How to connect your phone to Xiaomi smart scales: instructions with photos and videos

Xiaomi’s smart scales are not just a weight measurement device, but a full-fledged health monitoring gadget. They analyze body composition (fat, muscle, water), synchronize data with a mobile app, and help track fitness or diet progress. However, many users face difficulties when they first connect: the scales are not on Bluetooth, the app does not see the device, or data is not stored. In this article, we will analyze all the ways of synchronizing, from basic settings to solving typical errors.

It’s important to understand that the connection process depends on the scale model (e.g. Mi Body Composition Scale 2 or Xiaomi Smart Scale 2) and the firmware version of the smartphone. We’ll look at the universal steps that are relevant for Android and iOS, and also focus on the nuances for old and new devices. If you just unpacked the box or are trying to reconnect the scales after a reset, this guide will help avoid common errors.

What Xiaomi scales support phone connection

Not all Xiaomi smart scales work with mobile apps, here’s the current list of compatible models (2026):

• 📱 Xiaomi Mi Body Composition Scale 2 is the most popular model with the analysis of 13 body parameters.
• 📱 Xiaomi Smart Scale 2 - budget version with basic functions (weight, BMI, fat mass).
• 📱 Xiaomi Mi Scale (first generation) – outdated model, but still supported.
• 📱 Xiaomi Mi Body Fat Scale – a special version for athletes.
• 📱 Xiaomi Mi Smart Scale Lite – a simplified model without a screen (data only in the application).

If your model is not included in the list, check its name on the box or in the documentation. Libras without Bluetooth support (for example, mechanical or simple electronic) can not be connected to the phone (CN-versions may require additional settings.

What applications are needed to connect

To synchronize the scales Xiaomi phone will require one of the official applications, the choice depends on the model of the device and the region:

Important: From 2023, Xiaomi will gradually migrate all devices to the Zepp Life platform, so it is better to use this application for new weights. If you have previously used Mi Fit, the data can be transferred to Zepp Life through the Xiaomi account (instruction below).

Before installing the application, check:

• 🔄 Android version (not lower than 6.0) or iOS (not lower than 12.0).
• 📶 Stable Internet connection (for authorization and loading of the firmware of scales).
• 🔋 Charging the battery of scales (if the model with a battery).

Step-by-step instructions: how to connect the scales to the phone

Consider a universal connection algorithm for Mi Body Composition Scale 2 and the Zepp Life application (for Mi Fit, the steps are similar).

Install the Zepp Life or Mi Fit app

Charge the scales (if the model with a battery)

Turn on Bluetooth on your phone

Place the scales on a flat surface (not on the carpet!)

-->

Step 1. Registration of an account

Open the app and create an account (via email, phone number or Google/Apple account) if you already have a Xiaomi account, sign in to it, making it easier to sync with other devices in the ecosystem (such as the Mi Band).

Step 2: Adding a device

In the main menu of the app, click Profile → Add device. Select Libra category and find your model in the list. If there is no model, select Other device.

Step 3: Synchronize over Bluetooth

Put the scales on a flat surface and step on them (or press the switch on button, if any). The scale should show 0.00 or a flashing Bluetooth indicator. In the application, click "Plug" and the phone will start searching for the device. The process can take up to 30 seconds.

Step 4: Calibration and profile setting

After connecting, the application will offer:

• 👤 Enter your height, age and gender (this is necessary for accurate calculation of BMI and body composition).
• ⚖️ Conduct a test weighing (step on the scale and wait for synchronization).
• 📊 Select goals (weight loss, weight gain, maintaining shape).

Step 5: Verification of the work

Step on the scale again, the data should automatically appear in the app. If this does not happen, reboot the Bluetooth on your phone (Settings → Bluetooth → Off / On) and repeat the weighing.

💡

If the scales don’t connect, try resetting them to factory settings: press and hold the on button (if any) for 10 seconds or remove/insert batteries.

What to do if the scales are not connected to the phone

Connection problems are usually due to one of three reasons: firmware incompatibility, Bluetooth conflict, or errors in application settings.

⚠️ Note: If you use an iPhone, make sure that the privacy settings are in place → Geolocation Services for the Mi application Fit/Zepp Life is allowed "On-Use" access. Without it, Bluetooth may not work smoothly.

Problem 1: Phone can't see scales via Bluetooth

First, check:

• 🔋 Charging scales (if model with battery) – discharged scales do not include Bluetooth.
• 📱 Phone compatibility: on Android 12+ iOS 15+ Additional permissions may be required for the application.
• 🔄 Bluetooth Reboot: Turn off and turn on the module in the phone settings.

If the scales are still not displayed:

1. Remove the scales from the list of associated devices (Settings → Bluetooth → Forget the device).
2. Reinstall the Mi Fit/Zepp Life app.
3. Try connecting from another phone – if the problem persists, the scales are faulty.

Problem 2: Data is not stored in the application

A common mistake is that the scales show the weight on the screen, but the data is not transmitted to the phone.

• 📵 Unstable Internet connection (data synced through the cloud).
• 👤 Incorrectly specified profile (height, age, gender) - because of this, the application can ignore the data.
• 🔄 Older version of the app (update it to Google) Play/App Store).

Decision:

1. Open the app and manually update the data (Profile → Devices → Sync).
2. Check that the phone settings allow background access for the application.
3. If you are using Mi Fit, try transferring data to Zepp Life (there is a “Data Transfer” option in your account settings).

Problem 3: Libra shows an error of "Err" or "Lo"

Errors on the scale screen usually mean:

• Err - overload (maximum weight exceeded) or unstable surface.
• Lo - batteries are discharged (replace them with new AAAs).
• --- — No weights are calibrated (step on them and come down, then repeat the weighing).

How to Transfer Data from Mi Fit to Zepp Life

If you've been using Mi Fit, but you've switched to Zepp Life, you can transfer the data without loss.

1. Open Mi Fit and go to Profile → Settings → Xiaomi Account.
2. Click on “Data Export” and select Zepp Life from the list of apps.
3. Confirm the transfer – the process may take several minutes.
4. Once completed, open Zepp Life and update the data (Profile → Sync).

Please note:

• 📅 Only data for the last year are transferred.
• 👥 If you have multiple profiles in Mi Fit, you will have to transfer each one separately.
• 🔄 After the transfer, you can delete Mi Fit – all data will remain in Zepp Life.

⚠️ Note: If you used Mi Fit with a Google Fit account, you will have to reconnect the export to Google Fit after transferring to Zepp Life (in the integration settings).

How to connect Xiaomi scales to multiple phones

One Xiaomi device can be synced with multiple smartphones (like yours and the trainer’s phone).

1. On the first phone, open Zepp Life/Mi Fit and go to Profile → Devices → Settings → Sharing.
2. Select the option “Add user” and generate QR-code or invitation.
3. On the second phone, install the same app, log in and accept the invitation.

Limitations:

• 📱 Maximum - 5 connected devices.
• 🔒 All users will see the same data.
• 📊 To separate the progress, each user needs to create a profile in the application.

If you need to share data (for example, for family members), it is better to buy separate scales or use one account in turn.

💡

To accurately analyze body composition, each weight user needs to create a separate profile in the app, showing height, age and gender.

Tips for using Xiaomi smart scales

To ensure that the data is as accurate as possible, follow these guidelines:

• ⏰ Weigh yourself at the same time (better on an empty stomach in the morning).
• 🚿 Do this before breakfast and after going to the toilet.
• 👕 Weigh yourself without clothes or in light clothing (the weight of clothes can be subtracted from the app settings).
• 📱 Put the scales on a hard surface (tile, laminate) - carpet or soft floor distort the readings.
• 🔋 Change batteries every 6 to 12 months (even if the scales work).

For dynamic analysis:

• 📊 Use the in-app charts – they show changes in weight, fat and muscle over the week/month.
• 🎯 Set realistic goals (e.g., lose 0.5–1 kg per week).
• 🍎 Sync data with Google Fit or Apple Health for comprehensive health analysis.

If you are exercising, pay attention to the “muscle mass” parameter – its growth as you gain weight may mean a set of muscles, not fat.
