Connecting Smartmi air humidifier to Mi Home: a complete guide with tips and life hacks

Why Smartmi Humidifier Doesn't Connect to Mi Home and How to Fix It

Xiaomi Smartmi Air Humidifier is one of the most popular devices in the Xiaomi smart home ecosystem, but connecting it to the Mi Home app often raises questions among users. Even if you are an experienced owner of Xiaomi equipment, the synchronization process can stall during the search for a device, authorization or firmware update. In this article, we will analyze all possible connection scenarios, from basic settings to solving non-standard errors that are not described in the official documentation.

Feature of Smartmi humidifiers (for example, Smartmi Air Humidifier models) 2/3 Smartmi Evaporative Humidifier is a protocol called Zigbee to communicate with a hub or directly with a smartphone via Wi-Fi. This means that the connection algorithm will vary depending on whether you have a Xiaomi Gateway or you are setting up your device in Direct Connection mode. We will look at both options, and also tell you how to get around typical errors like “Device not found” or “Can not add».

Important: If you have previously tried to connect the humidifier and encountered a problem, first perform a complete reset of the device (press the power button for 10 seconds before the indicator flashes) - this will remove all previous settings and allow you to start the process again.

What Smartmi Humidizers Support Mi Home

Not all humidifiers from Smartmi (a brand owned by Xiaomi) are compatible with the Mi Home app. Here is the current list of supported models for 2026:

• 🔹 Smartmi Air Humidifier 2 is the most common model with support for Zigbee and Wi-Fi. Works both through the gateway and in direct connection mode.
• 🔹 Smartmi Air Humidifier 3 - An improved version with a humidity sensor and automatic regulation. Requires firmware at least 1.4.5.
• 🔹 Smartmi Evaporative Humidifier – evaporative humidifier with Mi Home support, but only through Xiaomi Gateway.
• 🔹 Smartmi Air Humidifier JSQ06 — Budget model for the Chinese market (may require a change of region in Mi Home).

If your model is not listed, check its name on the box or in the documents. Humidifiers without the label "Mi Home Ready" or "Works with Mi Home" probably do not support connection to the Xiaomi ecosystem. Devices for the Chinese market (with suffix) CN) may require a change of server in the application.

Preparing for the connection: what to do before the start

Before you start syncing your humidifier with Mi Home, follow the mandatory preparatory steps, and ignoring them is the main cause of 70% of connection errors.

Make sure the humidifier is charged (the indicator is green)

Download the latest version of Mi Home (App Store/Google Play)

Connect your smartphone to a 2.4 GHz Wi-Fi network (5 GHz not supported)

Disable VPN and proxy on your phone

Remove the humidifier from the package and remove protective films from the sensors-->

Pay special attention to Wi-Fi networks: Smartmi humidifiers only work with 2.4 GHz networks. If your router broadcasts a single network for 2.4 and 5 GHz (for example, “MyWiFi” without splitting), temporarily divide it in the router settings or connect to a guest network with only 2.4 GHz support.

• 📶 Name of the network (SSID) It does not contain Cyrillic or special symbols (e.g., "Apartment 123!") Use only Latin and numerals.
• 🔒 Wi-Fi password is no longer than 32 characters and contains no spaces.
• 📱 Power saving modes are disabled on the smartphone (they can block the background work of Mi Home).

If you already have other Xiaomi devices (like Yeelight light bulbs or sensors), make sure they are connected to the same Mi Account you plan to link the humidifier to.

💡

If the humidifier was previously connected to another Mi Home account, reset via the app: go to Profile → Devices → [Your humidifier] → Settings → Remove the device.

Step-by-step: Wi-Fi connection (without gateway)

This method is suitable for Smartmi Air Humidifier models. 2/3 and other devices that support Direct Connection:

1. Turn the humidifier on and wait until the indicator starts flashing orange (standby mode).
2. Press the power button for 5 seconds until the indicator starts to flash blue quickly (pairing mode).
3. Open Mi Home, go to the Devices tab» → «Add the device» (+).
4. Select the category "Humidizers" and find your model in the list. If it is not, select "Other Humidizer".
5. Confirm your Wi-Fi connection (the application will request access to geodata – allow).
6. Wait for the process to be completed (the indicator on the humidifier should light up green).

If you see a “failed to add” error during the device search phase, try:

• 🔄 Reboot the router and smartphone.
• 📱 Delete the cache of the Mi Home app (in Android settings: Apps) → Mi Home → Memory. → Clear the cache).
• 🌐 Change the region to “China” (even if you have a European model).

Once you've successfully connected, the humidifier will appear on the device list. Update the firmware if the app suggests it, and it will fix any bugs in the work.

Connection via Xiaomi Gateway (gateway)

If you have a Xiaomi Gateway (like Mi Smart Home Gateway 3), you can connect the humidifier through it.

• 🔄 Automation according to scenarios (for example, turning on the humidifier when humidity drops below 40%).
• 📊 Integration with other sensors (thermometers, hygrometers).
• 🔌 Stable connection (Zigbee is more reliable than Wi-Fi in the face of interference).

Algorithm of connection through the gateway:

1. Make sure the gateway is connected to the network and is lit blue (standby mode).
2. Transfer the humidifier to pairing mode (press the power button for 5 seconds before blinking blue).
3. At Mi Home, go to Devices» → «Add the device» → «Through the lock».
4. Select your gateway from the list and wait until it finds the humidifier (can take up to 2 minutes).
5. Confirm the addition and assign the device a room (e.g., “Bedroom”).

If the lock does not find the humidifier:

• 🔌 Reconnect the gateway to the socket (sometimes a physical reboot helps).
• 📡 Check the distance between the gateway and the humidifier – it should not exceed 10 meters without obstacles.
• 🔄 Update the gateway firmware (in the device settings in Mi Home).

Once connected, the humidifier will appear in the gateway device list, and you can control it via Mi Home or voice (if you connect it). Alice/Google Assistant).

💡

Connecting through a gateway is more reliable than Wi-Fi, but requires the purchase of an additional device (Xiaomi Gateway).If the humidifier is your first gadget in the Xiaomi ecosystem, it is easier to use Direct Connection mode.

Common mistakes and their solutions

Even with the correct instructions, users are faced with errors, and we have collected the most common problems and ways to fix them:

If neither of these methods worked, try connecting the humidifier through the alternative Xiaomi Home app (available for Android).It is updated more often and supports more devices, especially for the Chinese market: https://home.mi.com (Use an interpreter if you don’t know Chinese).

⚠️ Note: If the humidifier has previously been connected to another gateway or account, it must first be removed from the old network. To do this, in Mi Home, go to the device settings and select "Delete." Without this step, the new connection will not be possible.

Set up the humidifier after connecting

Once synchronized successfully, the humidifier will appear on the Mi Home device list, and can now be customized to suit your needs:

• 💧 Mode: Select Auto (automatic humidity maintenance), Manual (set the level yourself) or Sleep (quiet night mode).
• 📊 Targeted humidity: recommended range 40-60% for children and allergic people can be increased to 65%.
• ⏱ Timer: Set an on/off schedule (e.g. 22:00 to 7:00 for night mode).
• 🔄 Automation: Create a scenario that will include a humidifier when humidity drops below a predetermined level (requires a Xiaomi humidity sensor).

For models with flavoring (for example, Smartmi Air Humidifier 3), an additional option will appear in the settings "Aromacapsule", where you can adjust the intensity of the smell and set a schedule for aromatherapy.

If the humidifier supports voice control, connect it to Alice (Yandex) or Google Assistant:
