How to connect a second person to Xiaomi weights: all ways + error solving

Xiaomi's smart scales are not just a weight measurement device, but a full-fledged body composition analyzer that can store data from multiple users. However, many people have difficulty adding a second family member: the app does not see the scales, the data is confused, or the profile is simply not saved. In this article, we will discuss all the current ways to connect a second user on the Mi Body Composition Scale 2, Smart Scale 2 and others, and solve typical problems.

It's important to understand that the process depends on the firmware of the scales and the version of the application (Mi Fit, Zepp Life or Mi Home). We tested the instructions on the latest versions of the software (2026) and took into account changes in the synchronization algorithms. If you have tried to add a user, but nothing worked, check the error section at the end of the article.

What Xiaomi scales support multiple profiles

Not all Xiaomi smart scales can distinguish users automatically, but here is a list of devices that support multiplayer:

• 🔹 Xiaomi Mi Body Composition Scale 2 – up to 16 profiles, weight recognition with error ±3 kg
• 🔹 Xiaomi Smart Scale 2 – up to 10 profiles, requires manual selection in the application
• 🔹 Xiaomi Mi Smart Scale (first version) – only 1 profile, does not support multiple users
• 🔹 Xiaomi Mi Body Fat Scale – up to 8 profiles, recognition by IMC (mass index)
• 🔹 Redmi Smart Scale – up to 12 profiles, sync via Mi Fit or Zepp Life

If your model is not included in this list, check the specifications on the official website or in the instructions. For example, the 2016 Mi Smart Scale does not physically store the data of several people - only buying a new version will help.

Preparation before adding a second user

Before you start setting up, follow the mandatory preparatory steps:

1. Update the firmware of the scales. Go to the Mi Home app → select your scales → Device settings → Firmware update. Update for 2026 is 2.5.6 and higher.
2. Install the latest version of the app. Xiaomi will do the weights: 📱 Mi Fit (version 5.8)+) 📱 Zepp Life (version 6.3)+) 📱 Mi Home (for initial setup only)

Synchronize the data of the first user

If you’re using an iPhone, check the permissions for the app in Settings → Privacy → Health. Without access to Apple Health, syncing may not work properly.

Update the firmware of the scales to 2.5.6+

Install Mi Fit/Zepp Life with the latest version

Check the synchronization of the first user data

Disable VPN (can block Xiaomi servers)

Charge scales (if the charge level is below 20%, adding a profile may not work)-->

Method 1: Adding via the Mi Fit app (recommended)

This is the most reliable method for most models.

1. Open Mi Fit and go to Profile → Devices. Select your scales.
2. Click on the icon. ⚙️ Settings in upper right corner.
3. Select User Management (or Add Users in older versions).
4. Click Add and enter the second person's data: 👤 Name (e.g. “Maria") 📏 Growth (in cm) 🎂 Date of birth (to calculate metabolism) ♂️/♀️ Paul

Save the profile and ask the second person to stand on the scale.The app should automatically identify the new user by weight.

If the scales do not recognize the second user, try to stand on them together with the first person - this will reset the recognition algorithm.

💡

After adding a second profile, do a test weighing of both users in a row, which will help the scales "remember" the difference in weight and improve recognition accuracy.

Method 2: Set up with Zepp Life (for new models)

The Zepp Life app (formerly Amazfit) now officially supports Xiaomi scales. The instruction for it is slightly different:

1. Open Zepp Life and go to Profile → My Devices.
2. Select scales and click User Management.
3. Click + Add a family member and fill in the data (similar to Mi Fit).
4. After saving, ask the second user to stand on the scale. In the application, a notification of a new weighing will appear with a suggestion to assign it to a profile.

Zepp Life has an additional feature called Automatic Recognition, which analyzes not only weight, but also fat/muscle percentage.

1. Go to the weight settings.
2. Select User Recognition → Automatically.
3. Activate the option to Use Bioimpedance.

Method 3: Manually switch profiles (for older models)

If your scales do not support automatic recognition (for example, Smart Scale 2 without the latest firmware), you can switch between profiles manually:

1. Open Mi Fit and select the scales.
2. Before weighing, click on the user icon in the upper right corner of the screen with the scales.
3. Select the desired profile from the list.
4. Now you can stand on the scale - the data will be recorded under the selected user.

This is a tricky technique if you have multiple people using scales, but it's the only one that works for stripped-down versions of firmware. To make things easier, you can put the Mi Fit label on your smartphone's home screen.

⚠️ Note: On the Mi Smart Scale scales (first version), manual profile switching only works if they were added via Mi Home, not Mi Fit.

Typical errors and their solution

If the second user is not added or the data is confused, check these points:

• 🔄 Libras do not recognize the user: Make sure the weight difference between users is greater than 3 kg (for Mi Body Composition Scale 2). Reset the scales: hold the switch on 10 seconds until the indicator flashes. Check that the settings have AutoRecognition enabled.
• 📱 The app doesn't see the scales: Turn off Bluetooth on your smartphone and turn it back on. Remove the scales from the device list in Mi Fit and add them again. Check that the scales are charged (the indicator should burn green).
• 🔗 The second user's data is recorded to the first: Delete all profiles and add them again. Weigh in turn at intervals of 10 seconds to "train" the scales. Update the firmware of the scales to the latest version.

If nothing works, try an alternative app, such as Yoo Health (available on the App Store and Google Play) for Smart Scale 2, which sometimes better recognizes users.

⚠️ Attention: On Android 12+ Mi Fit background may be blocked. To fix this, go to Settings. → Annexes → Mi Fit → Battery → No restrictions.

💡

If the scales stopped recognizing users after updating the firmware, reset to factory settings: hold the button for 15 seconds until the red indicator flashes.
