How to measure weight on Xiaomi scales: instructions for all models

Xiaomi’s smart scales are no longer just a weight measurement device. Modern models like the Mi Body Composition Scale 2 or Smart Scale 2 analyze body composition, show mass index, fat level and even bone mass. But even with such functionality, many users face basic problems: scales show incorrect data, do not sync with a smartphone or do not turn on at all. This article will help you figure out how to properly weigh on Xiaomi devices, avoiding typical errors.

We're going to look at not only the measurement process, but also the nuances that are often left out in the official manuals, like why scales can show different weights when measured again, how they affect the accuracy of foot moisture, or why the data in the Mi Fit app is different from what you see on the scale screen, and you'll also learn which models support multiplayer and how to customize individual profiles for family members.

If you've just unpacked a new purchase or you've been using a scale for a while, but you want to improve your measurement accuracy, this is the guide for you. Let's start by getting the device ready for its first use.

Preparing Xiaomi’s weights for first use

Before you can get on the scale, you need to install and adjust them correctly, and even if you bought a pre-calibration device (as the manufacturer claims), a few simple steps will help you avoid future errors.

First, check the surface on which the scales will stand.

• 📏 Smooth and hard, carpet, soft linoleum, or rough floors, will distort the readings, or tile, laminate, or wood.
• 🧹 Clean – dust or small debris under the legs can lead to unstable readings.
• 🌡️ With room temperature – avoid placing near batteries, air conditioners or on a cold floor (such as in a bath after shower).

Second, install the Mi Fit app (or Zepp Life for new models) on your smartphone and sign up, without which the scales will not be able to store measurement history and analyze dynamics.

• 📱 For Android.
• 🍎 For iOS.

After installing the app, turn on Bluetooth on your phone and follow the instructions for connecting the scales. This usually takes no more than a minute: the scales should appear in the list of available devices. If the connection does not happen, try:

⚠️ Note: Some Xiaomi scale models (e.g. Mi Smart Scale 2) require firmware updates when you first connect. If the app offers software updates, agree, otherwise there may be malfunctions.

Step-by-step instructions: how to weigh on the scales Xiaomi

It would seem that it could be easier to stand on a scale and look at the result, but to get the most accurate data, you need to follow a few rules.

1. Turn on the scales. Most Xiaomi devices activate automatically as soon as you stand on them. If the screen does not catch fire, check the batteries (some models use a battery that needs to be charged via USB-Type-C).
2. Stand on the scale with bare feet. Socks or slippers will add extra grams, and wet feet (for example, after a shower) can distort the readings of impedance analysis (if your model supports body composition measurement).
3. Stand still. Spread the weight evenly on both legs, don't lean on the surroundings. Stay upright, don't bend your knees.
4. Wait for the readings to stabilize. LO Or flashing numbers, that's normal. In 3 to 5 seconds, the scales will record the result.
5. Sync the data with the app. If the scales are connected to the Mi Fit, the data will automatically go into history. If not, check Bluetooth and reconnect the device.

Important: If you use a body composition scale (such as the Mi Body Composition Scale 2) before measuring:

• 🚫 Do not eat or drink 2 hours before the procedure.
• 🚫 Do not exercise 12 hours before measurement (sweating affects accuracy).
• 🚫 Do not take measurements during menstruation (in women, this distorts the water in the body).

If the scales show an Err error or are not included, try:

• 🔋 Replace batteries (even if they are new – sometimes contacts oxidize).
• 🔄 Reset the scales: Remove the batteries for 10 seconds, then insert back.
• 📱 Reconnect the device to Mi Fit (forget the scales and add again).

How to read the measurement results: what do the numbers on the screen mean

Depending on the model, Xiaomi scales can show from 3 to 13 parameters, let’s figure out what each of them means and what to pay attention to.

Note that the accuracy of impedance analysis (measuring body composition) depends on many factors, including hydration, time of day and even the phase of the menstrual cycle in women.

• 📊 Compare data in dynamics (week/month), rather than relying on one-off measurements.
• ⏰ Take measurements at the same time (preferably on an empty stomach in the morning).
• 🩺 For medical diagnosis, use professional equipment - household scales give an error of up to 5-10% in the analysis of body composition.

If you are confused by any indicators (for example, a high percentage of fat at a normal weight), check:

• 📲 Whether Mi Fit is set up in the right height, age and gender – the norms depend on it.
• 🧍 Do you use an individual profile (if you use a weight multiple people).
• 🔋 Is the scales sufficiently charged - with a low battery charge, measurement failures are possible.

💡

If the scales show an unrealistically high percentage of muscle or a low percentage of fat, check if you stand on them in wet clothes or with wet feet.

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes that lead to inaccurate measurements, and here are the most common ones and ways to fix them:

1. The scales show different weights when repeated measurements.

Reasons:

• 🪨 Uneven surface (even a slight slope of 1-2)° gives an error of up to 500g).
• 👟 Socks or shoes (added 100-300g).
• 🌀 Uneven weight distribution (for example, if you lean on one leg).

Solution: Stand on the scale 3 times in a row and average the result. Most Xiaomi models do this automatically, if you do not take your feet off the platform for 5-10 seconds.

2.The data in Mi Fit does not match the scale screen.

It's okay! The app can do this.

• 📉 Round-up values (e.g. 72.3 kg) → 72 kg).
• 🔄 Use the last successful measurement if the synchronization is interrupted.
• 🧮 Apply smoothing algorithms (e.g., ignore sudden weight surges).

To check for accurate raw data, close the app, turn off Bluetooth, then turn it on again and stand on the scale.

3. The scales are not included or show an error.

The most common error codes and their value:

• LO — Low battery charge or weak signal (for Bluetooth models).
• Err is a measurement error (maybe you have moved or the surface is uneven).
• --- — The scales are not calibrated (you need to reset the settings).

⚠️ Note: If Xiaomi Mi Body Composition Scale 2 shows an error E8, This means a problem with the body composition sensors, so try to wipe the electrodes (metal strips on the platform) with an alcohol wipe.

How to set up a multi-user mode

One of the key benefits of Xiaomi’s smart scales is the ability to create individual profiles for each family member.

• 👨‍👩‍👧‍👦 Tracking the progress of each user separately.
• 📊 Get personalized nutrition and exercise recommendations.
• 🔒 Avoid confusion in data (for example, when the scales confuse husband and wife).

To add a new user:

1. Open the Mi Fit or Zepp Life app.
2. Go to the Profile section → Devices → Your scales. → User management.
3. Click Add User and enter data (height, age, gender).
4. Now, when weighing, the scales will automatically recognize the user by weight and impedance.

If the scales confuse users, try:

• 🔄 Recalibrate the scales: stand on them, then take off your legs and stand up again.
• 📱 Update the device firmware through the application.
• 🧍 Weigh yourself at different times (such as morning and evening) to make your scales “remember” your biometrics.

For face recognition models (such as the Xiaomi Smart Scale 2 with a camera), setting up is even easier:

1. Stand on the scale and wait until the suggestion to create a profile appears on the screen.
2. Follow the instructions on the screen (you will need to take a selfie for recognition).
3. Now the scales will automatically identify you.

Synchronization with other applications and services

Xiaomi scale data can be exported to other fitness apps like Google Fit, Apple Health or S Health.This is handy if you use multiple trackers or want to analyze data in one place.

To enable synchronization:

1. Open Mi Fit and go to Profile → Settings → Accounts and Sync.
2. Select a service (e.g. Google Fit) and log in.
3. Allow access to data on body weight and composition.

Please note:

• 🔄 Synchronization can take up to 24 hours (depending on the service).
• 📊 Not all parameters are passed to third-party apps, such as Apple Health taking weight and IMT, But it can ignore muscle mass data.
• 🔒 For privacy, you can turn off the transmission of specific metrics (for example, fat percentage).

If the synchronization is not working:

• 📱 Check that the smartphone settings allow access to Fitness and health for Mi Fit.
• 🔄 Restart the application and reconnect the account.
• 📋 Make sure that the Mi Fit profile shows the correct height and gender – without this, the data will not be transmitted correctly.

💡

For accurate dynamics analysis, use a single application (e.g., only Mi Fit or only Google Fit) synchronizing between multiple services can duplicate data and distort graphs.

Weight care and extension of service life

To make Xiaomi scales last a long time and show accurate data, it is enough to follow a few simple rules:

Cleaning and storage:

• 🧼 Wash the platform with a soft, damp cloth after each use (especially if weighed with bare feet).
• 🚫 Do not use abrasive detergents – they will damage the touch screen and metal electrodes.
• 🌡️ Keep the scales in a dry place at room temperature (10–35)°C).

Batteries and power:

• 🔋 In battery models (such as Mi Smart Scale), replace the batteries every 6-12 months, even if the scales are still working.
• 🔌 In battery models (such as the Mi Body Composition Scale 2), avoid full discharge – recharge at a charge level below 20%.
• ⚡ Use only the original cable or a certified USB-Type-C voltage to charge. 5V.

Sizing:

Over time, the weight sensors can get lost, to get back to accuracy.

1. Turn on the scales and wait until 0.0 appears on the screen.
2. Knock carefully on the corner of the platform (this will reset the internal calibration).
3. Stand on the scale and compare the readings with the mechanical scales (acceptable error — ±100g).

⚠️ Note: If the scales are 500 grams or more different from the real weight after calibration, this may indicate damage to the sensors. In this case, contact the service center - self-repair will lead to loss of warranty.
