How to Use Xiaomi Smart Scale: A Complete Guide from Setup to Data Analysis

Xiaomi Smart Scale (including Smart Scale 2 and Smart Scale Pro) has long been a popular health-monitoring gadget that not only shows weight, but also analyzes body composition β€” percent of fat, muscle, water, and even bone mass. However, many users face difficulties in how to properly sync a device with the Mi Fit app, decrypt the data obtained or fix connection errors.

In this article, we'll take you through all the steps of weight management, from unpacking to advanced functions, how to avoid typical weighting errors, what parameters are really important for your goals (weight loss, weight gain or keeping fit), and what to do if the scales are no longer synchronized, and compare the Smart Scale 2 and Pro models to see if you should overpay for additional sensors.

1.Preparation and preparation for the first use

In the Xiaomi Smart Scale box you will find:

  • πŸ“¦ The scales themselves (white or black platform of tempered glass)
  • πŸ”‹ 4 type batteries AAA (In some versions, the built-in battery)
  • πŸ“„ Short instructions in several languages (including Russian)
  • πŸ“± QR-code for downloading the Mi Fit application

Before the first inclusion, be sure to check:

  1. The presence of a protective film on the touch panel (it must be removed!).
  2. Proper battery installation (observe polarity) +/βˆ’).
  3. A flat surface for weighing (a carpet or soft coating will distort the results).

πŸ’‘

If the scales are not turned on after the batteries are installed, press the platform with your foot - sometimes the contacts are oxidized during storage.

Smart Scale Pro models are equipped with a built-in 200 mAh battery, which is charged via Micro-USB. Full charge is enough for 6-8 months with daily use. ~2 hours, status signaled by the indicator under the platform (red – charged, green – full charge).

2. Connect to the Mi Fit application: step-by-step instructions

Xiaomi Smart Scale is only paired with the official Mi Fit app (available for Android and iOS). Without it, you will only see weight, without body composition analysis.

  • πŸ€– Google Play
  • 🍎 App Store

Follow the algorithm further:

  1. Sign up or sign in to your Xiaomi account (via Google/Facebook).
  2. Click Profile β†’ Add the device β†’ Libra.
  3. Select the model (Smart Scale 2 or Pro) and allow access to Bluetooth and Notifications.
  4. Stand on the scale, and you'll see a 4-digit code on the display, and you'll enter it into the app.

3. How to weigh properly: 7 rules for accurate data

The accuracy of the Xiaomi Smart Scale readings depends not only on the calibration of the device, but also on how you take measurements.

ParameterRecommendationWhy is it important?
Time of dayIn the morning, immediately after waking up.In the evening, weight can increase by 1-2 kg due to food and fluids.
ClothesMinimum (better without clothes)The fabric absorbs moisture and adds 200-500 g to the real weight.
Surface.Hard floor (tile, laminate)Carpet cushioning pressing, distorting bioimpedance data
Position.Stand still, legs shoulder wide.Uneven weight distribution affects body composition analysis

Critical error: weighing yourself after a workout or bath. Because of the loss of water through sweat, the scales will show an understated percentage of fat, and after 1-2 hours (after restoring water balance), the data will change. For objectivity, take measurements at the same time, before eating and drinking water.

Why do the scales show different weights when weighing again?
This is OK! Xiaomi Smart Scale uses bioimpedance technology, which is sensitive to the distribution of fluid in the body. If you stand on the scale right after drinking water or going to the toilet, the readings can vary by 200-300 g. To be accurate, take 2-3 consecutive measurements and take the average.

For analysis of dynamics (not absolute figures!) it is important:

  • πŸ“… Weigh yourself daily at the same time.
  • πŸ“Š Compare data for the week, not by day (weight fluctuates due to hormones, stress, nutrition).
  • 🩺 Consider the menstrual cycle (in women 3-5 days before menstruation, weight may increase by 1-3 kg due to fluid retention).

Decoding of indicators: what do the figures in the annex mean

Mi Fit shows up to 13 parameters, but most users don't understand what they mean.

  • Weight is an obvious indicator, but its dynamics are more important than absolute values, a decrease of 0.5-1 kg per week is considered a healthy rate of weight loss.
  • EMIT (BMI) β€” Body mass index: Normal: 18.5–24.9, but BMI does not take into account muscle mass (athletes may show β€œobesity” with a low percentage of fat).
  • Body Fat is the norm for men: 10-20%, for women: 20-30%, and it is dangerous if below 5% (in men) or 13% (in women) is a sign of exhaustion.
  • Muscle mass is the ideal weight for the average person, which is 35-45% of the total weight.
  • Water is normal: 50-60%, below 45% is a sign of dehydration.
  • Bone Mass: Must be at least 3 to 5 percent of your body weight, and a decrease may indicate osteoporosis.
  • Visceral Fat is the most dangerous type of fat surrounding the internal organs, Normal: 1-12, Above 13, risk of diabetes and heart disease.

Attention! Smart Scale 2 and Pro can differ by 2-5% due to the different number of electrodes, the Pro is more accurate due to 4 additional sensors on the legs that analyze the composition of the body by segments (arms, legs, torso).

πŸ’‘

To measure your health objectively, look not at individual numbers, but at their ratios, for example, a high percentage of water with low muscle mass may indicate swelling rather than being fit.

If your numbers are out of the norm:

  • πŸ— High percentage of fat β†’ Increase protein in your diet and add strength training (cardio is ineffective for burning fat).
  • πŸ’ͺ Low muscle mass β†’ Calorie deficit + Weight training 3 times a week.
  • πŸ’§ Low water level β†’ Drink 30 ml/kg of weight per day (for example, at 70 kg - 2.1 l).

5. Typical errors and their elimination

Even with the right setup, users face problems, and here are the most common ways to solve them:

Problem.Reason.Decision
Libras not includedBatteries discharged or software failureReplace the batteries. If it doesn't work, reset the settings (hold the button). SET 10 seconds)
Not synchronized with Mi FitBluetooth Failure or Outdated FirmwareReboot your phone, update the app, reconnect the scales
Showing Lo's mistakeWeak signal or low chargeMove the scales closer to the router (for Pro) or replace the batteries
Data not storedNo Internet connection.Turn on mobile internet or Wi-Fi on your phone

If the scales show unrealistic values (for example, 50% fat percentage at normal weight):

  1. Check if the gender and age are correctly entered in the Mi Fit profile.
  2. Make sure you are standing bare feet (socks distort bioimpedance).
  3. Calibrate: Stand on the scale, then take off the weight and stand up again.

πŸ’‘

If after updating the firmware scales began to work incorrectly, roll back to the previous version of the software. To do this, in Mi Fit, go to the Device Profile β†’ Settings β†’ Reverse the update.

If the Smart Scale Pro scales have stopped charging:

⚠️ Do not use chargers with higher current strength 1A - it can damage the battery. Xiaomi's original adapter has an outlet 5V/1A. If the scales don't respond to charging, check the cable for damage or try another one. USB-port.

6.Model comparison: Smart Scale 2 vs Smart Scale Pro

At first glance, both models look the same, but there is a difference -- and it's a big difference for people who are serious about health.

Who is the Smart Scale 2:

  • 🏠 Those who want basic weight and body composition control without overpaying.
  • πŸ‘¨β€πŸ‘©β€πŸ‘§β€πŸ‘¦ Families (weights support up to 16 profiles).
  • πŸ’ͺ Beginner athletes (accuracy is enough to track progress).

Who should choose Smart Scale Pro?

  • πŸ‹οΈβ€β™‚οΈ Professional athletes (accurate analysis of muscle mass by segment).
  • 🩺 People with medical conditions (for example, controlling visceral fat in diabetes).
  • πŸ”‹ Those who do not want to spend on batteries (built-in battery).

πŸ’‘

If your goal is to lose weight rather than build muscle, it makes no sense to overpay for the Pro, and the difference in fat accuracy between models is minimal (1-2 percent), but the price is almost 1.5 times.

7 Advanced Features: How to Make the Most of the Scales

Few people know, but Xiaomi Smart Scale is more than just a weight display, and here are some hidden features that can be used for in-depth analysis:

  • πŸ“ˆ Data export: In Mi Fit, you can unload the measurement history in CSV (Go to Profile. β†’ Settings β†’ Data export. This is convenient for analysis in Excel or for transfer to the doctor.
  • πŸ‘Ά Pregnancy mode: Included in profile settings. Libra adapts algorithms to changes in body composition during pregnancy (e.g., not counting fluid as "overweight").
  • πŸ† Goals and Achievements: Set a weight target in Mi Fit and the app will show progress, motivating messages and nutrition tips.
  • πŸ”„ Connect Mi Fit to Google Fit, Apple Health or Strava so that data is automatically transferred to your favorite fitness apps.

For Smart Scale Pro, additional options are available:

  • 🦡 Segment analysis: Shows the distribution of muscle and fat in the arms, legs and trunk, useful for correcting workouts (for example, if fat accumulates mostly in the legs).
  • πŸƒ Sport mode: Measures weight taking into account fluid loss after exercise (adjusts water and fat indicators).

Attention! If you use scales for medical purposes (e.g., controlling swelling in kidney disease):

⚠️ Xiaomi Smart Scale data is not diagnostic! Professional equipment (e.g., bioimpedance analysis in the clinic) is required to make a diagnosis. Home scales give an error of up to 5% and are only designed to track dynamics.

8. Alternative applications: can you use Mi Fit?

The official Mi Fit app isn't popular with everyone because of limited analytics and advertising. Fortunately, Xiaomi Smart Scale scales support third-party programs:

  • πŸ“Š Google Fit syncs with Mi Fit automatically, plus integration with other gadgets (like Fitbit) minus: no detailed analysis of body composition.
  • 🍎 Apple Health is suitable for iPhone owners, stores the history of measurements, but does not show graphics.
  • πŸ“² Yazio is a fitness app with a calorie calculator that imports data from Mi Fit and makes weight loss predictions.
  • πŸ‹οΈ FatSecret, which specializes in dietary control, shows how fat percentage changes depending on your diet.

To connect the scales to a third-party application:

  1. In Mi Fit, allow access to data (Profile) β†’ Settings β†’ Applications and services).
  2. In a third-party app, look for the Devices or Sync section and select Xiaomi Smart Scale.
  3. Confirm the accounts' connection.

Important: When using third-party applications:

  • βœ… Data will be duplicated (e.g. in Mi Fit and Google Fit at the same time).
  • ❌ Certain parameters (e.g., visceral fat) may not be transmitted.
  • ⚠️ Disabling Mi Fit will result in loss of measurement history (libras do not store data locally!).

FAQ: Answers to Frequent Questions

πŸ”Ή Why do scales show different weights at each weighing?
This is normal because of: fluid fluctuations in the body (drinking water, sweating); different weight distribution on the platform (stand still, legs shoulder wide); sensor errors (up to the point of separation). Β±100g for weight, up to Β±3% for body composition. To be accurate, take 2-3 consecutive measurements and take the average.
πŸ”Ή Can I weigh myself in clothes or socks?
You can, but: Clothing adds 200-500 grams to weight. Socks distort the bioimpedance analysis (percentage of fat, muscle). For accuracy, weigh yourself without clothes or in the same set (for example, always in your underwear).
πŸ”Ή How to Lose Scales to Factory Settings?
Two ways are possible: Software reset: In Mi Fit, go to Device Profile β†’ Settings β†’ Remove the device. Hardware reset: Turn off the scales (remove the batteries or hold the button). SET 5 seconds. Press and hold. SET 10 seconds until the display flashes. Release the button, the scales will reset.
πŸ”Ή Why the app doesn't have data for today, even though I weighed in?
The problem could be: No internet on your phone (data is only synchronized when connected); Bluetooth failure (reset your phone); Profile error (check that Mi Fit has the correct gender and age); To recover data: Stand on the scale again; in Mi Fit, pull the screen down to update the data.
πŸ”Ή Can I use a scale without a phone?
Yes, but with limitations: Libras will only show weight (without body composition analysis). Data will not be saved in history. Smart Scale Pro without a phone is not available mode "Sport". If the phone is dead, the scales will retain the last dimension in their memory, but only until the next weigh.
