How to connect Xiaomi scales to Mi Fit: full instructions with pictures and tips

Xiaomi's smart scales are not just a weight measurement device, they're a full-fledged health tracking tool. They analyze body composition, store measurement history, and sync with the mobile app. But what if the scales don't connect to the Mi Fit? Or the app doesn't see the device? This article will help you understand everything from the first setup to solving typical problems.

Many users have difficulty connecting for the first time: scales are not determined, data is not saved, or an application gives an error. Most often, the problem lies in the wrong sequence of actions or missing details (for example, forgot to turn on Bluetooth), we will analyze each step in detail, pay attention to the compatibility of models and give tips for optimizing the work.

If you just bought Xiaomi Mi Smart Scale 2 or Xiaomi Body Composition Scale 2, this guide will be your guide, and for owners of older models (for example, the first version of the scale), we will separately specify the features of the connection.

What Xiaomi scales are compatible with Mi Fit?

Not all Xiaomi smart scales work with the Mi Fit app. Here's the current list of supported models for 2026:

• 🔹 Xiaomi Mi Smart Scale 2 is the most popular model with 13 body parameters analysis.
• 🔹 Xiaomi Body Composition Scale 2 – improved version with more accurate sensors.
• 🔹 Xiaomi Mi Body Composition Scale (First version) – requires firmware updates.
• 🔹 Redmi Smart Scale – budget version with basic features.

Xiaomi Mi Scale (first generation) scales are not officially supported by Mi Fit since 2022, but need to use the Mi Home app or update the firmware manually.

Also look at regional versions. For example, Xiaomi Mi Smart Scale 2 for the Chinese market may have different software and not sync with the global version of Mi Fit. Check the label on the box: if there is an inscription CN, the device is designed for China.

Preparing for the connection: what to do before the start

Before you start synchronizing, follow a few mandatory steps that will save time and eliminate common errors.

1. Install or update the Mi Fit app. Download it from the official store:

• 📱 Google Play for Android
• 🍎 App Store for iOS

Minimum requirements:

• 📱 Android 6.0 and higher
• 🍎 iOS 12.0 and higher
• 🔄 Bluetooth 4.0+

2. Register a Xiaomi account. Without it, scales can't save data to the cloud. If you don't have an account, create it directly from Mi Fit or from account.xiaomi.com.

Check the scales:

• 🔋 Make sure that the batteries are installed (usually 4).×AAA).
• 📶 Turn on the scales by pressing them with your foot - should appear 0.0 or --.--.
• 📱 Place the scales on a flat, solid surface (not on the carpet!).

Important: if the scales show a Lo error, it means the batteries are discharged. Replace them, even if they are new, factory defect is possible.

Step-by-step: how to connect the scales to Mi Fit

Now, let's get to the synchronization process itself. Follow the instructions in strict order.

Step 1. Open the Mi Fit app and log in to your account. On the home screen, tap the Profile icon (in the lower right corner), then select Add Device.

Step 2. Select Libra category. Search your model in the list (e.g. Mi Smart Scale 2). If your model is not available, select Another device and enter the name manually.

Step 3: Turn on Bluetooth on your phone and allow Mi Fit access to geodata (required for Android 10+!) on your iPhone, you also need to allow notifications.

Step 4. Follow the hints in the app:

1. Stand on the scales - on the display will appear --.-- or CONN.
2. Wait for vibration and sound signal (if any).
3. On the phone screen will appear a request for connection – confirm it.

Step 5: Enter your data (gender, age, height, weight) to correctly analyze body composition, and if you skip this step, your fat/muscle readings will be inaccurate.

Now the scales are automatically synchronized with the Mi Fit at each weighing, and the data will be stored in history and displayed in graphs.

Profile setting and weight calibration

Once connected, you need to calibrate the scales and set up a profile for accurate measurements.

Sizing:

• 🔧 Stand on the scales with bare feet (socks distort readings).
• 📏 Spread the weight evenly on both legs.
• 🕒 Wait 3-5 seconds for the stabilization of the readings.

If the scales show a knowingly incorrect weight (for example, +10 kg), reset them to the factory settings: press and hold the switch on 10 seconds.

2.Setting up a profile in Mi Fit:

• 👤 Make sure that the correct growth is indicated (error). ±1 cm affects the calculation of BMI).
• 🎯 Choose a goal: losing weight, gaining weight or maintaining a shape.
• 📅 Include reminders of weighing (optional).

3. Additional settings (under Device → Weight settings):

• 🔄 Autosynchronization with Google Fit/Apple Health.
• 👨‍👩‍👧‍👦 Family mode (up to 16 profiles on one scale).
• 📊 Display of metrics: kg/pounds/groans.

💡

For maximum accuracy, weigh at the same time (preferably on an empty stomach in the morning) and in the same clothes (or without it).

Common mistakes and their solutions

Even with the right connection, there can be failures, and let's look at the typical problems and how to fix them:

If the scales are connected, but the data is not stored:

1. Check the Internet connection (data is synchronized via the cloud).
2. Update your Mi Fit to the latest version.
3. Leave the account and log in again.

⚠️ Warning: If the scales are reset after the battery is replaced, they need to be reconnected like new ones.

Sync with other apps (Google Fit, Apple Health, Strava)

Mi Fit alone isn't enough to fully track health, and fortunately Xiaomi scales can transfer data to other services. Here's how to set it up:

1. sync with Google Fit (Android):

1. Open Mi Fit → Profile → Settings → Data Synchronization.
2. Select Google Fit and log in.
3. Allow access to data on body weight and composition.

2. sync with Apple Health (iPhone):

1. Go to Profile → Settings → Apple Health.
2. Turn on switches for Weight, Fat Percentage and other metrics.
3. Confirm access in the pop-up window.

3.Export to Strava or MyFitnessPal:

• 🔗 Use Health Sync (Android) or Apple Health (iOS).
• 📤 In Mi Fit, enable export to Google Fit, then configure import from Google Fit to Strava.

⚠️ Note: when synced with Apple Health, body composition data (fat, muscle, water) may not be displayed correctly.This is an iOS limitation - use the original Mi Fit app for detailed analytics.

How to lose Xiaomi scales to factory settings

If the scales start to glittle, show errors or don't connect, resetting will help. Here's how to do it for different models:

Mi Smart Scale 2 and Body Composition Scale 2:

For the Redmi Smart Scale:

Once reset, the scales will become "like new" - they will need to be reconnected to the Mi Fit. The previous data in the application will be saved, but the history of measurements on the scales themselves will be zeroed.

💡

Resetting the scales only removes the phone's communication settings.The data in Mi Fit remains intact unless you have deleted the device from your account.
