How to connect Xiaomi humidifier to Mi Home: full instructions with photos and tips

Xiaomi’s humidifier is not just a household appliance, but a full-fledged smart home device that can automatically maintain a comfortable microclimate. However, many users face difficulties when connecting to the Mi Home ecosystem for the first time. Unlike conventional humidifiers, Xiaomi Smartmi or Viomi models require the correct setup through a mobile application, otherwise you will not be able to control them remotely or use functions like automatic humidity maintenance.

In this article, we will discuss the entire process from unpacking the device to solving typical errors (for example, when the humidifier is not identified in the application), paying special attention to the nuances that the manufacturer often misses in official instructions: Selecting the right region in Mi Home, setting up Wi-Fi for devices with limited protocol support and how to reset the device if something goes wrong. 2020–2026 Including Smartmi Air Humidifier 2/3, Viomi Air Humidifier and other compatible devices.

If you’ve tried to plug in a humidifier before, but you’ve encountered an error like “Device is not responding” or “Can’t add,” skip the first two sections and immediately jump to the troubleshooting section. For newcomers to the Xiaomi ecosystem, we’ve prepared a step-by-step guide illustrating the key points.

Preparation before connection: what to check

Before you start setting up, make sure you meet all the prerequisites. 90% of the errors when adding devices to the Mi Home are due to improper preparation, not a malfunction of the equipment.

First, check your humidifier compatibility with the app. Not all Xiaomi models are supported in the Russian Mi Home region. For example, some Viomi devices may require a switch to China (Mainland China) - we will discuss this below. The full list of compatible models can be found on the official website or in the Mi Home directory.

• 📱 Install the latest version of Mi Home. download the app from Google Play or the App Store. Version below 6.0.100 may not support new devices.
• 🌐 Connect to 2.4GHz Wi-Fi. Xiaomi Humidifiers don’t work with 5GHz networks. If your router only broadcasts 5GHz, turn on compatibility mode or create a separate network for smart devices.
• 🔋 Charging and water. Make sure the device is charged (if it's a portable model) and has water in it -- some humidifiers refuse to turn on without liquid.
• 📡 Distance to router: The device must be no further than 5 meters from the router during connection. Thick walls or interference from other gadgets can interrupt the process.

⚠️ Note: If you are using Mi Home in the Russian region, but the humidifier is not on the list of supported devices, do not try to connect it using "Add manually". This can cause a firmware failure).

Choosing a region in Mi Home: why it matters

One of the most common questions is, “Why isn’t my humidifier on the device list?” and the most common problem is the wrong region in the Mi Home app, because Xiaomi is splitting devices by geographic area, and some models (especially from the Viomi sub-brand) are originally designed only for the Chinese market.

To check the current region:

1. Open Mi Home and go to Profile → Settings → Region.
2. If Russia is there, but the device is not, try changing to China.
3. After changing the region, be sure to restart the application and try adding the humidifier again.

If you have switched to China temporarily but want to return the Russian language, after adding the device:

1. Bring the region back to Russia.
2. Delete the app cache (Phone Settings → Apps → Mi Home → Memory → Clear the cache).
3. Go to Mi Home again – the device will remain in the list, and the interface will be in Russian.

💡

If you've lost your humidifier from your device list after you change region, don't panic. Try adding it again through Add Device → Smart Home → Humidifier. This usually solves the problem.

1. Disconnect the device from the network.
2. Pour the water and flush the tank.
3. Pour a solution of citric acid (50 g per 1 liter of water) into the container and turn on the humidifier for 30-60 minutes.
4. After cleaning, wash the tank with clean water 2-3 times.

⚠️ Warning: Never use abrasives or hard brushes to clean, they will damage the ultrasonic membrane. Also avoid chlorine detergents, which can leave a chemical residue that will then be sprayed into the air.
