How to connect the floor scales Xiaomi Smart Scale 2 to the smartphone: instruction 2026

Introduction: Why Xiaomi Smart Scales Are Needed and How They Work

The Xiaomi Smart Scale 2 is not just a weight measurement device, but a full-fledged fitness tracker that analyzes 13 key body parameters, from body mass index (BMI) to visceral fat. Unlike classic mechanical scales, this model synchronizes with a smartphone via Bluetooth, stores measurement history and integrates with Mi Fit, Apple Health and Google Fit applications.

The main advantage of the device is accuracy up to 50 g (weighing up to 150 kg) and automatic recognition of users by weight. For example, if the scales are used by several family members, the device will independently determine who is on the platform and write the data in the appropriate profile. But in order for all these functions to work, you need to connect the scales to the phone correctly, and many have difficulties.

In this article, we'll take a step-by-step connection instruction, look at common errors (such as when the scales are not in the app), and give you tips for setting up for maximum measurement accuracy. And if you've tried to sync your device and nothing has worked, there's a section at the end of the article that solves 90% of the problems.

What is included in the kit and how to prepare the scales for connection

Before you start setting up, check the configuration of Xiaomi Smart Scale 2. The box should be:

• 📦 The scales themselves (white or black, depending on the version)
• 🔋 4 type batteries AAA (sometimes sold separately)
• 📄 Short instructions in several languages (including Russian)
• 🔄 Reset button (hidden under the battery compartment cover)

If you don't have any batteries, use alkaline (not rechargeable!) 1.5V. Cheap salt batteries can run out quickly, causing weight failures. Also, pay attention to the protective film on the touchpad - it needs to be removed before first use (many forget this!).

To prepare the scales for connection:

1. Turn the device over and remove the battery compartment cover (a coin or a flat screwdriver will be required).
2. Install batteries while observing polarity (+ and − hull-drawn).
3. Press the on button (also called the reset button) once – the 0.0 symbol should appear on the display.
4. Put the scales on a flat, hard surface (not on a carpet!).

💡

If the batteries don't light up, check the contacts, sometimes they oxidize. Wipe them with a swab or cotton swab soaked in alcohol.

Installation of the Mi Fit application: which account to start with

Xiaomi Smart Scale 2 is powered by the official Mi Fit app (for Android and iOS). Alternative programs like Zepp Life or Google Fit can read Mi Fit data, but you can't connect the scales directly through them.

• 🤖 Mi Fit for Android
• 🍎 Mi Fit for iOS

Once installed, you need to sign up or log in to an existing Xiaomi account, and here's an important caveat: if you already have an account (like a Redmi or POCO smartphone), use it. You don't have to create a new one, all Xiaomi devices are tied to a single profile. If you forget your password, it will be difficult to restore access to the scale data.

When first launched, Mi Fit will request access to:

• 📱 Notices (to remind you of the weighting)
• 📍 Geolocation (for accurate BMI calculation, taking into account the region)
• 🏃 Health data (for synchronization with Apple) Health/Google Fit)

How to connect Xiaomi Smart Scale 2 to your phone

Now, to the most important thing, synchronize the scales with your smartphone, follow the instructions in strict order to avoid errors:

1. Open Mi Fit and go to the Profile tab → Add the device.
2. Select the Libra category and find the Xiaomi Smart Scale 2 model (if it’s not on the list, update the app!).
3. Click “Connect” – the application will start searching for the device.
4. Stand on the scales (the display should appear Bluetooth symbol or flashing indicator).
5. Wait for the vibration – this is a signal of successful connection.
6. Fill out the profile: specify gender, age, height and purpose (weight loss, maintenance of shape or weight gain).

If it's successful, the app will have a section with the history of weighings, the first measurement can take up to 10 seconds - the scales need to be calibrated, after you connect, do not turn off Bluetooth on your phone, otherwise the data will not sync automatically.

Setup multiple users: how scales distinguish family members

One of the key advantages of Xiaomi Smart Scale 2 is that it supports an unlimited number of users, and the scale automatically recognizes who has joined the platform by weight (with an error of ± 2 kg).

1. Create profiles for each family member in Mi Fit (Install Profile) → Family).
2. Indicating height, age and gender for each person affects the calculation of BMI and percentage of fat.
3. Conduct the first weighing for each user in turn (with an interval of 10 seconds).

If the scales confuse users (for example, a husband and wife are of similar weight), you can manually select a profile in the app after weighing.

• ⚖️ Weight difference between users greater than 2 kg.
• 📱 All family members use one Mi Fit app (with different Xiaomi accounts).
• 🔄 Scales updated to the last firmware (checked in the device settings) → Update).

Typical Connection Problems and Their Solutions

Even with the correct following of the instructions, there can be difficulties, and we have collected the most common errors and ways to fix them:

If the scales are connected, but show the wrong weight (for example, overestimate or underestimate by 1-2 kg), perform calibration:

1. Stand on the scale and wait for a stable reading.
2. Press the reset button on the back and hold it for 5 seconds.
3. After the vibration, get off the scale and wait 10 seconds.
4. Repeat the weighting – the data must be updated.

💡

If the scales stopped syncing after the Mi Fit update, remove the device from the application (Profile → Xiaomi Smart Scale 2 → Delete) and connect again.

How to Update Your Scale Firmware and Why It Matters
