How to connect Xiaomi Mi Smart Scale 2 to your phone: full instructions with photos and tips

The Xiaomi Mi Smart Scale 2 is not just a weight-measuring device, it's a full-fledged health-tracking tool. It analyzes 13 key body metrics, including fat percentage, muscle mass, and water level. But to access all of this data, you first have to connect the scales to your smartphone correctly. Many users have difficulty at this point: the app doesn't see the device, the sync is interrupted, the data is not stored.

In this article, we will look at all the ways Mi Smart Scale 2 connects to Android and iOS phones, including solving common bugs: you will learn which app is best to use (Mi Fit or Zepp Life), how to reset the scales to factory, and what to do if the device is not determined, and also a unique life hack to accelerate sync via Bluetooth 5.0, which is not in the official instructions.

What apps support Xiaomi Mi Smart Scale 2

The Mi Smart Scale 2 is compatible with two official Xiaomi apps:

• 📱 Mi Fit is a classic application for all fitness trackers and smart devices of the brand. supports Russian, but has limited data analysis functions.
• 🌐 Zepp Life (formerly Mi Fit in some regions) is an updated version with advanced analytics, integration with Google Fit and Apple Health.

Both apps are available for Android 5.0+ and iOS 10.0+. The main difference is that Zepp Life can automatically sync with other services (such as Strava or MyFitnessPal), while Mi Fit requires manual data export.

Important: If you’ve used Mi Fit before, the data history will not be automatically transferred to Zepp Life, but you’ll have to manually export it through Profile → Settings → Data Export.

Preparation of scales and phone before connection

Before you start pairing, make sure that all the prerequisites are met:

Replace the batteries (4×AAA) or charge the scales (if the model has a battery)

Turn on Bluetooth on your phone

Install one of the applications (Mi Fit or Zepp Life)

Place the scales on a flat, solid surface (not on the carpet!)

Make sure the distance between the phone and the weight is no more than 10 meters.-->

Pay special attention to batteries. The Mi Smart Scale 2 doesn't turn on when the batteries are discharged, but it doesn't show a discharge indication (unlike the newer models). If the scales don't respond to pressing, try replacing the batteries with new ones - even if they look like they're working.

Also check the app permissions. On Android, go to Settings → Apps → Mi Fit/Zepp Life → Permissions and turn on:

• 📍 Geodata (required for correct calculation of body mass index)
• 📱 Bluetooth (required for connection)
• 📁 Warehouse (for data export)

⚠️ Warning: If you use an iPhone, turn off Battery Savings mode in Settings before connecting → Battery: In this mode, iOS restricts background Bluetooth operation, which can interrupt synchronization.

How to connect Mi Smart Scale 2 via Mi Fit

If you have chosen the Mi Fit app, follow this instruction:

1. Open Mi Fit and log in (or sign up if you don’t have an account) and use the same account as you use on other Xiaomi devices (like your smartphone or fitness bracelet) to keep your data synced.
2. Click on the profile icon (in the lower right corner) and select Add Device.
3. In the list of devices, find Libra and select the Mi Smart Scale 2 model.
4. Press "Connect" and follow the cues on the screen. The scales should flash blue light, which means they're ready to pair.
5. Stand on the scale (with bare feet, evenly spreading the weight), the data will be automatically transmitted to the application.

If you have a “Can’t Find the Device” error at the connection stage, try:

• 🔄 Reboot Bluetooth on your phone (disable and turn on again).
• 📵 Remove the scales from the list of conjugate devices in the Bluetooth settings of the phone and reconnect.
• 🔋 Replace batteries in scales – even if they are new, sometimes contact is broken.

💡

If the scales do not flash blue when connecting, press them once with your foot - this forcibly activates the pairing mode.

Connecting with Zepp Life: Differences and Benefits

The connection process in Zepp Life is similar, but there are a few key differences:

To connect scales through Zepp Life:

1. Open the app and go to the Devices section (the + icon in the upper right corner).
2. Choose Libra → Mi Smart Scale 2.
3. Click Connect and wait until the scales flash white (unlike the blue in Mi Fit).
4. Stand on the scales – the data is synchronized automatically.

Zepp Life has a unique Smart Goals feature that analyzes your performance and offers personalized nutrition and exercise recommendations, for example, if the scales record a high percentage of visceral fat, the app will offer an action plan to reduce it.

⚠️ Note: If you have previously connected scales via Mi Fit, remove them from both apps before switching to Zepp Life and reset (press the button on the back of the scales for 5 seconds until the indicator flashes.

Solving problems: Scales do not connect or transmit data

If the Mi Smart Scale 2 is not determined by the phone or data is not saved, check the following points:

• 🔌 Powering the scales: Make sure the batteries are inserted correctly (observe polarity!).If the scales aren't turned on, try cleaning the battery compartment contacts with a cotton swab soaked in alcohol.
• 📶 Bluetooth interference: Disable other Bluetooth devices (earphones, fitness bracelets) and make sure there are no interference sources nearby (microwaves, 2.4GHz Wi-Fi routers).
• 📱 App version: Update Mi Fit or Zepp Life to the latest version.Older versions may not support new Bluetooth protocols.
• 🔄 Reset the scale: Press the button on the back of the scale for 10 seconds until the indicator flashes red.

If the problem persists, try an alternative way to connect:

1. Open Bluetooth settings on your phone.
2. Find the device in the list MI_SCALE (even if it's not connected).
3. Click on it and select Forget the device.
4. Restart the phone and reconnect through the app.

How to set up multiple profiles on a single scale

One of the key benefits of the Mi Smart Scale 2 is that it supports multiplayer, automatically recognizing different people by weight (with an error of ±3 kg) and storing the data in the appropriate profiles to customize multiple users:

1. Open the app (Mi Fit or Zepp Life) and go to Profile → User Management.
2. Click Add User and enter data (gender, age, height).
3. Ask the second user to stand on the scale. The app will suggest linking the measurement to a new profile.

Maximum number of profiles:

• 👨‍👩‍👧‍👦 Mi Fit: Up to 16 users.
• 👨‍👩‍👧‍👦‍👧 Zepp Life has up to 20 users.

If the scales confuse users (for example, if the weight of two people is close), perform manual binding:

1. Stand on the scale.
2. The app will show a notification “New Dimension” – click on it.
3. Select the desired profile from the list or create a new one.

⚠️ Warning: If you have a pregnant woman in your family, turn off the "By body composition analysis" option in your weight settings for your profile. In this mode, Mi Smart Scale 2 uses bioimpedance analysis, which is not recommended during pregnancy.

Update firmware and reset settings

Regular firmware updates improve measurement accuracy and add new features to update Mi Smart Scale 2:

1. Open Zepp Life (in Mi Fit updates come less frequently).
2. Go to Profile → Mi Smart Scale 2 → Device settings.
3. If an update is available, the “Update” button will appear – click it.
4. Wait until the process is complete (the scales should flash green). Don't move away from the scales and turn off Bluetooth!

If after the update the scales started to work incorrectly (for example, do not turn on or show an error "E1"), perform a hard reset:

1. Turn the scales over and find the reset button (a small hole next to the battery compartment).
2. Insert a paperclip into the hole and hold the button for 15 seconds until the indicator flashes red 3 times.
3. Connect the scales again through the app.

If the scales don't turn on after you've dropped them, check the contacts of the batteries -- sometimes they oxidize. Rub them with a blower or alcohol.
