Modern smart scales have long ceased to be just a weighing device, becoming a full-fledged center for monitoring health. Xiaomi Mi Smart Scale 2 (also known as Mi Body Composition Scale 2) is able to measure not only body weight, but also calculate body mass index, determine the percentage of muscle and fat tissue, and analyze the state of visceral fat. For owners of the Xiaomi ecosystem, this device becomes an indispensable assistant in building a healthy lifestyle.
However, in order for the gadget to work correctly and transmit accurate data to the smartphone, it must be properly prepared for the first launch. Many users face difficulties in synchronizing or do not understand how to interpret complex biometrics. In this article, we will discuss the entire process in detail, from unpacking and installing batteries to the intricacies of calibration and using all the functions of the Mi Fit application (now Mi Fitness).
The device is characterized by a minimalistic design, hidden LED-It is important to understand that the accuracy of measurements depends on the surface on which the scale is installed and the correctness of the user's personal data entry. Ignoring basic operating rules can lead to errors in calculations, which is especially critical for those who follow the dynamics of weight.
Primary preparation and activation of the device
The first step after unpacking is to install the batteries. Unlike many other models, the Xiaomi Mi Smart Scale 2 runs on four AAA batteries, which are often included, but it is better to immediately replace them with quality alkaline counterparts. This will ensure the stable operation of the Bluetooth module for a long time.
After the batteries are installed, the scales must be activated. There is a small circular switch on the bottom of the device. It must be moved to the ON position. If the scales do not respond to touch after switching on, check the polarity of the installed batteries or try to replace them with new ones, since during prolonged storage the charge may decrease.
⚠️ Warning: Do not place scales on soft carpets or villous surfaces. To work properly strain gauges need a hard, smooth and non-conductive surface, such as tile floor or laminate flooring.
Once turned on, the hidden display can flash segments, confirming the system is working, now the device is ready to weigh, but for full analytics requires pairing with a smartphone. Without this step, you will see only the weight, but you will not get a detailed analysis of body composition.
Installation of software and pairing with a smartphone
To manage weights and save the history of measurements, the Mi Fitness app (formerly Mi Fit) is available for Android and iOS operating systems, and download the program should only be from official Google Play or App Stores to avoid malware and ensure stability of work.
The process of setting up an account and adding a device is as follows:
- 📱 Launch the app and log in via your Mi Account, Google or Apple account ID.
- 🔍 Go to the Profile tab and select “Add device».
- ⚖️ In the list of available gadgets, find Mi Smart Scale 2 and click “Connect».
- 👣 Stand on the scales with one foot so that they come out of sleep mode and start searching for a smartphone.
It is important to give the application all the permissions requested, including access to geolocation and Bluetooth. On Android devices without geolocation enabled, the search for Bluetooth devices can be blocked by the system. Once successfully paired, the scales will automatically transmit weight data to the user profile.
If the scales aren't an app, try restarting Bluetooth on your phone or restarting the app itself. Also make sure the smartphone doesn't run other weights apps that can intercept the connection.
Calibration and accuracy of measurements
One of the key features of the Xiaomi Mi Smart Scale 2 is its automatic calibration, and each time it is turned on, it performs self-diagnosis and adjusts the zero point, but it is recommended to perform manual calibration periodically to achieve maximum accuracy, especially if you have moved the scale to a new place.
Calibration doesn't require complicated manipulations, it's enough to just turn on the scale, wait for the number "0.00" or "0.0" to appear on the display, and then stand on the platform. If you stand on the scale at the time of switching on, while the self-tuning process is underway, the readings may be incorrect.
There is also a "targeting" method to improve accuracy when weighing loads (for example, if you use scales to weigh items even though they are designed for humans).
- Turn the scales on and wait for zero to stabilize.
- Put on the platform an object of known mass.
- Remove the item and wait for zero again before the next use.
Why do scales show different weights?
Remember, biometagrams (measurement of percentage of fat and muscle) require skin to contact electrodes located at the corners of the platform, and will be more accurate if the feet are clean and dry, but not overdried.
Interpretation of health indicators
After weighing, the app generates a detailed report containing up to 13 different indicators, and understanding these data is critical to adjusting exercise and nutrition, with BMI (Body Mass Index), which is calculated using the weight/height formula 2.
But BMI doesn't take muscle-to-fat ratio into account. A person with a lot of muscle mass can have a high BMI, formally falling into the category of "obesity," even though he's in fact in great shape. That's why Xiaomi Mi Smart Scale 2 uses bioimpedance analysis, passing a safe electrical pulse through the body.
The table below shows the main indicators and their significance:
| Indicator. | Description | Norm (exemplary) |
|---|---|---|
| Percentage of fat | Percentage of fatty tissue in the body | 10-20% (M), 20-30% (F) |
| Muscle mass | Total weight of skeletal muscle | Depends on weight and height |
| visceral fat | Fat around internal organs | 1-9 (healthy level) |
| Bone mass | Mineral density of bones | 2.5 - 4.0 kg |
And you have to pay special attention to visceral fat, which is more dangerous than subcutaneous fat, because it affects the heart and liver, and scales help you track the dynamics of this indicator, which is difficult to assess visually.
💡
For the most accurate fat percentage, weigh barefoot, and having socks or thick skin on your heels can impair signal conduction and distort body composition analysis.
Working modes and user profiles
Xiaomi Mi Smart Scale 2 supports up to 16 different user profiles, making it ideal for a large family, and automatically recognizes the user based on weight data and the history of previous measurements, sending the results to the appropriate account in the app.
To adjust family use, you need to:
- 👨👩👧👦 Create profiles for all family members in the “My profile” section» → «Family members».
- 📝 Include accurate data: height, age, gender for each profile.
- 🔄 When you first weigh a new person, the scales can identify him as a "Guest." After weighing in the app, you need to manually tie this measurement to the profile you created.
There is also a mode of weighing babies, which requires you to select the appropriate option in the application: an adult takes the child in his arms, stands on the scale, and the system automatically subtracts the weight of the adult (if it was recorded earlier) or allows you to enter the adult weight manually for calculation.
⚠️ Attention: Infant weighing regime requires extreme caution. Never leave a child on a scale unattended, even for a second.
Automatic recognition works well, but if there are people in the family who are close to the weight (less than 1-2 kg), the system can go wrong, in which case the data can be easily transferred to the desired profile after the fact through the application interface.
Troubleshooting and maintenance
In the process of operation, users may face a number of typical problems, most often they are associated with battery discharge or loss of communication. If the display lights up the battery indicator, replace all four cells at once.
If the scales are no longer synchronized with the smartphone:
- Remove the device from the Bluetooth list in your phone settings.
- In the Mi Fitness app, remove the scales from the list of devices.
- Remove the batteries from the scale for 10 seconds, then insert back.
- Perform re-conjugation through the application.
☑️ Diagnosing Weight Problems
To clean the platform, use soft cloth slightly moistened with water. Do not use aggressive chemicals, abrasives or large amounts of water that can leak into the housing and damage electronics.
💡
Most of the problems with the Xiaomi scales are solved by completely replacing the battery set and re-pairing by removing the device from the phone’s Bluetooth menu.
