How to set up Xiaomi Mi smart scales: from unpacking to synchronization with the application

Why Xiaomi Smart Scales Need Customization – and What Happens If You Miss It

Did you buy Xiaomi Mi Smart Scale or Mi Body Composition Scale 2, but the scales show inaccurate weight, don't sync with your smartphone or don't turn on at all? 90% of the time the problem lies in the wrong initial setup. Unlike mechanical counterparts, Xiaomi smart scales require attachment, sensor calibration and firmware updates - otherwise they work like regular floor scales without "smart" features.

Without setting up, you will lose:

• 📊 Analysis of body composition (percentage of fat, muscle, water, bone mass)
• 📱 Automatic sync with Mi Fit, Zepp Life or Apple Health
• 👨‍👩‍👧‍👦 Multiplayer mode (the scales will not recognize different family members)
• 📈 Change history and schedule of progress in the annex

In this article, you can find a step-by-step guide with a photo on how to properly adjust the Xiaomi Mi scales of any model (including the Mi Scale 1/2, Smart Scale 2 and Body Composition Scale 2), avoid typical errors and restore performance if something goes wrong.

Step 1: Unpacking and preparing the scales for work

Before setting up, check the configuration. In the box with the Xiaomi Mi scales should be:

• 📦 The scales themselves (with a protective film on the sensors)
• 🔋 4 batteries AAA (In some models, a built-in battery)
• 📄 Short instructions in several languages (Chinese) + English)
• 🔑 Key to remove the battery compartment cover (if provided)

⚠️ Warning: Don't throw the tape off the sensors right away! It protects the sensors from damage during transportation.

How to prepare the scales for setting:

1. Install batteries (or charge the built-in battery via USB-Type C).
2. Put the scales on a flat, hard surface (not on a carpet!).
3. Turn on the scales by pressing the platform with your foot - should appear 0.0 or --.--.
4. Wait for the sound signal (squeak) – this means that the scales are ready to pair.

💡

If the scales are not turned on, check the polarity of the batteries. In the Mi Scale 2 and newer models, the contacts are arranged in a non-standard way - the "+" and "-" can be confused!

Step 2: Install and configure Mi Fit or Zepp Life

Xiaomi Mi scales work through branded applications. Choose one of them:

How to install and configure the application:

1. Download Mi Fit (Android/IOS) or Zepp Life.
2. Register with Xiaomi Account, Google or Apple ID.
3. In the application menu, select Profile → Add device → Libra.
4. Follow the instructions on the screen for pairing.

⚠️ Note: If you add a device error "Can't connect", check:

• 📶 Is Bluetooth enabled on your smartphone.
• 📱 Have you allowed the app to access geodata (required for Android 10)+).
• 🔄 Reset the scales (remove the batteries for 10 seconds).

Step 3: Calibration of the scales – why it is important and how to do it right

Calibration is a fine-tuning of sensor accuracy. Without it, scales can show weight with an error of up to ±500 grams. In Xiaomi Mi, calibration is automatically done at the first weighing, but sometimes manual adjustment is required.

How to calibrate the scales:

1. Put the scales on a flat surface (tiles, laminate, countertop).
2. Stand on the scales with bare feet (socks distort the reading).
3. Stand still for 5-7 seconds until a stable value appears on the screen.
4. Compare the result with the reference weights (if any) If the difference is greater than ± 200 g, repeat the procedure.

For Body Composition Scale 2 models, the calibration includes personal data entry:

• 👤 Paul
• 📏 Growth (in cm)
• 🎂 Age.
• 🏃 Activity level (sedentary, moderate, active)

Step 4: Sync your data with other services (Google Fit, Apple Health, S Health)

To ensure that the data from the scales automatically gets into other fitness applications, set up integration:

In Mi Fit:

1. Open Profile → Settings → Account Management.
2. Select the service (Google Fit, Apple Health or S Health).
3. Log in and allow access to the data.

In Zepp Life:

1. Go to Profile → Settings → Connected applications.
2. Activate the right services.

⚠️ Note: When synchronized with Apple Health, body composition data (fat, muscle) may not be transferred - this is a restriction of Apple, not Xiaomi.

💡

For an accurate analysis of the composition of the body, weigh yourself at the same time (preferably on an empty stomach in the morning) and in the same clothes (or without it).

Step 5: Set up a multiplayer mode

Xiaomi Mi scales support up to 16 users in one app.To add a family member:

1. Open the app (Mi Fit or Zepp Life).
2. Go to Profile. → User management.
3. Click Add User and enter data (height, age, gender).
4. Ask the person to stand on the scales – they will automatically be attached to their profile.

How do scales recognize users?

The algorithm analyzes:

• 📏 Weight (with error) ±1 kg)
• ⚖️ Mass distribution (centre of gravity)
• ⏱️ The last time of the weighing (if it has passed) >12 hours, may request confirmation)

If the scales confuse users:

• 🔄 Ask each to stand on the scale in turn (with an interval of 10 seconds).
• 📱 Manually select a profile in the application after weighing.

Step 6: Update the firmware of the scales - whether and how to do

Xiaomi Mi's firmware scales are updated automatically through the app, but sometimes manual updates are required.

• 🐛 Synchronization bugs
• 📏 Measurement errors
• 🔋 Optimizing battery consumption

How to update firmware:

1. Open the app and connect to the weights.
2. Go to Profile → My devices → [Name of scales] → Update firmware.
3. If a new version is available, click Update.
4. Do not disconnect the scales from the power supply and do not close the application until it is completed (takes 2-5 minutes).

💡

Once the firmware update is up, the scales can show a "-.--" for 10 to 15 seconds -- that's OK. Just wait or restart the device.

Step 7: Troubleshooting – What to Do If the Scales Are Not Working

Typical problems and their solutions:

If the scales are no longer synchronized after the application update:

1. Remove the scales from the device list in Mi Fit/Zepp Life.
2. Reboot the phone.
3. Then add the weights again (as in the first setup).
