Modern health gadgets are no longer just body weight meters, becoming complex analytical centers. Xiaomi smart scales are able to estimate the percentage of fat, muscle mass, water and even bone tissue, transmitting data directly to the smartphone. However, in order for the device to work correctly and produce accurate results, you need to properly perform the initial adjustment and synchronization with the manufacturer’s ecosystem.
Many users are struggling with the first switch on, not understanding why the gadget is not visible in the application or why the indicators seem inaccurate. Often the problem lies in the nuances of Bluetooth connection or choosing the wrong software. In this article, we will discuss in detail the process of activating the Mi Body Composition Scale 2 and newer models so that you can get the most out of the purchase.
It's important to understand that calibration is done automatically when you first weigh, but only if you've met all the conditions of use. If you're not fitting properly on the floor or if you're not using a battery, you can distort the data, and you can have a lot of confusion in your progress schedules. Let's look at how to avoid the typical mistakes and set up the device in just a few minutes.
Preparation for the first launch and installation of power cells
Before trying to connect the Xiaomi Mi Scale to a phone, you need to provide the device with a source of energy. Unlike many other gadgets, these scales do not have a built-in battery and run on replaceable batteries, which greatly increases their battery life. Usually the kit includes four AAA batteries, but sometimes the manufacturer can only put demo samples that quickly discharge.
Turn the device over and open the battery compartment at the bottom of the case. It's critical to be polar when you install the cells: plus should match plus and minus minus should match the pattern inside the compartment. If you confuse polarity, the device won't turn on, and in the worst case, there might be a short circuit or electrolyte leakage.
⚠️ Warning: Do not use old, partially discharged batteries with new ones, which can cause sensors to malfunction and display errors that users often perceive as a device defect.
Once the batteries are installed, the device will automatically go to standby mode, and the display may show zeros or calibration symbols, which is normal behavior of the system, and the platform is now ready to pair, but until it transmits data, until you do the binding through the mobile application.
Selecting and installing the right synchronization application
One of the most confusing things for beginners is the choice of software. For a long time, the main application for the ecosystem was Mi Fit, but Xiaomi is gradually moving all devices to the Zepp Life platform (formerly known as Mi Fit) and Xiaomi Wear. For scales of the Mi Body Composition Scale 2 series and newer models, it is recommended to use Zepp Life, as it provides the most stable operation and full functionality.
Download the app from the official Google Play store or Apple App Store. After installation, start the program and create an account if you do not already have one. Signing in through Google or Apple accounts significantly speeds up the registration process. From the profile menu, find the add-on section and select the category Libra.
- 📱 Make sure your smartphone has Bluetooth and geolocation enabled (GPS).
- 🔋 Check that the phone screen is unlocked while searching for the device.
- 📶 Do not connect scales through the system settings of the Bluetooth phone, only through the application!
When the app starts searching, stand with one foot on the scale platform to activate them. The scale display should light up a Bluetooth icon or flashing indicator. The name of your model, such as the Mi Body Composition Scale 2, will appear on the list of available devices in the app.
Calibration process and first weighing
Once you've successfully paired, you need to do the first weigh-in, which also serves as the primary calibration procedure for the sensors. To get reliable data, the Bioimpedance algorithm must count the resistance of your body tissues. Stand on the scale with your bare feet, spreading the weight evenly on both feet.
The display will show the current weight, and then, after a short pause, the smartphone screen will show detailed data about the body composition. If you use a model with support for multiple users, the system will suggest creating profiles for each family member. User identification is automatically based on weight and measurement history, so it is important that the first weighing of each person was done correctly.
☑️ Checklist of proper weighing
It is worth noting that to activate all the functions of body composition analysis (fat, muscle, water), the scales must contact the server. So make sure that when you use your smartphone for the first time, you have an active Internet connection. Without the Internet, the scales will only show body weight, but they will not be able to calculate the percentage of fat.
Interpretation of indicators and work with data
The data are not just numbers, but a comprehensive assessment of your body's health: Body Fat Percentage shows the ratio of fat mass to total body weight; for men, 10-20% is the norm; for women, 18-28%, but these values can vary depending on age and body type.
Another important parameter is visceral fat, which is the fatty tissue surrounding the internal organs of the abdomen, and is considered more dangerous to health than subcutaneous fat, since it directly affects the risk of cardiovascular disease and diabetes, and Xiaomi scales this indicator on a scale of 1 to 20, where values above 9 require attention.
| Indicator. | Description | Norma (men) | Norma (women) |
|---|---|---|---|
| Fat mass | Total percentage of body fat | 10-20% | 18-28% |
| Muscle mass | Mass of skeletal muscle | 38-45% | 28-35% |
| Water in the body | Percentage of liquid | 50-65% | 45-60% |
| Bone mass | Mineral density of bones | Depends on the weight. | Depends on the weight. |
And scales also calculate the basic metabolism (BMR), the number of calories your body burns at rest, which is useful for dietary measurements, and all of these data are stored in history, allowing you to track the dynamics of week over week or month over month.
Why can the numbers change throughout the day?
Set up profiles for multiple users
Xiaomi's smart scales support multiple-person storage (typically up to 10-16 users) through an in-app profile system. When you add a new user, the system assigns a unique identifier to them, and each time you weigh the scales, they compare the current weight to the saved profiles and automatically select the right one.
For the Guest mode to work properly or automatically switch, it is necessary that the weight difference between users is significant (more than 5-7 kg). If the scales are used by people of the same weight, automatic determination may fail, in which case it is better to use manual selection of the profile in the application before weighing or the Guest mode function.
⚠️ Warning: Guest mode does not store measurement history in long-term memory or build charts. Use it only for one-time weighings of visitors.
To add a child, create a separate profile with age and height, which is important because the algorithms for calculating children are different from the adult norms. Without accurate anthropometric data (height, age, sex), the calculation of fat percentage will be incorrect.
Error Resolving and Troubleshooting
Even with the right setup, there can be situations where the scales stop synchronizing or show an "ERR" error. Often the problem lies in the surface on which the device is standing. The scales must stand on a hard, flat coating (tiles, laminate, linoleum), a carpet, even with a short pile, or a sloping floor will lead to errors in the tens of percent.
If the scales don't turn on or the display goes out as soon as the numbers appear, replace the batteries. Even if the charge indicator in the application shows the rest, the voltage under load can drop below the critical level. Also try rebooting Bluetooth on the phone: turn off, wait 10 seconds and turn on again.
- 🧹 Rub the glass surface with a dry cloth to remove static electricity.
- 📵 Make sure the scales are not connected to another phone within Bluetooth range.
- 🔄 In case of failure, try to remove the device from the application and add again.
Sometimes it helps to completely reset the scales. To do this, remove the batteries for 1-2 minutes, then insert them back, which will force the controller to restart and reset temporary errors in memory.
💡
If the scales show "ERR" or "Lo," don't try to stand on them right away. First check the floor surface and replace the batteries. A "Lo" error almost always means the discharge of the batteries, even if they are new (possibly defective or long-standing).
💡
Xiaomi's scales are 90% stable depending on the quality of the installation surface and the freshness of the batteries. Software failures are extremely rare.
