How to connect Xiaomi floor scales to a smartphone: from synchronization to calibration

Why Xiaomi Smart Scales Require a Phone Connection – 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:

  • πŸ“Š Detailed statistics - not only weight, but also the percentage of fat, muscle mass, water in the body, bone mass and even metabolic age.
  • πŸ“± Automatic sync with Google Fit, Apple Health or Mi Fitness for comprehensive health analysis.
  • πŸ‘¨β€πŸ‘©β€πŸ‘§β€πŸ‘¦ Multiplayer mode – scales recognize up to 16 users by weight and store data for each in a separate profile.
  • πŸ“ˆ Visualization of progress – 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):

ModelBluetooth supportCompatible annexesMax. Weight, kg.
Mi Body Composition Scale 2βœ… Bluetooth 5.0Mi Fit, Zepp Life150
Xiaomi Smart Scale 2βœ… Bluetooth 4.2Mi Fit150
Mi Smart Scale (1st generation)βœ… Bluetooth 4.0Mi Fit (outdated firmware)150
Xiaomi Body Fat Scaleβœ… Bluetooth 5.0Zepp Life, Mi Fitness180

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.

⚠️ 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:

  • πŸ“± Android: version 6.0 and higher, Bluetooth 4.0 support+.
  • 🍎 iOS: iPhone 5s and newer, iOS 10.0 or higher.

If you have a Xiaomi or Redmi smartphone, turn on the β€œDual Bluetooth Connection” 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:

  1. Install Mi Fit from Google Play or App Store. Sign up or sign in via your Xiaomi/Google/Apple account.
  2. 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.
  3. Open Mi Fit, go to Profile β†’ Add device β†’ Libra.
  4. 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).
  5. Stand on the scale with your bare feet. A flashing Bluetooth indicator will appear on the scale screen, which is the connection signal.
  6. 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:

  • πŸ”„ Reboot Bluetooth on your phone (turn off/on).
  • πŸ“± Remove the Mi Fit app cache in your phone settings.
  • πŸ”‹ Replace batteries in weights even if the indicator is on.

⚠️ 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:

  1. Download Zepp Life (Android/iOS)
  2. Sign up or sign in through your Xiaomi account.
  3. Go to the Devices. β†’ Add β†’ Libra.
  4. Select a model and follow the on-screen prompts (similar to Mi Fit).

Zepp Life offers more detailed reports, including:

  • πŸ“… Weekly reports with nutritional recommendations.
  • πŸ‹οΈ Integration with training (stepmers, treadmills).
  • 🩺 Tips for improving body composition based on AI analysis.
What data does Zepp Life transfer?
Xiaomi scales send to the app 13 parameters: 1. Weight (with an accuracy of 50 g) 2. Body mass index (BMI) 3. Fat percentage 4. Muscle mass 5. Bone mass 6. Water level 7. Visceral fat 8. Basic metabolism (calories at rest) 9. Metabolic age 10. Protein mass 11. Basic metabolic rate 12. Ideal weight (calculation) 13. Body type (classification)

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 causeDecision
Libras not includedBatteries discharged or contacts oxidizedReplace batteries, wipe contacts with alcohol
App doesn't find scalesBluetooth is off or scales are not in pairing modeTurn on Bluetooth, stand on the scale to activate
The "failed to connect" errorConflict with another device in the memory of the scaleReset the scales to factory settings (hold the 10 sec button)
Data not storedNo internet or account failureCheck 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:

  1. Stand on the scale and wait for measurements.
  2. In the app, go to Device Profile β†’ Settings β†’ Calibration.
  3. Follow the instructions on the screen (you may need to enter the weight manually).

⚠️ 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:

  1. Open Mi Fit or Zepp Life.
  2. Go to Profile β†’ Devices β†’ Your Libra β†’ User Management.
  3. Click Add User and enter data (gender, age, height).
  4. Stand on the scales – they will automatically determine the new user by weight.

If the scales confuse users:

  • πŸ”„ Remove old profiles and add them again.
  • πŸ“ Make sure that the difference in weight between users is at least 5 kg.
  • πŸ‘£ 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.

FAQ: answers to frequent questions about Xiaomi weights

Can you connect Xiaomi scales to multiple phones at the same time?
Yes, but with limitations. Libras store data in the Xiaomi cloud, so all phones authorized under one account will see the measurement history. However, simultaneous Bluetooth connection is only possible to one device. To switch, turn off the scales in the Bluetooth settings of the first phone and connect to the second.
Why Xiaomi scales show different weights when weighed again?
100-300 grams is the norm for electronic scales: πŸ”‹ Low battery charge (replace them). 🌑️ Sudden temperature changes in the room. πŸ‘Ÿ Uneven weight distribution on the platform (stand in the center). To be accurate, weigh 2-3 times in a row and take the average value.
How to lose Xiaomi scales to factory settings?
Hold the on button (or touchpad) for 10-15 seconds until 0.0 appears on the screen. After reset, all user data will be deleted and the scales will return to their original settings.
Can I use Xiaomi scales without a phone?
Yes, but with limitations, the scales will only show the weight on the display, without analyzing the composition of the body, the data will not be stored in history.
How to export data from Mi Fit to Excel or Google Tables?
Open Mi Fit, go to Profile β†’ Health Data β†’ Export. Select period and format (CSV or PDF). The file can be opened in Excel or uploaded to Google Drive.

πŸ’‘

To maximize accuracy, weigh yourself at one time of the day, on an empty stomach and after using the toilet, which minimizes the impact of external factors on body composition.
