Modern technology has turned a conventional weighing process into a full-fledged collection of health data. Xiaomi’s smart scales have become a popular tool for fitness watchers, and they can analyze not only body weight, but also percentages of fat, water, muscle mass, and even bone, but to access these features, you need to perform the proper initial setup of the equipment.
The connection process can seem confusing to a beginner due to the peculiarities of the Bluetooth protocol and the logic of mobile applications. Often users are faced with the fact that the device is not visible in the list of available gadgets or data is not transmitted to the server. It is critical to install the Mi Fitness app (formerly Zepp Life) before starting any manipulation of weights. In this article, we will detail every step, from unpacking to the first successful measurement.
Preparation of the device for the first launch
Before you try to sync your scales with your smartphone, you need to make sure they're physically ready to work. The box with the device usually contains the scales themselves, a brief instruction and, in some models, batteries. If you don't have the batteries, you'll need four standard AAA batteries. The quality of the power supplies directly affects the stability of the Bluetooth module.
Put the batteries in a special compartment on the bottom of the case. Pay attention to the polarity: the plus and minus contacts must strictly follow the markings inside the compartment. Once the batteries are installed, the device automatically turns on when you lightly press the platform, and the display will light up digital indicators. This is a signal that the hardware is healthy and ready to pair.
⚠️ Warning: Do not leave a protective film on the display screen after unpacking. It can distort readings or prevent sensor activation if it is glued too tightly.
It is also important to choose the right place to install: the glass platform should lie on a flat, hard surface; carpets, fuzzy mats or soft flooring are unacceptable, because they disrupt the work of strain gauges; the scales should stand still to exclude calibration errors.
💡
Put the scales on the tile or laminate. If the floor is heated, make sure that when weighed, it does not create strong heat fluxes that can affect the accuracy of the sensors.
Installation and configuration of the Mi Fitness application
Xiaomi uses an ecosystem of apps to manage weights, the main one being Mi Fitness (older versions of Zepp Life), which can be downloaded from official Google Play or App Stores. Once installed, start the program and log into your Mi Account. If you don't have one, you'll need to quickly register with your phone number or email.
Inside the app, go to the profile section and add a new device. Click on the plus in the corner of the screen or select Add Device from the menu. In the list of available gadgets, find your weight model (for example, Mi Body Composition Scale 2). The app will request permission to use Bluetooth and geolocation - be sure to confirm these requests, otherwise the search for devices will not start.
The search process can take anywhere from 5 to 30 seconds. If the scales are nearby and on, they will appear in the list. Click on the model name to start pairing. A flashing indicator may appear on the scale screen to confirm the mode(s). After successful connection, a welcome window will appear on the smartphone screen with a suggestion to customize the user profile.
Setting up a user profile for accurate calculations
The accuracy of the bioimpedance analysis that the scales perform depends on the personal data you enter. BI-The analysis uses height, age and gender to calculate the percentage of fat and muscle tissue. If these parameters are entered incorrectly, the final numbers on the smartphone screen will be far from reality, even if the scales show body weight correctly.
In your application profile, create an account for each family member who plans to use the device.
- 👤 Gender (male/female) – affects the formulas of metabolism calculation.
- 📏 Growth is a critical parameter for body mass index (BMI).
- 🎂 Date of birth - age affects the speed of metabolic processes.
- 🏃♂️ Activity level – helps to adjust calorie recommendations.
After filling out the questionnaire, the system will ask you to choose which users will be measured. Xiaomi scales can automatically recognize up to 16 different users. They compare the current weight with previous measurements and assign the result to the appropriate profile. For children under 12 years of age, the body composition analysis mode is usually turned off, the scales show only the mass so as not to mislead parents.
☑️ Profile verification
First weighing process and calibration
The first time you're on and standing on the platform is when you first calibrate, stand on the scale barefoot or with thin socks, and it's important that your feet fit tightly to the contact areas (if any) or just spread the weight evenly across the glass, and wait until the numbers on the display stop flashing and get fixed.
At this point, the scales transmit data to the smartphone via Bluetooth. On the phone screen, you will see a detailed report. If this is the first weighing, the application may ask to confirm that the data belongs to you. Confirm the action to save the history. Subsequent weighings will take place faster, since the scales already “know” your weight range.
| Parameter | Description | Accuracy of measurement |
|---|---|---|
| Body weight | Total body mass | ±50 g |
| EMIT | Body mass index | ±0.1 |
| Percentage of fat | Percentage of adipose tissue | ±1.0% |
| Muscle mass | Weight of skeletal muscles | ± 0.5 kg |
To get the most accurate results, it is recommended to weigh yourself at the same time of day, preferably on an empty stomach in the morning, after using the toilet and before drinking water. Clothing also introduces an error, so it is better to perform the procedure without clothes. Stability of conditions is the key to tracking the dynamics of changes.
Integration with other services and synchronization
Xiaomi's ecosystem allows you to go beyond just one app, and your weight and body composition can be automatically transferred to Google Fit, Apple Health, or Runkeeper, which is convenient if you use different trackers for exercise and nutrition, and you want to see a single picture of health in one place.
To set up sync, go to the profile settings in the Mi Fitness app. Find the Add Accounts or Third Party Apps section. Choose the service you want and log in to. After that, all new measurements will be duplicated in the selected system. Note that reverse sync (from Google Fit to Mi Fitness) doesn't always work correctly, so the main source of data is better to leave the native application.
⚠️ Note: When syncing with Apple Health, make sure you give permission to record weight data.Without this right, the Xiaomi app will not be able to transfer information to the system.
If you use a smartwatch from the same manufacturer, the workout data from the watch can be combined with the weight data to form a more complete report of calorie expenditure per day, creating a powerful tool for controlling energy balance.
What to do if the data is not synchronized?
Solution: Scales are not connected or lie
Despite the simplicity, users often face technical challenges, the most common being that the scales are not visible in the app. Make sure your phone is Bluetooth and GPS enabled. In Android, Bluetooth Low Energy (BLE) often requires geolocation access, even if you don't need navigation.
Another common problem is that the readings are not consistent with the medical scales, and remember that home devices are biased, and bioimpedance analysis is sensitive to hydration, and if you've had a liter of water or a good meal, the fat percentage can temporarily jump, and compare the weekly performance, not the individual measurements.
If the scales show "Err" or "Lo":
- 🔋 «Lo means battery discharge – replace the entire set with a new one.
- ⚖️ «Err" may mean overloading (exceeding 150 kg) or mounting on an uneven surface.
- 📡 Connection issues are often solved by restarting Bluetooth on your phone.
💡
Most connectivity problems are solved by completely restarting the smartphone’s Bluetooth module or reinstalling the app.
