Fumigator Xiaomi Mijia: how to connect to the phone via Mi Home in 5 minutes

The Xiaomi Mijia Smart Mosquito Repellent is a smart device that not only protects your home from mosquitoes, but also integrates into the Mi Home ecosystem for remote control. However, many users face difficulties when connecting for the first time: the app does not find the device, the indicator flashes differently from the instructions, or the fumigator refuses to work after updating the firmware. In this article, we will analyze all the stages of connection, from installing the application to configuring automatic scripts, and also reveal hidden nuances that are not written in the official manual.

It is important to understand that Xiaomi Mijia releases several modifications of fumigators (for example, DJT11LM or MUE4096GL), and the connection algorithm may be slightly different. We will focus on the universal method that works for most models, but also point out the key differences between versions. If your fumigator is equipped with a Zigbee module (for example, complete with Xiaomi Mi Smart Hub), the integration process will be different - read about this in a separate section.

Before you start, check three critical conditions: 1) The device must be plugged in (the indicator flashes blue or white). 2) Your smartphone is connected to a 2.4 GHz Wi-Fi network (the fumigator does not support 5 GHz!). 3 You have the latest update of the Mi Home app installed (version at least 6.5.400).

If at least one of the conditions is not met, the connection will end with the error "The device does not respond".

1.Preparation: What to do before connecting

The first step is not to press buttons in the app, but to physically prepare the fumigator and the environment, and many people skip this step and then spend hours looking for the reason why the device is not identified.

• 🔌 Check the power: connect the fumigator to the socket. The indicator should flash blue (standby) or white (network search mode). If the LED does not burn, the device is malfunctioning or the power supply is damaged.
• 📶 Set up Wi-Fi: the fumigator works only with networks 2.4 If your router is broadcasting two networks (for example, MyWiFi_2G and MyWiFi_5G), Connect the phone to the first one. How do you check the frequency of the network? Go to the Wi-Fi settings on your smartphone and see the properties of the connection.
• 📱 Update Mi Home: The older version of the app may not support new fumigator models. Go to Google Play or the App Store, find Mi Home and upgrade to the latest version. Minimum working version is 6.5.400.
• 🌍 Choose the right region: when you first launch, Mi Home will suggest you choose a country. For Russia, the optimal option is Russia or Mainland China (if you have a Chinese version of the device!

Critical detail: if your fumigator was previously connected to another Xiaomi account, it must be reset. To do this, hold the button on the case for 5-7 seconds until the indicator flashes quickly white.

⚠️ Note: Some models of fumigators (for example, MUE4096GL) They require a plate with a fumigant to be pre-installed, and without it, the device will not be activated and will not be displayed in the application, and check that the plate is installed correctly, and its contacts must contact the connectors inside the housing.

2. Installation and configuration of the Mi Home app

Mi Home is the central control center for all Xiaomi devices, but its interface is often changed, and in the Russian version some features may be hidden.

1. Download Mi Home: 📱 Android: Google Play 🍎 iOS: App Store

Avoid third-party sources – there are often fake versions with viruses.

Register a Xiaomi account:

If you don't already have an account, click "Register" and provide a valid email or phone number. Importantly, link the account to the same region as the fumigator (e.g. Russia), changing the region after registration will lead to loss of access to devices!

Select the server:

When you first log in, you'll have to choose a server. Russia is the best server for Russia, Mainland China is the best server for China. If you pick the wrong server, some features (like voice control via Alice) may not work.

Set up notifications:

Go to Profile → Settings → Notifications and turn on alerts for new devices. This will help track the connection status of the fumigator.

💡

If you have a Mi Home error, “Can’t send SMS,” try using email instead of phone number, and check if your carrier is blocking messages from international numbers (Xiaomi sends codes from Chinese numbers).

⚠️ Note: If you are using an iPhone with iOS 17+, Before installing Mi Home, go to Settings → Confidentiality → Tracking and allowing the app to access the local network, without which the fumigator will not be able to connect to the phone.

3. Step-by-step connection of the fumigator to the Mi Home

Now, the most important step is to add the device to the app, and follow the instructions carefully, because the order of action is important:

1. Activate Connection Mode: Hold the button on the fumigator body for 3-5 seconds until the indicator flashes white quickly, which means that the device is ready to pair. If the indicator flashes blue, the fumigator is already tied to another account (reset is needed).
2. Add the device to Mi Home: Open the app, click + in the top right corner → select Add device → find Smart Home or Security (depending on the app version). From the device list, select Mosquito Repellent.

• ⏱️ Work timer: set a schedule for on/off (for example, from 20:00 to 6:00) This will save fumigant and electricity.
• 🌿 Mode of operation: Standard - maximum efficiency (plate consumption) ~30 days. Eco - reduced consumption (plastic is enough for ~45 days), but weaker protection. turbo - enhanced mode for open spaces (balconies, verandas).
• 🔄 Automatic firmware update: Turn on this option to get the fumigator new features and bug fixes.
• 📊 Usage statistics: In the History section, you can see how long the device has been working per day / week.
