Connecting Xiaomi scales to Mi Fit: full instruction with expert advice

Why sync Xiaomi scales with Mi Fit and what it gives the user

Xiaomi's smart scales are not just a weight-measuring device; they analyze body composition, monitor changes, and integrate with the Mi Ecosystem ecosystem. But all of these features are only available when you connect to the Mi Fit app (or its updated version of Zepp Life in some regions), without synchronization, you'll only get basic weights on the scale screen — without history, graphs, or personalized recommendations.

Synchronization provides access to:

• 📊 Detailed statistics: fat percentage, muscle mass, body water level, bone mass, and even metabolic age.
• 📱 Automatic data storage: All measurements are captured in the cloud and available on a smartphone, tablet or PC.
• 👨‍👩‍👧‍👦 Multiplayer mode: up to 16 profiles on a single scale (ideal for a family).
• 🔄 Integration with other services: Google Fit, Apple Health, Strava, etc.

However, many users face problems when connecting for the first time: the scales are not found, the data is not saved, or the application gives an error. In this article, we will analyze all the steps of synchronization, from preparing devices to solving typical errors, and also reveal hidden Mi Fit settings that are not written in the official instructions.

Preparing for connection: what to do before synchronization

Before you start pairing, make sure all the preconditions are met, and neglecting this stage is the main cause of failure.

Here is the checklist of mandatory actions:

Install the latest version of Mi Fit (or Zepp Life) from the official store (App Store/Google Play)|

Turn on Bluetooth on your smartphone and make sure it works consistently |

Charge the scale (if the model has a battery) or insert new batteries (AAA)|

Delete old weight data in Mi Fit (if previously connected)|

Check the compatibility of the weight model with your smartphone (see the table below)-->

Outdated versions of Mi Fit (up to 4.6.0) may not support new weight models such as the Mi Body Composition Scale 2 or Xiaomi Smart Scale 2 Pro. Update the app even if it doesn't signal available updates.

⚠️ Warning: If your smartphone is running Android 8.0 or later, turn off battery optimization for Mi Fit in the phone settings before connecting the scales. Otherwise, the app may not see the device due to background limitations.

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

Now, to the synchronization process itself, follow the instructions in strict order, and skipping steps often leads to errors.

Step 1: Starting the pairing process

1. Open the Mi Fit app and log in (if you haven’t already).
2. Go to Profile → Devices → Add the device.
3. Select Libra category and find your model in the list. If there is no model, choose Another device.

Step 2: Activation of the scales

• 🔋 Turn on the scales by pressing them with your foot or button (depending on the model). 0.00 or a flashing indicator should appear on the screen.
• 📱 On your smartphone, confirm the start of the search for the device. The scales will emit an audible signal (in models with a speaker).
• 🔄 Wait 10-30 seconds until the app detects the scales. If the search is delayed, restart the process.

Step 3: Set up a profile

After successful connection, Mi Fit will offer:

• 👤 Enter your basic data: gender, age, height, target weight.
• ⚖️ Select units of measurement (kg/pound/stones) – this setting is tied to the profile, not the weights.
• 🔔 Set up notifications for new measurements (optional).

Step 4. Test weighing

To make sure that the synchronization works:

1. Stand on the scale barefoot (for an accurate analysis of body composition).
2. Wait for the stabilization of the readings on the scale screen (the ✓ icon or tick).
3. Check that the data appears in the Mi Fit app in the Measurements section.

💡

If the scales don’t transmit data to the app, try weighing twice in a row – sometimes the first measurement only serves to wake up the Bluetooth module.

Common mistakes and their solutions

Even with the correct following of the instructions, there can be failures. Let's look at the typical problems and how to fix them.

Mistake 1: Libra is not in Mi Fit

• 🔌 Check power: Replace batteries or charge the battery (for models with USB-C).
• 📶 Make sure that Bluetooth is on and the scales are within 1 meter radius of the phone.
• 🔄 Reset the scales: Remove the batteries for 10 seconds or press the reset button (if any).
• 📱 Reinstall Mi Fit: Sometimes the app cache blocks the search for new devices.

Error 2: Data is not stored in the application

• 🌐 Check your internet connection — without it, the data is not synced to the cloud.
• 👤 Make sure you weigh under the same profile as the scales were attached to.
• ⏳ Wait 1-2 minutes — sometimes synchronization is delayed.
• 🔧 Update the firmware of the scales via Mi Fit (Device Settings → Software Update).

Mistake 3: Libras show wrong weight or are dropped

• ⚖️ Place the scales on a flat, hard surface (not on a carpet or soft coating).
• 🧘 Weigh yourself at the same time (in the morning on an empty stomach - optimal).
• 🔋 Calibrate the scales: to do this, stand on them and hold the weight for 5 seconds until the beep.

⚠️ Warning: If the scales stop turning on after you've connected, check the polarity of the batteries. In models with 4×AAA, it's not uncommon to short circuit when the batteries are not installed correctly.

Hidden Mi Fit features: what can be configured after connecting

Few people know, but Mi Fit has advanced settings that you can't see on the home screen, which allow you to calibrate scales more accurately and personalize the display of data.

1.Athlete mode

If you're active in sports, turn this mode on in your profile settings, and it adjusts your body composition algorithms to account for your increased muscle mass.

Profile → Settings → Athlete Mode

Adjustment of sensor sensitivity

In some weight models (e.g. Mi Body Composition Scale 2), sensor sensitivity can be changed to make more accurate measurements.

1. Go to the devices → Settings of the scales → Sensitivity.
2. Choose a high (for people with low weight) or low (for heavyweights).

3. Export of data to the CSV

Mi Fit allows you to upload your measurement history in CSV format for analysis in Excel or Google Sheets, a feature hidden in the web version of the service:

1. Go to account.huami.com and log in.
2. Select the Data section → Export.
3. Specify the period and confirm the export.

4. sync with Google Fit/Apple Health

To automatically transfer data from the scales to other fitness applications:

• 📱 On Android: Profile → Settings → Data Synchronization → Google Fit.
• 🍎 On iOS: Profile → Settings → Apple Health.

💡

Enabling sync with Apple Health or Google Fit allows you to use Xiaomi scale data in other fitness apps like Strava, MyFitnessPal or Nike Training Club.

How to connect Xiaomi scales to multiple phones

If you have multiple people using scales on different devices, you can connect them to multiple smartphones at the same time.

Method 1: Through the main account Mi Fit

1. On the main phone (where the scales are already connected), go to Profile → Devices → Settings → Share.
2. Select Add User and enter the second user’s email or phone number.
3. On the second phone, confirm the invitation to Mi Fit.

Method 2: Manual connection on each device

If the first method does not work (for example, due to regional restrictions), follow the standard connection procedure on each phone alternately. Xiaomi scales support up to 16 different profiles, but can be synced with 3-5 devices at the same time (depending on the model).

⚠️ Warning: When you connect scales to a new phone, do not remove them from the old device in Mi Fit. This will result in the reset of all stored data on the scale.

Alternative applications for weights Xiaomi

If Mi Fit doesn’t suit you (for example, due to limited functionality or regional locks), you can use third-party apps, which often offer more detailed analytics and flexible settings.

1.Zepp Life (formerly Mi Fit for some regions)

The official app from Huami (a device developer for Xiaomi) supports all the same features, but with an updated interface.

2. Mi Scale (informal)

Application from third-party developers with advanced features:

• 📈 More detailed graphs of changes in body composition.
• 🔧 Manual calibration of scales.
• 🌍 Supports metric and imperial systems without region-specific reference.

⚠️ Important: Unofficial applications may not support new weight models. Check compatibility on the project page before using.

3. Health Sync

A universal synchronizer that transfers data from Xiaomi scales to Google Fit, Apple Health, Samsung Health and other services. Useful if native synchronization in Mi Fit is unstable.

💡

For maximum accuracy, always weigh yourself at the same time of day, preferably in the morning after going to the toilet and before breakfast, which minimizes the impact of external factors (food, water, physical activity) on the results.
