Xiaomi floor scales: how to choose, connect and use without errors

Xiaomi’s electronic floor scales are no longer just a weight measurement device. Today, they are smart gadgets integrated into the Mi Home ecosystem, able to analyze body composition, sync with a smartphone and even make health recommendations. But how not get lost in the variety of models — from the budget Mi Body Composition Scale to the premium Xiaomi Smart Scale 2? And most importantly, how to set them up correctly so that the data is accurate and the connection is stable?

In this article, we will look at all the key aspects of working with Xiaomi scales, from choosing a model for specific tasks to solving typical problems such as synchronization errors or incorrect readings, and pay special attention to hidden functions that the manufacturer does not mention in the instructions – for example, how to lose weights to factory settings without a smartphone or why fat mass data may differ from medical tests.

If you're just planning to buy, at the end of this article, there's a comparison table of models with current prices and characteristics. Have you already bought, but scales are "glutching"? FAQ-section or in the block for troubleshooting.

1. What Xiaomi floor scales are: a comparison of models 2023-2026

Xiaomi’s smart scale range includes more than 10 models, but only 4-5 are actively represented on the market. The main differences lie in the accuracy of sensors supported by metrics (for example, muscle mass analysis or water level analysis) and design.

• 🔹 Xiaomi Mi Body Composition Scale 2 is the most popular model with 13 body analysis metrics (weight, BMI, fat/muscle mass, bone density, etc.). Supports up to 16 users, runs from 4 batteries AAA.
• 🔹 Xiaomi Smart Scale 2 is a premium version with improved sensors for measuring blood viscosity and protein levels (a unique feature among household scales.
• 🔹 Redmi Smart Scale is a budget option with basic metrics (weight, BMI, fat/muscle). No Bluetooth 5.0, so syncing with a smartphone can slow down.
• 🔹 Xiaomi Mi Scale Lite is a simplified version without body composition analysis, suitable for those who only need an accurate weight with an error of up to 50 g.

Importantly, all models except the Mi Scale Lite require Mi Fit or Zepp Life to work properly. Without a smartphone, you'll only see the weight on the display, the rest of the data will be unavailable.

If you want the maximum metrics for your body or your athletic performance, take the Mi Body Composition Scale 2. For basic use, the Redmi Smart Scale is enough. But the Smart Scale 2 is only worth taking if you need to monitor protein levels and blood viscosity, which is redundant for most users.

2. How to connect Xiaomi scales to the phone: step-by-step instructions

The process of connecting the scales to the smartphone takes no more than 5 minutes, but many users face errors during the synchronization stage.

Step 1: Installation of the application

Download Mi Fit (for the first time) Android/iOS) Or Zepp Life (Android only) Note that with 2023 Xiaomi is gradually moving users to Zepp Life, but both programs remain compatible with weights.

Step 2: Registration of an account

If you already have a Xiaomi account (for example, for a smartphone or fitness bracelet), use it. If not, register via email or phone number. Without an account, the scales will not be able to store your measurement history.

Step 3: Adding a device

Open the application, go to the Profile section → Add the device → Libras. Select your model from the list. Follow the instructions on the screen.

Step 4: Synchronization

Stand on the scale, your weight should appear on the display, the data will be automatically transmitted to the application.

• 🔋 Check the battery charge (if the scales are not on, replace the power cells).
• 📶 Make sure that your smartphone is Bluetooth enabled and GPS (for some).
• 🔄 Reset the scales: Remove the batteries for 10 seconds, then insert back.

Install the Mi app Fit/Zepp Life|

Register a Xiaomi | account

Turn on Bluetooth and GPS on your smartphone |

Insert batteries into the scale (polarity!)|

Update the firmware of the scales (if available)-->

⚠️ Note: If Xiaomi scales are not connected to the iPhone, try disabling the Bluetooth Limits feature in iOS settings (Settings) → Bluetooth → The limit of Bluetooth → Off. That's a common cause of sync issues on Apple devices.

3. Measurement accuracy: why Xiaomi scales lie and how to fix it

Measurement error is one of the most common complaints about Xiaomi scales. ±50 g, but in practice the spread can reach 200-300 g. What is the cause and how to minimize errors?

Reasons for inaccurate statements:

• 🏠 The scales must stand on a hard, flat floor (tile, laminate), the carpet or soft linoleum distorts the data.
• 🔋 Batteries are low, sensors are unstable, and you need to change the batteries every 6 to 12 months.
• 🧍 You have to stand barefoot, spread the weight evenly on both legs, don't lean on the wall or furniture.
• 🌡️ Temperature changes: If the scales are stored in the cold (for example, on the balcony), before using, let them heat up to room temperature (15-20 minutes).

How do you calibrate the scale?

Most Xiaomi models don’t have manual calibration, but you can reset the settings:

1. Hold the on button (if any) or tap the scale sensor and don’t let go for 10 seconds.
2. It'll appear on the display. CAL or 0.0, which means the scales have dropped.
3. Stand on the scale again, and automatic calibration will occur.

⚠️ Attention: If the scales show a weight of 2-3 kg more than the real one, check if they are standing on a long-pile carpet.° You may add extra pounds to the readings.

💡

To check the accuracy of the scales, use a control load – for example, a bottle of water with a volume of 1 liter (≈Weigh it on Xiaomi scales and compare it to a reference weight.

4. Body composition analysis: what do all these numbers mean?

Xiaomi scales measure not only weight, but also a number of other parameters: fat mass, muscle mass, water level, bone density, etc. Let’s figure out what these metrics mean and how much you can trust them.

Key indicators and their standards:

⚠️ Attention: The body composition data on Xiaomi scales (as with any household bioimpedance scale) have an error of up to 5-10%. For medical diagnosis, use professional equipment. However, to track the dynamics (for example, reducing fat mass during diet) the accuracy of the weights is sufficient.

How do scales measure body composition? They use bioimpedance analysis, which is to pass a weak electrical current through the body and analyze tissue resistance. Fat tissue conducts current worse than muscle or water, so the instrument can calculate the percentage.

Why can the data differ from the medical tests?

• 🕒 Time of day. In the morning, the water level in the body is higher, so the percentage of fat will be lower than in the evening.
• 🍽️ Eating. After eating or drinking alcohol, water and fat are distorted.
• 🏋️ After exercise, muscles are saturated with blood, which increases their weight in the overall body composition.

5. Synchronize with Mi Fit and other applications

Xiaomi scales transfer data to Mi Fit or Zepp Life, but they can be exported to other services: Google Fit, Apple Health, Strava, etc. We will figure out how to configure integration and avoid data loss.

How to connect Mi Fit to Google Fit/Apple Health:

1. Open Mi Fit, go to Profile → Settings → Accounts and synchronization.
2. Select Google Fit or Apple Health and sign in.
3. Allow access to data on body weight and composition.

⚠️ Note: If the data is not synced with Apple Health, check if the Health Record option is enabled in the Mi Fit settings. Also make sure that the iPhone allows Health access for the Mi Fit app. → Confidentiality → Health).

Export of data to Excel/Google Sheets

To save the measurement history for analysis, you can export the data manually:

• In Mi Fit go to Profile → Weight. → History.
• Click on the three dots in the upper right corner and select Data Export.
• The file will be saved in.csv format, which can be opened in Excel or Google Tables.

If you need automatic synchronization with tables, use the service IFTTT Zapier to create rules for exporting data from Mi Fit to Google Sheets.

💡

For an accurate analysis of the dynamics, weigh yourself at the same time of day (preferably on an empty stomach in the morning) and in the same clothes (or without it).

Typical problems and their solutions

Even the most reliable scales Xiaomi can fail.-5 problems and ways of eliminating them:

1. Libras are not included

• 🔋 Check the batteries (even if they are new, the contacts may have oxidized - wipe them with a wool of alcohol).
• 🔌 Make sure the batteries are inserted correctly (polarity!).
• 🔄 Press and hold the touch button for 15 seconds to reset.

2. Phone connection error (Err code)

• 📱 Reboot your smartphone and scales.
• 🔄 Remove the scales from the list of devices in Mi Fit and connect again.
• 📲 Update the Mi Fit app to the latest version.

3.The scales show the wrong weight

• 🧹 Place the scales on a flat, hard surface (not on the carpet!).
• 🧘 Stand on the scale without shoes, spreading the weight evenly.
• 🔧 Calibrate (see section 3).

4. Body composition data not updated

• 📱 Check that the Mi Fit profile shows the correct height, age and gender.
• 🔋 Replace batteries – at low charge, bioimpedance analysis may not work.
• 🩺 Make sure you weigh yourself at the same time (in the morning on an empty stomach).

5. Libras do not retain measurement history

• 📱 Check that you are logged in to Xiaomi account in the Mi Fit app.
• 🔄 Sync data manually: Open Mi Fit, go to the weights section and pull the screen down for an update.
• 📲 Update the firmware of the scales (if available).

If none of the methods helped, try to lose weight to factory settings:

1. Hold the touch button for 10-15 seconds until the display appears. CAL or 0.0.
2. Remove the scales from the batteries for 1 minute, then insert back.
3. Reconnect the scales to the phone.

7. Xiaomi weights comparison with analogues: which is better to choose?

Xiaomi scales are not the only option in the smart gadget market, but let’s look at how they compare to competitors in key ways:

What to choose?

• 💰 Budget up to 4,000 ₽: Xiaomi Mi Body Composition Scale 2 or Huawei Smart Scale 3. The former win in accuracy and number of metrics, the latter in integration with the ecosystem of Huawei.
• 🩺 Medical Precision: Withings Body+ Garmin Index S2. They are more expensive, but their data is closer to professional analysis.
• 📱 Best synchronization: Withings – supports the maximum number of third-party applications.

⚠️ If you want to be self-sufficient, check out the Garmin Index. S2 — It's powered by the grid (no need to change batteries) Xiaomi scales require a battery replacement every 6-12 months.
