Digital health gadgets have become an integral part of the smart home ecosystem, and Xiaomi devices are leading the way here due to accessibility and functionality. The initial activation process often raises questions among users accustomed to classic electronics, where it is enough to simply insert batteries. However, smart scales require synchronization with a smartphone to transfer body composition data, which makes the adjustment procedure more versatile.
Proper device configuration is critical to future measurement accuracy at the outset. Matching errors or ignoring surface requirements can lead to systematic error that will distort your progress statistics. In this article, we will detail all the preparation, software installation and calibration steps to make your measurements as accurate as possible.
The Mi Body Composition Scale and Mi Smart Scale 2 have their own unique features that you need to know before weighing them first. Understanding the principles of bioimpedance analysis will help you avoid common mistakes and get a complete picture of the state of the body.
Preparation for the first launch and unpacking
The first thing that a user faces after removing the device from the box is the need to remove the protective film from the battery compartment. Manufacturers often leave a dielectric gasket between the contacts and the battery to prevent self-discharge when stored in a warehouse. Removing the insulator is a must-do step without which the scales won't turn on even if you step on them with your entire body weight.
It is important to choose the right place to install the gadget. The surface should be absolutely flat, hard and dry. Soft carpeting, fuzzy mats or sloping floor will lead to incorrect readings of pressure sensors. The ideal option is considered tile, laminate or linoleum in the bathroom or hallway.
⚠️ Warning: Never use scales on soft surfaces such as carpet or (mattress) This will not only distort data, but can also damage sensitive strain gauges due to uneven load distribution.
Once installed on a flat surface, wait for the Mi logo or the readyness indication to appear. If the screen does not light up, check the polarity of the batteries installed. Often users confuse the plus and the minus, especially in models with vertical installation of batteries.
💡
Use only high-quality alkaline batteries. Salt cells can quickly discharge and leak, damaging the contacts of the device.
Installation and configuration of the Mi Fitness application
Without software, scales become a mass meter, losing their main trump card, body composition analysis. You will need to download the official application to work. Mi Fit was used before, but now the current version is Mi Fitness (formerly Zepp Life), which is available on Google Play and the App Store.
The process of registering an account is a must-do step, and you need to create a profile with real data like height, age and gender, and these parameters are used by algorithms to calculate the percentage of fat, muscle mass and water using bioimpedance analysis, and if you enter the wrong data, the calculations will be incorrect, regardless of the accuracy of the weights themselves.
After you log in to your account, go to the profile section and find the add-on button. QR-code located on the bottom of the scales, or select a model from the list. Make sure that the smartphone is enabled Bluetooth and geolocation, as Android requires permission to access the location to search BLE-device.
☑️ Pre-conjugation check
The process of pairing weights with a smartphone
Synchronization is done via Bluetooth Low Energy (BLE), which is power efficient. When you add scales to the app, a pairing code confirmation request will appear on your smartphone screen, and the matching of the numbers on your phone screen and the scale display ensures that you connect to your device, not your neighbor's.
In some cases, automatic search may not work the first time. If the app is long to turn the load indicator, try restarting Bluetooth on the phone or restarting the application itself. Also make sure the scales are not connected to another smartphone, as they can only transmit data to one active device at the time of measurement.
Once paired successfully, the device profile will display the current battery charge and firmware version, and it is recommended to check for firmware updates immediately, as new versions often contain corrections to weighing algorithms and improved connection stability.
What if the scales are not visible on the list?
Calibration and first weighing
The first weighing is the process of calibrating strain gauges to your individual settings. Stand barefoot on the platform, spreading the weight evenly on both feet. The feet should fit tightly to metal electrodes if your model supports bioimpedance measurement. Contact with electrodes is necessary to pass microscopic current through the body.
When you measure, you have to stand still, and any swaying, wall support, or hand holding can make a big difference, and the scales will first show you your weight, and then, within a few seconds, calculate the rest of the metrics that will be displayed in the app after you synchronize.
| Parameter | Description | Importance of contact |
|---|---|---|
| Weight. | Total body weight | Low (works in shoes too) |
| Percentage fat | Percentage of adipose tissue | High (contact required) |
| Muscle mass | Mass of skeletal muscle | High (contact required) |
| Water in the body | Percentage of liquid | High (contact required) |
For models without metal electrodes (weighing only), the contact of the stops is not as critical, but for Pro or Body Composition Scale models, it is a must. If you weigh in socks, you only get the weight data, the remaining fields will remain empty.
💡
For a full range of health data, be sure to remove your shoes and socks, ensuring that the skin of the feet is in direct contact with the metal plates of the scales.
Setting up user profiles and guest mode
One of the main advantages of the Xiaomi ecosystem is the ability to create up to 16 user profiles, which allows the whole family to use one device, and the application will automatically recognize the owner by weight and parameter ratio. To set additional profiles, go to the device settings in the application and select "Add family member".
When you add a new user, the system will ask you to enter basic anthropometric data. The more accurate you specify height and age, the more correct the identification algorithm will work. If the weight of two users is very similar, the system can confuse profiles, so in such cases it is recommended manually to choose the user in the application after weighing.
There's also a Guest mode that lets you weigh in without saving your history or linking to your profile, which is convenient if you have friends who want to just check your weight without creating accounts in your ecosystem, and the guest weighing data is not normally synced to the cloud.
⚠️ Note: For children under 16 years of age and people with pacemakers, the use of bioimpedance analysis (body composition measurement) is not recommended).
Solved problems and synchronization errors
Despite the reliability of the technology, users can run into problems, most commonly the "Device not found" or "Unable to connect" error, often due to the scales "sleeping" to save energy. Try knocking on the platform slightly or stepping on it to wake up the Bluetooth module before starting the search in the application.
Another common problem is that the readings are not consistent with the medical scales, and remember that home electronic scales have a margin of error, and their readings depend on the moisture of the skin, the time of day and the fullness of the stomach, and the most accurate results are obtained in the morning on an empty stomach, immediately after going to the toilet and before drinking water.
If the scales show an error of "Err" or "Lo", this signals an overload (exceeding 150 kg) or a discharge of batteries, respectively. In case of an overload error, do not panic, just remove the load. If the discharge indicator is on, replace the batteries with new ones, after wiping the contacts inside the compartment with dry cloth.
Why do weights show different weights throughout the day?
In conclusion, the right setup of Xiaomi smart scales opens up access to a powerful health monitoring tool, and regular weighing and analyzing trends in the app will help you achieve fitness goals more effectively.
