Xiaomi's smart scales are not just a weight measurement device, they're a full-fledged health tracking assistant. They analyze body composition, sync data with a mobile app, and even integrate with Apple Health or Google Fit. But to make all these functions work, you need to connect the device correctly to your smartphone. In this article, the guide is up to date for 2026, taking into account the latest updates to the Mi Fit and Zepp Life apps, as well as solving typical synchronization problems.
Many users have difficulty in the first connection phase: the scales are not in the application, the data is not stored, or the gadget does not respond to clicks at all, most often due to incompatibility of software versions, incorrect Bluetooth settings or trivial battery discharge, we will examine each step in detail, from unpacking the device to setting up notifications about progress.
What Xiaomi scales support connection to the application
Not all Xiaomi smart scales work with mobile apps, here’s a current list of supported devices (as of 2026):
- 📱 Mi Smart Scale 2 is the most popular model with an analysis of 13 body parameters (weight, BMI, muscle mass, etc.).
- 🔋 Mi Body Composition Scale 2 – improved version with increased accuracy and Wi-Fi support for synchronization without a smartphone.
- 💡 Xiaomi Smart Scale 3 - budget option with basic functions (weight, BMI, fat mass).
- ⚡ Mi Smart Scale S1 — model USB-C for charging and advanced analytics (water level, bone mass).
If your model is not included in this list, check its name on the official Xiaomi website or in the documentation. Outdated versions (for example, Mi Smart Scale 1) may not support the latest versions of Mi Fit or Zepp Life applications. Also note that some scales (for example, Xiaomi Mi Scale Lite) work only with Chinese versions of the software and require additional manipulation to connect.
What application is needed to connect
Until 2023, all Xiaomi smart devices were connected via the Mi Fit app, but after the rebranding of the Mi Ecosystem ecosystem into Zepp Life, that changed.
| Annex | Supported weight models | Features |
|---|---|---|
| Mi Fit | All models up to 2022 (Mi Smart Scale 2, Mi Body Composition Scale) | Simple interface, integration with Google Fit and Apple Health |
| Zepp Life | All models, including new ones (Smart Scale 3, S1) | Advanced analytics, Wi-Fi support, sync with Zepp (formerly Amazfit) |
| Xiaomi Wear (China) | Only for the Chinese market | Requires Chinese account Mi, unstable work outside China |
For most users in Russia and Europe, Zepp Life is the best choice. This app is actively developing, has a Russian-language interface and supports all current scale models. Mi Fit is still in the app stores, but updates for it are less common. If you have already used Mi Fit, the data will automatically be transferred to Zepp Life on the first sign-in under the same account.
⚠️ Note: Do not install applications from third-party sources (e.g, APK-This can lead to data leakage or incorrect balances. Use only official versions from the App Store or Google Play.
Preparation of scales and smartphone to connect
Before you start synchronization, make sure that all the prerequisites are met:
Install the Zepp Life or Mi Fit app
Turn on Bluetooth on your smartphone
Charge the scales (if the model with a battery)
Remove the protective film from the sensors (on the underside)
Put the scales on a flat, hard surface-->
Pay special attention to the placement of the scales. They should stand on a smooth, hard surface (for example, tile or laminate), carpet, soft-backed linoleum or uneven floor can distort the readings of the sensors, and make sure that there are no foreign objects under the weights - even small dust or pile can affect the accuracy of measurements.
If your scale model is battery-operated (e.g. Mi Smart Scale 2), make sure that it is installed correctly. Some devices have non-standard contact polarity, check the instructions. For Smart Scale S1 models, plug them into charging for 2-3 hours before first use. The charging indicator (if any) should be green, which means that the battery is charged enough to work.
💡
If the scales don't turn on after the batteries are installed, try removing and re-inserting them, and sometimes the contacts oxidize during storage, and this helps restore the connection.
Step-by-step instructions for connecting
Now, to the synchronization process itself, the instructions are suitable for both applications (Mi Fit and Zepp Life), the differences are listed separately.
Step 1: Launching the application and logging in to your account
Open Zepp Life or Mi Fit and log in to your Xiaomi, Google, Apple ID or Zepp account. If you don't have an account, sign up for the app. Without authorization, your data won't be saved to the cloud.
Step 2: Adding a new device
In the main menu of the app, click on the + icon (usually in the upper right corner) and select Add Device. In the list, find your scale model. If there is none, select Other Device → Libra.
Step 3: Activation of the balance pairing mode
Stand on the scale with bare feet (socks or slippers distort readings), zeros or words should appear on the screen. --.--. Wait 5-10 seconds, the scales will automatically go into search mode. In some models, you need to press the scale screen once to start pairing.
Step 4: Connect via Bluetooth
In the application will be a request to connect to the device with the name of the view MI_SCALE_XXXX. Confirm the pairing, if requested. PIN-code in 0000 or leave the field empty.
Step 5: Set up a user profile
Once you've successfully connected, the app will ask you to enter your gender, age, height and weight target, which is the information you need to correctly calculate your BMI and other metrics, and if you've already filled out a profile, you can skip this step.
Step 6. Test weighing
Do the first weigh-in to check the scales. The data should automatically show up in the application. If this does not happen, update the page or restart the application.
What to do if the scales are not in the application?
Set up notifications and synchronize with other services
After a successful connection, it is recommended to configure additional functions to maximize the capabilities of the scales:
- 📲 Progress Notifications: Enable the option in the app settings to receive weekly reports on changes in weight and body composition.
- 🔄 Auto Sync: Allow the application to run in the background so that the data is updated automatically with each weigh-in.
- 🌐 Data Export: Connect integration with Google Fit, Apple Health or Samsung Health so all metrics are stored in one place.
- 👨👩👧👦 Multiplayer mode: Add profiles for family members – scales will automatically recognize the user by weight (with an error). ±2 kg).
To set up data export in Zepp Life, go to Profile → Settings → Linked accounts and select the service you want. In Mi Fit, this section is called Accounts and Security. Once connected, check that the data is actually being transferred - sometimes manual synchronization is required.
⚠️ Note: If you use an iPhone, update iOS to the latest version before setting up Apple Health integration. Older versions (below iOS 15) may have errors when exporting data on fat mass and muscle tone.
Common mistakes and their solution
Even with the right connection, users often face problems, and here are the most common ones and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| Libras not included | Batteries or batteries are discharged | Replace batteries or charge the device for 2-3 hours |
| Data is not stored in the annex | No internet or account problems | Check your network connection and re-enter your account |
| Libra shows Lo error | Weak battery charge | Connect to charging for 1-2 hours, even if the indicator does not burn |
| App doesn't see scales | Conflict with other Bluetooth devices | Turn off other gadgets (earphones, fitness bracelets) and repeat the search |
| The evidence is very different from the real | Libra stands on an uneven surface | Move to a solid flat surface and perform calibration |
If none of these things worked, try to lose weight to factory settings.
- Hold the button on the scales (or touch the screen) for 10 seconds.
- Wait until the CLR or RESET is displayed.
- Release the button and wait for the reboot (about 30 seconds).
- Repeat the connection process again.
💡
If the scales don't work after reset, check them on another smartphone to help determine if there's a problem with the scales or your phone.
