Xiaomi Mi smart scales have long become the standard for health care professionals: they not only show weight, but also analyze body composition, synchronize data with fitness apps and even integrate into the Mi Home ecosystem. However, many users face difficulties already at the connection stage β the device does not find the phone, the application gives an error, or the scales simply βdonβt seeβ the user. This article will help you understand all the nuances from choosing the right model of the application to solving rare bugs.
We'll look at the current scale models (Mi Smart Scale 2, Mi Body Composition Scale 2, Xiaomi Smart Scale 3), the features of their connection to Android and iOS, and also give a checklist for troubleshooting. Special attention will be paid to the profile setting, without it, the scales will not be able to correctly calculate body mass index (BMI) and fat percentage. If you have already tried to synchronize the devices and you got "something curve", at the end of the article there is a section with a full resetting of the settings, it will return the scale to the factory state.
We warn you in advance: the connection process takes no more than 5 minutes, but requires a Xiaomi account (Mi Account) without it, data will not be stored in the cloud, and the scales will lose most of the βsmartβ functions. If you do not have a record, register it in advance through the official Mi Fit or Zepp Life app (for new models).
1.What Xiaomi scale models support phone connectivity?
Not all Xiaomi smart scales are equally smart. For example, the budget model of the Mi Smart Scale (first generation) is synchronized only through Bluetooth 4.0 and does not support modern versions of applications. BLE 5.0, which guarantees stable connection and low power consumption. Below is a table with the key characteristics of popular models:
| Model | Support for applications | Protocol of communication | Max. Weight, kg. | Analysis of body composition |
|---|---|---|---|---|
| Mi Smart Scale 1 | Mi Fit (Old Version) | Bluetooth 4.0 | 150 | Weight, BMI |
| Mi Smart Scale 2 | Mi Fit, Zepp Life | BLE 5.0 | 150 | Weight, BMI, % fat/muscle/water |
| Mi Body Composition Scale 2 | Mi Fit, Zepp Life, Apple Health | BLE 5.0 + Wi-Fi (optional) | 150 | 13 parameters (including bone mass, viscosity) |
| Xiaomi Smart Scale 3 | Zepp Life, Mi Fitness | BLE 5.1 | 150 | 17 parameters + Family mode (up to 16 profiles) |
Note that if you have a model older than 2019, you may need to use Mi Fit instead of Zepp Life.+ (You can check the version in the weight settings through the app. Also, some scales (for example, Mi Body Composition Scale 2) require a firmware update on the first connection, we will talk about this in the section on errors.
Tip: if you are not sure about the model, look at the back of the scales - there is a full marking (for example, XMTZC02HM Or check the documents: the name of the box always has the exact name.
Preparation for connection: what to do before synchronization
Before you turn on the scales and open the application, follow a few mandatory steps, and ignoring them is the main cause of errors such as βdevice not foundβ or βfailed to connectβ.
- π± Update the application: Install the latest version of Mi Fit (for the first time) Android/iOS) or Zepp Life (for new models) Links: Android: play.google.com/store/apps/details?id=com.xiaomi.hm.health iOS: apps.apple.com/ru/app/mi-fit/id963774882
- π Charge the scales: If the indicator on the screen flashes red, the charge level is below 10%. Connect to the network for 2-3 hours (use the original USB-Type-C cable for 2020 models).+ year-end).
- πΆ Turn on Bluetooth: The phone must be activated Bluetooth 4.0+ (for iPhone - Bluetooth LE). Also turn off the βEnergy Savingβ mode β it can block the connection.
- π€ Create a profile: In the Mi Fit app, fill in the data: gender, age, height, target weight. Without this, the scales will not be able to calculate the exact composition of the body.
Critical point: Xiaomi scales determine the user by the electrical resistance of the body. If you connect the device for the first time, stand on it with bare feet - socks or slippers will distort the readings. Also avoid wet surfaces (for example, do not put the scale in the bathroom immediately after showering).

3. Step-by-step instructions: how to connect Xiaomi scales to the phone
Now, the process itself. The manual is universal for all models, but there are nuances for Android and iOS, which we will note separately.
Step 1. Turn the scales on.
Click on the touchpad or briefly press the platform β the display with the inscription 0.0 or the Mi logo should light up. If the screen does not respond, check the charge or restart the device (hold the 10 seconds button).
Step 2. Open the application
Start Mi Fit or Zepp Life and go to Profile β Devices β Add the device. Select "Smart Scale" from the list).
Step 3. Start synchronization.
The app will suggest you stand on the scales β do it with your bare feet. On the phone screen, you'll see search animation, and on the scales, the indicator will flash. BLE. If the connection is established, an audible signal will sound, and your weight will be displayed on the scale display.
Step 4. Complete the setup
After successful connection, the application will offer:
- π Link the scale to the Mi Account (required!).
- π Set up automatic synchronization with Google Fit/Apple Health.
- π¨βπ©βπ§βπ¦ Add profiles of other users (up to 16 for Smart Scale 3).
Important: If the scales don't connect the first time, don't panic.
- Exit the application and reopen the βAdd deviceβ section.
- Reboot Bluetooth on your phone (Settings) β Bluetooth β Off./On.).
- Make sure the scales are not connected to another phone (they only work with one device at a time).

If the scales make a mistake E8 When you connect, it means a firmware conflict. Update the software through the app: Device profile β Firmware update.
4. Problem Solving: Scales are not connected to the phone
Even with the right preparation, there can be failures. TOP-5 Errors and ways to fix them based on Xiaomi support data and user feedback.
| Mistake. | Reason. | Decision |
|---|---|---|
| Couldn't find the device. | Bluetooth is off or the scales are discharged | Check the scales and turn on Bluetooth on your phone. Reboot both devices. |
| Mistake. E1/E2 | Unstable connection or interference | Remove other Bluetooth devices (headphones, fitness bracelets) from the scales. Reconnect. |
| Data not stored | No binding to the Mi Account | Go to Profile. β Devices, select scales and tie to your account. |
| Libra shows 0.0. | Sensor or firmware failure | Update your firmware through the app or reset your settings (see Section 6). |
| Wrong body composition | Incorrect user profile | Check the data entered (height, age, gender) in Mi Fit. |
A special case is a mistake E8, It shows up on the Mi Body Composition Scale 2 when you first connect, which means that the scales require a firmware update, but they can't download it automatically:
- Connect the scales to the charger.
- Open Mi Fit and go to Device Profile β Update of the PO.
- If the update does not start, reset the scales to factory settings (hold the 15-second button).
β οΈ Note: If the scales are connected to the phone but the data is not displayed in Google Fit or Apple Health, check your sync settings in Mi Fit β Profile β Applications and services: often the problem is solved by re-authorization.
5. User profile setting: why it matters for accuracy
Many users miss this step, and it is in vain. Xiaomi scales calculate fat percentage, muscle mass and water level based on bioimpedance analysis - a method that depends on individual parameters. If you specify the wrong height or age, the error can be as high as 10-15%!
How to fill out the profile correctly:
- Open Mi Fit and go to Profile β Personal data.
- Indicate the exact height (accurate to cm) and weight (if you know the current one).
- Select gender (the calculation algorithms for men and women are different).
- Fill out the date of birth β this depends on the analysis of metabolic age.
- In the Objectives section, specify the desired weight (this is necessary to plot progress).
For maximum accuracy:
- π©Ί Weigh yourself at the same time (better on an empty stomach in the morning).
- πΏ Do not take measurements after exercise or taking a bath - moisture on the skin distorts the results.
- π Stand on the scales motionlessly, evenly spreading the weight on both legs.
If there are multiple users in the house, add their profiles through Devices. β Libra β User management: Each family member will be automatically recognized by body weight and resistance (libras can remember up to 16 profiles).
π‘
Without a proper profile, the scales will show weight correctly, but the analysis of body composition will be inaccurate, especially critical for athletes and those who monitor body fat percentage.
6.Resetting Xiaomi's weights settings: when it's needed
If the scales are glitchy, not plugged in, or show clearly incorrect data, a complete reset may be required, which will delete all saved profiles and return the device to factory settings.
Method 1. Through a button
1. Turn off the scales from the power (if they are on charge).
2 Hold the touch button for 15 seconds until rSt (reset) appears on the screen.
3. Release the button - the scales will reset.
Method 2. Through the application
1. Open Mi Fit and go to Profile β Devices.
2. Select your scales and press Settings (β) β Remove the device.
3. Confirm the deletion and repeat the connection procedure again.
β οΈ Warning: After reset, all data not synced to the cloud will be lost. If the scales previously worked with another phone, first untie them from the old device via Mi Fit β Devices.
If the reset didn't help, check:
- π Scale Charge: Devices discharged below 5% may not be switched on.
- π± Application Version: Remove Mi Fit and Reinstall.
- π‘ Interference: Bluetooth can conflict with other devices (e.g. wireless headphones).
What if the scales are not turned on after the reset?
7. Additional Features: What Xiaomi Scales Can Do Beyond Weighing
Xiaomiβs modern scales are not just a weight measurement device, but they integrate into the smart home ecosystem and offer features that many people donβt know about:
- π Tracking progress: Automatically plotting weight, fat, and muscle mass with weekly reports.
- πΆ Pregnancy Mode: Special algorithm for expectant mothers (available in Mi Body Composition Scale 2).
- π Integration with Mi Home: Data can be displayed on the display of the Mi Band smart watch or the Mi speakers AI Speaker.
- π Multilingualism: Support for Russian, English, Chinese and other languages (configured in the app).
- π Data export: Ability to unload measurement history in CSV For analysis in Excel or Google Sheets.
One of the most useful features is the Family Mode, which allows you to:
- Create up to 16 individual profiles (for Smart Scale 3).
- Track the progress of each family member on a separate schedule.
- Set personal goals (for example, for a child or an elderly relative).
To activate the mode, go to Mi Fit β Devices β Libra β Manage users and add new members. Every time someone stands on the scale, they automatically recognize them from previous measurements.
