Xiaomi’s smart scales are not just a weight measurement device, but a full-fledged health assistant that can analyze body composition, track changes and synchronize data with a mobile application. However, many users face difficulties when connecting a device to a phone for the first time. In this article, we will discuss all the steps from preparing equipment to solving typical errors that can occur in the process.
It is important to understand that the connection algorithm may differ slightly depending on the scale model (Mi Body Composition Scale 2, Xiaomi Smart Scale 2, Mi Smart Scale, etc.) and the smartphone operating system (Android or iOS).We will consider universal steps relevant to most devices, and also pay attention to the nuances that are often missed in standard instructions.
What scales Xiaomi supports phone connection?
Not all Xiaomi smart scales are equipped with a Bluetooth module for synchronization with a smartphone. Below is a list of current devices that can be connected to a mobile application:
- 🔹 Xiaomi Mi Body Composition Scale 2 - flagship model with an analysis of 13 body parameters (muscle mass, bone mass, water level, etc.).
- 🔹 Xiaomi Smart Scale 2 – a simplified version with basic functions (weight, BMI, fat mass).
- 🔹 Mi Smart Scale (first generation) – supports only weight and BMI, but still works with modern versions of apps.
- 🔹 Xiaomi Mi Body Fat Scale – model with an emphasis on fat percentage measurement.
If your model is not listed, check its name on the box or in the documentation.Outdated devices (such as the 2015 Xiaomi Mi Scale) may require special versions of applications or may not support modern communication protocols at all.
What application do you need to connect?
Xiaomi’s weight sync with the phone uses the official Mi Fit app (formerly) or its successor, Zepp Life (since 2022), both available for Android (via Google Play) and iOS (via the App Store), but have a number of key differences:
| Annex | Supported devices | Features | Download link |
|---|---|---|---|
| Mi Fit | Libra until 2021, fitness bracelets Mi Band 1-5 | Outdated interface, limited analytics | Google Play / App Store |
| Zepp Life | Libra 2022 and newer, Mi Band 6/7/8, Watch S1/S2 | Advanced statistics, integration with Apple Health/Google Fit | Google Play / App Store |
⚠️ Note: If your scales are released after 2021 but are not on the Zepp Life list of supported devices, try installing Mi Fit – some models are temporarily duplicated in both apps.
Also note that for proper work requires:
- 📱 Android 6.0+ or iOS 12+.
- 🔄 Bluetooth 4.0+ (smartphone).
- 🌐 Stable Internet connection (for initial setup).
Step-by-step instructions for connecting Xiaomi scales to the phone
Before starting, make sure that:
☑️ Preparation for connection
Now follow the algorithm:
- Set the scales on a flat surface (tile, laminate, wood). Avoid carpets or soft coatings, which distorts the readings of the sensors.
- Turn on the scales by pressing them with your foot or button (if any). The indicator (usually blue or white LED) should light up.
- Open the app (Mi Fit or Zepp Life) and log in (or create an account).
- Go to the "Profile" section" →"Add Device" (in Zepp Life) or "Devices" →"+" (Mi Fit).
- Choose your scale model from the list. If it's not available, click "Other device" and select manually.
- Follow the instructions on the screen: the app will suggest you stand on the scale for calibration. Do it with your bare feet (the socks distort the reading).
- Wait for the sync. The phone screen will show a message about the successful connection.
⚠️ Warning: If the scales are not determined, try turning off and re-enable Bluetooth on your phone. Also check if the scales are connected to another device (for example, a tablet) - in which case you need to first "forget" them in the Bluetooth settings.
💡
If the scales do not respond to pressing, set them on charging for 10-15 minutes. Even if the indicator does not burn, the battery could run to a critical level.
What to do if Xiaomi scales are not connected to the phone?
Connection issues are the most common user complaint, and let’s look at common errors and how to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| Libra is not on the device list | An outdated version of the application or firmware of scales | Update Mi Fit/Zepp Life and reset the scales (hold the 10 seconds button) |
| Synchronization interrupted | Weak Bluetooth signal or interference from other devices | Bring your phone closer to the weights (up to 1 m) and turn off other Bluetooth devices |
| Libras connect but don't transmit data | Incorrect calibration or failure in the application | Remove the scales from the list of devices in the app and add again |
| The application gives an error "The device is not supported" | The weight model is incompatible with the region of the account | Change the region in the settings of the Xiaomi account to "China" (instruction below) |
If none of these things worked, try to lose weight to factory settings.
- Turn off the scales (hold the button for 5-10 seconds).
- Turn them on by holding the button for 15 seconds until the indicator blinks 3 times.
- After resetting, repeat the connection procedure again.

How to set up Xiaomi scales after connecting?
After successful synchronization, it is recommended to configure the following parameters for maximum measurement accuracy:
- 👤 User profile: Specify the exact age, height and gender in the app, and these data affect the calculation of BMI and fat percentage.
- ⏰ Measurement mode: Enable the Automatic Synchronization option (in device settings) to save data at each weighing.
- 📊 Objectives: Set a target weight in the Health section - the app will track progress.
- 🔗 Integration: Connect Zepp Life to Google Fit or Apple Health for centralized data storage.
⚠️ Warning: If you use the Mi Body Composition Scale 2, avoid weighing immediately after exercise or eating - this distorts the readings of muscle and fat mass. Optimal time to measure: in the morning on an empty stomach after going to the toilet.
For advanced users, additional settings are available:
- 🔧 Sensor calibration: In the device menu in the application, you can start recalibration (useful if the scales show knowingly incorrect data).
- 👨👩👧👦 Multiplayer mode: Add profiles for family members – scales will automatically recognize the user by weight.
How to update the firmware of Xiaomi scales?
The firmware of the scales is responsible for the stability of communication and the accuracy of measurements. Updates are rarely issued, but installing them can solve connection problems.
- Open Mi Fit or Zepp Life.
- Go to the connected device section and select your scales.
- Press three points (⋮) top-corner →"Update firmware".
- If the update is available, confirm its installation and wait until it is completed (the scales must be on and be near the phone).
⚠️ Warning: Do not interrupt the update process, this may cause the device to malfunction. If the firmware is stuck, restart the scales (hold the 10 seconds button) and try again.
💡
Updating Xiaomi’s firmware scales takes 2-5 minutes, while do not use other Bluetooth devices and do not leave the application.
Alternative ways of connecting (without an official application)
If you can not connect scales through Mi Fit or Zepp Life, you can use third-party solutions:
- 🔌 Notify & Fitness app (for Android): Supports many Xiaomi devices, including scales. Requires root rights to work properly.
However, please note that alternative methods may:
- 🚫 Deprive you of warranties (if you need to hack firmware).
- 🔒 Violate privacy (third party applications may collect data).
- ⚠️ Lead to unstable work of the scales.
If you still decide to experiment, pre-create a backup copy of the data in the official application.
