The integration of smart home ecosystem devices into a single network often raises questions among users, especially when it comes to a bunch of gadgets from different manufacturers. Samsung Galaxy smartphone owners who want to use the analytical scales Xiaomi Mi Body Composition Scale or Mi Smart Scale, faced with the need to properly configure the software for data transfer. Synchronizing these devices allows not only to weigh, but also to track the dynamics of changes in body weight, percentage of fat, muscle mass and other parameters directly in the interface of your phone.
The connection process does not require deep technical knowledge, but it is critical to follow the sequence of actions, since the data transfer protocols over Bluetooth Low Energy (BLE) have their own characteristics of the Android operating system. The key point is to use the official Mi Fit application (or Zepp Life) as the main gateway through which data enters the cloud server and becomes available on the smartphone. Direct connection through the standard Bluetooth menu of Samsung Galaxy settings without the use of specialized software is impossible, since the scales transmit an encrypted data stream that is understandable only by the proprietary algorithm.
In this guide, we will take a detailed look at all the steps involved in preparing, installing the software you need, and solving typical compatibility problems, how to ensure a stable connection, how to set up automatic health transmission, and calibration and initial setup ensure that measurements are accurate throughout the life of the device.
Preparation of equipment and software
Before the pairing procedure, you need to make sure that all the components of the system are ready to work. Xiaomi scales usually come with already installed batteries, but with prolonged storage, the charge could be lost. For the Mi Body Composition Scale 2 series, 4 AAA batteries are required, which must be inserted into the appropriate compartment on the bottom panel, observing the polarity. After installing the batteries on the front panel, the Mi logo should light up, indicating the device’s readiness for operation.
Samsung Galaxy smartphone must meet the minimum system requirements for the correct operation of the Xiaomi ecosystem applications. It is recommended to use the Android operating system version at least 6.0, although Android 8.0 and higher is better suited for current weight models. Make sure the phone has Bluetooth enabled and geolocation access is allowed, as modern versions of Android scanning BLE-Devices require activation GPS-location-detection.
⚠️ Note: Do not try to connect scales directly through the standard Bluetooth menu in the Samsung Galaxy settings. The device may appear in the list of available, but data transfer without authorization in the application will not work, and manual pairing can block further automatic synchronization.
An important step in preparation is to download the right software. Xiaomi has used different names for its fitness app at different times. It was formerly known as Mi Fit, but after rebranding and combining with the Huami ecosystem (now Zepp), the app has become known as Zepp Life. For new users and devices, it is most relevant to use Zepp Life, as it receives regular security updates and improved support for new scale models.
Installation and configuration of the Zepp Life app
Finding and installing an app is the first step to building your digital health profile. Open the Google Play Store on your Samsung Galaxy device and search for “Zepp Life.” Make sure that the developer is identified by Anhui Huami Information Technology to avoid installing fake or modified versions of the software. Once downloaded and installed, launch the app and accept the terms of the user agreement.
The next step is to register an account, you can use your existing Xiaomi account, WeChat or re-register using an email address or phone number. Creating a user profile is a must, because the algorithms for calculating body composition (fat percentage, visceral fat, protein level) are based on the data you enter: height, age, gender and current physical fitness. Mistakes at this stage will lead to incorrect calculations, so take the questionnaire as carefully as possible.
The app settings must provide all the permissions you request. The Android system on Samsung smartphones can limit the background work of applications to save energy, so it is important to find the Apps section in the phone settings, select Zepp Life and allow autorun, background operation and access to location data. Without these permissions, scales will not be able to transfer data to the phone if the application is closed.
💡
For owners of Samsung Galaxy with a shell One UI, it is recommended to add the Zepp Life app to the list of "Unlimited" in the battery settings, so that the system does not close the synchronization process.
Once you have completed the initial configuration of the application interface, go to Profile and make sure that all personal data is up to date. These are the parameters that will be used by the scales to conduct bioimpedance analysis. If a family plans to use scales by several people, everyone should create their own profile in the application, but the device is linked to one main account.
The process of pairing the scales with the phone
Now that the software is ready, you can go directly to connect the hardware part. Put the scales on a hard, flat surface (carpet coatings can distort the readings of pressure sensors). Stand on them with one foot to activate the screen, but do not stand with two legs fully while the search process is underway. The scale screen should appear flashing Bluetooth icon or reset symbol, which indicates the pairing mode.
Open the Zepp Life app on a Samsung Galaxy smartphone. Go to the Profile tab at the bottom menu, then scroll down to the Add Device section or click on the plus in the top right corner. From the list of available devices, select your scale model, such as the Mi Body Composition Scale 2 or Mi Smart Scale 2. The app will start searching for the device using the BLE protocol.
Once the scales are found, a pairing request will appear on the smartphone screen. Press "Connect." At which point the scales may show a confirmation code or simply an indication of a successful connection. Once successfully tied, the scales automatically sync the current time with the phone, which is important for maintaining the weighing history.
☑️ Checklist of successful connection
Once connected, you need to do the first test weigh, stand on the scale barefoot, evenly spread your body weight on both feet, stand still until the results appear on the scale screen, and a notification pops up on the phone screen about the receipt of new data, and if the data is displayed in the application, then the transmission protocol is working correctly.
Setting up user and guest profiles
One of the key features of Xiaomi’s smart scales is the ability to recognize up to 16 different users, which is implemented by creating profiles in the application. The main user (the account owner) is automatically configured. To add family members, you need to go to the weight settings in the application and select “Add user” or “Guest mode”.
Each new profile requires you to enter individual parameters: gender, age, height. Libra uses this data to calculate bioimpedance. When a person stands on a platform, the scales analyze their weight and approximate body resistance, compare this data with the stored profiles, and automatically determine who owns the current weighing. The accuracy of the determination depends on the uniqueness of each user's parameters.
| Parameter | Description of the impact on calculations | Where to change |
|---|---|---|
| Growth | Critical for calculating BMI and fat percentage | User profile in Zepp Life |
| Age. | Affects metabolic age and body composition norms | User profile in Zepp Life |
| Paul | Determines formulas for calculating muscle and adipose tissue | User profile in Zepp Life |
| Figure type | Adjusts calculations for athletes or seniors | Weight settings in the appendix |
There's also a "Guest Mode" that allows you to weigh yourself without linking data to a specific profile and without saving a story, which is convenient if you have friends, but for full health tracking, it is recommended to create separate profiles for all regular users.
Why can the scales confuse users?
Integration with Samsung Health and other services
Many Samsung Galaxy smartphone users prefer to use Samsung Health’s native app to track activity. Unfortunately, direct synchronization between Zepp Life and Samsung Health out of the box doesn’t exist due to ecosystem competition.
One of the most reliable methods is to use third-party converter apps, such as Health Sync or Synchronize for Xiaomi, which act as a bridge: they read data from Zepp Life (or directly from the Mi Cloud) and transfer it to Samsung Health. To set up this channel, you will need to install an application converter, log in to it through your Xiaomi account and give permission to write data to Samsung Health.
When setting up sync, it is important to choose the right direction for data transfer. You usually choose the schema: Libra -> Zepp Life -> Health Sync -> Samsung Health. In this case, all the weighings will automatically appear in your phone's standard health application, and you will be able to see a single picture of activity and nutrition.
⚠️ Note: When using third-party sync applications (Health Sync and analogues), you are giving your biometric data to a third developer.
Integration with Google Fit is also possible, which can sync with many other platforms, and the settings of the Zepp Life app itself sometimes feature the option of connecting to Google Fit, which is the most secure and official way to expand functionality without using suspicious software.
💡
For full integration into the Samsung ecosystem, use the Zepp Life -> Health Sync -> Samsung Health bundle to provide automatic weight updates in the native app.
Diagnostics and solution (FAQ)
In the process of operation, there can be situations when the scales stop synchronizing or show a connection error. Most often the problem lies in the energy-saving algorithms of the Android operating system. The system can “sleep” the Zepp Life application, breaking the connection with the scales. To avoid this, you need to go to the battery settings of the phone, find the application and select the “No restrictions” or “Optimize” mode (depending on the version of One UI), and also fix the application in memory (do not close the swip).
Another common problem is time desynchronization. If the scales are out of sync, the weighing history can be saved with the wrong date. To solve this problem, just open the Zepp Life app when Bluetooth is on, the time will automatically update on the scales when you connect. If that doesn't help, try re-inserting the batteries and then repeat the pairing procedure.
If the scales are "Lo" or flashing, it's a low-power signal. Even if the scales are still working, the Bluetooth module can be unstable at low voltage, resulting in loss of data packets when transmitted to a Samsung phone. Always use high-quality alkaline batteries, as salt counterparts quickly lose charge under load.
In rare cases, a complete reset to factory settings may be required. For Xiaomi models, this is usually done by simultaneously clamping the reset button (if any) or a special sequence of actions described in the manual of a particular model.
💡
If the scales stopped seeing the phone after the Android update, try the Bluetooth settings of the phone's "Forget" scale device, then completely remove the scales from the Zepp Life app and perform pairing again.
