Integrating smart devices into Xiaomi’s ecosystem is not just a fashion homage, but a real way to get detailed health analytics. The smart scales from the manufacturer are able to measure not only body weight, but also percentage of fat, water, muscle mass and bone, but in order for this data to become available to the user, you need to perform initial adjustment and synchronization of the gadget with the smartphone.
The connection process can seem confusing due to frequent changes in the interface of mobile applications and the renaming of the service itself. The application was formerly called Mi Fit, then Zepp Life, and now the functionality is gradually moving to Mi Fitness. In this article, we will discuss current pairing methods covering various versions of the software and weight models, such as Mi Body Composition Scale 2.
To get started, you'll need a stable Internet connection and a wireless module on your phone. It's important to understand that scales use Bluetooth Low Energy (BLE) to transfer data, so the distance between the phone and the scales at the time of setting up should be minimal. Ignoring this requirement often leads to a connection timeout and a device search error.
Preparation for the first launch and requirements
Before you get to the software part, you need to make sure that the device is physically ready for operation. Inside the box, there are usually the scales themselves and a brief instruction, but the batteries can be insulated with a plastic cap or absent at all. For the second generation models, four AA finger batteries are required, which you need to install in the compartment on the bottom panel.
⚠️ Warning: Do not leave insulation tape on the contacts of the batteries after removal. The film must be completely removed, otherwise the scales will not turn on and the screen will not light up when weighed.
Once the batteries are installed, the device is ready to go, but don't rush to the platform. The initial calibration of the sensors is automatic when you first turn on, but for the bioimpedance analysis algorithms to work properly, it is important to place the scales on a hard, flat surface. Carpet coatings or soft mats distort the readings of the pressure sensors, making it impossible to accurately calculate the composition of the body.
You should also check your smartphone compatibility. The app requires Android operating systems 5.0 and higher or iOS 9.0 and higher. If your phone is significantly older, sync may not take place due to the lack of support for the necessary Bluetooth profiles.
Installation and configuration of the Mi Fit (Zepp Life) application
The mobile app is the key link in the scale-to-smartphone chain. Currently, the main application for most Xiaomi devices is Zepp Life (formerly Mi Fit), although new models may require Mi Fitness installation. It is recommended to download the current version of the software exclusively from official Google Play stores or the App Store to avoid malicious code.
Once installed, you need to register for your Mi Account or log in through your existing profile, which is a must, as all statistics are stored in the cloud linked to your ID, and without authorization, you can not add scales to the list of devices.
- 📱 Launch the app and log in to your account using your phone number or email.
- 🔍 Go to the Profile tab (usually the person icon in the bottom menu) to manage devices.
- ➕ Click the "Add device" button or the plus in the upper right corner of the screen.
- 📡 Make sure that the smartphone screen has a notification about the request for rights to use Bluetooth and geolocation – they must be allowed.
The interface of the application may vary depending on the version, but the logic remains the same: search is by unique device ID. If the automatic search does not find the scales, you can try to select them manually from the list by finding the category "Libra" or "Scale".
The process of pairing weights with a smartphone
The most important step is the direct connection. When you are in the add-on menu, the app starts scanning the ether, at which point you need to stand on the scale to activate them and start pairing mode, the scale screen should light up, displaying the current weight or flashing readiness indicator.
The list of available devices on the phone screen will appear model name, for example, Mi Body Composition Scale 2, and a unique identifier (MAC-Click on the model name to start the mating procedure. The process can take anywhere from 5 to 30 seconds.
⚠️ Note: If the "H" symbol flashes on the scale screen during pairing, this means that the scale is in standby mode for the user.
Once the connection is successful, the app will request permission to send notifications and access health data, which is necessary to synchronize measurements with other services such as Google Fit or Apple Health, and confirm all permission requests to ensure that the functionality is fully functional.
☑️ Checklist of successful connection
Customize user profile for measurement accuracy
For a bioimpedance test to work correctly, the weights need to know the basic parameters of your body, and the algorithm calculates your body fat percentage, muscle mass, and visceral fat levels based on the inputs you have in your body: height, age, sex, and physical activity levels.
Go to the profile settings in the app and fill in all the fields carefully. Pay special attention to the choice of activity level, because it depends on the calculation of the daily calorie intake. If you are sedentary, but choose "athlete", the calculations will be incorrect.
If the whole family is using scales, you can create profiles for each family member. The app automatically recognizes the user by weight and parameter ratio, assigning data to the corresponding account. For children under 12 years of age or people weighing less than 20 kg, the body composition analysis mode may not work, displaying only weight.
| Parameter | Impact on calculation | Where to change |
|---|---|---|
| Growth | Critical for BMI and body composition | User profile |
| Paul | Affects the norm of adipose tissue | User profile |
| Age. | Adjusts metabolic norms | User profile |
| Figure type | Clarifies calculations for athletes | Weight settings |
Update your profile regularly, especially if you’ve been through periods of intense growth (for teens) or significant weight change.
Why do scales show different percentages of fat?
Update of the firmware of Xiaomi scales
Manufacturers regularly release software updates to correct errors and improve measurement algorithms. If the app offers to update the scales after connecting, it is strongly recommended to do so. The process takes several minutes and requires the phone to be near the scales.
The update is automatically via Bluetooth, and the scale screen can display progress bars or flashing indicators, at which point you should not turn off Bluetooth on your phone or go far from the device.
⚠️ Warning: Interrupting the firmware update process may cause the scales to "brick": Make sure the battery is fully charged and the smartphone is sufficiently charged to complete the procedure.
Once the new version is successfully installed, the scales may reboot. Check the firmware version in the device menu in the app - it must match the latest available version specified in the update description.
💡
If the update is 99% over, try restarting your smartphone and scales (with the batteries out for 10 seconds), then repeat the procedure indoors with a good Wi-Fi signal for the phone itself.
Solving common problems and errors
Even if all instructions are followed, there may be technical difficulties, most often users encounter an error "Device failed to connect" or "Device not found", this may be due to the fact that the scale is already paired with another phone or "hang" the Bluetooth module.
Try resetting the scales. To do this, take out the batteries, wait a minute and insert them back in. Then remove the device from the Bluetooth list in the phone settings (forget the device), and try adding it again through the app.
- 📶 Problem: Libra shows "Lo." Solution: Batteries are dead, need replacement.
- 📶 Problem: Libra shows "Err" Solution: Maximum weight (150 kg) exceeded or platform load uneven.
- 📶 Problem: No data synchronization. Solution: Check the Internet connection and the application's network access rights.
- 📶 Problem: App doesn't see scales Solution: Make sure the scales aren't connected to another phone in the background.
In rare cases, a complete reinstallation of the cache-cleaning app helps, and it’s also worth checking if the power-saving system is blocking Bluetooth for the Mi Fit/Zepp Life app.
💡
90% of connection problems are solved by simply restarting Bluetooth on your smartphone and re-installing batteries in scales.
