Why Your Xiaomi Libras Are Not Connecting to Your Phone – and How to Fix It

Xiaomi’s smart scales (including the Mi Body Composition Scale 2, Smart Scale 2 and Xiaomi Scale 3) should sync with the phone in 30 seconds — but in practice, users face connection errors, a communication interruption or a lack of data in the application. 80% of the time is not due to a device failure, but to the wrong sequence of actions or missed settings of the smartphone.

In this article, the current 2026 manual for the pairing of Xiaomi scales with Android and iPhone, including solving typical problems from the lack of reaction to the weighing to the error "Device not found." We tested the process on 5 models of scales and 3 versions of phone firmware - all the steps are tested in practice.

If you’ve already tried to connect and you’ve got an error, don’t reset the scales to factory settings (this will remove the measurement history). Instead, scroll through to the “What to do if the scales aren’t connected” section, where all the working ways to restore communication are collected.

What scales Xiaomi maintain communication with the smartphone

Not all Xiaomi smart scales can sync with the phone, here’s the full list of supported models (as of 2026):

• 📱 Xiaomi Mi Body Composition Scale 2 is the most popular model with analysis of body composition (muscle mass, water, bone tissue).
• 📱 Xiaomi Smart Scale 2 – budget version without body composition analysis, only weight.
• 📱 Xiaomi Scale 3 – updated version with improved sensors and support for Bluetooth 5.0.
• 📱 Xiaomi Mi Smart Scale (first generation) is an outdated model, but still works with new versions of applications.
• 📱 Xiaomi Mi Body Fat Scale – a specialized model for measuring fat mass.

Xiaomi scales do not require recharging - they work from batteries of the type AAA (4 pieces, which lasts 12-18 months with daily use. If the indicator on the scales does not light up when pressed, first check the batteries.

What applications are needed to connect

To synchronize the scales Xiaomi phone requires one of the official applications, the choice depends on the model of the scales and the region of purchase:

Since 2023, Xiaomi has been actively moving users from Mi Fit to Zepp Life. If you have an old application installed, the system will offer to update. Don't refuse to update - Mi Fit has stopped adding support for new devices.

⚠️ Note: If you use an iPhone, make sure that the Bluetooth settings include "Allow applications to connect to Bluetooth." On Android 12+ Check the permission for the "Exact Location" for the application - without it, there will be no scales.

Step-by-step: how to link the scales with the phone

The connection process takes only 2-3 minutes, if you follow the exact sequence, and we break it down into stages, taking into account the features of Android and iOS.

Preparation of scales and telephone

Before connection:

Install batteries in the scales (4).×AAA)

Turn on Bluetooth on your phone

Download the Zepp Life or Mi Fit app

Register an account in the application (email or phone)

Put the scales on a flat, hard surface.-->

If the batteries are installed correctly, the indicator (white or blue LED) should light up briefly when pressing the scales. If the indicator does not burn, check the polarity of the batteries or replace them.

Addition of a device in the annex

Open the Zepp Life app (or Mi Fit) and follow the following steps:

1. Click on the + icon (add device) in the upper right corner.
2. Select the Libra category.
3. Find your model in the list (for example, Mi Body Composition Scale 2).
4. Click "Connect" and follow the instructions on the screen.

At the connection stage, the app will ask you to stand on the scale. Don't stand on them in advance - wait for the commands in the application, otherwise the synchronization may be interrupted.

First weighing and calibration

When the app finds the scales, perform the first weighing:

• 👣 Stand on the scales with bare feet (socks distort the readings of body composition sensors).
• 📱 Wait until your weight appears on the scale screen (usually 3-5 seconds).
• 🔄 The data will be automatically sent to the application. If this does not happen, check the Internet connection (data synced through the cloud).

After the first successful weighing, the scales will automatically recognize you by weight (with a margin of error). ±If there are several users in the house, each needs to go through the connection procedure separately.

💡

If the scales show weight but the data doesn’t appear in the app, restart Bluetooth on your phone and repeat the weigh.
