Why Xiaomi Libras Don’t Connect First Time and How to Fix It
Xiaomi’s smart scales are some of the most popular gadgets for weight and body composition, but their first connection is often questionable. Even experienced users can have difficulties: the app does not see the device, the scales do not turn on or show an E2 error. The reason usually lies in three things: improper smartphone preparation, outdated firmware of the scales or conflict with other Bluetooth devices.
In this article, we’ll cover all the current connectivity options for the Mi Body Composition Scale 2, Mi Smart Scale 2, Xiaomi Smart Scale and others, including solutions to common bugs. You’ll learn how to sync scales with Android and iPhone, update firmware and set up automatic data transfer in Mi Fit or Zepp Life. And if you’ve already had connection issues, there’s a fault diagnosis section at the end of this article.
What Xiaomi scale models support connection to a smartphone
Not all Xiaomi scales are equipped with a Bluetooth module for syncing with the phone. Here is the current list of models that can be connected to the application:
- 🔹 Xiaomi Mi Body Composition Scale 2 - flagship model with an analysis of 13 body parameters (muscle mass, bone tissue, water, etc.).
- 🔹 Xiaomi Mi Smart Scale 2 – a simplified version with basic metrics (weight, BMI, fat mass).
- 🔹 Xiaomi Smart Scale (first generation) – supports only weight and BMI, but still works with Mi Fit.
- 🔹 Xiaomi Mi Body Fat Scale – a specialized model for measuring fat mass.
Important: Libras without Bluetooth (such as the mechanical Xiaomi Mi Basic Scale) cannot transmit data to the phone. They can only be used for local weighing.
Preparing for connection: what to do before synchronization
Before you connect the scales, follow 4 mandatory steps to avoid errors:
- Update the app. Install the latest version of Mi Fit (for the first time) Android/iOS) or Zepp Life (if you have a new scale model: 📱 Mi Fit for Android 🍎 Mi Fit for iOS
Turn on Bluetooth.
Mi Fit
Charge the scales.
AAA
Make sure the scales are not connected to another device
A critical mistake many users make: trying to connect via the Bluetooth settings of the phone instead of the Mi Fit app. Xiaomi scales are not displayed in the list of available devices in the standard way - they can only be added through proprietary software.
☑️ Preparation for connection
Step-by-step: how to connect Xiaomi scales to the phone
Consider a universal algorithm for all supported models. The instructions are relevant for Android 10+ and iOS 14+:
Step 1: Starting the pairing process
1. Open the Mi Fit or Zepp Life app and log in (use the same account as other Xiaomi devices).
2. Go to Profile → Add the device.
3. Select the Libra category and model of your device.
Step 2: Activation of the scales
1. Stand on the scales with bare feet (socks or slippers distort the readings of body composition sensors).
2. wait until the weight value appears on the scale screen (usually this takes 3-5 seconds).
3. Go back to the app, it should automatically detect the scales. If it didn't, click Can't find it? Try it manually.
Step 3: Completion of the setup
1. Confirm the connection in the application (click Hide).
2 Enter your gender, age, height and activity level to correctly calculate BMI and other metrics.
3. Wait for synchronization - the scales will send the test data to the application.
If it goes well, your scale model will appear in the Devices section, and now, every time you weigh it, it will automatically be transmitted to your phone.
💡
If the scales do not respond to pressing, try resetting them to factory settings: press the on button for 15 seconds until the indicator blinks 3 times.
Comparison of Connection Methods: Mi Fit vs Zepp Life
From 2023, Xiaomi will gradually move its devices from Mi Fit to Zepp Life (formerly known as Amazfit).
| Criteria | Mi Fit | Zepp Life |
|---|---|---|
| Supported weight models | All, including the old ones (Smart Scale 1) | The newest (Mi Body Composition Scale 2 and later) |
| Synchronization with other devices | Yeah (bracelets, watches) | Yes, but better integrated with the Zepp ecosystem |
| Data analytics | Basic (weight charts, BMI) | Extended (trends, nutrition tips) |
| Export of data | Google Fit, Apple Health | Google Fit, Apple Health, Strava |
Recommendation: If you have a new scale model (released after 2022), use Zepp Life - there is more functionality and stable work with Bluetooth 5.0. For old scales (Smart Scale 1), stay on Mi Fit.

Typical Connection Errors and Their Solutions
If the scales are not connected, check the following points:
- 🔋 Libras not turned on: Check the batteries (even new ones can be discharged); Clean the contacts of the battery compartment with a cotton swab dipped in alcohol; if the indicator flashes red, the scales are discharged (replace the batteries).
- 📱 Phone doesn't see scales: Turn off VPN And antivirus -- they can block Bluetooth connection. Reset your smartphone and scales (remove the batteries for 30 seconds). Make sure the distance between the devices is no more than 1 meter.
- ⚙️ Mistake. E2 or E3: E2 — overload (maximum weight for most models – 150 kg). E3 — unstable position (stand on the scales evenly, without movement).
⚠️ Note: If the scales show an error E1, This means that the sensors are malfunctioning, and in this case, only the service center will help, and self-repair will lead to the loss of warranty.
If neither of these methods worked, try connecting the scales to another phone. If the problem persists, contact Xiaomi with a photo of the check and the serial number (located at the bottom of the scale).
💡
90 percent of connectivity problems are solved by replacing batteries or restarting your smartphone. Start diagnosing with these steps.
How to update the firmware of Xiaomi scales
Outdated firmware can cause synchronization errors or incorrect readings.
- Open Mi Fit or Zepp Life and go to your scales section.
- Slap the icon. ⚙️ Settings of the device.
- Select firmware update (if the item is missing, you have the latest version).
- Confirm the download and wait until the process is completed (don’t interrupt!).
Important: During the upgrade, the scales should be on and be next to the smartphone. If the process is interrupted, you may need to reset the settings.
The latest firmware version for Mi Body Composition Scale 2 can be checked on the official Xiaomi website (Support section).
Additional settings: how to set up automatic synchronization
To automatically save data from the scales to Google Fit or Apple Health:
- In Mi Fit/Zepp Life, go to Profile → Settings → Data Synchronization.
- Choose the service you want (Google Fit, Apple Health, or Strava).
- Log in and allow access to data on weight and body composition.
- Set the synchronization frequency (recommended automatically).
Now, with each weighing, the data will be duplicated into the selected application, which is convenient if you use multiple fitness trackers.
Tip: In the weight settings, you can turn on the Progress Notice option. The app will send weekly reports with changes in weight and recommendations.
