How to use Xiaomi smart scales for several people: full instruction

Modern health gadgets have become an integral part of the smart home ecosystem, and Xiaomi’s smart scales are leading the way here thanks to their affordable price and functionality. However, when more than one person lives in an apartment, there is a reasonable question about the correct distribution of data among users. Many owners mistakenly believe that the device automatically distinguishes people, but accurate statistics require a competent initial setup.

The bioimpedance analyzer that's built into the platform uses a low-voltage electrical current to pass through the body to determine tissue composition, which allows the system to distinguish muscle mass from fat mass, but identifying a particular person is often difficult. If you plan to use the device as a family, it's important to understand the algorithms of the Mi Fit (or Zepp Life) application, since it is the software that takes over the basic logic of distributing profiles.

In this article, we will go into detail about the process of creating separate accounts, setting up guest mode and methods for manually correcting recognition errors. The right configuration will allow each family member to see only their own weight dynamics without mixing the indicators with the data of the household, this is especially true for those who follow the progress of training or follow a diet.

The principle of user identification

The fundamental basis of the scales is bioimpedance analysis technology, which measures tissue resistance to electric current. When you stand on a platform with your bare feet, the electrodes read the data, which are then compared to the reference profiles in the application. The system tries to match the current weight and percentage of muscle/fats with the existing records in the database.

It's worth noting that automatic recognition doesn't always work perfectly, especially if users are of similar weight and build, and in such cases, the algorithm can assign measurements to an incorrect profile, which will distort the observational history, which is why primary calibration and clear division of profiles in the application are critical.

• 📊 The main parameter for primary identification is the current weight, recorded with high accuracy.
• 🧬 Secondary factors are the percentage of fat and muscle mass that are unique to each organism.
• 📱 Synchronization occurs only when the active Bluetooth connection of the smartphone with the scales at the time of weighing.

It's important to understand that scales don't have a built-in memory to store each user's measurement history separately, and the whole logic of separating resides data from the service cloud and locally on your smartphone, so if you change your phone or reinstall an app, the entire story will only be saved if you log in to the same account.

⚠️ Note: If two family members are almost the same weight (less than 0.5 kg difference), the system may continually confuse their profiles, in which case it is recommended to weigh in turn, waiting for the data to be synchronized with the first user's phone before weighing the second.

Preparation for setting up: creating profiles

Before you start weighing, you need to organize the space in the app correctly, and for each person who will use the scales, ideally, you need a separate Mi Account, which ensures complete privacy of data and no confusion in the statistics of training and health.

The sign-up process is simple: download the Zepp Life app (formerly Mi Fit) or Mi Fitness app on each user's smartphone. When you first start, the system will prompt you to sign in or sign up. Don't try to use the same login on different phones for different people, as this will result in all data being synchronized into one pile.

After signing up, each user must add their device to the app. Xiaomi scales support binding to only one main account, but allow you to share data or use the Guest mode. However, to fully work with the story, it is better that each user adds the scale as a new device to his profile, if the model allows, or uses the user change function.

The key is to get accurate anthropometric data, which means height, age and gender affect the composition of the body, and if you're given these parameters incorrectly, even accurate weight readings will not give you a good picture of health.

Step-by-step instructions for connecting several people

There are several scenarios for using weights by multiple people, and choosing the right one depends on your device model and the level of detail you want, and the most common method is to use the "User Change" function directly in the app before each weighing.

To implement this method, the first user must open the app, go to the scale profile and make sure that his account is selected. After weighing and synchronizing the data, the second user must take his phone, open the app and switch to his profile (if a shared family account is used), or simply weigh if the scales support multi-profile memory.

Newer models, such as the Mi Body Composition Scale 2, support up to 16 users.

1. Open the application on the smartphone of the first user.
2. Go to the weight settings and find the item "User Management".
3. Add a new user by entering their basic settings.
4. Repeat the procedure for the rest of the family.

⚠️ Note: When adding children under 12 years of age or pregnant women, it is recommended to disable the measurement of bioimpedance (tissue resistance) in the settings, since weak current may be undesirable, and calculation algorithms do not take into account the characteristics of children's or altered hormonal background.

Once the profiles are set up, the weighing process becomes automatic, the scales remember the latest parameters and try to assign the new weight to the nearest profile, and if the system is not sure, it will suggest that you choose the user manually on the smartphone screen.

Use of guest mode and temporary users

For situations when you have guests or are in a hotel where such scales are installed, there is a Guest mode, which allows you to weigh yourself without linking data to the main profile and without saving the history in the long-term memory of the application.

To activate this mode, it is usually enough to simply stand on a scale without opening the application or logging in. The device will measure the weight, but will not calculate the percentage of fat and muscle, because it does not know the parameters of the guest's body. On the scale screen or in the application (if it is open in the background) only the value of the mass will be displayed.

This is a convenient way to quickly check your weight without risking contamination with other people's data, but it is worth remembering that in some versions of the firmware, guest data can be temporarily stored in the "Last Dimensions" section, from where it is better to manually delete it.

*Note: The scale memory is limited and stores data only until synchronized with the main user's phone.

Solving problems with data recognition and confusion

Even when properly adjusted, there may be situations where the scales assign your weight to the profile of your spouse or child, often with sudden changes in body weight or if the users are in the same weight category, in which case user intervention is necessary.

If you notice an error, don't ignore it. Open the application, find the error in the history, and use the edit or delete function. In some versions of the software, you can manually reassign the measurement to another user from the profile list.

To minimize errors, try to weigh yourself at the same time of day and in the same clothes (better without them), which stabilizes the indicators and helps algorithms to identify the profile owner faster.

💡

For better identification, weigh yourself immediately after waking up, before breakfast and going to the toilet, which will give you the most stable "base" weight, which is easiest to distinguish from the weight of other family members.

Synchronizing data and working with the cloud

The final step in proper use is to ensure stable synchronization. Xiaomi's smart scales only transmit data to the smartphone when weighed, if the phone is nearby and the app is active. If you weighed and the phone was in another room, the data will be stored in the scale memory and transmitted the next time the app opens.

For family use, it is critical that each user syncs their data to their phone. If the scale is tied to the "main" phone, other users must either use the "Sharing" feature in the app or transfer the phone to the main user for synchronization, which is inconvenient.

Access to the device allows you to add scales to the second user's application without re-binding via Bluetooth, and to do this, in the main owner's application, you need to open the balance settings, select Access to the device, and send an invitation to the second user.

• 🔄 The main user retains full control of the device.
• 👨‍👩‍👧‍👦 Secondary users only see their data and history.
• 📲 Synchronization occurs automatically when the application is opened by any user.

⚠️ Note: Sharing only works if both users are in the same location (near the scales) or if the scales have a direct Wi-Fi connection (Wi-Fi-enabled models), which allows data to be transferred to the cloud without a phone.

💡

The ideal scheme for a family: one “owner” of the scale, which shares access to the rest of the family through the “Access to the device” function in the Zepp Life or Mi Fitness application.
