Modern technology has made it possible to turn a conventional weighing process into a full-fledged health monitoring tool. Xiaomi smart scales have become the de facto standard for those who monitor their weight, but their initial setup often raises questions for beginners. Properly connecting the device to a smartphone is a key step, without which the gadget will remain just a glass plate with numbers, without transmitting valuable data about body composition.
In this article, we will discuss in detail the process of synchronizing the Mi Smart Scale 2 model with mobile devices based on Android and iOS. You will learn not only about basic Bluetooth connection, but also about the intricacies of customizing user profiles, which is especially important for family use. A deep understanding of the operation of bioimpedance analysis algorithms will help you get the most accurate results every time.
Errors in the initial calibration phase can lead to measurement errors that will persist for a long time, so it is crucial to follow the sequence described below and take into account environmental factors. We will look at typical connection scenarios, possible application conflicts and ways to quickly resolve them without going to the service center.
Preparation for the first launch and installation of software
The main tool for working with the Xiaomi ecosystem is the Mi Fitness application (formerly known as Mi Fit), which acts as an intermediary between the weights and cloud storage, processing the data received. You can download the application from official Google Play stores or the App Store, avoiding third-party resources.
Once installed, you will need to register for a Mi Account or log in through an existing profile, which is a requirement because all your personal data, including height, age and gender, will be used for calculations. Without these parameters, the analysis algorithm will not be able to correctly calculate the percentage of fat or muscle tissue.
⚠️ Warning: Make sure your smartphone has Bluetooth and geolocation enabled (GPS). In modern versions of Android, access to the location is necessary for the operation of the Bluetooth device scanning protocol, without this scale may not be determined in the list of available devices.
It is also important to prepare the scales themselves. The Mi Smart Scale 2 model is powered by four AAA batteries, which usually come with a complete set. Before installing the batteries, it is recommended to wipe the contacts in the compartment with dry cloth to ensure a reliable connection. Once turned on, the device goes into pairing mode, as signaled by a flashing indicator or the appearance of a logo on the display.
☑️ Readiness for synchronization
The process of pairing weights with a smartphone
Direct configuration starts with the launch of the Mi Fitness app. In the main menu, you need to go to the Profile tab and select Add Device. The system will offer a list of available gadgets, where you should select the Libra category and find the Mi Body Composition Scale 2 model in the list.
When you search for a device, you should use one foot to activate the display and amplify the Bluetooth signal. Once the smartphone detects the scale, a request for confirmation of pairing appears on the screen. Press "Connect" and wait for the procedure to be completed, which usually takes no more than 10-15 seconds.
- 📱 Open the application and go to the user profile.
- 🔍 Click "Add device" and select scales from the list.
- 🦶 Stand on the platf with one foot to activate.
- ✅ Confirm the conjugation in the window that appears.
Once successfully connected, the scales will automatically update their firmware if a new version is available, a process that is critically important as manufacturers often release patches that improve measurement accuracy and connection stability.
💡
If the scales are not in the app, try to completely close the background Mi Fitness processes and start the search again, pre-turning off and turning on Bluetooth on the phone.
Setting up a user profile for accurate data
For a bioimpedance analyzer to work properly, weights need accurate anthropometric data, the application must specify your gender, date of birth, height and level of physical activity, and an error in indicating growth even a few centimeters can significantly distort the calculation of the percentage of fat and muscle mass.
Special attention should be paid to setting the “Target Weight” setting, which allows the application to plot progress and motivate you to achieve results. Xiaomi algorithms use this data to personalize recommendations, so the more honest you specify the input data, the more useful the analytics will be.
| Parameter | Impact on calculations | Recommendation |
|---|---|---|
| Growth | Key to BMI and body composition | Point to exactly 1 cm |
| Age. | Affects metabolism | Update after DR |
| Paul | Different formulas for calculating fat | Check at registration |
| Activity | Calorie expenditure at rest | Choose the real level |
If the scale is used by the whole family, you should not create one common profile. The application allows you to create separate profiles for each family member, which provides individual statistics. Switching between users occurs automatically: the scales recognize the person by weight and parameter ratio, suggesting you choose the desired profile on the smartphone screen.
Decoding indicators and working with the application
After weighing, the smartphone displays a data set that goes far beyond your normal weight, and the percentage of fat tissue is one of the most important metrics, which is calculated based on tissue resistance to electrical current, and muscles contain more water and conduct current better than fat, which is what sensors detect.
And you'll also see visceral fat, which is around the internal organs, which is more dangerous than subcutaneous fat because it directly affects the risk of cardiovascular disease, and in the app, this is usually indicated by a scale of 1 to 59, where values above 10 require attention and nutrition.
⚠️ Attention: Bioimpedance measurements may be inaccurate immediately after exercise, eating or drinking large amounts of water.
The History tab in the app allows you to track the dynamics of change, and you can see not only the weight chart, but also the changes in muscle mass and bone tissue, and it helps you understand what exactly causes the change in body weight — whether it's burning fat or losing muscle, which often happens with rigid diets.

Solving frequent connection problems and errors
Despite the simplicity of the technology, users can face difficulties, and the most common problem is that the scales show weight but do not transmit data to the phone, often because other applications that intercept Bluetooth are running in the background, or the communication module itself is getting stuck.
Another common case is the message “Device is busy,” which means that the scales are trying to connect to another phone that previously logged in to your account, or the sync process was interrupted earlier, in which case a full reboot of the Bluetooth module on the smartphone helps.
- 🔄 Reboot your smartphone and scales (remove the batteries for 10 seconds).
- 📡 Remove the device from the list of conjugated in Bluetooth settings.
- 🔋 Check the battery charge – a weak charge reduces the signal power.
- 📱 Reinstall the Mi Fitness app if the problem persists.
If the scales show an error of "Err" or unstable numbers, check the surface of the installation. The device must stand on a hard, flat floor. Carpet coating, soft-backed linoleum or sloping floor will lead to incorrect readings of pressure sensors.
💡
90% of connection problems are solved by completely removing the weights from the phone’s Bluetooth menu and re-binding through the app from scratch.
