Integrating smart gadgets into the Apple ecosystem is not just a trend, but a real necessity for those who monitor their health. Owners of Xiaomi devices often face the question of how to make the budget but functional scales of the Mi Body Composition Scale with the iOS operating system.
The main bridge between your iPhone and the weights is the Mi Fit app or its more modern counterpart Mi Fitness. It is through this software that the initial configuration, calibration and transfer of data on weight, percentage of fat, muscle mass and water occurs. Without the use of official or certified third-party software, the scales will only work in the mode of displaying current readings on the display, losing all its “smart” functionality.
It is important to understand that the stability of the connection depends not only on the version of the application, but also on the privacy settings of the smartphone itself. iOS is known for its strict security policy, so the system needs to explicitly allow access to Bluetooth and the local network. If you ignore these steps, the scales can be displayed in the search, but will not transmit data, which will cause the user to be puzzled.
Preparation of equipment and preliminary actions
Before you start the pairing process, you need to make sure that all the components are ready to work. First of all, check the charger in the scales themselves. Usually, a standard CR2032 battery is included, but if the device has been in storage for a long time, its charge may not be enough for a stable connection using Bluetooth Low Energy protocol.
The second critical point is to update your smartphone operating system: Modern versions of Mi Fitness applications require iOS versions at least 13.0 to work correctly. Outdated versions of iOS may not support the necessary encryption libraries that Xiaomi uses the data transfer protocol.
- 📱 Make sure your iPhone is Bluetooth enabled and it is active in the control center.
- 📶 Check for a stable Wi-Fi connection for initial user profile downloads.
- 🔋 If the scales are new, remove the insulation film from the battery compartment, if any.
Xiaomi is currently actively transferring users to the Mi Fitness platform, so the old Mi Fit may require updating or migrating data. download the application only from the official Apple store to avoid malicious copies.
⚠️ Warning: Don't try to connect scales through the standard Bluetooth settings menu in iOS. They won't appear there as an audio device or keyboard. The pairing takes place exclusively within the app.
Installation and configuration of the Mi Fitness application
Once you download the Mi Fitness (or Mi Fit) app, you need to create an account or log in to an existing one, which is a must, as all your body data is stored in the Xiaomi cloud and linked to a specific user ID, and without an account, the scales will not be able to determine who the weighing belongs to.
During the initial setup, the app will request a number of permissions, especially the Local Network, which allows the app to search for Xiaomi devices on your home Wi-Fi network and transmit weather or time data if the scales have such a feature, and to refuse this right can lead to synchronization errors.
Then you add a device. In the application interface, you go to the Profile or Device tab and click Add Device. The system will tell you to select a category — in this case, Libra. The application will start scanning the surrounding space for BLE signals.
For the profile to work properly, it is important to enter accurate anthropometric data: height, age and gender. Algorithms for calculating body composition (for example, visceral fat) are based on bioimpedance analysis, where height is a critical variable, and an error in this data will lead to incorrect calculations, even if the scales show the correct number of kilograms.
The process of pairing the scales with the iPhone
The most important step is to connect directly, and you can stand on the scale with one foot to activate the screen, but don't capture the weight completely. At this point, the scale display can flash a Bluetooth symbol or display the status of "waiting." The app on the phone at this point should detect the device.
Once the scales are found, a pairing request will appear on the iPhone screen, pressing “Plug in” or “Bind,” at which point confirmation may be required through a code that will appear on the scale display, although in most Mi Body Scale 2 models this step is automated.
Once you've successfully linked the scales, they give you a profile, and if you have multiple people using the scales, the system will suggest creating profiles for each family member, and this is done through weight recognition: if the person's weight is more than 3-5 kg different from the already known profiles, the scales will suggest you create a new profile or choose an existing one.
| Model of weights | Type of connection | Support for iOS | Annex |
|---|
| Mi Body Scale 1 | Bluetooth 4.0 | Yes. | Mi Fit |
| Mi Body Scale 2 | Bluetooth 4.0 BLE | Yes. | Mi Fit / Mi Fitness |
| Mi Smart Scale 2 | Bluetooth 5.0 | Yes. | Mi Fitness |
| Xiaomi Scale 2 | Bluetooth 4.0 | Yes. | Mi Fit |
It's important to wait until the synchronization is over. After weighing, the data doesn't come in instantly, it needs time to process in the cloud and transfer to the phone, which usually takes 5 to 15 seconds after you've left the scale.
What to do if the scales are not there?
Make sure the scales are not connected to another phone. Xiaomi scales can only remember one active connection to set up. If they were tied to another account, they need to be untied in an old app or reset (usually by removing the battery). Also try to approach the scales closely, as the range of BLEs when initially paired can be limited to 1-2 meters.> Integration with Apple Health (Health) One of the main goals of iPhone owners is to centralize health data. To see your weight in the native Health app (Apple), you need to build a single file from the application, Xiaomi adds weight to the application, and build a single file from the application. Select the Apple Health logo, and the system will redirect you to the iOS system settings, where you need to confirm access, and the access menu will allow the app to record weight and body composition. You can only allow the Write category, not just Reading, and if you only allow reading, the scales will work, but the data won't get into the Health app». 🍎 Open the Health app on your iPhone. 👤 Click on the profile avatar in the upper right corner. 🔗 Select “Apps” from the list of devices and services. ✅ Make sure that all weight categories are included for Mi Fitness, and that the data will be synchronized automatically with each weighting after setting up, but you should consider the possible delay. Sometimes you need to open the Xiaomi app and pull the list down for a forced update so that the data goes to Apple Health. Smart scales measure not only body weight, but using bioimpedance analysis technology, they pass a weak, imperceptible electric current through the body. Tissue resistance (impedance) allows algorithms to calculate the percentage of fat, muscle, water and bone mass. In the appendix, each indicator is evaluated. For example, visceral fat is fat surrounding internal organs. Excess fat is more dangerous than subcutaneous fat. 9, a higher 14 Xiaomi scales are quite accurate in tracking the dynamics of this indicator» (BMR) It shows how many calories your body is wasting at rest, which is useful for calculating your daily intake, but it's worth remembering that the calculations are estimates and may differ from medical devices. 2-3%. ⚠️ Attention: Bioimpedance analysis is not recommended for people with pacemakers, and although current is minimal, electronics manufacturers are reinsuring themselves and adding this restriction to the instructions. To get the most accurate body composition data, it is best to weigh in the morning, on an empty stomach, after going to the toilet and before drinking water. During the day, the body retains water, which can distort the percentage of fat and water, making the charts in the application “jump”. Despite the simplicity of the procedure, users often face technical difficulties, and the most common problem is that the scales are visible in the application, but not connected. Often this is solved by completely removing the application, rebooting the iPhone and reinstalling the software from scratch». This means that the scales are trying to connect to another family member's phone or lost communication with the previous device, in which case it helps to reset the scales (take out and insert the battery) and clean the Bluetooth list in the iOS settings (forget the device, if it is there). If the data is not synchronized with Apple Health, check the region of the Xiaomi account. Servers in different countries can work at different speeds or have restrictions. Switching the region in the application settings (without changing the account) sometimes helps to establish communication with Apple servers. Problem Possible cause Libra solution not included Cell battery or oxidized contacts Replace CR2032, clean contacts with alcohol No connection with iPhone Bluetooth system Reboot iPhone, recheck resolutions Wrong percentage of fat Dry feet or thick mat Lightly moisten feet, remove the mat under the scales It is also important to monitor the surface on which the scales stand. Linoleum, tiles or hard wooden floor - ideal bases. Soft carpets or fuzzy coating absorb some of the pressure and distort the readings of the units, for example, the applications of the use of the sensors, which can improve the possibilities of the measurements. The default is often kilograms, but it's easy to switch to pounds in profile settings if you need it for compatibility with other services, and Guest Mode is available, and if friends come to you and want to weigh in, they can do so without creating a profile. The data will be recorded as “Guest” and will not be mixed with your statistics, but will not be analyzed in depth, as the height and age of the guest are unknown. For advanced users, integration with Google Fit (via third-party application bridges) is available if you plan to switch to Android in the future. Data export in format CSV It allows you to keep your own archives in Excel, which is convenient for building complex dynamic graphs. Can you use scales without the Internet? Yes, scales can work without an active Internet connection at the time of weighing. The data is stored in the internal memory of the scales (usually up to the end of the period). 10-30 Once the phone with the application running is close to the Bluetooth, the story syncs. However, the Internet is required to set up the initial setting. Why do scales show different weights on different surfaces? Xiaomi scales use strain gauges in four corners. If the surface is soft (carpet, carpet), the legs of the scales are bent unevenly, and some of the weight goes to the floor, bypassing the sensors. This is a physical feature of all electronic scales, not a defect of a particular model. How many users can use the same scale? Technically, the scale can store data up to 10-16 Users (depending on the model and firmware version). Mi Fitness allows you to create an unlimited number of profiles, but only those whose weight falls within a given range will be active for automatic recognition. Using smart scales in conjunction with the iPhone opens up great opportunities for health control. Proper setting, regular weighing in the same conditions and attentive attention to the recommendations of the application will help you achieve the desired results faster.
