Introduction: Why link humidifier to Mi Home?
The Xiaomi Smartmi Zhimi Air Humidifier 2 is not just a household appliance, it’s a full-fledged part of the smart home ecosystem. By connecting it to the Mi Home app, you get remote humidity control, schedule adjustments, and integration with other Xiaomi devices (such as climate sensors or voice assistants). Without this synchronization, the device works like a normal humidifier — with mechanical buttons and without analytics.
But the connection process often raises questions: the app doesn't see the device, the synchronization errors occur, it's not clear how to reset the settings. In this article, we'll look at all the steps of the connection, from preparation to solving typical problems, and give tips on how to optimize the operation of the humidifier in the Mi Home ecosystem.
If you have already tried to connect a device and encountered an error (for example, code 10004 or 20001), do not rush to bring it to the service - in 90% of cases, the problem is solved software.
Preparing for connection: what to do before synchronization
Before you start connecting, make sure that the basic conditions are met:
- 📱 The latest Mi Home app is installed (check out Google Play or App Store). Older versions may not support newer devices.
- 🌐 Humidifier and smartphone connected to the same Wi-Fi network at 2.4 GHz. the device does not work with 5 GHz networks!
If your router only supports 5GHz, you’ll have to temporarily switch to 2.4GHz or create a guest network at the desired frequency, and check if the router blocks new devices from connecting (sometimes functions like AP Isolation or MAC Filter do this).
Important: If the humidifier has already been connected to another Mi Home account, it should be reset. To do this, hold the power button for 5 seconds until the indicator flashes quickly. After reset, the device will return to the factory settings.
Install/update Mi Home|

Step-by-step: how to add a humidifier to Mi Home
Now, to the process of connecting, follow the instructions in strict order, and skipping the steps can lead to errors.
- Open Mi Home and log in. If you don't have an account, sign up (use a real email, you'll need it to restore access).
- Connect to a time network. The smartphone will automatically switch to the humidifier access point (the name will be XIAOMI-XXXX type). Return to Mi Home and wait for the sync to complete.
Once successfully connected, the device will appear in the Mi Home main menu, and you can now customize its name (such as “Bedroom Humidifier”) and add it to the main screen for quick access.
💡
If the application freezes during the Connection to the Network stage, try disabling the VPN or antivirus – they can block the connection.
Setting up the humidifier after connecting: hidden functions
Many users are limited to basic settings, but the Smartmi Zhimi Air Humidifier 2 supports advanced options that significantly improve its performance:
- 🌡️ Automotive mode on the humidity sensor. The humidifier will maintain a predetermined level (for example, 50-60%) It's not manually controlled. It's activated in the device's menu. → Settings → Automatic.
- 🕒 Work schedule. You can program the on/off time (for example, at night or when you are not at home). → Timer.
- 🔊 Noise level. Settings are on the menu. → Select Quiet modes for night work (noise level will drop to 30 dB).
- 🌐 Integration with voice assistants. Mi Home allows you to connect the humidifier to Alice, Google Assistant or Siri (you need to enable the option in your account settings).
Note the optional section in the device settings, where you can see options like Child Lock (disables touch buttons) or Sensor Calibration (useful if the humidity readings seem inaccurate).
| Function | Description | Where to turn it on |
|---|---|---|
| Automation in the absence of water | The humidifier will turn off if the tank is empty (overheat protection) | Settings → Security |
| Night mode. | Turns off the lights and reduces noise to a minimum | Settings → Modes → Night Modes → |
| Low water level notifications | The app will send a push when the water is running out. | Settings → Notifications |
| Synchronization with climate sensor | The humidifier will be guided by the readings of an external sensor (for example, Xiaomi Temperature & Humidity Sensor). | Settings → External devices |
Professional advice: if you have multiple Xiaomi humidifiers in your apartment, you can combine them into a group through Smart Scenarios in Mi Home. For example, set up the simultaneous activation of all appliances when the humidity drops below 40%.
Typical errors and their solutions: codes 10004, 20001 and others
Even with the right connection, there are some failures, and let's look at the most common errors and how to fix them:
| Error code | Reason. | Decision |
|---|---|---|
| 10004 | The device is not responding (too far from the router or a weak signal) | Move the humidifier closer to the router or use a Wi-Fi repetitor |
| 20001 | Wrong Wi-Fi Password or 5GHz Network | Check the password, switch the router to 2.4 GHz |
| 40012 | Mi Home servers are overloaded (often in the evening) | Wait 10-15 minutes and try again. |
| 10035 | The device is already linked to another account | Reset the moisturiser (hold the 5 sec button) and reconnect |
If the error does not disappear, try an alternative way to connect:
- Turn off the humidifier from the socket for 30 seconds.
- Turn it back on and hold the power button for 8 seconds right away until the indicator blinks quickly.
- In Mi Home, select Add Manual → Humidifier → Zhimi Air Humidifier 2.
What if the humidifier is connected but does not display humidity?
Attention: ⚠️ If after connecting the humidifier is unstable (it turns off independently, does not respond to commands), check the server region in the Mi Home settings. For Russia, it is optimal to use China (China) - in this case, the device receives the latest firmware.
Firmware Update: Why It Matters and How to Do It
The manufacturer regularly releases updates for Smartmi Zhimi Air Humidifier 2, Those that fix bugs, add new features or improve compatibility with other Xiaomi devices. 2-3 month.
To update the firmware:
- Open Mi Home and select your humidifier.
- Go to Settings → About the device → Update firmware.
- If a new version is available, click Update and wait until it is completed (don’t disconnect the humidifier from the network!).
Warning: ⚠️ If the power or Wi-Fi connection is lost during the upgrade, the device may stop turning on, in which case you will have to do a hardware reset (hold the power button 10 seconds to the beep) and reconnect.
💡
Update your firmware only with stable Wi-Fi and a smartphone charge above 50%. The interrupted process can lead to the "bricking" of the device.
After the update, check all the features, especially automatic mode and integration with sensors. Sometimes new firmware resets individual settings - they will have to be reconfigured.
Integration with other Xiaomi devices: creating a smart climate
Smartmi Zhimi Air Humidifier 2 can be made part of a complex smart home system, such as setting the humidifier to automatically turn on when:
- 🌡️ Humidity sensor (Xiaomi) TH Sensor shows a value below 45%.
- 🚪 Door/window sensor detects closure (useful for bedroom).
- 🛌 The “Sleep” mode is activated in the Mi Home application (the humidifier will go into quiet mode).
To create this scenario:
- In Mi Home, go to Profile → Smart Scripts → Add.
- Select Automation and specify a condition (e.g. Humidity < 45%).
- Add the action: Moisturizer → Enable → Automotive.
- Save the script and activate it.
An example of advanced automation: if you have a Xiaomi Air Purifier, you can set up the two devices to work together. For example, when the purifier is turned on at maximum power (at high dust levels), the humidifier will maintain a humidity of 50% so that the dust settles faster.
