Why Xiaomi Smart Scales Require a Phone Connection β and What It Gives Users
Xiaomi's smart scales are not just a weight measurement device; they analyze body composition, track changes, and integrate with the Mi Home ecosystem or health apps. But without synchronization with your smartphone, most of the features will not be available. The data will not be stored in history, you will not be able to track progress in training, or share the results with your doctor.
Connecting the scales to the phone opens access to:
- π Detailed statistics - not only weight, but also the percentage of fat, muscle mass, water in the body, bone mass and even metabolic age.
- π± Automatic sync with Google Fit, Apple Health or Mi Fitness for comprehensive health analysis.
- π¨βπ©βπ§βπ¦ Multiplayer mode β scales recognize up to 16 users by weight and store data for each in a separate profile.
- π Visualization of progress β schedules of changes for a day, week, month or year with the possibility of exporting to the region PDF.
However, the connection process can cause complications, from the lack of response of weights to Bluetooth to errors in the application. In this article, we will analyze all the synchronization steps for the Mi Body Composition Scale 2, Xiaomi Smart Scale 2 and others, and solve typical problems.
What Xiaomi scale models support phone connection
Not all Xiaomi scales are equipped with Bluetooth data transfer module. Here is the current list of supported models (2026):
| Model | Bluetooth support | Compatible annexes | Max. Weight, kg. |
|---|---|---|---|
| Mi Body Composition Scale 2 | β Bluetooth 5.0 | Mi Fit, Zepp Life | 150 |
| Xiaomi Smart Scale 2 | β Bluetooth 4.2 | Mi Fit | 150 |
| Mi Smart Scale (1st generation) | β Bluetooth 4.0 | Mi Fit (outdated firmware) | 150 |
| Xiaomi Body Fat Scale | β Bluetooth 5.0 | Zepp Life, Mi Fitness | 180 |
If your model is not listed in the table, check for the Bluetooth logo on the case or in the instructions. Libras without a wireless module (for example, mechanical Xiaomi Basic Scale) can not be synchronized - they are only designed for local weighing.
Preparing for connection: what to do before synchronization
Before you connect the scale to your phone, follow a few mandatory steps, which will eliminate errors such as "device not found" or "failed synchronization".
Make sure the scales are charged (the indicator burns when pressed)
Download the official application (Mi Fit or Zepp Life)
Enable Bluetooth and geolocation on your phone
Put the scales on a flat, hard surface (not on a carpet!)
Delete old data about weights in the application (if you have previously connected)-->
Critical: Xiaomi scales are powered by AAA batteries (4 pieces). If the indicator does not light up when you press the platform, replace the batteries. Use only high-quality alkaline batteries - cheap analogues can cause data transmission failures.
β οΈ Note: If you have previously used a scale with another phone, remove it from the device list in Settings β Bluetooth on an old smartphone, otherwise the new sync may end in error due to a connection conflict.
Also check the compatibility of your phone:
- π± Android: version 6.0 and higher, Bluetooth 4.0 support+.
- π iOS: iPhone 5s and newer, iOS 10.0 or higher.

If you have a Xiaomi or Redmi smartphone, turn on the βDual Bluetooth Connectionβ mode in Settings β Connections β Bluetooth. This will speed up the search for weights.
Step-by-step: how to connect Xiaomi scales to the phone via Mi Fit
Mi Fit is the official tool for working with Xiaomi scales. Follow the instructions to avoid errors:
- Install Mi Fit from Google Play or App Store. Sign up or sign in via your Xiaomi/Google/Apple account.
- Turn on Bluetooth and geolocation on your phone. Without geolocation, the app won't be able to identify the region and can block the connection.
- Open Mi Fit, go to Profile β Add device β Libra.
- Select your scale model from the list. If you don't have one, click on Another device and select Mi Smart Scale 2 (Universal Profile).
- Stand on the scale with your bare feet. A flashing Bluetooth indicator will appear on the scale screen, which is the connection signal.
- Wait for the vibration of the scales and the sound signal. The notification "Connected successfully" will appear in the application.
If the scales don't respond, try:
- π Reboot Bluetooth on your phone (turn off/on).
- π± Remove the Mi Fit app cache in your phone settings.
- π Replace batteries in weights even if the indicator is on.
β οΈ Note: If you use an iPhone, open Settings before connecting β Confidentiality β Geolocation services and set Mi Fit to Always. Without that, synchronization will be interrupted.
Alternative ways to connect: Zepp Life and third-party apps
If Mi Fit is not suitable (for example, due to regional restrictions), use Zepp Life, an app from the same manufacturer, but with advanced health analysis features.
Instructions for Zepp Life:
- Download Zepp Life (Android/iOS)
- Sign up or sign in through your Xiaomi account.
- Go to the Devices. β Add β Libra.
- Select a model and follow the on-screen prompts (similar to Mi Fit).
Zepp Life offers more detailed reports, including:
- π Weekly reports with nutritional recommendations.
- ποΈ Integration with training (stepmers, treadmills).
- π©Ί Tips for improving body composition based on AI analysis.
What data does Zepp Life transfer?
Third-party apps like Health Sync or Google Fit can import data from Mi Fit/Zepp Life, but don't support direct weight connection. Use it only to export statistics.
Solution: Xiaomi scales do not connect to the phone
If the synchronization ends in an error, check the following points:
| Problem. | Possible cause | Decision |
|---|---|---|
| Libras not included | Batteries discharged or contacts oxidized | Replace batteries, wipe contacts with alcohol |
| App doesn't find scales | Bluetooth is off or scales are not in pairing mode | Turn on Bluetooth, stand on the scale to activate |
| The "failed to connect" error | Conflict with another device in the memory of the scale | Reset the scales to factory settings (hold the 10 sec button) |
| Data not stored | No internet or account failure | Check the connection to the network, re-enter the account |
If the scales are connected but show incorrect data (for example, an inflated percentage of fat), calibrate:
- Stand on the scale and wait for measurements.
- In the app, go to Device Profile β Settings β Calibration.
- Follow the instructions on the screen (you may need to enter the weight manually).
β οΈ Attention: To measure body composition accurately, weigh yourself at the same time (preferably on an empty stomach in the morning), with bare feet and on a hard surface.
How to set up multiple profiles on a single scale
Xiaomi scales support up to 16 users with automatic recognition.To add a new user:
- Open Mi Fit or Zepp Life.
- Go to Profile β Devices β Your Libra β User Management.
- Click Add User and enter data (gender, age, height).
- Stand on the scales β they will automatically determine the new user by weight.
If the scales confuse users:
- π Remove old profiles and add them again.
- π Make sure that the difference in weight between users is at least 5 kg.
- π£ Weigh yourself alternately at intervals of 10 seconds.
For children under 10 or older adults over 80, body composition analysis may be inaccurate due to bioimpedance features, in which case disable the extended metrics in the profile settings.
