drops of liquid soap to the tank - this will reduce surface tension and improve the spraying of water residues.

Solving Connection Problems

If the humidifier is not connected to the Mi Home, check the following points:

1. The device is not in pairing mode

Symptom: The indicator is white or blue, but does not flash orange.

Decision:

• 🔌 Turn off the humidifier from the socket for 10 seconds, then turn it on again.
• 🔄 Press and hold the Power button for 5-7 seconds until the indicator flashes orange.

2.The application does not see the device.

Symptom: After selecting a model in Mi Home, the search ends with the error "Device not found".

Decision:

• 📱 Reinstall the Mi Home app (sometimes cache cleaning helps).
• 🔗 Connect your smartphone to another Wi-Fi network (e.g., a mobile hotspot), then try again.
• 🌍 Check the region in the Mi Home profile: it must be China (even if you are in Russia).

3. Wi-Fi connection error

Symptom: at the stage of entering a password from the network, a message appears "I failed to connect to the network."

Decision:

• 🔒 Make sure the password is entered without errors (registration is important!).
• 📡 Reboot your router and try connecting to the network from another device (like a laptop) to check if it works.
• 🛠️ In the router settings, turn off MAC-address filtering and guest access.

⚠️ Warning: If the humidifier has previously been connected to another Mi Home account, you need to reset it. To do this, hold the Power button for 10 seconds until the indicator flashes red.

Connecting to voice assistants (Alice, Google Assistant, Siri)

The Smartmi Air Humidifier 2 supports voice control through:

• 🗣️ Yandex Alice (connection to Yandex Smart Home is required).
• 🤖 Google Assistant (via Mi Home + Google Home)
• 🍎 Siri (only if the humidifier is connected to Apple HomeKit via Mi Home in China region)

To connect to Alice:

1. Open the Yandex app with Alice.
2. Go to Devices → Add the device → Xiaomi.
3. Sign in to your Mi Home account and select a humidifier from the list.
4. Name the device (e.g., "humidifier") and save it.

Now you can use commands:

• "Alice, turn on the humidifier by 50%."
• "Alice, turn off the humidifier in the bedroom."
• "Alice, set the humidity level at 45%."

For Google Assistant:

1. In Mi Home, go to Profile → Settings → Google Assistant.
2. Click Add Devices to Google and log in.
3. In the Google Home app, the humidifier will appear in the list of devices.

⚠️ Warning: Voice control only works when the humidifier is connected to the Internet, and if the Wi-Fi goes off, the commands will not be executed.

Update firmware and reset settings

Regular firmware updates improve the stability of the humidifier and add new features to update the software:

1. Open Mi Home and select your humidifier.
2. Go to Settings (⚙️) → Firmware update.
3. If a new version is available, click Update and wait until it is completed (don’t turn off power!).

If the device is unstable (spontaneously shuts down, does not respond to commands), reset to factory settings:

1. Turn off the humidifier from the socket.
2. Press and hold the Power button.
3. Without releasing the button, connect the device to the outlet.
4. Hold the button for another 10 seconds until the indicator flashes red.

💡

Resetting removes all user settings (timetable, device name, humidity settings) and reconnects the humidifier after reset, as when you first use it.

Operation and care tips

To make the humidifier last longer, follow the recommendations:

• 💧 Use distilled or filtered water to prevent scale from forming on the ultrasonic membrane.
• 🧼 Clean the tank and base once a week with a soft brush and vinegar solution (1:1 with water).
• 🌿 Change the water daily, even if the humidifier is not used - this will prevent bacteria from multiplying.
• 🔌 Do not leave the device on without water, as this can damage the membrane.

If the humidifier starts to make noise or spray water poorly:

• Check if the holes are clogged for steam (clean them with a cotton swab).
• Make sure that the membrane is not covered with plaque (if there is a strong contamination, replace it).
• Check whether the device is evenly worth it - vibration when working can be amplified on an uneven surface.

Use only the original Smartmi Aroma Capsule capsules to flavor. Homemade solutions with essential oils can damage the plastic and membrane.
