How to connect Xiaomi humidifier to iPhone via Wi-Fi: instructions with and without a password

Xiaomi air humidifiers (such as Mi Smart Antibacterial Humidifier or Smartmi Evaporative Humidifier 2) have become an integral part of the smart home ecosystem, but connecting them to iPhones via Wi-Fi often raises questions. The main problem is that the device does not accept a password from the network, gives an error “failed to connect” or freezes during the pairing stage. In this article, we will discuss all the ways of connection, including bypassing typical errors, resetting, and alternative authentication methods.

Xiaomi humidifiers use the Mi Home protocol (now Mi Home App or Xiaomi Home), which sometimes conflicts with iOS security settings. 802.11r (Fast Roaming or using WPA3, We tested the solutions on iPhone 12-15 models with the latest versions of iOS and found working circuits.

Important: If the humidifier was previously connected to another phone (for example, on Android), it must first be reset to the factory settings, otherwise the iPhone will not be able to detect it.

1. Preparation of the humidifier and iPhone for connection

Before setting up, make sure that the basic conditions are met:

• 📱 iOS version is at least 14.0 (older systems may not have drivers for the Mi Home protocol).
• 🌐 Wi-Fi router works in the 2.4 GHz band (Xiaomi humidifiers do not support 5 GHz).
• 🔋 The humidifier is connected to the network and is in pairing mode (flashing the indicator).
• 📲 Xiaomi Home App is installed and authorized (download in App Store).

If the humidifier is new, it automatically goes into pairing mode when you first turn on. If the device has already been used, reset: hold the power button for 5-7 seconds until the indicator flashes quickly orange (in some models, blue).

⚠️ Note: If your router uses a hidden Wi-Fi network (SSID It's not broadcasting, the humidifier can't connect to it, make the network visible temporarily, or set the device up through another access point.

2. Step-by-step instruction: Connect via Xiaomi Home

Follow the algorithm to avoid errors:

1. Open the Xiaomi Home app and go to Devices section → Add the device (+).
2. Select the Humidifiers category and the specific model (if not listed, select Another).
3. Confirm the flashing indicator on the humidifier (click the Indicator flashes quickly).
4. Select your Wi-Fi network from the list and enter your password. There is often an error here - read the solution in the next section.
5. Wait until it's finished (up to 2-3 minutes), and if the light goes blue, the connection is successful.

If at the stage of entering the password, a message appears "I was unable to connect to the network", check:

• 🔄 Router mode: turn off WPA3, Just leave it. WPA2-PSK.
• 📶 Wi-Fi Channel: Set a fixed channel (e.g. 6 or 11) rather than Auto.
• 🛡️ Firewall/antivirus: temporarily turn them off on the router.

Shut down. WPA3 (leave WPA2-PSK)|

Install a fixed 2.4 GHz channel|

Disable the "Fast Roaming" function" (802.11r)|

Reboot the router after the changes-->

3. Solving the Wi-Fi Password Problem: 5 Working Ways

If the humidifier does not accept the password, try these methods:

Method 1: Entering a password manually (without copying)

Some users encounter a bug when a password copied from the clipboard fails to pass. type it manually, avoiding Cyrillic characters or special characters (!@#$% sometimes cause disruption).

Method 2: Using a guest network

Create a guest network with a simple password (e.g. 12345678) on your router and connect the humidifier to it. Once you have successfully set up, return the main network.

Method 3: Changing the region in Xiaomi Home

Go to the application profile (Profile) → Settings → Region and select China, sometimes it solves compatibility issues, and once connected, you can reclaim your region.

Method 4: Connecting through an Android device

If you have an Android phone nearby, plug in the humidifier through it, and then reconfigure the Xiaomi Home app on your iPhone by logging into the same account.

Method 5: Alternative Application (Mi Home Lite)

Install Mi Home Lite (available in the App Store) – it has a simplified interface and sometimes works better with iOS.

⚠️ Note: If the humidifier was previously linked to another user’s Mi Account, it must be removed from the previous profile. → Profile → Devices, select a humidifier and press Remove.

4.Urgent settings after connection

After successful pairing, the device will appear in the main menu of Xiaomi Home.

• 💧 Set a humidity target (40–60 recommended%).
• ⏱️ Start a timer (for example, 8 hours at night).
• 🌡️ Activate the Auto mode if the model has a hygrostat.
• 🔄 Set up a schedule by day of the week.

For models with antibacterial filters (for example, Mi Smart Antibacterial Humidifier) additional options are available:

• 🦠 Ultraviolet cleaning (included manually or on schedule).
• 💨 Adjustment of the steam direction (if supported).
• 📊 Monitoring the filter resource (the application will remind you of the replacement).

Xiaomi humidifiers with Apple HomeKit support (such as some versions of Smartmi) can be integrated directly into the Home app on the iPhone. To do this, after connecting to Xiaomi Home, click Add to HomeKit and scan. QR-device-code.

💡

If the humidifier does not hold the desired humidity, check the location of the sensor. It should be at least 0.5 m from the walls and furniture, and not be directly exposed to steam (for example, if the device is next to the radiator).

5. Typical errors and their correction

Let’s discuss the most frequent failures and ways to eliminate them:

Error: "Device offline" after connection

Reasons:

• The router blocks Xiaomi traffic (check settings) MAC-filtering).
• The humidifier overheated and switched off (wait 10-15 minutes).
• Xiaomi server failure (check status at status.mi.com).

Solution: Reboot the router and device, then re-add it to the app.

Error: "Incorrect Wi-Fi password" (although the password is correct)

It's about encoding characters. Try this:

• Replace your password with only Latin letters and numbers (no passwords!@#$%).
• Shut down. WPS router.
• Use the access point from your phone (enable modem modem on your iPhone).

Error: Humidifier does not respond to commands from the app

Possible causes:

• The device is connected to another network (check in the Wi-Fi settings on the iPhone).
• Xiaomi Home App Selects Wrong Room (Move Device to Home) → Edit).
• Sync failure (exit your account and log in again).

6.Security: How to protect the humidifier from hacking

Xiaomi’s smart devices are sometimes targeted by hackers to minimize the risks:

• 🔐 Use a complex password for your Mi Account (at least 12 characters with letters, numbers and special characters).
• 🌍 Disable remote access if you are not using control from outside the home (Device settings) → Remote control).
• 🔄 Regularly update the firmware (check in Xiaomi Home) → Device profile → Update).
• 📵 Create a separate network for IoT devices (set up) VLAN router).

If you suspect that the device is compromised (e.g., it turns on itself), do:

1. Reset to factory settings (hold the 10 seconds button).
2. Change your Wi-Fi password and Mi Account.
3. Checking Active Sessions in Xiaomi Home → Profile → Security.

⚠️ Warning: Never connect the humidifier to public networks (such as in a cafe or hotel) This may lead to a leak of your Xiaomi account details.

💡

The most common vulnerability is the default password for Wi-Fi (such as admin or 12345678).

7. Alternative ways to control without Wi-Fi

If the connection to the network is not possible, the humidifier can be controlled:

Bluetooth (for supported models)

Some devices (such as Smartmi Evaporative Humidifier 2) support Bluetooth Low Energy (BLE). For that:

1. Turn on Bluetooth on your iPhone.
2. In Xiaomi Home, select Add Manually → Bluetooth.
3. Bring the phone to the humidifier at a distance of up to 1 meter.

Limitation: Control is only possible within a 10 meter radius.

Through the remote control (if included)

Xiaomi Smartmi Air Humidifier models sometimes come with IR remotes. Download the Mi Remote app (available in the App Store), add the remote as a device and control the humidifier through it.

Home Assistant (for advanced users)

If you are using the Home Assistant smart home system, integrate the humidifier through the Xiaomi Miio component:

# Configuration for Configuration.yaml


fan.xiaomi_miio:




host: IP_devices




token: YOUR_MIIO_TOKEN




model: zhimi.humidifier.ca1

To get token, use the Miio-Cli utility.
