How to connect the Xiaomi Humidifier 2 humidifier to the network and the Mi Home application: full instructions

Xiaomi Smartmi Humidifier 2 (also known as Mi Air Humidifier 2) is one of the most popular smart home devices from Xiaomi. It not only maintains optimal humidity levels, but also integrates into the Mi Home ecosystem, allowing it to be controlled via a smartphone. However, many users have difficulties with the first connection: the device does not find the network, the application does not see the humidifier, or the setup process is interrupted at half.

In this article, we'll look at all the steps of connecting, from unpacking to setting up automatic scripts, how to properly prepare your device, avoid typical Wi-Fi connection errors, and what to do if Humidifier 2 refuses to work with the application, and we'll also talk about hidden features that the manufacturer doesn't always advertise.

If you've just purchased this humidifier or are planning to buy it, bookmark this instruction, which is not only useful for your first connection, but also for resetting or reconnecting to another network.

1. Preparation of the Xiaomi Humidifier 2 humidifier for the first inclusion

Before you connect a device to a network or an application, you have to unpack it properly and prepare it properly, and many people miss this step and then have problems with their work.

Here's what you have to do:

• 📦 Check the package: the box should have a humidifier, power supply, instruction (often in Chinese), and sometimes a spare filter.
• 💧 Rinse the water tank: even if it looks clean, it may still contain dust particles or lubricant from the production. Use warm water and a soft sponge.
• 🔌 Check the integrity of the cable: inspect the power cord for damage. Humidifier 2 is sensitive to voltage surges, so it is better to use a network filter.

Pay special attention to the filter. In some versions of the device, it comes in a separate bag — you have to wash it under running water and put it in place before you turn it on, and if the filter is dry, the humidifier may not start or it will work with an error.

💡

If you have plastic smell after washing the filter, soak it for 10-15 minutes in water with a spoonful of vinegar.

Also check the humidity sensor (a small hole on the body) that doesn't have to be covered by a protective film, it's sometimes forgotten to take off in the workplace, and if the sensor is locked, the device will show incorrect data.

Connecting to the grid: the first steps

Now you can plug the humidifier into the socket, but there are nuances that are not covered in the standard instructions.

Follow this algorithm:

1. Pour the water into the tank to the maximum mark (but not higher!) and use distilled or filtered water to extend the life of the device.
2. Set the tank in place before you click. Make sure it fits tightly to the base, or it will leak.
3. Connect the power supply to the humidifier, then insert the plug into the socket. Do not use extension cords with thin wires - they can overheat when the device is running for a long time.

After turning on the panel, the indicators will light up:

• 🔄 Blinking Blue – the device is ready to be set up.
• 🟢 Green is a normal job.
• 🔴 Red - error (lack of water, filter clog, etc.).

If the indicator does not light up, check:

• 🔌 The density of the connection of the power supply.
• 🔋 Fixed socket (try another device).
• 🛠️ Integrity of cable (sometimes rubbed at the base).

3. Installation and configuration of the Mi Home app

To control the Xiaomi Humidifier 2 via smartphone, you will need the official Mi Home app (also known as Xiaomi Home).

• 📱 Android: Google Play
• 🍎 iOS: App Store

After installation, follow the following steps:

1. Sign up or sign in to an existing Xiaomi account (if not, create one via email or phone number).
2. Select the region of Russia (or your country) – this is important for the correct operation of servers.
3. Click + → Add the device in the upper right corner.

In the list of devices, look for an Air Humidifier (or Smartmi Humidifier 2). If not, try manually entering the name in the search bar.

At this point, many people have a problem when the app doesn't see the humidifier, and the reasons are different.

4. Connecting the humidifier to a Wi-Fi network

This is the most important step. Xiaomi Humidifier 2 connects to the network only at 2.4 GHz – this is important, since many modern routers by default run on 5 GHz.

Instructions for connection:

Make sure the router supports 2.4 GHz|Disable the guest network (it can block devices)|Transfer the humidifier to pairing mode (clip the button for 3 seconds)|Enter Wi-Fi password into Mi Home without errors-->

If your router is running in dual mode (2.4 + 5 GHz with one name, temporarily split the networks in the Marshutter settings:

1. Go to the router control panel (usually at 192.168.0.1 or 192.168.1.1).
2. Find the Wi-Fi or Wireless Mode section.
3. Turn it off. 5 GHz or give different names to networks (e.g., GHz, MyWiFi_2G and MyWiFi_5G).

Once the humidifier is successfully connected, it will beep, and the app will display its current humidity card, and if the process lasts more than 5 minutes, start again.

💡

If the humidifier is connected but falls off the grid after a while, check the energy saving settings on the router. Turn off the "Energy Saving" option for the wireless network.

5.Utilization of the humidifier in the Mi Home app

Now that the device is connected, you can personalize it, and the humidifier card in Mi Home has the following options:

Main settings:

• 🌬️ Operating mode: Auto - maintains the specified humidity. Sleep - quiet mode with minimal brightness of the indicator. Children's - high humidity (good for children's rooms).
• ⏱️ Timer: you can program the on/off schedule.

Additional functions (hidden):

• 📊 Statistics: humidity graphs by day/week (useful for microclimate analysis).
• 🔗 Integration with other devices: for example, the humidifier can automatically turn on when the Xiaomi Thermometer captures dry air.
