The modern approach to health control requires not just weighing, but deep analysis of body composition, and this is what Xiaomi Scale 2 was created for. This gadget is able to determine not only total weight, but also the percentage of fat, muscle mass, bone tissue and water in the body. Connecting to a smartphone turns a conventional weighing into a full-fledged diagnosis, the results of which are stored in history and help track the dynamics of changes.
Many users have difficulty in initial synchronization or misinterpreting data due to a lack of basic knowledge about bioimpedance analysis. In this article, we will discuss the setup process, the nuances of connecting to the Mi Home or Mi Fitness app, and how to achieve maximum measurement accuracy. Proper use of the device is the key to correct statistics of your health.
It's worth noting that the accuracy of readings is directly dependent on the user's operating conditions and training, for example, weighing on a soft carpet or immediately after a heavy meal will distort the results. We'll look at all the technical aspects of how sensors and algorithms work so that you can fully realize the potential of your device.
Technical features and working principle
At the heart of Xiaomi Mijia Smart Scale 2, the bioimpedance analysis (BIA) technique allows a weak, completely safe electrical current through the body that is not felt by the person. Different tissues conduct current at different speeds: muscles containing a lot of water are good conductors, and adipose tissue has high resistance.
Four high-precision sensor cells placed at the corners of the platform capture these resistance changes. Based on the data you receive and the personal parameters you enter (height, age, gender), the scale processor calculates a detailed map of the body. It is important to understand that calculation algorithms require accurate input data to work correctly.
The platform is made of tempered glass with a matte coating, which prevents slipping and scratching. OLED-A display that is activated only at the time of weighing to save energy. AAA-batteries that last for several months of active use.
- 🔋 High accuracy: Sensors respond to weight changes from 50 grams, allowing even minimal fluctuations to be tracked.
- 📡 Dual-mode connection: Bluetooth 5.0 support for synchronization with a smartphone and standard weights mode without a phone.
- 👥 Multiplayer: The device automatically recognizes up to 16 different users and distributes data to profiles.
⚠️ Note: The device cannot be used by people with pacemakers or other implanted medical electronic devices due to the use of bioimpedance analysis.
For electronics to work properly, it is important to maintain a temperature regime: the optimum ambient temperature is from 10 to 40 degrees Celsius; sudden temperature changes can lead to condensation of moisture inside the housing, which will adversely affect the electronic components.
Primary setting and connection to the smartphone
Starting with the gadget requires installing special software. The main application for the Xiaomi ecosystem is Mi Home (for global versions) or Mi Fitness (formerly Zepp Life), the choice of application depends on the regional version of the device and personal preferences, but the functionality in both cases remains similar.
After installing the application, you need to create an account or log in to an existing one. Next, you should add a new device by selecting the Libra category and finding Mijia Smart Scale 2 in the list. The search process can take some time, so keep your smartphone in close proximity to the scales.
The critical step is to enter personal data, without height, age and sex, scales cannot calculate the percentage of fat and muscle mass, showing only total weight. Make sure that the profile contains current data, because this depends on the correctness of the calculations of body composition.
Connection is automatically activated when you first weigh in after activating Bluetooth on your phone. If sync is not happening, check the application permissions: access to geolocation and Bluetooth must be enabled forcibly in the settings of the Android or iOS operating system.
Step-by-step instructions: how to use weights
Operating the device is as simple as possible and does not require complex manipulations. To obtain stable results, it is recommended to develop the habit of weighing yourself at the same time of day, preferably on an empty stomach in the morning, after going to the toilet and before drinking water.
Stand on the platform with your bare feet, spreading the weight evenly. The feet should be in full contact with metal contacts (if any) or just be on the surface of the sensors. Do not move or talk during the measurement, as this can interfere with the reading process.
☑️ Checklist of proper weighing
After fixing the weight on the display will appear the corresponding symbol, and after a few seconds the data will be transmitted to the smartphone. If the phone is far away at this point, the weight will remain in the internal memory of the device (up to the last 10 weighings) and synchronize with the next connection.
To switch between users, no additional actions are required. The system analyzes weight and history of changes, automatically suggesting a profile that best matches the current parameters. If the scales cannot identify the user, the data is marked as "Guests".
| Parameter | Description | Unit of measurement |
|---|---|---|
| Body weight | Total body mass | kg/pound |
| Percentage of fat | Percentage of fatty tissue in the body | % |
| Muscle mass | Mass of skeletal muscle | kilogram |
| Bone mass | Mineral density of bones | kilogram |
| visceral fat | Fat around internal organs | Levels (1-20) |
Interpretation of indicators and analysis of data
When you get these numbers, you're left wondering what they mean for your health: Body Fat Percentage is a key metric that's more important than your total weight. Norms vary by gender and age: 10-20% is normal for men, 18-28% is normal for women.
Muscle mass is the number of skeletal muscles, and the growth of this parameter indicates the effectiveness of training, even if the total weight is standing still or growing, because muscle is denser than fat, and when you gain muscle mass, your body volume can decrease.
What is visceral fat?
The balance of water in the body is also an important indicator: Dehydration can mask real progress in fat burning, as water loss leads to a sharp weight loss that returns quickly.
When analyzing data in the app, pay attention to trends, not one-off jumps. A person’s weight can fluctuate by 1-2 kg during the day due to food intake, fluids and salt. Monthly averages give a much more objective picture of the changes occurring.
Calibration and accuracy of measurements
While the Xiaomi Scale 2 does not require regular manual calibration by the user, there are a number of factors that affect accuracy.The first and most important condition is to set the scales on a hard, flat surface. Soft coatings, such as carpets or linoleum with pile, absorb some of the pressure, underestimating the real performance.
If you have moved the scales to a new place, it is recommended to do one “idle” weighing (act as if you are weighing, but do not stand up completely, or simply press your foot to activate) so that the device is zeroed and calibrated under a new surface.
💡
Rub the surface of the scales with a dry soft cloth before each use. Dust, villi or water drops under the feet can disrupt contact with sensors and distort the bioimpedance analysis data.
Batteries also play a role. When batteries are discharged, the voltage drops, which can lead to unstable electronics and erroneous readings. If the scales start to behave strangely or stop connecting to Bluetooth, first replace all four batteries with new, preferably one manufacturer.
In rare cases, it may be necessary to reset the device. 10-15 And then you put them back in, and that'll reboot the internal controller and fix the software failures.
Error Resolving and Troubleshooting
One of the common problems is the error message "LO" or "Err" on the display, which usually indicates overload (exceeding the maximum weight of 150 kg) or, conversely, too low weight (less than 5 kg), which the device can not measure correctly, and an error can occur if the user is standing on the scales unstable.
Bluetooth connectivity issues are often solved by restarting the Bluetooth service on your phone or removing the device from the list of paired system settings followed by a re-search in the app.
⚠️ Warning: Do not try to disassemble the scale body yourself. Breaching the tightness will lead to moisture and dust on the sensors, which will permanently disable the device and deprive the warranty.
If the scales show different values when weighing again with a difference of more than 300 grams, check the legs of the scales. There should be no debris underneath, and the legs should fit tightly to the floor. Any swaying of the platform is unacceptable for accurate measurements.
💡
The stability of the readings depends on the surface: use scales only on a hard, flat floor (tiles, laminate, concrete).
