Xiaomi’s smart scales are not just a weight measurement device, but a full-fledged health assistant. They analyze body composition, monitor changes, and integrate with mobile applications for integrated monitoring. However, many users face difficulties in first syncing a device with a smartphone. In this article, we will examine all the stages of connection, from choosing the right application to eliminating typical errors.
Xiaomi's weights (Mi Body Composition Scale, Mi Smart Scale 2, Xiaomi Smart Scale) feature using Bioelectrical Impedance Analysis (BIA) technology to measure 13+ body parameters. But without proper synchronization with your smartphone, you'll only get the basic data - weight and IMD. So the right communication setup between devices is critical to unlocking the full potential of the gadget.
What scales Xiaomi supports synchronization with a smartphone
Not all Xiaomi smart scales are equally compatible with mobile devices, here is the current list of supported devices (as of 2026):
- 🔹 Xiaomi Mi Body Composition Scale 2 is a flagship model with measurements of muscle mass, bone tissue and metabolic age.
- 🔹 Xiaomi Smart Scale 2 – budget version with basic metrics (weight, IMD, Fat mass. Supports Bluetooth 4.2.
- 🔹 Xiaomi Mi Scale (first generation) – outdated model, but still compatible with the Mi Fit app.
- 🔹 Xiaomi Body Fat Scale – a specialized version for athletes with advanced analytics.
Important: models without Smart or Body Composition labels (such as Xiaomi mechanical scales) do not support synchronization. Also check that your smartphone runs Android 6.0+ or iOS 10.0+ - older versions of the OS may not support current communication protocols.
What application is needed for synchronization
Until 2021, all Xiaomi scales were connected through the Mi Fit application. However, after rebranding the Mi ecosystem in Xiaomi and separating services, some devices were transferred to the management of Zepp Life (formerly Amazfit).
| Annex | Supported weight models | Features |
|---|---|---|
| Zepp Life | Mi Body Composition Scale 2, Smart Scale 2 (new installments) | Advanced analytics, integration with Apple Health and Google Fit, cloud storage |
| Mi Fit | Mi Scale (1st generation), Smart Scale 2 (old batches) | Simple interface, basic statistics, support for Chinese firmware |
| Xiaomi Wear | Experimental support for new models (in China only) | Unstable work, limited functionality |
How do you determine which application you need?
- Look at the scale box, and it shows the recommended program.
- Check the model in Bluetooth settings: if the device name has XMSH, use Zepp Life; if XMTZC is Mi Fit.
- For scales purchased after 2022, prioritize Zepp Life.
⚠️ Warning: Don't install both apps at the same time! This can cause synchronization conflicts and data duplication. If you've previously used Mi Fit, export your data history manually before switching to Zepp Life.
Step-by-step instructions for synchronizing the scales with the phone
The connection process takes no more than 5 minutes, if you follow a clear algorithm, we will analyze the universal instructions that are relevant for both applications (Zepp Life and Mi Fit).
1. Preparation of the smartphone
- 📱 Turn on Bluetooth on your phone (Visible for all devices mode is not required).
- 📲 Make sure that the smartphone is allowed access to geodata for the application (required for the correct operation of the algorithms).
- 🔋 The battery charge of the scales should be at least 20% (check the indicator on the screen when turning on).
2. Installation and configuration of the application
- Download Zepp Life (App Store/Google Play) or Mi Fit (App Store/Google Play).
- Sign up or sign in via your Xiaomi/Zepp account (you can use Google or Apple ID).
- In the main menu of the application, click Profile → Add device → Libra.
3. Liquidation of scales
Stand on the scales with bare feet (for accurate measurement of impedance)
Wait for the Bluetooth icon to appear on the scale screen
Confirm the connection in the application (click "Sync")
Do not leave the scales until the process is completed (10-15 seconds)
-->
If the scales are not detectable:
- Reboot Bluetooth on your phone (Settings → Bluetooth → Off/On).
- Press the reset button on the scales (usually located under the battery compartment cover) and try again.
- Make sure the scales are no more than 1 meter away from the phone.
💡
If you have an iPhone, open Settings → Privacy → Geolocation Services before connecting and enable access for the Zepp Life/Mi Fit app in “When in Use” mode.
4. User profile setting
After successful connection, the application will request your personal data for accurate calculations:
- 👤 Gender (male/female)
- 📏 Growth (indicate in centimeters)
- 🎂 Date of birth (to calculate metabolic age)
- 🏃♂️ Activity level (sedentary/moderate/active)
Critical error: if you specify the wrong height, the fat mass and muscle composition will be distorted by 15-20%. If necessary, the data can be changed later in the Profile → Edit section.
Common synchronization errors and their solution
Even with the right connection, users often face problems.-5 errors and ways of eliminating them:
| Mistake. | Reason. | Decision |
|---|---|---|
| Libras not included | Batteries discharged (4×AAA) | Replace the batteries with new ones (we recommend Duracell or Energizer). |
| App doesn't find scales | Conflict of Bluetooth connections | Turn off other Bluetooth devices (earphones, fitness bracelets). Reboot your phone. |
| Data not stored | There is no access to the Internet | Connect to Wi-Fi or mobile. In Zepp Life, check your cloud sync settings. |
| Fat/muscle indicators are incorrect | Incorrect user profile | Check the height, weight and age specified in the app. Repeat the measurement with your bare feet. |
| Libras are switched off during measurement | Weak Bluetooth signal | Make sure there are no obstacles (metal, walls) between the phone and the scales. |
If none of these methods helped, perform a complete weight reset:
- Remove the batteries for 30 seconds.
- Hold the switch on for 10 seconds (until the screen blinks).
- Install the batteries back and repeat the connection procedure.
⚠️ Note: After resetting, all data stored in the balance memory (up to the last 16 measurements) will be deleted. To avoid loss of history, pre-export data in the application: Profile → Export of data → CSV.
How to sync data with other services (Google Fit, Apple Health)
One of the key benefits of Xiaomi’s smart scales is the ability to integrate with popular health platforms, which allows you to collect all the metrics in one place and use them in third-party applications (such as MyFitnessPal or Samsung Health).
Sync with Google Fit (Android)
- Open Zepp Life or Mi Fit.
- Go to Profile → Settings → Data Synchronization.
- Select Google Fit and log in through your Google account.
- Allow access to data on body weight and composition.
Update is automatically updated every 4 hours. For forced synchronization, click Update in the Google Fit section.
Sync with Apple Health (iPhone)
- 🍎 In Zepp Life, go to Profile → Apple Health.
- 🔗 Turn on switches for parameters: Weight, Fat Percentage, Muscle Mass.
- 🔄 Data will be available in the Health app in the Overview section → Body. → Measurements.
What if the data is not synced with Apple Health?
Important: Mi Fit doesn’t support syncing with Apple Health on iOS 15+. For iPhone owners, make sure to use Zepp Life.
Tips for Accurate Measurement and Weight Care
To get the most reliable data, follow these recommendations:
- ⏰ Measure your weight at the same time (better on an empty stomach in the morning after using the toilet).
- 🚿 Do not take measurements after a hot shower or intense exercise – this distorts the fluids in the body.
- 👣 Stand on the scales with bare feet, evenly spreading the weight on both legs.
- 📵 Do not put the scales on a carpet or soft coating - only on a solid flat surface.
To extend the life of the device:
- 🔋 Use alkaline batteries (not rechargeable!) Change them once in a while. 6-8 months.
- 🧹 Wash the contacts on the scales with a dry cloth once a month (wet cleaning is prohibited!).
- 🌡️ Keep the scales at a temperature of 10°C to 40°C – Extreme conditions can damage sensors.
💡
For the most accurate results, take 3 measurements in a row at 1 minute intervals and average the measurements. The range between measurements should not exceed 0.3 kg - if more, check the contacts on the scales or replace the batteries.
