Xiaomi scales: how to connect to the phone in 5 minutes - instructions with pictures and tips

Why sync Xiaomi scales with your phone and what it gives

Xiaomi's smart scales are not just a weight measurement device; they analyze body composition (fat, muscle, water percentage), track changes, and integrate with fitness applications. But all of these features are only available when you connect to a smartphone. Without synchronization, you get a normal mechanical scale with a digital display — and lose up to 80% of the device's capabilities.

It takes no more than 5 minutes to connect, but many users face typical problems: scales are not in the application, data is not saved, or the connection is constantly broken. In this article, we will discuss all the ways of synchronization (via Mi Fit, Zepp Life and even without official applications), and give tips for correcting errors. The instructions are relevant for all models, from the budget Mi Smart Scale 2 to the premium Xiaomi Smart Scale 3.

Importantly, if you use Xiaomi scales with iPhones, the connection process will be slightly different from Android devices.

What Xiaomi scales support phone connection

Not all Xiaomi smart scales can sync with a smartphone, here’s the full list of supported devices for 2026:

• 🔹 Xiaomi Mi Smart Scale 2 is the most popular model with analysis of 10 body parameters.
• 🔹 Xiaomi Smart Scale 3 – improved version with accurate sensor and support for Apple Health.
• 🔹 Xiaomi Mi Body Composition Scale 2 – premium model with advanced diagnostics (including bone mass).
• 🔹 Redmi Smart Scale – budget version with basic features.
• 🔹 Xiaomi Mi Scale (first generation) – outdated model, but still supported.

If your model is not on this list, check its name on the box or in the documentation. OEM-Version for other brands will not synchronize.

What you need to connect: full checklist

Before you start synchronizing, prepare everything you need. Here's the minimum set:

Install Mi Fit or Zepp Life (links below)

Turn on Bluetooth on your phone

Charge the scales (if they are discharged, the indicator will not light up)

Connect your phone to Wi-Fi or mobile internet (need to download data)

Create a Xiaomi account (if you don’t already have one)

-->

If you are using an iPhone, check out:

• 📱 iOS version is at least 13.0 (for Mi Fit) or 14.0 (for Zepp Life).
• 🔄 In your phone settings, allow the app to access Bluetooth and Notifications.
• 🌐 Xiaomi account region must match the App Store region (otherwise, the application may not find the scales).

Attention! If you've used a scale with another phone before, you'll need to reset it to factory settings, press and hold the switch on (if you have one) or place the scale on a flat surface and step on it, holding the weight for 10 seconds, so the reset should work.

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

Consider a generic way through the Mi Fit app (works for 90% of models). If you have a Smart Scale 3 or newer, it's better to use Zepp Life - the instructions for it will be lower.

Step 1: Installation and configuration of the application

1. Download Mi Fit from the official store:

• 🤖 Google Play for Android
• 🍎 App Store for iPhone

2. Launch the app and sign in to your Xiaomi account (or sign up if you don’t).

3. Click on the profile icon in the upper right corner → Add the device → select Libra.

Step 2: Activation of the scales

1.Put the scales on a flat, hard surface (not on a carpet!).

2 Step on the scales - the display should appear 0.0 or flashing indicator.

3. Take off your leg: the scales will go into standby mode and start looking for the phone.

Step 3: Synchronize with your phone

1.In the Mi Fit app, select your weight model from the list.

2. wait for the phone to find the device (it can take up to 30 seconds).

3. Confirm the connection - the balance should flash a tick or the message OK.

Now, the data will automatically sync with each weigh.

💡

If the scales are not, try rebooting Bluetooth on your phone: turn it off and turn it on again in the settings.

Connect via Zepp Life (for Smart Scale 3 and later)

For Smart Scale 3 and Mi Body Composition Scale 2, the Zepp Life app (formerly the Mi Fit for premium devices) is the same process, but with minor differences:

1. Download Zepp Life (Android/IOS)
2. Log in to the same Xiaomi account as Mi Fit (data synced between apps).
3. In the Devices section, click + → Libra → select the model.
4. Step on the scales and wait for the connection.

Importantly, if you've used Mi Fit before, the data will automatically be transferred to Zepp Life after you first log in.

Typical Connection Errors and How to Fix Them

If Xiaomi scales are not connected to the phone, check the following points:

Mistake 1: Libras are not in the appendix

• 🔋 Battery discharge: Replace the batteries (usually 4)×AAA).
• 📶 Weak Bluetooth signal: Bring the phone closer to the scales (maximum 10 meters).
• 🔄 Conflict with other devices: disconnect from the phone other gadgets (headphones, fitness bracelets).
• 📱 Outdated firmware: update the Mi app Fit/Zepp Life to the latest version.

Error 2: Data is not saved or reset

If after weighing in the application no new records appear:

1. Check that the profile shows the correct height and gender - without this, the calculations will be incorrect.
2. Make sure your phone is connected to the internet (the data is synced to the cloud).
3. Restart the app: Close it in the multitasking menu and reopen it.

Mistake 3: Libra shows an "Err" error

The Err or E code on the scale display means:

• 🔋 Low battery charge (replace the batteries).
• ⚖️ Unstable surface (put scales on a hard floor, not on a carpet).
• 🧍 Weight limit exceeded (maximum for most models – 150 kg).
• 🔧 Sensor failure (if the error appears constantly, contact the service).

⚠️ Warning: If you see an error E2 or E3, This indicates a hardware malfunction, and you can't fix it yourself, you need to repair or replace the sensor.

How to set up multiple profiles on a single scale

One of the key benefits of Xiaomi's smart scales is that it supports multiple users, and it's family friendly, and everyone will only see their data in the app. Here's how to add additional profiles:

1. Open Mi Fit or Zepp Life and go to Profile.
2. Click Add Family Member or Manage Profiles.
3. Enter the new user’s information: name, height, gender, age.
4. Save the profile. Now, when weighing, the scales will automatically recognize the user by weight (with an accuracy of ±2 kg).

Important: for accurate recognition, each user must weigh at least 3 times, so the algorithm will remember its parameters. If the weight of two people differs by less than 5 kg, identification errors may occur.

To remove the profile:

1. Go to Settings. → Profile management.
2. Select an unnecessary profile and click Delete.
3. Confirm the action. This user's data will be deleted from the history.

💡

Xiaomi scales can store up to 16 profiles in Mi Fit and up to 20 in Zepp Life. If the limit is reached, delete unused accounts.
