Xiaomi’s smart scales have long been an integral part of the healthy lifestyle ecosystem, but many users have difficulty connecting to the official Zepp Life app (formerly Mi Fit). Despite the seemingly simple process, synchronization can be interrupted due to outdated firmware scales, incompatibility of the app version or banal errors in smartphone settings.
We will not only look at the standard connection procedure for popular models (Xiaomi Smart Scale 2, Mi Body Composition Scale 2, Xiaomi Scale 3), but also solve the typical problems: why scales are not determined by Bluetooth, how to reset the settings to factory, and what to do if the data in the application is displayed incorrectly.
What Xiaomi scales are compatible with Zepp Life?
Not all Xiaomi smart scales support the Zepp Life application. The main criteria for compatibility are the availability of Bluetooth 4.0+ module and support for the Mi Scale Protocol. Below is the current list of models that are guaranteed to sync with the platform:
- 🔹 Xiaomi Mi Smart Scale 2 is the most common model with an analysis of 13 body parameters (including muscle mass and water level).
- 🔹 Xiaomi Mi Body Composition Scale 2 – improved version with increased accuracy and support for multiple profiles.
- 🔹 Xiaomi Smart Scale 3 - budget option with basic functions (weight, BMI, fat mass).
- 🔹 Xiaomi Mi Scale V1 — outdated model, but still supported (requires firmware updates).
Important: Xiaomi scales do not work with third-party applications (for example, Google Fit or Apple Health) directly. Synchronization is possible only through Zepp Life and then transfer data to other services. If your model is not on the list, check it on the official Xiaomi website - it may be related to regional versions (for example, Xiaomi Mi Scale CN).
Preparing for connection: what to do before synchronization
Before you start connecting, make sure that all the prerequisites are met, and ignoring these steps is the main cause of failure:
- Update the firmware of the scales. Outdated software may conflict with the latest versions of Zepp Life. You can check the relevance of the firmware in the Settings → About the scales menu (on some models, through multiple clicks on the scales).
- Install the latest version of Zepp Life. Download the app from Google Play or the App Store. Versions older than 6.0.0 may not support new devices.
- Turn on Bluetooth and geolocation. Libras connect via BLE (Bluetooth Low Energy), and to work correctly requires access to location (this is necessary for finding devices up close).
- Charge the scales. If the charge indicator flashes red or does not burn at all, connect the device to the network for 2-3 hours. Full charge takes up to 4 hours.
Also make sure your smartphone meets the minimum requirements:
| Parameter | Android | iOS |
|---|---|---|
| OS version | Android 6.0 and higher | iOS 12.0 and higher |
| Bluetooth | 4.0+ (BLE) | 4.0+ (BLE) |
| Free seat | 100 MB+ | 150 MB+ |
| Permits | Bluetooth, location, storage | Bluetooth, geolocation, notifications |
Update the firmware to the latest version
Install Zepp Life (version 6.0.0 and higher)
Enable Bluetooth and geolocation on your smartphone
Charge the scales (the indicator should burn green)
Make sure the weight model is compatible with Zepp Life-->
Step-by-step: how to connect scales to Zepp Life
If all the preparatory steps are done, move on to synchronization. The instructions are universal for most models, but there may be minor differences in the interface.
- Open Zepp Life and log in (or create an account if you don’t have one) and use the same account as other Xiaomi devices (like Mi Band) to keep your data synced to the same profile.
- Go to the Profile section (the person icon in the lower right corner) and select Add Device.
- Select the Libra category and find your model in the list. If you don't have a model, select Other Libras, and the app will try to identify it automatically.
- Follow the instructions on the screen: 📱 On your smartphone: confirm the search for devices via Bluetooth. ⚖️ On scales: press the on button (or just step on them – some models are activated automatically). 🔄 Wait for the notification "Device found".
Confirm the connection.
Set up a profile
Once successfully connected, the scales will appear in the list of devices in the Profile → My Devices section. Now, with each weighing, the data will be automatically transmitted to the application. If synchronization has not occurred, go to the "Problem Solving" section.
💡
If the scales aren't determined, try turning off and re-enable Bluetooth on your smartphone, sometimes rebooting both devices helps.
Profile setting and data interpretation
Without a properly configured profile, all Xiaomi weight measurements will be low-level, such as fat percentages based on age, gender and height — if you put the wrong data, the numbers will be overstated or understated.
- Open Zepp Life and go to Profile → Personal Data.
- Specify the exact height (in cm), weight (for calibration), age and gender.
- In the Objectives section, select priority: 🏋️ Weight loss – focus on reducing fat mass. 💪 Muscle mass gain – control of protein and water in the body. ⚖️ Maintaining shape – balance between fat and muscle.
Save the changes and perform the first weighing for calibration.
After weighing, the following parameters will appear in the application (depending on the weight model):
- 📊 Weight - baseline (accuracy) ±50g).
- 📉 BMI (body mass index) – the ratio of weight and height (normal: 18.5–24.9).
- 💧 Water level – percentage of fluid in the body (normal: 45–65%).
- 🦴 Bone mass – skeleton weight (important for bone health assessment).
- 🔥 Basic metabolism (BMR) — Number of calories needed to maintain life.
Important: your body composition (fat, muscle, water) is calculated from bioimpedance analysis — a weak electric current passes through your body. For accuracy, weigh yourself on an empty stomach, without shoes and socks, with an empty bladder.
Problem Solving: Scales are not connected or data is not synchronized
If synchronization fails, check the following points:
⚠️ Warning: If the scales were previously connected to another smartphone, you need to reset them to the factory settings. To do this, press and hold the on button for 10 seconds until the indicator flashes red.
| Problem. | Possible cause | Decision |
|---|---|---|
| Libra is not on Bluetooth. | Outdated firmware of scales or applications | Update Zepp Life and Firmware Scales Through Settings → About Libra |
| Data is not stored in the annex | No internet or account problems | Check your network connection and re-enter your account |
| Libra shows Err error | Overload (maximum 150 kg) or batteries discharged | Check the weight and charge the device |
| App doesn't see scales after reset | Conflict with Bluetooth cache | Clear the Zepp Life cache in the smartphone settings |
If the problem is not solved, try the following:
- Reinstall Zepp Life – sometimes a clean installation helps.
- Check compatibility: Some weight models (such as the Xiaomi Mi Scale CN) only work with Chinese versions of the app.
- Change your account region: Select China in the Zepp Life settings (if your model is for that market).
What if the scales show unrealistic data?
Sync with other services (Google Fit, Apple Health, Strava)
Xiaomi scale data can be transferred to third-party health apps, but only through Zepp Life.
- Open Zepp Life and go to Profile → Settings → Data Synchronization.
- Choose a service for integration: 📱 Google Fit for Android devices. 🍎 Apple Health for iPhone. 🏃 Strava - for athletes.
Log in to the selected service and allow access to data.
Set up synchronization options (e.g., weight only or all metrics).
Important: synchronization is one-way, data is transferred from Zepp Life to third-party apps, but not vice versa, and some parameters (such as bone mass) may not be supported in Google Fit or Apple Health.
⚠️ Note: When you first connect to Apple Health, you may need to confirm your iPhone settings: → Confidentiality → Health → Annexes → Zepp Life.
Operational tips: how to extend the life of Xiaomi weights
Xiaomi smart scales are designed for long-term service, but their accuracy and reliability depend on proper use.
- 🔋 Charging: Use only the original USB-Type-C cable (for battery-powered models) Do not leave the scales on charging for more than 5 hours.
- 🧼 Cleaning: wipe the platform with a damp cloth without abrasives. Avoid getting water on the contacts.
- 📍 Placement: Put the scales on a flat, hard surface (not on a carpet or a tile with gaps).
- ❄️ Temperature: operate at 10–40°C. Storage in cold or heat reduces sensor accuracy.
If the scales have not been used for a long time (more than 3 months), calibrate before the first weighing:
- Put the scales on a flat surface and turn them on.
- Press and hold the 5-second button until CAL appears.
- Wait 10 seconds – the scales will automatically be calibrated.
💡
Weigh yourself at the same time of day (preferably on an empty stomach in the morning) and in the same clothes (or without it).
