Modern health gadgets are no longer just weight meters, becoming full-fledged analytical centers. Xiaomi Body Composition Scale 2 (often referred to in the catalogs Mi Body Fat Scale 2) is able to analyze up to 13 body parameters, including muscle and bone mass percentage, making it an indispensable tool for those who monitor physical fitness.
However, to achieve its potential, it needs to be properly synchronized with your smartphone. The setup process may not seem obvious to beginners due to the specifics of the Bluetooth Low Energy protocol and the requirements of the application ecosystem. In this guide, we will detail each step required to successfully launch your tracker.
It is important to understand that the stability of data transfer depends on the version of your phone’s operating system and the correct installation of the software. We will consider not only the standard scenario of connecting via Mi Fit, but also alternative options, as well as methods for solving typical connection errors.
Preparation of the device and necessary applications
Before starting the synchronization procedure, make sure you have all the necessary components on hand: you will need the scale platform itself, three AAA batteries (usually included but require removal of the protective film before first use), and a smartphone with an active Bluetooth 4.0 module or higher.
The software is a key element of the ecosystem, and the main application for working with the device is Mi Fit (renamed Zepp Life in some regions), which is responsible for calibrating, storing the history of measurements and plotting changes in indicators.
Can I use a scale without the Internet?
It is also worth checking in advance for free space on the phone and a stable Internet connection for the initial upload of user profiles. Without authorization in the Mi Account, the functionality of the device will be limited to basic weighing.
- 📱 Smartphone with Android 4.4+ or iOS 9.0+
- 🔋 Three new batteries AAA (Avoiding low-charge errors)
- 📶 Activated Bluetooth module and network access
- 📥 Installed with Zepp Life app (formerly Mi Fit)
Installation and configuration of the Zepp Life app
The process begins with downloading official software.Look for Zepp Life in the Google Play or App Store. Please note that the developer must be specified by Xiaomi to avoid installing third-party clones with limited functionality.
Once installed, start the app and create a new account or log into your existing Mi Account. This is a critical step, as all body composition data will be linked to this profile. When registering, specify the correct height, age and gender data, since fat mass algorithms rely on these parameters.
The profile settings recommend setting weight targets immediately if this feature is available in your version of the software, allowing the system to make more accurate recommendations and track progress in real time, and avoid skipping the permissions phase of the application, especially access to geolocation and Bluetooth.
The interface of the app may vary by region, but the basic logic remains the same. Go to the Profile or Mine tab to see the list of available devices, and that's where new gadgets are found and paired.
Step-by-step instructions for connecting the weights
Now, we're going to go directly to pair the devices, put the batteries in the bottom of the scale, the device has to make a distinctive sound and turn on the display, and you'll see a ready-to-work display on the screen.
Open the Zepp Life app on your smartphone and go to add devices. Click on the plus in the upper right corner or select Add Device from the profile menu. The system will start scanning the surrounding space for available gadgets.
☑️ Checklist of connection
The list of devices found should show Mi Body Composition Scale 2 or Mi Body Fat Scale 2. Click on the model name to start the mating procedure, at which point a flashing confirmation code may appear on the scale screen.
Confirm the pairing on your smartphone screen. It takes no more than 10-15 seconds. Once successfully connected, the scales are automatically calibrated, and you hear a confirmation signal. The device is now ready for the first weigh-in.
It is important to stay within the weights at this point to complete the initial firmware synchronization, if required.The application may suggest updating firmware's weights to improve measurement accuracy.
Decoding indicators and working with data
Once connected, the scales begin to collect detailed statistics. With each weighing, the Xiaomi Body Composition Scale 2 passes a safe microcurrent through the body to assess tissue resistance, and 13 parameters are calculated from this data.
Key metrics include body fat percentage, water content, muscle mass, bone mass, protein levels, basal metabolism and visceral fat, and the visceral fat that surrounds the internal organs and is a marker of health.
| Parameter | Description | Norm (exemplary) |
|---|---|---|
| Percentage of fat | Share of fat tissue in total weight | 18-24% (wives), 12-18% (husband) |
| Muscle mass | Weight of skeletal muscles | Depends on age and height |
| visceral fat | Fat around internal organs | 1-9 (healthy level) |
| Bone mass | Mineral density of bones | 2.0 - 3.5 kg |
All the data is stored in the profile history, and the app lets you track the dynamics of changes by weeks and months, by plotting graphics, and you can share the results with your friends or coach directly from the interface.
💡
For maximum accuracy, weigh yourself at the same time of day, preferably on an empty stomach in the morning and after using the toilet, which minimizes errors caused by food intake and swelling.
If you use scales with the whole family, the app automatically recognizes the user based on weight and measurement history, distributing the data to the appropriate profiles. Guests have a Guest mode, the data of which is not stored in long-term memory.
Integration with Google Fit and Apple Health
One of the strengths of Xiaomi's ecosystem is that it can aggregate data, and you can link Zepp Life to popular health services like Google Fit or Apple Health, and you can see all the activity and health statistics in one place.
To set up, go to the app profile, select Add Accounts or Third Party Services, find the platform you want and log in, and then all weighings will automatically be duplicated into the service you choose.
⚠️ Note: When syncing with Apple Health, make sure you give permission to write data into the Weight and Fat Percentage categories.Without this right, the scales will work, but the data won't appear in the standard Health app on your iPhone.
This integration is especially useful if you use other activity trackers, such as the Mi Band fitness bracelets or the Amazfit smartwatch. Combining your steps, pulse and body composition data gives you a complete picture of your physical condition.
In some cases, you may need to manually reassign accounts after updating the phone's operating system. If sync has stopped, try disabling and reconnecting the service in the app settings.
Solution: Scales are not connected
Despite the ease of setup, users may encounter problems, most often because the scales are not visible in the Bluetooth list or the app cannot complete the connection, often because the device has already been paired with the phone via the Bluetooth system menu.
If the Xiaomi Body Composition Scale 2 is not connected, try removing it from the list of paired devices in your phone’s Bluetooth settings. Then completely close the Zepp Life app and start the search again inside the program, ignoring the system menu.
💡
The main rule of diagnosis: always search for a device strictly inside the Zepp Life app, and not through the standard Bluetooth menu of a smartphone.
Another reason could be a discharged battery. Even if the display lights up, the voltage may not be enough for a stable Bluetooth module.
Also check if the Mi Fit or Zepp Life app is running on another phone that's nearby.Libra can automatically connect to the last active device, blocking your smartphone's connection.
⚠️ Attention: Do not put scales on soft coatings (carpets, carpet). For the correct operation of sensors and calibration, a hard, flat surface (tile, laminate, linoleum) is necessary).
