Modern technology has turned a conventional weighing process into a full-fledged collection of biometric data for health analysis. Xiaomi Mi Body Composition Scale and its modifications have become one of the most popular gadgets in the Chinese giant’s ecosystem due to the affordable price and high accuracy of measurements. However, the initial configuration of the device often raises questions from users who are not familiar with the peculiarities of pairing Bluetooth gadgets.
To work properly, the equipment must not only turn it on, but also properly connect to the mobile device through a specialized application. Errors during the initial synchronization stage can lead to the fact that the gadget will only show weight, ignoring the calculation of fat, muscle mass and other parameters. In this article, we will discuss in detail the process of preparing, installing software and directly connecting the scales to the smartphone.
The setup process takes only a few minutes, but requires a certain sequence of actions. Connection stability depends on the version of your phone's operating system and the correctness of the privacy settings you selected. If you just purchased a device or reset your old one, follow the below recommendations for quick activation.
Preparation of equipment and compatibility check
Before you start software setup, you need to make sure that the device is physically ready to work. Xiaomi Mi Scale 2 and Mi Body Composition Scale 2 scales are powered by four AAA batteries that are not usually included in the package. Install the batteries in the appropriate compartment on the bottom panel, observing the polarity indicated on the diagram.
After the batteries are installed, the device should automatically activate, and the display will briefly show zeros or a brand logo, which indicates that the contacts are serviceable and the elements are charged.
⚠️ Note: Do not use scales on soft surfaces such as carpet or foam. To calibrate strain gauges and properly operate the gyroscope, an exclusively hard, flat surface (tile, linoleum, laminate) is required).
Compatibility is a key factor in successful connectivity. Make sure your smartphone supports Bluetooth 4.0 or newer protocol versions. Most modern Android 5.0+ and iOS 9.0+ devices fully support scale functionality. If you have an old phone, it can see scales like a normal device, but it can't transmit advanced body composition data.
💡
If the scale screen does not light up after installing new batteries, try to slightly press the power compartment cover or spin the batteries to eliminate possible oxidation of the contacts.
Selecting and installing the right application
The centerpiece of Xiaomi’s smart home ecosystem is the software that processes the data it receives. Mi Fit was the main pairing application for a long time, but in 2021 the company rebranded, and now the main platform solution is Zepp Life, which is recommended for new users.
You can download the app from official stores: Google Play for Android or App Store for iOS. In the search box, type "Zepp Life" or "Mi Fit" if you prefer the interface of the old version. After installation, you need to register an account. This can be a Xiaomi account, Google or Apple ID. Registration is required to save your measurement history in the cloud.
There is also an alternative Mi Home app that integrates all smart home devices, but for the Mi Body Composition Scale series, it often works less consistently in terms of biometric detail. For deep body composition analysis, experts recommend a bundle of weights and a Zepp Life app.
- 📱 Download the Zepp Life app from the official store.
- 📝 Register using your preferred method of entry.
- 🌍 Select the "Russia" region or your country of residence when you first launch.
- 🔐 Allow the app to access geolocation and notifications (critical for Android).
The process of pairing weights with a smartphone
The connection is set up directly through the interface of the selected application, rather than through the standard Bluetooth menu of the smartphone. If you try to connect devices first through the system settings of the phone, the application may not see the scales or be unable to transfer data. Open the Zepp Life application and go to the Profile tab in the lower right corner.
In the "My devices" section, click the "Add device" button. The app will start scanning space for available gadgets. At this point, you need to stand on the scale with one foot to activate the pairing mode. The scale screen will start flashing the Bluetooth icon or the "cal" symbol, which means readiness to k.
Once a model of your scales (e.g. Mi Body Composition Scale 2) appears on the list, click on it. Confirm the pairing if the system requests permission. Once the scale is successfully connected, the scales automatically synchronize the time and date, and the smartphone screen displays a message about the successful addition.
Sequence of action:
1. Open Zepp Life -> Profile
2. Press "Add device"
3. Stand on the scale (the screen should catch fire)
4. Select the device in the list
5. Wait for the synchronization to be completed☑️ Checklist of connection
Setting up a user profile for data accuracy
In order to make your calculations of fat percentage, visceral fat and body type correct, the app needs to know your anthropometrics. Without that, the scales will only show body weight. Go to the user profile in the app and fill in all the fields: gender, age, height and physical activity level.
The accuracy of growth input is critical to calculating BMI and other derived measures. If you plan to use scales as a family, you need to create separate profiles for each person. Xiaomi scales support up to 16 users, automatically recognizing them by weight and other parameters after the initial calibration.
You can also set weight goals in your profile settings, which will allow the app to chart progress and make recommendations, and keep the data updated periodically, especially if you're growing up fast or if you've made a significant change in your physical activity level.
⚠️ Note: Do not create profiles with identical weight and height parameters for different people. The scale algorithm can confuse users if their starting weight differs by less than one. 3-5 kilogram.

Decoding of indicators and parameter table
Once you've connected and adjusted the scales, they'll provide advanced statistics, and understanding these indicators will help you manage your health more effectively, and the main method of measuring this is bioimpedance analysis, which lets a safe electrical pulse through your body.
Different tissues in the body conduct current at different speeds, muscles contain a lot of water and electrolytes, so they conduct current well, and fat tissue does not conduct current well, and based on this resistance and the anthropometric data you input, the algorithm calculates the following parameters:
| Parameter | Description | Normal (average) |
|---|---|---|
| BMI (BMI) | Body mass index, weight and height ratio | 18.5 – 24.9 |
| Percentage of fat | Share of fat tissue in total body weight | 10-20% (M), 18-28% (G) |
| Muscle mass | Weight of skeletal muscles in kg | Depends on age and gender. |
| visceral fat | Fat around internal organs (level 1-59) | 1 - 9 (optimum) |
| Bone mass | Bone mineral density in kg | Depends on the build. |
It's worth noting that these can fluctuate throughout the day, and they're affected by the amount of water you drink, the amount of food you eat, the time of day, and the most accurate data comes from the fasting morning after you go to the bathroom, which is the kind of condition that's recommended to track long-term trends.
Solving Common Connection Problems
Despite the simplicity of the procedure, users may face difficulties, most often the problem lies in the access rights of the application. On Android-smons, the Bluetooth scanner in the background necessarily requires an enabled geolocation (GPS). Without this permission, the application simply will not see the scales.
If the scales appear in the phone's Bluetooth list as "coupled" but don't work in the app, try removing the device from the Bluetooth system settings. Then close the app completely (unload from memory) and start the search again. Sometimes it helps to reboot the smartphone itself.
In rare cases, you need to reset the scales to the factory settings. 10-15 And then you put them back in, and then you put them back in, and then you put them back in the original setting, and you can add them as a new device.
- 🔋 Check the battery charge (the indicator on the screen should not flash when weighing).
- 📡 Make sure Bluetooth is enabled and visible to other devices.
- 📍 Enable geolocation in phone settings for the app.
- 🔄 Reinstall the app if the problem persists.
💡
90% of Xiaomi’s weights connectivity problems are solved by enabling geolocation on your smartphone and re-attempting to pair through the app, rather than through Bluetooth settings.
