Smart scales Xiaomi: full instructions for setting up and connecting to a smartphone

Xiaomi’s smart scales are not just a weight measurement device, but a full-fledged health control assistant. They analyze body composition (muscle, fat, water), sync with the Mi Fit app and integrate into the Mi Home ecosystem. But to make the device work correctly, it needs to be properly configured. In this article, detailed instructions for connecting, calibrating and solving typical problems.

We’ll go through all the steps from unpacking and first powering, to fine-tuning your user profile and firmware updates, focusing on syncing with iPhone and Android, as the connectivity algorithms differ, and learn how to lose weights to factory settings if they’re no longer responsive to commands, and what hidden features are available in recent versions of the software (e.g., Family Mode for Multiple Users).

1.Preparation for the first use: what is included in the kit and how to include scales

Before setting up, check the configuration. In the box with smart weights Xiaomi Mi Body Composition Scale 2 (or other models of the series) should be:

• 📦 The scales themselves with a protective film on the touch panel
• 🔋 4 type batteries AAA (Sometimes in a package, sometimes purchased separately)
• 📄 Short instructions in several languages (Russian is not always available)
• ⚠️ Warranty card (if purchased in the official store)

If you don't have batteries, use alkaline (not rechargeable!) Xiaomi scales are sensitive to the type of battery: cheap salt batteries can cause measurement failures. Install them in a compartment on the back, observing polarity (marked with icons) + and −).

Once the batteries are installed, the scales will automatically turn on, with the greeting "Hi" or flashing "0.0" on the display.

1. Check the density of the batteries (sometimes the contacts are not pressed).
2. Press the scales with your foot - the pressure sensor activates the display.
3. If nothing happens, remove the batteries for 30 seconds and re-insert them.

2.Installation of the Mi Fit application: version selection and account registration

For smart scales, you need to use the Mi Fit app (formerly called Mi Health) to download it:

• 📱 App Store for iOS (requires iOS 12.0 and later)
• 🤖 Google Play for Android (Android 6.0)+)
• 🌐 Xiaomi official website (if your region is blocked in app stores)

Once installed, start Mi Fit and register for Xiaomi (or log in through an existing one). Importantly, the balance binding is mandatory, without it, data will not be stored in the cloud. If you already have an account for other Xiaomi devices (such as a smartphone or bracelet), use it.

When registering, please provide real data:

• 👤 Gender (male/female) – affects the algorithms of body composition analysis.
• 📏 Growth - necessary for calculating the body mass index (BMI).
• 🎂 Date of birth – determines the age of fat / muscle.
• 🏃‍♂️ Activity level (sedentary/moderate/active) – adjusts daily goals.

💡

If you made a mistake in entering height or weight in your profile, correct the data in your Profile. → Edit → Basic information: Inaccurate parameters will distort the results of body composition analysis.

3. Connecting scales to a smartphone: step-by-step instructions for Android and iOS

The connection algorithm is the same for all Xiaomi smart scale models, but there are nuances for different OSes.

For Android:

1. Open Mi Fit and tap on the icon "+" top-right.
2. Select "Add device" → "Libra".
3. Click "Connect" and allow the app to access Bluetooth and Locations (required!).
4. Stand on the scales - on the display will appear "PAR" (pairing).
5. Wait for the synchronization to be completed (it will take 10–30 seconds).

For iOS (iPhone):

1. Turn on Bluetooth in your iPhone settings.
2. Launch Mi Fit and go to Profile → Add the device".
3. Select "Libra" and confirm the connection request.
4. Stand on the scales - on the screen of the smartphone will appear a request for pairing (tap "Confirm").
5. If the scales are not, restart Bluetooth on the iPhone.

After the successful connection, the app will display a device card with the latest measurements, if the sync is interrupted:

Check the battery charge (replace if necessary)

Make sure that Bluetooth is on on your smartphone

Re-launch the Mi Fit app

Remove the device from the list and add again

Update the firmware of the scales (see Section 5)

4. User profile setting and weight calibration

Accurate measurements require:

1. Create a user profile in Mi Fit (if you have multiple users).
2. Calibrate the scales – especially after transporting or replacing batteries.
3. Specify the target weight to track progress.

How to add a second user:

1. In the app, go to "Profile" → Devices → Your scales".
2. Tap "User management" → "Add".
3. Enter the new user’s data (gender, height, age).
4. Ask him to stand on the scale – the device automatically recognizes the user by weight (with an error). ±2 kg).

Calibration of the scales:

If the scales show inaccurate values (for example, the weight "jumps" or differs from the mechanical scale by 1-2 kg), calibrate:

1. Make sure that the scales are on a flat, solid surface (not on the carpet!).
2. Stand on the scale and wait for a stable reading.
3. Compare the result with the control weights (pharmacy or mechanical).
4. If the difference is more than 0.5 kg, reset the settings (press the reset button on the back for 5 seconds) and reconnect.

5. Firmware Update: Why It Matters and How to Do It

Xiaomi's smart scale firmware is responsible for measuring accuracy, stability of communication with Mi Fit and support for new features. Updates are released every 3-6 months.

1. Open Mi Fit and go to Profile → Your scales".
2. Tap on three points "⋮" → "Update firmware".
3. If a new version is available, confirm the installation.

The update process takes 2-5 minutes. Don't interrupt it, it can cause the device to crash. Once updated, the scales will automatically reboot.

Critical information: If after the update the scales stopped turning on, reset to factory settings (press the button on the back for 10 seconds).

💡

Updating firmware through Mi Fit is the only official way. "Manual" firmware from third-party sites can damage the device and deprive you of warranties.

6. Resetting and troubleshooting

If Xiaomi scales are not working correctly (not synchronized, show errors or not included), reset:

1. Turn the scales over and find a small hole with the inscription RESET (near-battery).
2. Take a paperclip or toothpick and press the button inside the hole for 5-10 seconds.
3. The scales will squeak and reboot (the “Hi” will appear on the display).

After the reset, all user data will be deleted, and the scales will return to the factory settings. They will need to be reconnected via Mi Fit.

Common mistakes and their solutions:

• ❌ "Err" - overload (maximum weight for most models - 150 kg).
• ❌ "Lo" - weight less than 10 kg or unstable surface.
• ❌ "---" — Batteries are dead or no communication with the phone.
• ❌ Libras don’t store data – check your internet connection (data synced to the cloud).

💡

If the scales show an error of "Err" at normal weight, check if they are on a soft carpet.

7. hidden features of Xiaomi smart scales

In addition to standard weight and body composition measurements, Xiaomi scales support additional features:

• 👶 Pregnancy mode - tracks weight gain without taking into account fat mass (included in the profile settings in Mi Fit).
• 🏠 Mi Home integration – data is automatically transferred to Xiaomi smart home (you need to connect both apps to one account).
• 📊 Export of data – the history of measurements is unloaded to CSV or synchronized with Google Fit/Apple Health.

To activate the pregnancy regimen:

1. In Mi Fit go to "Profile" → Settings → Special regimes".

3. Libra will ignore fat mass when calculating the norms.

To sync with Google Fit:

1. In Mi Fit, open "Profile" → Settings → Connected applications".
2. Select Google Fit and log in.
