The Chinese giant’s smart gadget owners often face the need to integrate all devices into a single ecosystem. When weight control is on the agenda, many users are lost in the abundance of software solutions. Xiaomi’s scale app is not just one program, but a network of interconnected services that can confuse even an experienced techno enthusiast. Choosing the right software is critical, because it is responsible for calibrating sensors and measuring adipose tissue accurately.
The challenge is that different scale models may require different platforms to set up the first setup. Some devices run on the old Mi Fit, others have already moved to Zepp Life, and still others require a dedicated Mi Body Composition. A mistake in choosing can lead to the gadget simply not syncing with the phone, leaving you with no valuable statistics. In this article, we will find out what software your model needs.
We will take a detailed look at the installation process, Bluetooth 5.0 pairing, and family profile settings. You will learn why you sometimes have to use third-party utilities for full functionality and how to avoid conflicts between different versions of firmware. Xiaomi's current scales require activation via Bluetooth before the first weighing, otherwise they will only work in the weight display mode without data transfer.
Official Application Names and Their Differences
The first thing that you need to understand is that there is no single application for all devices. The Xiaomi ecosystem evolved in an evolutionary way, which led to separation of functionality. The Mi Fit app has long been the main control center for most wearables and scales. However, in 2021, Huami (the hardware manufacturer) rebranded the Mi Fit app and renamed it Zepp Life. It's a confusion, but functionally it's the same program with an updated interface.
More advanced models, such as the Mi Body Composition Scale 2 or Xiaomi Smart Scale 2, often require an additional plugin or a separate application called Mi Body Composition. It is necessary for deep bioimpedance analysis. Bioimpedance analysis allows you to measure not only weight, but also percentage of muscle mass, bone tissue, visceral fat and water level in the body. Without this specialized software, scales can only transmit basic data.
- 📱 Zepp Life (formerly Mi Fit) is a basic application for synchronizing, storing history and customizing user profiles.
- ⚖️ Mi Body Composition is an auxiliary application that acts as a “bridge” for transferring detailed body composition data to the main profile.
- 🏠 Mi Home is a versatile smart home platform that can also display scale data if added to the smart home ecosystem, but it is less commonly used for initial weight adjustments.
It’s important to note that installing all three apps isn’t always mandatory, but for the full functionality of the Mi Body Composition Scale 2, the Zepp Life bundle plus the scale plugin is the most reliable. Users often ignore the need to install the second component, wondering why the 13 health indicators don’t work. The data protocol in new models has become more complex, requiring more powerful computational algorithms that are built into specialized software.
⚠️ Note: Do not try to connect scales directly through the standard Bluetooth menu settings Android or iOS. the pairing must occur exclusively inside the application interface, otherwise the device will block the transfer of data about body composition.
Step-by-step instruction for connecting the scales to the smartphone
The setup process may seem simple, but requires a strict sequence of actions. Disruption of the order of steps often leads to pairing errors. Before you start, make sure that the smartphone is enabled geolocation (GPS) and Bluetooth. This is the system requirement of Android for working with IoT devices. Without the geolocation enabled, the application simply will not see the scales in the list of available devices.
First, download and install the Zepp Life app from the official Google Play or App Store. Sign up or log in to your Mi Account. Then go to your profile and select to add the device. Unlike the older versions, where scales searched for themselves, now often need to scan. QR-code on the bottom of the device or select a model from the list manually. QR-The code contains a unique device identifier necessary to protect user data.
☑️ Checklist before connection
Once the scales are found, stand on them with one foot to activate the sensors. The screen should light up and the pairing process will begin. If you use a model with body composition analysis, the application will offer to download an additional plugin. You agree to install. Once the process is complete, the scales will automatically transfer the accumulated data to the cloud. It is important for the algorithms to correctly enter your data: height, age and gender. The accuracy of the calculations depends on the correctness of these input parameters.
Profile setting and bioimpedance analysis
One of the key features of smart scales is the ability to keep statistics for several people. In the Zepp Life application you can create up to 16 profiles. The system automatically recognizes the user based on weight and percentage of fat and muscle mass. However, for the initial calibration, each family member must weigh "manually" by selecting his profile in the application before stepping on the platform.
Bioimpedance analysis works by passing through the body a weak electric current that is intangible to humans. Tissue resistance (impedance) allows you to calculate the composition of the body. Fat tissue conducts current worse than muscle tissue because it contains less water. That is why it is important to stand on the scale barefoot and preferably with wet feet, if the skin is dry, to improve contact with electrodes.
| Parameter | Description | Impact on calculations |
|---|---|---|
| Growth | Enter once when creating a profile | Critical for calculating BMI and fat percentage |
| Age. | Updated automatically or manually | Affects metabolic age and weight norms |
| Paul | Male/female | Determines the distribution of fat and muscle tissue in normal |
| Type of body build | Automatic or manual selection | Adjusts calculation formulas for athletes or seniors |
You can set the app to "Guest Mode" if you don't want to save the temporary user's data, you can also use automatic child recognition, you need to specify the appropriate age in your child's profile, and the algorithms for children are different from adults, because the body is in the growth stage, and standard formulas can give errors.
The secret to accurate weighing
Solving Connection and Synchronization Problems
Despite the debugging of Bluetooth Low Energy (BLE) technology, users often face problems: the scale may not be visible to the phone or break the connection in the middle of the weighing. Most often, the problem is that the device remained “hung” in the Bluetooth memory of the previous phone or system, in which case you need to go to the Bluetooth settings of the smartphone, find the scales there (usually Mi Body Fat Scale or Xiaomi Scale) and click “Forget the device” or “Unpatch pairing”.
Another common cause is batteries that are discharged. Even if the screen lights up, the voltage may not be enough to power a Bluetooth module that consumes more power when the data packet is transmitted. Use only high-quality alkaline batteries. Salt batteries, often included in the sample, can quickly lose charge and cause unstable operation.
- 🔄 Bluetooth Reboot: Turn off and turn on Bluetooth on your phone, then restart the app.
- 📍 Geolocation: Make sure that the location permission for the application is in "Always" or "When using" mode".
- 🔋 Energy saving: Check if the app is not worth the list of limited background processes. add it to battery exceptions.
If the scales show weight but don't transmit body composition, check which application you're measuring in. The measurement start should be from the Profile -> Weight -> Weight. If you just stand on the scale, they can write the weight to internal memory, but not initiate the transmission of a detailed report. The internal memory of the scales is limited and stores the last user's data until the time of synchronization.
⚠️ Note: If the scales show the "Err" symbol or flashing screen, this may mean overload (exceeding 150 kg) or, conversely, too low a weight (less than 5 kg) that the device cannot fix.
Alternative applications and third-party software
Xiaomi’s official software is functional, but not always convenient for everyone. Some users prefer more advanced graphics, integration with other health services, or just a different interface design. For these cases, there are third-party apps that can read data from Xiaomi’s scales. One of the most popular is Notify for Mi Band (now Notify & Fitness), which allows you to display notifications on the scale (if the model supports the screen) and has advanced analytics settings.
There's also Scales+ or Weight Watchers, which can import data from Google Fit or Apple Health, which in turn is uploaded by the official Zepp Life app. This creates a chain: Libra → Zepp Life → Google Fit → Third-party application, which allows you to use specialized software for nutritionists or trainers without giving up your own scales.
However, it is worth remembering the risks of using unofficial software. Third-party developers may not have time to update their algorithms for new versions of the firmware scales. The data encryption protocol sometimes changes, and the third-party application may not see the scales after updating firmware. In addition, transferring data to third parties, you should be confident in the developer's privacy policy.
💡
Use the Zepp Life + Google Fit bundle for maximum compatibility. Set up an automatic export of data from Zepp to Google Fit, and then any application that works with Google Fit will be able to see your weight statistics.
Integration with other services and smart home
Xiaomi's ecosystem allows you to not just collect data, but also use it to automate. Through the Mi Home platform or scripts in Apple HomeKit (with the appropriate gateway), you can create chains of actions. For example, when you reduce weight to a certain mark, the smart light in the bathroom can change color to a holiday, or the speaker can voice a motivating message.
For health-care users, integration with Google Fit and Apple Health is important. In Zepp Life, you need to find the Add Accounts section and log in to Google or Apple. After that, all weighings will automatically be duplicated into the health system storage, which is useful if you use another brand smartwatch or a fitness tracker that also writes data to these services — all the statistics will be collected in one place.
It is important to check your sync settings periodically. Sometimes, after updating your phone's operating system (iOS or Android), your health data permissions may be reset. If you notice that new weigh-ins don't appear in the overall schedule, the first thing you do is check the connections between the apps in the Services and Subscriptions or Add Accounts menu.
💡
Main bundle for full functionality: Install Zepp Life to manage your device, connect export to Google Fit/Apple Health for reservation, and use third-party apps only for advanced analytics if the baseline is missing.
