How to Manage Xiaomi Humidifier: From Basic Customization to Advanced Features

Xiaomi’s humidifiers have long been an integral part of the brand’s smart home ecosystem, combining affordable price, modern design and wide functionality. However, many users use the device only 30-40% of its capabilities, limited to basic modes. Meanwhile, the proper management of Xiaomi’s humidifier allows not only to maintain an optimal microclimate, but also save energy, extend the life of the device, and integrate it into automated smart home scenarios.

In this article, we will discuss all the ways to manage Xiaomi humidifiers, from classic models like Mi Air Humidifier 2 to flagship solutions like Smartmi Evaporative Humidifier 2. You will learn how to connect the device to the Mi Home application, set up a work schedule, use voice assistants (Alice, Google Assistant, Siri), and solve typical problems faced by owners.

1. Connecting Xiaomi Humidifier to the Mi Home app

The first and most important step is synchronizing your device with the Mi Home mobile app (renamed Mi Home for the international version or Xiaomi Home for the Chinese market), without which you won’t be able to use remote management, schedule settings or integration with other smart home devices.

The connection process is the same for most models (Mi Air Humidifier Pro, Smartmi Air Humidifier, etc.), but there are nuances for Bluetooth Mesh-enabled devices (for example, MiJia Humidifier CA1).

  • 📱 Install Mi Home from Google Play or App Store.
  • 🔌 Connect the humidifier to the network 220V Make sure the power indicator is blue or green (depending on the model).
  • 📲 In the app, click + → Add the device → Air humidifier and select your model.
  • 🔄 Hold the power button on the device body 3-5 seconds until you hear a beep (or a Wi-Fi light flashes).
  • 📶 Connect to the device’s temporary Wi-Fi network (the name will be type) Xiaomi_XXXX) and go back to the app.
  • 🔑 Select your 2.4GHz home Wi-Fi network and enter your password.Please note: Xiaomi Humidifiers do not support 5GHz networks!

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

If the humidifier is not connected, try:

  • 🔄 Reboot the router and smartphone.
  • 📵 Shut down. VPN or a proxy on the phone.
  • 📡 Move the device closer to the router (walls and furniture may block the signal).
  • 🔧 Reset the humidifier settings (hold the power button for 10 seconds until a double beep is made).
What if the Mi Home can’t see the device?
If the app doesn’t find the humidifier, try: 1. Remove the device from the list in Mi Home (if it already has one) and start connecting again. 2. Check if your model supports work in your region (some devices, such as the MiJia Humidifier CA1, are officially sold only in China and require you to change the region in Mi Home to China or Mainland China). 3. Update the router’s firmware – older versions can block the connection of new IoT devices.

2. Control through physical buttons on the body

Even without a smartphone, the Xiaomi humidifier can be controlled using touch or mechanical buttons on the body, their location and functionality depend on the model, but the general logic remains:
