How to connect Xiaomi scales to the phone: full instructions with photos and error solutions

Why Xiaomi scales don't connect to the phone: the main reasons

Xiaomi's smart scales are not just a weight-measuring device, but a full-fledged fitness tracker that analyzes body composition, water levels, and even bone mass. But to get all this data on a smartphone, you need to properly synchronize your devices. About 30 percent of users experience problems when they first connect — the scales can't find the phone, the app can't see the device, or the data is not stored.

The main causes of failures:

📱 Mi Fit or Zepp Life has not been updated for more than 6 months.
🔋 Discharged battery – Xiaomi scales run from 4 batteries AAA, If the charge is below 20%, the connection becomes unstable.
📶 Bluetooth problems – power saving mode is turned on or Bluetooth 4.0 module is turned off+.
🔒 Restrictions of the OS - on Android 12+ or MIUI 13+ Location access permission is required to work with Bluetooth devices.

In this article, we will break down the step-by-step connection for all Xiaomi scale models (including the Mi Body Composition Scale 2, Smart Scale 2, and Mi Scale), and solve common errors. If your scales are already connected but the data is not synchronized, go straight to the section on synchronization problems.

What Xiaomi scales support phone connection

Not all Xiaomi smart scales can sync with a smartphone. Here is the current list of supported models (2026):

Model	Support for applications	Features	Price (compared to market)
Mi Body Composition Scale 2	Mi Fit, Zepp Life	13 body metrics, wireless charging (in some versions)	2 500 — 3 200 ₽
Xiaomi Smart Scale 2	Mi Fit, Zepp Life, Apple Health	Thin case, support for up to 4 users	1 800 — 2 400 ₽
Mi Scale (First version)	Only Mi Fit.	Without analysis of body composition, basic functionality	1 200 — 1 600 ₽
Xiaomi Mi Body Fat Scale	Mi Fit (outdated firmware)	Support terminated in 2022	800 — 1 200 ₽

If your model is not listed in the table, check its name on the box or under the weights – sometimes Xiaomi releases regional versions with other indices (for example, XMSH07HM for Smart Scale 2).

⚠️ Note: Xiaomi Mi Body Fat Scale (released until 2020) is not officially supported after the Mi Fit update to version 5.0.

Preparing for connection: what to do before synchronization

Before you start pairing, follow these steps:

Install batteries (4×AAA) in the scale

Download the Mi Fit or Zepp Life app from the official store

Turn on Bluetooth on your phone

Allow location access (for Android 12+)

Charging the phone at least 30%-->

Pay special attention to batteries:

🔋 Use only alkaline batteries (like Duracell or Energizer) cheap salt cells discharge quickly.
⚡ After installing the batteries, the scales should automatically turn on – you will see a flashing indicator 0.0 on the display.
🔄 If the indicator doesn't burn, flip the scales and press the reset button (usually hidden under the sticker).

Also check the firmware version of the scales.

Stand on the scales - your weight will be displayed on the display.
Wait 5 seconds and the firmware version (e.g. 1.2.7) will appear.
If the version is below 1.1.0, update the scales through the app (instructions in the section below).

💡

If the scale shows a Lo error, it means low battery power. Replace all 4 cells at once - even if some are still working.

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

Consider the process using the Mi Body Composition Scale 2 and the Zepp Life app (also relevant for Mi Fit).

Step 1: Installation and configuration of the application

1 Download Zepp Life (formerly Mi Fit) from Google Play or the App Store.

2. Sign up or sign in through your Xiaomi/Google/Apple account.

3. In the main menu, click Profile → Add device → Libra.

Step 2: Synchronize over Bluetooth

1. Turn on Bluetooth on your phone and place the scales on a flat surface (not on the carpet!).

2. Stand on the scales - your weight will appear on the display, followed by a Bluetooth icon (📶).

3.In the Zepp Life app, select your weight model from the list.

4. wait until the synchronization is completed (usually takes 10–30 seconds).

Step 3: Set up a user profile

After connecting, the application will suggest entering:

👤 Gender (male/female)
📏 Growth (in cm)
🎂 Age.
🏃‍♂️ Activity level (low/medium/high)

Important! This data affects the accuracy of the measurement of fat mass and muscle composition, and if you put the wrong height, the error can be as high as 10-15%.

💡

Xiaomi scales store the last 16 weigh-ins in their memory, but long-term analysis requires synchronization with the phone!

How to update the firmware of Xiaomi scales

If your scales are unstable or do not support new features (such as measuring blood viscosity in Mi Body Composition Scale 2), update your firmware:

Open Zepp Life and go to Profile → My devices. → [Your scales] → Settings (⚙️) → Firmware update.
If a new version is available, click Update.
Place the scales next to the phone (distance is not more than 1 meter) and wait for the process to be completed (3-5 minutes).

⚠️ Warning: Do not interrupt the update or remove the scales from a flat surface. If the process is interrupted, the device may stop turning on - you will need to reset through the Reset button (below the battery compartment).

After the update:

🔄 Reset the scales (take out and insert the batteries).
📱 Reconnect them in the app (Profile) → My devices. → Add the device).
📊 Check out the new metrics in the section Analysis of body composition.

Problem Solving: Scales are not connected or synchronized

If synchronization is not possible, use this instruction:

Problem.	Possible cause	Decision
Libra doesn't find the phone	Bluetooth is disabled or faulty	Turn on Bluetooth, restart your phone, check the module in Settings → Connections
App doesn't see scales	The Mi Fit/Zepp Life version is now available.	Update the app in the store or reinstall it
Data not stored	No access to the Internet or the cloud	Check Wi-Fi/mobile network connection and app permissions
E1 or E2 error	Sensor overload or unstable power supply	Replace batteries, put the scales on a hard surface

If nothing helps, reset the scales to the factory settings:

Turn the scales over and find the Reset button (may be hidden under the sticker).
Press it with a thin object (clip) and hold it for 5 seconds.
After resetting, reconnect the scales as when you first use them.

What to do if the scales show an E3 error?

E3 error means failure of the weight sensor. This can be caused by: - Falling of the scales from a height (damage to the strain gauge). - Moisture entering the housing. - Factory defect (rarely). Solution: 1. Wipe the contacts of the batteries with alcohol. 2. Check the scales on another flat surface. 3. If the error repeats, contact the service center (the Xiaomi scale guarantee is 12 months).

Set up notifications and integrate with other services

To automatically get your weight data to Google Fit, Apple Health, or Samsung Health, do the following:

Sync with Google Fit (Android)

Open Zepp Life and go to Profile → Settings → Accounts and Sync.
Select Google Fit and log in.
Allow access to data on body weight and composition.

Sync with Apple Health (iPhone)

On iOS, the process is a bit more complicated:

In Zepp Life, go to Profile → Settings → Apple Health.
Turn on the switches for Weight and Body Composition.
Open the Health app on your iPhone and check that the data appears in the Body → Weight section.

You can also set up weighing notifications:

📅 In Zepp Life, go to Profile → Settings → Notifications.
🔔 Enable the Weighdown Reminder option and select a time (e.g. every morning at 8:00 am).
📊 Include a weekly report to get a summary of weight changes.

FAQ: Frequent questions about Xiaomi weights

Can you connect Xiaomi scales to two phones at the same time?

Yes, but with limitations. Xiaomi scales support up to 16 users, but only Mi Body Composition Scale 2 and Smart Scale 2 models can sync with multiple phones at the same time. To do this: On the first phone, connect the scales using Zepp Life. On the second phone, log into the same Xiaomi account - the data will be synchronized automatically. If you use different accounts, each phone will only see its weighings.

How to reset the history of weighing in the application?

To delete all data: Open Zepp Life and go to Profile → My Devices → [Your Libra]. Click Delete Device (this will only remove the anchor, not the history). To completely reset the story, go to Profile → Settings → Delete the account (Warning: This will delete ALL data, including steps and sleep!). Partial deletion of individual records is impossible - this is a limitation of the Xiaomi server part.

Xiaomi scales show the wrong weight. How do you calibrate?

If the error is greater than ±0.3 kg, calibrate: Put the scales on a flat hard surface (like a tile). Stand on them and wait for a stable reading. If the weight is over/underestimate, reset the scales with the Reset button and re-weigh. If the problem persists, check the batteries - when the charge is low, the sensors work incorrectly.

Can I use Xiaomi scales without a phone?

Yes, but with limitations: 📊 Libra will show your weight and body mass index (BMI) on the display. 🚫 Without a phone, you won’t see a detailed analysis of body composition (fat, muscle, water). 📈 The data will not be stored in history (the scales only store the last 16 weighings.

How to transfer data from Xiaomi scales to a new phone?

If you have changed your smartphone, use one of the following methods: Method 1 (recommended): Install Zepp Life on a new phone and log in to the same Xiaomi account - all data are synchronized automatically. Method 2 (for iPhone): Restore iCloud backup if Apple Health sync is enabled. Method 3 (manual): Export the data to Google Fit, then import it to a new phone. If you forget the password from your Xiaomi account, restore it through the official website.
