Xiaomi Mi Body Composition Scale 2 (model) XMTZC05HM) So, alone is the standard scenario that most users understand immediately after being pulled out of the box, but once a second family member is involved in the weighing process, chaos begins: The data gets mixed up, the graphs lose their meaning, and the app stops correctly mapping each user's progress, and the problem is not the hardware of the device, but the logic of the software, which by default tries to tie all the measurements to a single account.
For Xiaomi Mi Scale 2 to work correctly for two or more people, you need to properly configure the profiles in the application and understand the principle of data transfer via Bluetooth. Unlike simple mechanical scales, this model analyzes the body composition using a bioimpedance method, which requires accurate identification of the user at the time of measurement. If you want the scales to automatically recognize who has stood on them, or just do not want to manually reassign the recordings, follow the detailed instructions below.
The key is to use a single Xiaomi Account on different smartphones or add family members as users within the same app. The most reliable way to share data is to create separate profiles within the Zepp Life app (formerly Mi Fit) and use the Guest Mode feature or manually switch before weighing in, avoiding synchronizing your husband’s weight with your wife’s profile and vice versa.
The principle of working weights with multiple users
The Mi Body Composition Scale 2 smart scales don't have a built-in profile screen, so the whole logic of the data distribution lies on the shoulders of the smartphone and the app. When you step onto the platform, the scales measure the weight and, if Bluetooth is on, try to connect to the phone. If the connection is established, the app determines which profile is active at the moment and records the data there.
There are two main scenarios for family use: the first scenario assumes that each family member has a smartphone with an app installed, but they are all tied to the same Xiaomi ID account. In this case, the data will be synchronized between devices, which may be convenient for general control, but creates confusion in the progress schedules. The second, more correct scenario is the use of the Family feature or individual profiles within the Zepp Life application.
⚠️ Attention: Libras cannot automatically determine who is standing on them based on weight alone, if the difference between users is minimal.If a man weighing 80 kg and a woman weighing 78 kg use a scale without prior preparation, the data may be written incorrectly.
The system needs to be able to create and configure profiles for each user in the app, and the device algorithm remembers the last few measurements and tries to match the current weight with the history of a particular profile. If you just signed up, the scales will learn to recognize you, so the first 5-10 weigh-ins are best done when you are actively attached to your phone.
Preparation of the Zepp Life app for the family
The main tool for weight management is the Zepp Life app (formerly known as Mi Fit), which is where the magic of data separation takes place, and before you start using it, you need to make sure that you have the latest version of the application installed, since in older versions the profile functionality may not work properly.
The first step is to create a basic profile. The person who will be the device administrator (usually the person who bought the scale) must add the scales to the application through the Profile → Add the device → Libra menu. After pairing, you need to enter exact data: height, age and gender. These parameters are critical for calculating the percentage of adipose tissue and muscle mass.
Then you need to add a second user. In the Zepp Life app, go to Profile and find the option to manage family members or guest mode. Depending on the version of the interface, this can be called "Managing the Family" or just creating a new profile. It is important to fill in all the fields as accurately as possible, because this depends on the error of calculations.
- 📱 Make sure that both smartphones (if there are two) have the same version of the Zepp Life app installed.
- 👤 Create separate profiles for each user within the same app account.
- 🔗 Link the scales to the main account, secondary users will see the data through general synchronization or guest access.
- 📏 Enter accurate anthropometric data: height, age, body type.
Once you have the profiles set up, the system is ready to be calibrated, so don't be in a hurry to analyze the results, let the algorithms assemble the primary database for each family member.
Step-by-step: weighing two people
Weighing, when you have two or more people in your home, requires a habit, and you need to follow a sequence to keep the data from getting mixed up, and the most reliable method is to use Guest Mode or manually switch an active profile before each measurement.
Consider a scenario where a husband and wife use scales, a wife picks up her phone, opens Zepp Life, makes sure her profile is active, stands on the scales, waits for the measurement to be completed, the data is synchronized with her profile, then she walks away, picks up the husband's phone and repeats the procedure, but after making sure that the app (or guest mode) has selected a male weighing.
What if the scales are stuck on one profile?
If the scales automatically sent the data to the wrong user, don't panic. Go to the measurement history in the application, find the error record, click on it and select the option "Edit" or "Change User". You can reassign the record to the correct profile and the statistics will be updated automatically.> There is also the possibility of using the scales without constantly opening the application, but this requires care. Xiaomi Mi Scale 2 scales are able to store in memory up to the last 10 measurements if Bluetooth was active at the time of weighing. The next connection of the smartphone, the data will be lined up and distributed by the temporary profile, however, if both of the first users are placed on the same phone. Action User 1 (Major) User 2 (Guest/Family) Including the scales Automatically on the occurrence Selecting profile Auto (main account) Selection is required in the application Synchronization Instantly via Bluetooth When active application Saving history In personal profile In the profile of a family member If the phone is in another room, the scales will write the data into internal memory, but will not be able to immediately determine the profile, which can lead to errors in synchronization. The accuracy of the calculations of the composition of the body directly depends on the quality of the entered in the profile Comdy, the second calculation is calculated by the weight of the user. To set up the second user, go to Profile → Profile settings. Here you need to specify not only height and age, but also physical activity level. This affects the calculation of basic metabolism. For older people or children (if the scales support their use, usually from 5-6 years old), the settings may differ. Particular attention should be paid to the “body type” parameter or similar settings in the extended menu. Some versions of the application allow you to choose the goal: “Weight loss”, “Maintension” or “Masset Gain.” This affects what recommendations the artificial intelligence of the application will give after each weighing. If one of users is a professional athlete with a large weight, or an overweight algorithm can show a muscle weight. In such cases, it is recommended to use “Athlete Mode” (if available in your version of the firmware scales) or simply ignore the fat percentage, focusing on the dynamics of changes and measurements with centimeter tape. Solving frequent synchronization problems Despite the simplicity of the device, users often face problems when using the scales together. The most common complaint is “the scales do not see the second phone” or “the data goes wrong there.” Often the reason lies in the peculiarities of Bluetooth in the background on modern smartphones. If the scales are no longer synchronized with the second device, try to do the following: first, make sure that the application has the second one’s Bluetooth module, especially the necessary for the Bluetooth to access to the second one, the phone is not have access to the Bluetooth module. 🔄 Reconnect the scales: Remove the device from the Bluetooth list in the phone’s settings and add again through the app. 🔋 Check battery power: weak batteries can cause unstable operation of Bluetooth module. 📱 Update the app: Make sure both users have the latest versions of Zepp Life installed. 🚫 Turn off energy saving: forbid the system to “kill” the application process in the background. ⚠️ Warning: Don't try to connect the scales directly through Bluetooth Android or iOS system settings. The pairing must be done exclusively within the Zepp Life app, otherwise the body composition function won't work. To do this, there is a small reset button on the bottom panel of the device (where the battery compartment is. Press it with a paper clip, and then the scales go back to the factory settings and they need to be added to the application again as a new device. Measurement accuracy and influence factors When using scales by two people, it is important to understand that many external factors affect the accuracy of measurements. The bioimpedance analysis used by the Xiaomi Mi Scale 2 scales lets a weak electric current through the body. The resistance of tissues to this current depends on the content of water, muscle and fat. Day time and hydration of the body play a key role. In the morning, after waking up and visiting the toilet, the scales will show the most accurate and comparable results. If one person is tested in the morning, the same time after dinner. The readings are also affected by the temperature of the floor and the surface on which the scales are standing, and carpeting or soft linoleum can distort the readings of pressure sensors, for two users this is especially important: If one is on a scale on a tile and the other is on a carpet, the difference in readings can be significant, even if the actual weight is the same. In addition, you should consider the condition of the feet. Dry skin of the feet increases resistance, which can lead to a decrease in the percentage of muscle mass. In cold seasons, when the skin is dry, readings may differ from summer ones.Rub the scale platform with a dry cloth between uses by different people to ensure good contact.Frequently asked questions (FAQ) Can you use Xiaomi Mi Scale 2 scales without a smartphone? Yes, scales will show weight on the built-in display even without a phone. However, body composition data (fat, muscle, water) and measurement history are only available when synchronized with the application. Without a smartphone, scales work like regular electronic scales. How many users can use the same scales at the same time? Technically, scales have no limit on the number of users, since they simply transmit data. The Zepp Life app imposes restrictions, but within the same family (5-10 people) there are usually no problems with separating profiles. The main thing is to keep profiles correctly. Why do scales show different weights when weighing again? Small discrepancies (50-100 grams) are normal for any weights. If the difference is large, make sure that the weights are on the weights are equal at the weights, also on the surfaces. Do you have to open the app to a second user each time? It's advisable to keep the app running or active in the background. If the scales can't connect to the phone at the time of weighing, they'll store the data in internal memory and give it back on the next successful connection, but the risk of misallocation of profile increases.
