The Xiaomi Mi Smart Scale 2 is not just a weight measurement device, it's a full-fledged health control assistant. It analyzes 13 key parameters of the body, including muscle mass, fat level and even bone density. But to access all this data, the scales need to be connected correctly to the smartphone. Many users face difficulties at this stage: the application does not see the device, the data does not sync. In this article, we will analyze all the ways of connecting, including solving typical problems, and give practical tips for setting up.
It's important to understand that the connection process depends on the scale model and the firmware version. For example, for Mi Body Composition Scale 2 and Xiaomi Smart Scale 2, the algorithm will be the same, but the names of menu items in the application may differ. We'll look at the universal method that works for most Mi Smart Scale devices, and also point out the nuances for specific models. If you just unpacked the scales or decided to reconfigure them after reset, this instruction will help you do everything quickly and without errors.
What applications are needed to connect Xiaomi smart scales
Xiaomi’s scales require an official application that will collect and analyze data, and there are two main options available today:
- 📱 Mi Fit is a classic application from Xiaomi, supports most of the ecosystem’s devices, including scales, fitness bracelets and treadmills. It has a Russian interface and integration with Google Fit and Apple Health.
- 🌐 Zepp Life (formerly Amazfit) is an updated version from the same developer, with a more modern design and advanced health analysis features.
If you already have Mi Fit installed and everything is stable, it doesn't make sense to switch to Zepp Life, but the new app offers more detailed statistics and convenient reports, both free and available for Android and iOS.
Important: some users mistakenly try to connect scales through Mi Home (smart home app). This is wrong - Mi Home is not designed to work with wearable devices and weights. Use only Mi Fit or Zepp Life.
Step-by-step: how to connect the scales Xiaomi Mi to the phone
The connection process takes no more than 5 minutes, if you follow a clear algorithm, and we will analyze it using the Mi Fit application (for Zepp Life, the steps are similar, only the names of some items differ).
- Install the app: Download Mi Fit from Google Play or App Store. After installation, sign up or sign in via your Xiaomi, Google or Apple ID account.
- Turn on Bluetooth on your phone: Libra connects to your phone via Bluetooth Low Energy (BLE), so make sure it's activated.It's also recommended to turn off the power saving mode for the Mi Fit app in the phone's settings.
- Prepare the scales for pairing: Remove the protective film from the battery compartment (if any) and install 4 AAA batteries. The scales will automatically turn on. Wait until 0.0 appears on the display, which means the device is ready to connect.
- Add scales in the app: Open Mi Fit, go to Profile → Add Device → Libra. Select your model (e.g. Mi Smart Scale 2) and click Connect.
- Synchronize the data: Stand on the scale, the phone's interface request will appear on the display, confirm it, and in a few seconds the data will sync.

If the scales don't connect the first time, don't panic. In the next section, we'll look at common mistakes and their solutions.
Xiaomi Libra does not connect to the phone: reasons and solutions
Even if you do the instructions correctly, you can have problems, and here are the most common scenarios and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| Phone can't see scales | Bluetooth is disabled or scales are not in pairing mode | Turn on Bluetooth, reboot the scales (remove and insert the batteries) |
| The application freezes at the connection stage | Older version of Mi Fit or Zepp Life | Update the app in the app store |
| Data is not synchronized | Libra connected to another phone | Reset the scales to factory settings (hold the 10 seconds switch) |
| Libra shows E1 or E2 error | Unstable nutrition or overload | Check the batteries, stand on the scale without shoes |
Critical information: if the scales give off an E3 error, it means a calibration failure. The solution is to reset (hold the 15-second button) and reconnect.
⚠️ Note: If you use an iPhone, make sure that the privacy settings are in place. → Geolocation services for Mi Fit application set to When in use. Without this, the Bluetooth connection may not work stable.
If neither of these methods worked, try connecting the scales via another phone (like Android if you have an iPhone, or vice versa) to help determine if there is a problem with the scales or your smartphone.
How to Reconfigure Xiaomi Scales to a New Phone
When changing your phone or resetting your weight settings, you'll need to reconnect.
- Remove the scales from your old phone: Open Mi Fit, go to Profile → My devices, select scales and click Remove.
- Reset the scales to factory settings: Remove the batteries for 30 seconds or hold the power button for 10-15 seconds until 0.0 appears on the display.
- Connect to a new phone: Repeat the steps from the step-by-step instructions above.
Important: When you transfer data to a new phone, your measurement history is not automatically saved. To avoid losing statistics, export the data to Google Fit or Apple Health before removing the scales from your old phone.
💡
If you use the same Xiaomi account on both phones, your measurement history syncs automatically after you reconnect the scales.
How to update the firmware of Xiaomi smart scales
The firmware of the scales is automatically updated via the Mi Fit or Zepp Life app, but sometimes you need a manual update.
- Open the app and go to the section with your weights.
- If an update is available, a notification will appear New firmware is available. Click Update.
- Wait for the process to be completed (the scales should be on and be near the phone).
It takes 2-5 minutes to update, and don't interrupt or turn off Bluetooth.
⚠️ Warning: If the scales go off during the upgrade (e.g., the batteries go down), they may stop reacting to the switch on. In this case, remove the batteries for 1 minute, then try again.

Tips for using Xiaomi smart scales
To ensure that the data is as accurate as possible, follow these guidelines:
- ⏰ Weigh yourself in the morning on an empty stomach - this will give the most stable results.
- 👟 Stand on the scales without shoes and socks, spreading the weight evenly.
- 📊 To analyze the dynamics, use weekly reports in the application.
- 🔋 Change batteries every 6-12 months (depending on the frequency of use).
If you're exercising, look at your muscle mass score, which will help you track progress better than just your weight, and use the Body Composition Analysis feature in the app to control your body fat.
💡
To accurately measure body composition (fat, muscle, water), Xiaomi scales use a bioimpedance analysis method. It works only with bare feet - socks or tights will distort the results.
