Connecting Xiaomi Mi Smart Scale 2 smart scales to a smartphone: from unpacking to the first measurements

Why you need to synchronize the scales with the phone and what the application gives

The Xiaomi Mi Smart Scale 2 is not just a weight measurement device, but a full-fledged analytical tool that can track body weight change dynamics, body fat percentage, muscle mass, and even body water levels. But all of this functionality is only revealed when you connect to your smartphone correctly. Without synchronization, you will get a conventional electronic scale with a digital display — no history of measurements, graphs or recommendations.

Mi Fit (older versions) or Zepp Life (new Xiaomi 2026) are turning scales into part of the health ecosystem, automatically storing data, graphing progress, syncing with Google Fit or Apple Health, and allowing multiple users to create family profiles, for example, if you're tracking your weight with your spouse or child, you can have a separate account, the scales recognize the user by weight and show personal data.

But there's a big problem: many users are facing connectivity problems — the scales aren't on the phone, the app can't see the device, or the data isn't saved — most often due to Bluetooth misconfiguration, outdated firmware, or application version conflicts. In this article, we'll look at all the current ways to connect for 2026, including bypassing common errors and optimizing measurement accuracy.

What you need to connect: full checklist

Before you start syncing, make sure you have everything you need, and missing at least one item from the list can cause you to crash.

• 📱 Smartphone on Android 6.0+ or iOS 12.0+ Bluetooth 4.0 (or newer).
• 🔋 Smart scale Xiaomi Mi Smart Scale 2 with a battery charge of at least 20% (checked by the indicator when turned on).
• 🌐 Stable Internet connection (for downloading the application and updating the firmware of the scales).
• 📲 The Zepp Life app (recommended) or Mi Fit app (outdated but still working).
• 👤 Xiaomi or Zepp account (can be created directly in the app).

Pay special attention to the Bluetooth version. If your smartphone Released before 2015, it may not support Bluetooth Low Energy (BLE), which is necessary for the scales to work. Check this in the phone settings: go to Settings → About Phone → Software information and find the "Bluetooth" section.

⚠️ Note: If you have previously used weights with the Mi Fit app, export your data history before switching to Zepp Life. Otherwise, the statistics may be lost when you change your account.

Step-by-step: Connect via Zepp Life (current in 2026)

Since 2023, Xiaomi has officially moved all wearable devices to the Zepp Life platform, so this method is a priority.

1. Installation of the app: Download Zepp Life from Google Play or the App Store. Avoid third-party sources - this is fraught with viruses.
2. Account registration: Open the app, click Register and select a method (email, phone number or Xiaomi account). If you already have a Mi Fit account, use the same login data.
3. Adding device: On the home screen, tap the icon + (in the upper right corner) → Add device → Libra → Mi Smart Scale 2.
4. Bluetooth activation: The app will request access to geodata and Bluetooth — allow both requests. Then turn on Bluetooth on your phone and wait for the scales to appear in the list of available devices.
5. Synchronization: Stand on the scales (they should turn on automatically). The phone will request connection — confirm it. Libra will emit an audible signal and flash the indicator.
6. Profile setting: Specify your height, age, gender and goal (weight loss, weight gain or maintenance) and these data are needed to correctly calculate body parameters.

If the scales are not there, try rebooting Bluetooth on your phone: turn it off for 10 seconds, then turn it on again. Also check if the scales are connected to another device (for example, a tablet) - in which case they must first turn off in the settings of that gadget.

💡

If the scales don't turn on when you press them, check the contacts of the batteries. Sometimes they oxidize - wipe them with a cotton swab soaked in alcohol.

Alternative way: connect via Mi Fit (for older versions)

Although Zepp Life has become the main app, some users still use Mi Fit - especially if they have other Xiaomi devices (like Mi Band bracelets).

1. Download Mi Fit (Make sure it is no older than 4.6.0).
2. Register or log in to an existing account.
3. Go to Profile → Add Device → Libra → Mi Smart Scale 2.
4. Stand on the scale and wait for the vibrations - this is a signal of readiness to pair.
5. Confirm the connection in the application.

The main difference from Zepp Life is that Mi Fit may not support the latest firmware scales. If the data is not saved after connecting or the scales are permanently disabled, update the firmware through Zepp Life (even if the main application is Mi Fit).

⚠️ Note: Mi Fit doesn't automatically recognize users by weight, and if you have multiple users, you'll have to manually select a profile before each weighing.

Common mistakes and their solutions

Even with the right connection, users often face problems, and we've collected the most common errors and ways to fix them:

If none of these things worked, try to lose weight to factory settings.

1. Hold the on button (on the back) for 10 seconds until the indicator flashes red.
2. Release the button and the scales will drop.
3. Repeat the connection process again.

How to improve measurement accuracy: tips from experts

Even after a successful connection, many users complain about the difference in readings between the Mi Smart Scale 2 and the mechanical scales. This is normal - electronic scales are sensitive to external factors. To minimize the error, follow these recommendations:

• 📍 Set the scales on a flat, hard surface (tile, laminate), and a carpet or soft floor will distort the results.
• ⏱️ Weigh yourself at the same time (preferably in the morning on an empty stomach) – this will help to track the dynamics, not daily fluctuations.
• 👟 Take off your shoes and heavy clothing. Even socks can add 50 to 100 grams.
• 🔄 Calibrate the scales regularly (every 2-3 months). To do this, stand on them with a known load (for example, a weight of 10 kg) and compare the readings.

To check the accuracy, use a check weight. Take an object with a pre-known weight (for example, a bottle of water 1.5 liters = 1.5 kg) and place it on a scale. If the difference is greater than ± 100 g, calibration or replacement of batteries is required.

Sync with other services: Google Fit, Apple Health, Strava

One of the key benefits of the Mi Smart Scale 2 is the ability to integrate with popular fitness platforms, which allows you to collect all your health data in one place.

For Android (Google Fit):

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

For iPhone (Apple Health):

1. In Zepp Life, go to Profile → Settings → Applications and Services.
2. Slip Apple Health and switch on the switches for the settings you want to sync.
3. Confirm access in the system window that appears.

Once set up, the data will be automatically transmitted to the selected service each time you weigh in.Please note that certain parameters (such as bone mass or visceral fat) may not be supported by third-party platforms.

💡

Synchronization with Google Fit or Apple Health allows you to build comprehensive health charts, including data from fitness bracelets, pulse meters and other gadgets.
