How to connect Xiaomi scales to the Mi Fit application: full instructions with photos and tips

Introduction: Why synchronize Xiaomi scales with Mi Fit?

Xiaomi’s smart scales (including the popular Mi Body Composition Scale 2, Smart Scale 2, and Body Fat Scale) are not just a weight measurement device; they analyze 13 key body parameters, from body mass index (BMI) to muscle and bone mass. But all of this analytics is only available when you connect to the Mi Fit mobile app (or its Zepp Life counterpart for new models). Without synchronization, you will only get numbers on the screen — without history, graphs, and recommendations.

The connection process seems simple, but many users are faced with errors: scales are not in the application, data is not saved, or the device shuts down after a few days. In this article, we will analyze the step-by-step instructions for all current Xiaomi scale models, and also solve typical problems. If you just unpacked the box or try to reconnect the old scales, here you will find the answers.

What scales Xiaomi supports connecting to Mi Fit?

Not all Xiaomi smart scales work with Mi Fit. After the rebranding in 2021, some devices have moved to the control of the Zepp Life app (formerly Amazfit), Below is the current compatibility table for 2026:

⚠️ Note: If your model is released after 2022, it most likely only works with Zepp Life. Trying to connect it to Mi Fit will lead to the error "Device is not supported." Check the box or the official Xiaomi website for clarification.

Older models (before 2020) may need to update the firmware through the app. If the scales are not determined, try first updating the Mi Fit to the latest version in Google Play or the App Store.

Preparing for connection: what to do before synchronization

Before you start setting up, follow a few mandatory steps that will eliminate 90% of the typical errors:

• 📱 Install the app: Download Mi Fit (Android / iOS). For new models - Zepp Life.
• 🔋 Charging the scales: Make sure batteries (usually 4) are in place×AAA) If the scales aren't on, try replacing the batteries with new ones.
• 📶 Bluetooth and location: Turn on Bluetooth and allow the app to access geodata (required to search for devices).
• 👤 Profile in Mi Fit: Fill in your data on the app: height, age, gender. Without it, body analytics will be inaccurate.

Critical detail: Xiaomi scales do not have a physical power button; they only activate when you push your foot on the platform. If the device does not respond, check the contacts of the batteries or try to stand on the scale with force (sometimes the sensors require a load of >10 kg).

Install Mi Fit (or Zepp Life)

Put the batteries in the scales

Turn on Bluetooth on your phone

Allow geodata for Mi Fit

Fill in the profile (height, weight, age)-->

If you are not connecting the scales for the first time (for example, after resetting your phone), remove the old device from the list in Mi Fit → Profile → My devices. Re-addition without deleting can cause an ID conflict.

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

Follow the algorithm below. If there is an error at some point, go to the "Problem Solutions" section.

1. Step 1. Start the process Open Mi Fit, go to Profile → Add Device. Select Libra.
2. Step 2. Activate the scales Stand on the scale platform with your bare feet (the socks distort the sensor readings). The scales should show a connection animation (Bluetooth flashing icon).
3. Step. 3. In the app, click "Start Search." Scales should appear in the list as "Mi Scale". [XXXX]", where XXXX — last-minute MAC-address.
4. Step 4: Synchronize Confirm Connection. Wait for the message "Device added." Libra will automatically perform the first measurement.

🔹 Important: If the scales are not, exit the Add Device section, restart the Mi Fit and try again. Sometimes it helps to restart the phone.

Once successfully connected, the scales will automatically sync with each weighing, and the data will appear in the Measurements section of Mi Fit in 5-10 seconds.

Setting up profile and calibrating weights for accurate data

Even after connection, the scales may show inaccurate values if:

• 📏 The profile indicates incorrect growth (BMI error up to 15%).
• 👕 Weigh yourself in clothes or shoes (let us only allow a light robe).
• 🕒 Less than 2 hours after eating/workout (water level jumps in the body).

To minimize errors:

1. Open Mi Fit → Profile → Edit and refine growth to within a centimeter.
2. Weigh yourself in the morning on an empty stomach after going to the toilet.
3. Use the Guest mode for family members (each must have a profile in Mi Fit).

⚠️ Note: Xiaomi scales are calibrated automatically when first turned on. If you have transferred them to an uneven surface (carpet, tiles with drops), the readings can "float." Check the floor level or use a solid substrate.

💡

For maximum accuracy, weigh at the same time of day. Mi Fit algorithms take into account daily weight fluctuations and adjust schedules automatically.

Problem Solving: Scales are not connected or data is not stored

Let’s look at the most common mistakes and ways to eliminate them:

If the scales are connected, but after a day or two disappeared from the list of devices, try:

1. Remove them from Mi Fit → Profile → My devices.
2. Remove the batteries for 10 minutes, then insert back.
3. Repeat the connection process again.

💡

If the Xiaomi Smart Scale 3 scales don't connect to the Mi Fit, that's fine - they only work with Zepp Life.Don't waste time looking for workarounds: update the app.

Sync with other services: Google Fit, Apple Health

Data from Mi Fit can be automatically exported to Google Fit (Android) or Apple Health (iOS) to:

• 📊 See all health statistics in one place.
• 🔄 Sync data with other fitness apps (e.g. MyFitnessPal).
• 📱 Use voice assistants to analyze progress.

To enable synchronization:

1. Open Mi Fit → Profile → Settings → Data Synchronization.
2. Choose the right service (Google Fit or Apple Health).
3. Log in and allow access to the data.

⚠️ Note: The first time you sync, you may have duplicated records. Delete the repeating data manually in the target application (e.g. Google Fit).

If the synchronization is not working:

• Check that the phone settings allow Mi Fit to access the "Physical Activity".
• Update both apps (Mi Fit and Google Fit/Apple Health) to the latest versions.
• Restart the phone – sometimes background processes block data exchange.
