Modern health gadgets are becoming an integral part of the smart home ecosystem, and Xiaomi Mi Body Composition Scale 2 is one of the leading places here due to its availability and functionality. The process of initial activation of the device often raises questions among users, especially when trying to link the scales not only with the basic application, but also with more advanced services for detailed analytics. Data synchronization is a key step, without which the gadget turns into a conventional floor scale, displaying only body weight.
To successfully launch, you will need a smartphone that supports Bluetooth 4.0 or later, running Android 5.0+ or iOS 9.0+. It is important to understand that an Internet connection is only necessary when you initially set up and associate an account, while daily weighing can take place offline with subsequent history download. In this article, we will analyze all the nuances of connection, from installing software to solving rare problems with the visibility of the device.
Before starting the procedure, make sure that the device has fresh AAA batteries, as a weak charge can lead to unstable operation of the Bluetooth module. The system requirements of the application are also worth checking in advance to avoid compatibility errors during operation. Readiness to set up ensures that you quickly move to tracking 13 health indicators.
Preparation for the first launch and installation of software
The first step towards digital weight control is choosing the right software. Although the basic Mi Fit app (now Xiaomi Wear) allows you to read weight, for the full operation of the Xiaomi Mi Scale 2, it is recommended to use specialized utilities such as Mi Body Composition Scale or Notify for Mi Band, which can decode all 13 body parameters.
Once you install the app, you need to create an account or log in through your existing Mi Account, which is a must, as the company's cloud server stores your weighing history and schedules changes. When registering, carefully fill in your personal data: height, age and gender are critical for algorithms that calculate the percentage of fat and muscle mass.
Remember to enable Bluetooth in your smartphone settings before you launch the program. Some phone models also require geolocation activation to correctly search. BLE-devices, which is a standard requirement of the Android operating system.
⚠️ Note: If you have previously used scales with another account, be sure to remove the device from the old profile in the application before trying to link to the new one, otherwise there will be a data conflict.
The process of pairing weights with a smartphone
The process of connecting Xiaomi Scale 2 is technically simple, but requires a certain sequence of actions. Unlike the first version of the scales, the “second generation” does not require the inclusion of a separate button – activation occurs automatically when you step on the platform. Open the installed application and go to the add new devices section, usually indicated by the plus icon or the inscription Profile → Add device.
From the list of available gadgets, select the Mi Body Composition Scale 2 model. The app will request permission to access Bluetooth and geolocation — confirm these actions, otherwise the search for the device will not succeed. Stand on the scale with bare feet so that the sensors will fix the contact, and wait for the number “0.0” or flashing Bluetooth icon on the display.
Once the scales are detected, a pairing request will appear on the smartphone screen. Press "Connect" or "Connect"; the process takes no more than 10-15 seconds. Once the balance is successfully coupled, the scales will automatically transmit the current weight data to the app, and you will see your first result.
☑️ Connection checklist
Setting up user profiles
One of the key features of the Xiaomi Mi Smart Scale 2 is support for up to 16 different user profiles, which makes it ideal for the whole family, since the scales automatically recognize a person by their weight and distribute data to their respective accounts. Profile settings take place inside the application: each family member must install the app on his phone and attach the scales to his account.
For proper data separation, it is important that the difference in weight between users is at least 3 kg. If the weights of users are similar, the system can mistakenly record the results of one person to another. In the application settings, you can set a name, avatar and targets for each user profile, which motivates you to monitor progress.
If the scale is used by a guest or a child whose data does not need to be stored in a long-term history, you can use the guest mode, for this purpose, the appropriate option is selected in the application before weighing, and the data will not be tied to any of the permanent profiles.
Interpretation of indicators and work with data
Once connected, you'll have access to advanced analytics that go far beyond just weighing. Xiaomi Scale 2 measures 13 parameters, including fat percentage, muscle mass, visceral fat level, bone density and basic metabolism, all calculated based on bioimpedance analysis, passing a weak, imperceptible current through the body.
To get accurate results, we recommend weighing yourself at the same time of day, preferably on an empty stomach in the morning and after using the toilet. The app visualizes the data in the form of convenient graphs that allow you to track the dynamics of changes. You can see how the ratio of muscle to fat changes when you follow a diet or exercise.
Some indicators, such as body age or protein level, are calculated and can vary depending on the body's hydration, so it's important to take them as a guideline, not as an absolute medical truth, and the regularity of measurements is more important than single records.
Comparison of Xiaomi weight models
Understanding the differences between weights helps you better understand the capabilities of your device, and the second model is a significant step forward from its predecessor, with more metrics and improved design. Below is a table comparing key features of popular models.
| Characteristics | Xiaomi Scale 1 | Xiaomi Scale 2 | Xiaomi Scale S400 |
|---|---|---|---|
| Number of parameters | 1 (Weight) | 13 | 13 |
| Precision of scales | 50g | 50g | 50g |
| Maximum weight | 150 kg | 150 kg | 150 kg |
| Balancing regime | No. | There is. | There is. |
| Platform material | Glass/Aluminum | Glass/Aluminum | Glass/ABS |
As you can see from the table, the second model introduced full body composition analysis, becoming the standard for the budget segment. Newer versions, such as the S400, mainly offer redesigned and NFC support for fast pairing, but the basic measurement functionality remains similar.
Troubleshooting and frequent errors
Even with the right setup, users can face difficulties. One of the most common problems is that the scales are not visible in the list of Bluetooth devices of the phone. This is due to the fact that Xiaomi Scale 2 uses the BLE (Bluetooth Low Energy) protocol and does not appear in the system pairing list of Android or iOS.
If the scales show an error "ERR" If you don't turn on, check the polarity of the batteries and the contact density, sometimes it helps to remove the batteries for 10 seconds and re-install them, and also make sure that the scales are on a completely flat solid surface. soft coating (carpet, carpet) distorts the readings of pressure sensors.
If the app doesn't sync data, check the access rights. Mi Fit or Xiaomi Wear must have background permission and geolocation access. On some smartphones (Xiaomi, Huawei, Samsung), an aggressive energy saving system can kill the sync process, so add the app to the exceptions or whitelist.
⚠️ Warning: Do not try to connect scales through the standard Bluetooth menu of your phone settings - this will lead to pairing error.
Balancing mode and additional functions
Few people know that the Xiaomi Mi Body Composition Scale 2 has a hidden balancing mode that helps develop stability and coordination. To activate this mode, you need to select the appropriate function in the application, stand on the scales on one leg and maintain balance.
This feature is useful not only for athletes but also for older people, as the ability to maintain balance is one of the markers of overall physical health and risk of falls.
In addition, the scales automatically go to sleep to save energy if not used within 10 seconds, awakening occurs instantly on the attack, care for the device is minimal: just wipe the surface with a wet (not wet!) cloth and avoid water entering the body.
