Xiaomi Mi Body Composition Scale 2: The Complete Guide

Modern health gadgets are no longer just a toy and have become full-fledged tools for monitoring physical health. Xiaomi smart scales allow you to track not only body weight, but also percentage of fat, muscle mass, water and even bone tissue. However, to properly work the device requires a competent initial setting, which often raises questions for beginners in the Mi Home ecosystem.

The process of synchronizing equipment with a smartphone is based on the operation of the Bluetooth protocol and a specialized application, which requires careful attention to detail. Incorrect sequence of actions can lead to the fact that the scales will not transmit data or show a calibration error. In this article, we will discuss in detail each step of installing the Xiaomi Mi Body Composition Scale 2 so that you can immediately start to get accurate statistics about your body.

Before we get to the software part, it's important to make sure that the device is physically ready to go, and that's a basic requirement that's the reason for half of all connectivity problems, and to activate the scales, you have to remove the protective film from the contacts of the battery compartment, because the device comes in sleep mode to save charge, and then zeros will appear on the display, signaling readiness for pairing.

Preparation for the first launch and installation of batteries

The process starts with checking the configuration and installation of the batteries. Unlike many other household appliances, these scales are powered by four standard AAA batteries that provide stable data transfer over Bluetooth Low Energy. It is important to use high-quality alkaline cells, since cheap analogues can quickly discharge under the load of a wireless module.

Turn the device downwards and open the battery compartment, and you'll see a contact group inside, and maybe a plastic insulator, and after removing the insulator and putting the batteries in polarity, the glass surface should light up briefly, or the weight value should appear, and if that doesn't happen, check the density of the contacts.

For stable operation of the device, it is recommended to choose a flat hard surface, for example, tile or laminate. Carpet, even with a short pile, can make significant errors in measurements, since the legs of the scales will miss the coating. Calibration occurs automatically when first turned on, but for this the scales must stand still.

⚠️ Note: Do not put the scales on soft or fluffy carpets, otherwise the measurements will be incorrect, and the risk of damage to the body will increase.

Once installed, the scales are ready for software setup. Make sure your smartphone is in close proximity to the device, as the Bluetooth range is limited to a few meters.

Selection and installation of management applications

A key element of Xiaomi’s ecosystem is software that collects and analyzes data. There are two main applications for working with these scales: Mi Fit (which is gradually renamed Zepp Life) and Xiaomi Wear (or Mi Fitness). The choice depends on the version of the firmware of the scales and the region, but the most versatile and time-tested option remains the Zepp Life bundle.

Download the app from the official Google Play or App Store. Do not use third-party apps APK-Files from unverified sources to avoid the risk of malware infecting your device. Once installed, launch the app and create a Mi Account if you don't already have one.

  • πŸ“± Download the official Zepp Life or Mi Fitness app from a trusted source.
  • πŸ“ Register using your phone number or email address.
  • πŸ”’ Confirm the entrance through SMS-code or email to activate profile.
  • βš™οΈ Allow the app to geolocate and Bluetooth, otherwise device search will be impossible.

The interface may seem overloaded, but to get started, we only need the add-on section. In older versions of Mi Fit, this was done through a profile, in newer versions of Zepp Life, the add-on button is on the home screen or in the Profile tab. The system will offer to scan itself QR-code or find a device nearby.

The process of pairing weights with a smartphone

The most important step is to connect the hardware directly to the phone. Open the app and go to add the device. Select Libra or click the plus in the corner of the screen. The app will request permission to use Bluetooth, which must be confirmed.

Stand on the scale with one foot to make the screen catch fire, but don't wait for the full weigh-in. At this point, the list of available devices should appear on the smartphone screen. Find the Mi Body Composition Scale 2 and click "Connect." The process takes no more than 10-15 seconds.

If the scales are not there, try rebooting Bluetooth on your smartphone or completely closing and reopening the app. Sometimes it helps to remove the device from the list of paired in the system settings of Android or iOS before trying again to search.

β˜‘οΈ Checklist of successful connection

Done: 0 / 5

Once the connection is successful, the app may suggest updating the firmware scales. Updating firmware is a critical step, as new versions correct errors in body composition algorithms and improve connection stability. Don't interrupt this process and keep the phone near the scales until it's complete.

Setting up a user profile for accurate calculations

The accuracy of your fat and muscle mass calculations depends on the personal data you enter. The algorithm uses formulas that take into account height, age, sex and physical activity levels, and if these data are wrong, then all subsequent measurements will become meaningless.

Go to the user profile in the app and fill in all the fields carefully, pay special attention to growth, as it is a constant in most bioimpedance formulas, and choose the right level of activity, from sedentary lifestyle to professional sports.

If you have multiple users, you can create up to 16 profiles in the app, automatically recognize the user by weight and parameter ratio, assigning data to the appropriate account, and guests often have a Guest mode, which is not stored in history.

⚠️ For pregnant women and people with pacemakers, the use of bioimpedance analysis (body composition measurement) is not recommended by the manufacturer.

Data interpretation and metrics

Once you've adjusted the scales, they'll show 13 different metrics, and understanding what each means will help you manage your health more effectively, and the main metric is BMI, but it doesn't take into account muscle-fat ratios.

The more important parameter is the percentage of body fat, which is considered normal for men to be 10-20%, for women - 20-30%, and also the indicator of visceral fat, which surrounds the internal organs, and its excess is dangerous to health even in normal appearance.

What is basal metabolism?
Basal metabolism is the amount of energy (calories) your body uses at rest to maintain its vital functions (breathing, circulation, brain function), which helps calculate the daily calorie requirement for weight loss or weight gain.

Watch the dynamics of changes, not single values. Weight can fluctuate throughout the day due to water balance, so it is best to weigh yourself on an empty stomach in the morning, after going to the toilet and before breakfast, which will provide the most stable and comparable results.

For maximum accuracy, weigh in the minimum of clothing and at the same time of day to exclude the influence of external factors on the result.

Solving common problems and errors

In the process of operation, users may encounter a number of typical problems. Most often, scales show a Lo or Err error. Lo code means low battery charge to be replaced. Err code usually indicates overload (exceeding the limit of 150 kg) or that the scale is standing on an uneven surface.

If the scales are no longer synced with your phone, try removing the device from the app and adding it again. It's also worth checking if the smartphone operating system is blocking the application from running in the background. In the phone's battery settings, allow Zepp Life or Mi Fitness to have unlimited background activity.

  • πŸ”‹ Lo Error – Replace all 4 batteries with new ones.
  • βš–οΈ Err – Check the installation surface and user weight.
  • πŸ“‘ No sync – restart Bluetooth and check OS permissions.
  • πŸ“‰ Unstable readings – stand up evenly, spreading the weight evenly on both feet.

Sometimes it helps to completely reset the scales. To do this, remove the batteries for 10-15 seconds, then insert them back in, which will restart the device controller and can eliminate software failures.

πŸ’‘

Most of the errors of Xiaomi scales are not due to a breakdown, but to discharged batteries or improper installation of the device on a soft surface.

How to lose weight Xiaomi Mi Body Composition Scale 2 to factory settings?
To reset completely, remove all batteries from the bay. Leave the scales without power for at least 30 seconds. Insert new batteries. Libra will reset the current temporary data and go into standby mode, and the data in the application will not be deleted if the account is saved.
Can I use a scale without the Internet?
Yes, scales can measure weight without the Internet, but to transmit data to your phone and plot, you need at least a periodic connection to the network. Without the application, scales show only current weight, but do not preserve history.
Why do we have different weights in the morning and evening?
This is normal. The difference is caused by food and water intake during the day, and by moisture loss through breathing and sweating. Always use fasting morning measurements to track progress.
What is the maximum weight of Xiaomi?
The maximum load is 150 kg. If this value is exceeded, a warning will appear on the screen, and the accuracy of body composition measurements is not guaranteed. The minimum weight for activation is about 5 kg.
