Why Xiaomi Humidifier Doesn't Connect to Wi-Fi and How to Fix It
The Xiaomi Smartmi Humidifier 2 (ZNJSQ02JM) is one of the most popular smart home devices, but its Wi-Fi connection is often questionable. Even experienced Mi Home users encounter errors like “Unable to connect to the network” or “offline device.” The reasons may lie in router settings, humidifier firmware version, or even in small things like the wrong region in the app.
In this article, we will analyze the step-by-step connection algorithm, taking into account all the nuances from router preparation to solving typical errors. Particular attention will be paid to compatibility with different Wi-Fi standards (2.4 vs 5 GHz), network security settings and bypassing the Mi Home restrictions for users from Russia. If your humidifier is already in a box with the words "Can't connect" - do not rush to return it to the store: in 90% of cases, the problem is solved in 10 minutes.
Critical detail: Xiaomi Humidifier 2 humidifier only works with 2.4 GHz networks and does not support 5 GHz, even if your router broadcasts both bands at the same time.
What you need to connect
Before you start, make sure you have everything you need:
- 📱 Smartphone with installed application Mi Home (version no lower) 6.5.400 for Android/iOS). Important: the Russian version of the application can block some functions – more about this below.
- 🔌 Xiaomi Smartmi Humidifier 2 with a charged battery (if the model is portable) or connected to a socket.
- 📶 Router with 2.4 GHz network (required!) Network name (SSID) It should not contain Cyrillic, spaces or special symbols.
- ⚡ Stable Internet connection (minimum speed: 2 Mbps) If you have mobile Internet, switch to Wi-Fi.
If you have a dual-band router (such as the Xiaomi Mi Router 4A or TP-Link Archer C6), check that the 2.4 GHz network is on and broadcasting separately from 5 GHz. In some routers, these networks are combined under a single name (a Smart Connect feature), which interferes with connectivity.
Step-by-step: Connect to Wi-Fi via Mi Home
Follow the algorithm in strict order, and if you've had a mistake at some point, don't go any further, go back and check the settings.
- Install the Mi Home app. Download it from the official store: 📱 Google Play (Android) 🍎 App Store (iOS)
Note: if you are in Russia, select Mainland China (China) region when registering, this will increase the chances of a successful connection.
Prepare the router.
Go to your router settings (usually 192.168.0.1 or 192.168.1.1) and check:
- 🔒 Type of network encryption: should be WPA2-PSK (not WPA3!).
- 📡 Wi-Fi Channel: Select a fixed channel (e.g. 6 or 11) rather than Auto".
- 🔄 Turn off the Customer Isolation function (if any).
- Add the device to Mi Home. Open the app, click + → Add device and select the category Humidifier. In the list, find the Smartmi Humidifier 2 model (ZNJSQ02JM). If the model is not listed, update the app or try to select "Other device" and manually type the name.
- Connect your smartphone to the humidifier network. The app will request to connect to a temporary network such as "Xiaomi_XXXX". Go to your phone's Wi-Fi settings and connect to it. Go back to Mi Home, and the pairing process will begin.

Table: Common mistakes and their solutions
| Mistake at Mi Home | Possible cause | Decision |
|---|---|---|
| "I couldn't get on the grid." | The router uses 5 GHz or mixed mode (2.4+5 GHz) | Turn off 5 GHz in your router settings or create a separate 2.4 GHz network |
| "Offline Device" after connection | Mi Home region is incorrectly selected (e.g. "Russia") | Remove the device and add again by selecting the "China" region |
| "Incorrect password" (with the correct password) | Type of network encryption: WPA3 or mixed (WPA/WPA2) | Switch your router to WPA2-PSK (AES) |
| The humidifier does not flash when holding the button. | The device is discharged or reset to factory settings | Connect to the socket for 10 minutes, then try again. |
| "Device not responding" in the annex | Blocking Mi Home traffic with router firewall | Turn off firewall or add an exception for domains *.mi.com |
If your error is not listed in the table, try resetting the humidifier to the factory settings. To do this, hold the power button for 10-15 seconds until the indicator flashes red. After reset, repeat the connection procedure.
💡
If you have a router from a provider (such as Rostelecom or MTS), it may block the connection of smart devices. Try temporarily connecting to a mobile hotspot from a phone configured to 2.4 GHz.
Features of connection in Russia and other CIS countries
Users from Russia often face a problem: the humidifier connects to Wi-Fi, but after a few minutes it turns off or does not display current data in the application, due to the limitations of Xiaomi servers for the Russia region in Mi Home.
Decisions:
- 🌍 Change region to China: Remove device from the app. Go to profile ("I" → "Region") and select "Mainland China." Add the humidifier again.
The downside: the application interface will be in Chinese, but the basic functions will remain operational.
alternatives
- Mi Home (Europe) is the region of Germanyy or Spain.
- Aqara Home – if the humidifier is compatible (check the model).
- 🔧 Set up. VPN on the router: Connect the router to VPN-This will fool Xiaomi’s servers into thinking you’re connecting from Asia.
