How to turn on Xiaomi humidifier: the complete guide

Xiaomi’s modern climate systems are complex devices that combine functionality and minimalist design. Users often face difficulties in their first run, as the usual power button can be hidden or have touch control. Understanding the logic of the device is the key to a quick start.

In this article, we’ll explore all the nuances of activating humidifiers from classic Mi Smart Antibacterial Humidifiers to advanced versions of the Pro H series. We’ll look at both physical inclusion and digital tuning through the smart home ecosystem, allowing you to gain maximum control over the indoor climate.

It's important to note that the algorithms can vary depending on the year of release and the specific modification of the device, but the basic principles remain the same, and following proven action algorithms will help avoid errors and prolong the life of the device.

Preparation of the device for the first launch

Before looking for the power button, make sure the device is ready to go.Safety is the number one priority for any electronics. Xiaomi humidifiers are equipped with a sophisticated protection system that blocks startup when built improperly.

First, remove the top cover and remove the water tank. Make sure all transport plugs are removed and the filter element is installed correctly. Often manufacturers pack the filter in polyethylene, which must be removed before use.

💡

Soak the new filter in water for 15-20 minutes before installation – this will improve its absorbency and prolong its life.

Once the filter is installed, fill the tank with clean water. Use distilled or filtered water to prevent scale and white plaque from forming on furniture. Hard water can quickly disable the ultrasonic membrane.

• 💧 Remove the package from the filter and wash it.
• 🔌 Make sure the base is dry before installing the tank.
• 🧩 Close the tank cover tightly until a characteristic click.
• 🔋 Connect the original power cable to the socket.

Only after all the preparatory steps are completed can you proceed to activation, and ignoring the rules of preparation often leads to the fact that the device does not respond to commands or does not work correctly.

Physical Incorporation and Button Management

Xiaomi's humidifier management interface is often hidden. Most models have an on button on the top panel or on the front of the case, which can be touch-sensitive or mechanical. On touch-based models, it requires a short press to activate, and a long retention to change modes.

⚠️ Warning: If the lights flash but the device doesn't turn on, check if the tank lid is tightly closed.

On the Pro series, control is done through a rotary regulator or a hidden touchpad, and the regulator's rotation allows smooth changes in the intensity of the fog, and mechanical buttons require more confident pressing before the sound signal or the indicator lights up.

Once switched on successfully, the power indicator will light up. The color of the glow may indicate the current humidity level or operating mode. For example, green often indicates the optimal humidity level, and red - critically low or the need to replenish water.

Set up through the Mi Home app

To make full use of the smart humidifier, you need to connect it to the Mi Home app, which gives you access to statistics, remote control and voice assistants, and without the app, you lose about 40 percent of the functionality of the device.

Download the Mi Home app (or Xiaomi Home) from the official store. Sign up or log in to your account. Click Add Device button in the top right corner. The app will prompt you to select a device from the list or find it automatically via Bluetooth.

When pairing, it is important to choose the right region, and if your account is registered in Russia and your device is Chinese, it can be difficult, and in such cases, changing the region in the application settings to China sometimes helps, but this can slow down the server response.

Once you've successfully connected, you can set up automatic scenarios, such as the humidifier that can turn on when the humidity drops below 40 percent, or shut down when you leave the house, which saves water and electricity.

Modes of operation and their activation

Modern Xiaomi humidifiers offer several modes of operation. Standard mode supports a constant spray rate. In automatic mode, the device independently adjusts the power, based on the readings of humidity sensors.

Sleep Mode turns off the backlight and reduces noise to a minimum, which is critical for a comfortable sleep, and can be activated by pressing the mode button long enough or through an app.

⚠️ Warning: Do not use Sterilization mode constantly.It heats water to high temperatures, which is safe to kill bacteria, but can be dangerous to children or animals if directly in contact with the ferry.

The flavoring mode is available in models with a special compartment for essential oils. Never pour oil directly into the water tank - it will destroy the plastic parts and membrane. Use only the capsule designed for this.

Switching between modes on the body is usually done by cycling a button, and in the application, the choice is more flexible: you can specify the exact operating time, timer and desired humidity level.

Decoding of indicators and signals

The device communicates with the user through LED indicators, understanding their signals helps to quickly diagnose problems, orange or red flashing indicator most often signals a lack of water.

If the indicator is constantly on red, it may mean that the filter needs to be replaced or cleaned. In the Mi Home application, you can reset the filter resource meter after it is replaced or cleaned, which will return the device to normal operation.

• 🟢 Green: Normal work, humidity normal.
• 🔴 Red: Low water level or error.
• 🔵 Blue: Sterilization regimen or low temperature.
• 🟡 Yellow/Orange: Maintenance or low humidity required.

Some models use digital displays that display the exact percentage of humidity. If error codes (e.g., E1, E2) appear on the screen, refer to the instructions, most often this is solved by restarting the device.

💡

Regular cleaning of the humidity sensor (usually located on the back wall) ensures the automatic mode works accurately.

Frequent startup problems and their solution

Sometimes the device doesn't turn on even if you follow all the instructions, and the first reason is that there's no contact between the base and the tank, and check if there's any condensation at the bottom of the tank that can block the sensors.

The second common problem is software failure. The humidifier can freeze. To solve this problem, disconnect the device from the network for 10-15 seconds, and then turn it on again. This is the performs soft reset system.

Wi-Fi reset sequence:


1. Press and hold the on button and the mode button at the same time.




2. Hold 5-7 seconds until the sound signal appears.




3.The Wi-Fi indicator will start flashing, which means that it is ready to pair.

If the device makes strange sounds or vibrates, check the installation on a flat surface. Ultrasonic membranes are sensitive to vibrations. Also make sure that water does not enter the housing through the vents.
