Setup Xiaomi smart scales with phone: from connection to calibration

Why Xiaomi Smart Scales Need to Sync with Your Phone – and What This Ligament Gives

Xiaomi’s smart scales (Mi Smart Scale 2, Xiaomi Body Composition Scale 2, Mi Body Composition Scale, and others) are not just a weight measurement device; they analyze up to 13 body parameters, from BMI to muscle and bone mass, but all of this analytics is only available when you’re tied to a smartphone. Without synchronization, you’ll only see weight numbers on the scale screen — without history, dynamics, or recommendations.

Connecting to your phone via the app (Mi Fit or Zepp Life) allows you to:

• 📊 Track the dynamics of changes in weight, fat mass and muscles in the charts.
• 👥 Create multiple profiles for family members (libras automatically recognize the user).
• 🔗 Integrate data with Google Fit, Apple Health or Strava.
• 📱 Receive notifications of goals or critical changes (such as sudden weight gain).

However, many users face problems: scales do not connect to the phone, data is not saved, or the application does not see the device, most often due to improper Bluetooth configuration, outdated firmware of the scales or errors in the user profile. In this article, we will discuss all the current ways of synchronization for 2026, including bypassing typical errors.

Preparing for connection: what to do before synchronization

Before you start setting up, make sure that the basic conditions are met:

1. Most Xiaomi models run on 4 batteries AAA, But some (like the Mi Smart Scale 2) have a built-in battery: 🔋 Positive and negative battery contacts (they must match the marking in the compartment). 🔌 USB-Type-C charging cable for models with built-in battery.

Phone compatibility.

Android 5.0+

iOS 10.0+

Bluetooth and location.

Also remove older versions of Mi Fit or Zepp Life apps if they were installed earlier. Conflicts between versions are a common cause of sync failures.

Step-by-step: how to connect Xiaomi scales to the phone

The synchronization process differs depending on the weight model and the version of the application. Consider the universal algorithm for Mi Fit (relevant to Android and iOS):

1. Install the application. Download Mi Fit from official sources: 🤖 Google Play for Android). 🍎 App Store (for iOS).

⚠️ Attention: Do not use APK-files from third sites – they may contain malicious code or outdated versions of Bluetooth protocols.

Account registration.

Launch Mi Fit and create a Xiaomi account (or log in via Google/Apple ID). Without an account, data will not be saved to the cloud.

Adding a device.

Click Profile → Add device → Libra. Choose your model from the list. If you don't have one, choose Another device.

Libra activation.

Stand on the scales (with your bare feet, on a flat surface). In 3-5 seconds, your weight will appear on the screen, and in the application, a connection request. Confirm it.

Setting up a profile.

Type in the exact data: sex, age, height and activity level, and the accuracy of the fat mass and muscle calculation depends on it.

If you use Zepp Life, the algorithm is similar, but the interface is different. For example, in Zepp Life, you need to select the Devices section first and then click Add.

Solving common connection errors

Even with the right setup, Xiaomi scales may not connect. Consider typical problems and ways to fix them:

If the scales are connected, but show the wrong weight, perform the calibration:

1. Stand on the scale and wait for a stable reading.
2. In the app, go to the Device Profile → Calibration.
3. Follow the instructions on the screen (usually confirm the current weight).

💡

If the scales are connected but the data is not updated, try logging out of your Mi Fit account and re-signing in, often solving synchronization problems.

How to Set Up Multiple Profiles for Family Members

One of the key benefits of Xiaomi’s smart scales is that it supports multiplayer, automatically recognizing the user by weight (with an error of ±2 kg) and saving the data to the appropriate profile to add a new user:

1. Open Mi Fit or Zepp Life.
2. Go to Profile → Devices → Your Libra → User Management.
3. Click Add User and enter their data (height, age, gender).
4. Ask a family member to stand on a scale – the app will automatically tie their weight to a new profile.

To delete your profile, go to User Management, select an unnecessary account, and click Delete. That user's data will be erased from your history.

💡

If the scales don’t recognize the user, try to stand on them 2-3 times in a row – the machine learning algorithm adapts to your weight.

Synchronize data with other services (Google Fit, Apple Health, Strava)

To automatically transfer Xiaomi scale data to Google Fit, Apple Health or fitness trackers (such as Strava), you need to configure integration in the application:

1. For Mi Fit: Go to Profile → Settings → Accounts and Sync. Select the service (Google Fit, Apple Health) and log in.

Important nuances:

• 🔄 Synchronization works only one way – from scales to third-party services. Backward transfer (for example, from Google Fit to Mi Fit) is impossible.
• ⏳ Data is updated with a delay of up to 10-15 minutes. For instant synchronization, open the Mi Fit app and update the data manually.

If the synchronization is not working:

1. Check if data transfer is enabled for a specific parameter (in the integration settings).
2. Update the Mi Fit/Zepp Life app to the latest version.
3. Reconnect your service account (for example, untie and re-link Google Fit).

Update of the firmware of the scales and reset to factory settings

If the scales are unstable (for example, they often turn off or show errors), the cause may be outdated firmware, which can be updated through the application:

1. Open Mi Fit or Zepp Life.
2. Go to Profile → Your Devices → Weights Settings → Update Firmware.
3. If a new version is available, click Update and wait for the process to complete (the scales should be near the phone!).

If the update does not help or the scales are hanging, reset to factory settings:

1. Remove the batteries from the scale for 30 seconds.
2. Hold the power button (if any) for 10 seconds.
3. Remove the scales from the list of devices in the application and connect again.

⚠️ Warning: Reset removes all stored user profiles and calibration data, and then you have to reconfigure the scales and enter the parameters of each family member.

If the scales are not turned on after reset, check:

• 🔋 Proper installation of batteries (contacts should not be oxidized).
• 📱 Phone compatibility (on some Huawei or Honor models, Mi Fit background work may be blocked).
• 🌐 Internet availability (first synchronization requires access to Xiaomi servers).

Tips for accuracy measurements and weight care

To make Xiaomi’s weights as accurate as possible, follow these guidelines:

• ⏰ Measurement time. Weigh yourself on an empty stomach in the morning after going to the toilet. In the evening, weight can vary by 0.5-1.5 kg due to the fluids and food consumed.
• 👣 Stand still, spread the weight evenly on both legs, don't lean on the wall or furniture.
• 🧘 The scales should be on a flat, hard surface (tile, laminate) and the carpet or the soft floor will distort the readings.
• 🚿 Clean contacts. Wipe the electrodes on the scales with dry tissue 1 time per week.Sweat or moisture can disrupt conductivity.

To extend the service life of the scales:

• 🔋 Remove batteries if you do not use the scales for more than 2 months.
• 🚫 Do not put on the scales objects heavier than 150 kg (maximum load for most models).
• 🌡️ Avoid direct sunlight and temperatures below 0°C or higher than 40°C.

If the scales start to show overvalued or undervalued values, recalibrate (instructions in the "Error Solving" section) or reset them to factory settings.

💡

For a more accurate analysis of body composition, weigh yourself at the same time of day and in the same clothes (or without).
