Connecting Xiaomi scales to the Health app: full instruction with error solutions

Xiaomi’s smart scales are not just a weight measurement device, but a full-fledged body composition analyzer that syncs with the Mi Home and Mi Health ecosystem (now Zepp Life), but many users face difficulties when first connecting: the device does not find the scales, the data is not stored, or the application gives an error “failed to connect”, this article will help you understand all the nuances from preparing devices to solving typical problems.

We will look at the current models of weights (Mi Smart Scale 2, Mi Body Composition Scale 2, Xiaomi Smart Scale 3), the features of their synchronization with Android and iOS applications, and give recommendations for setting up a profile for maximum measurement accuracy. If you have tried to connect the scales, but nothing has come out – at the end of the article there is a section with the diagnosis of errors and ways to fix them.

What Xiaomi scales support synchronization with Mi Health

Not all Xiaomi smart scales are compatible with Mi Health (now Zepp Life) app, here's the current list of supported devices for 2026:

• 🔹 Xiaomi Mi Smart Scale 2 - Basic model with weight, BMI, fat and muscle measurement (up to 150 kg support).
• 🔹 Xiaomi Mi Body Composition Scale 2 - Extended version with analysis of 13 parameters (including bone mass and water level).
• 🔹 Xiaomi Smart Scale 3 – a new model with improved sensors and support for Bluetooth 5.0.
• 🔹 Xiaomi Mi Body Fat Scale (first generation) – outdated model, but still supported.

Xiaomi scales do not work directly with third-party applications (such as Google Fit or Apple Health) and are first synchronized with Mi Health/Zepp Life, and from there can be exported to other services through integrations.

If your model is not listed, check its compatibility on the official Xiaomi website or on the product card on AliExpress/Amazon. Outdated devices (for example, Mi Scale 1) may not support the latest versions of the application.

Preparing for connection: what to do before synchronization

Before you start connecting, follow a few mandatory steps, which will save time and help avoid typical errors:

1. Update the firmware of the scales (if they have been used before). To do this, open the Mi Home app, find the device in the list and check for updates in the Settings → Firmware Update section.
2. Install the latest version of the app. Download Mi Health (or Zepp Life) from official stores: 📱 Google Play (Android) 🍎 App Store (iOS)

Bluetooth Low Energy (BLE)

Important for iOS: on iPhones, after connecting the scales, you may need to manually allow access to Bluetooth in the application settings (Settings → Mi Health → Bluetooth).

Step-by-step: how to connect Xiaomi scales to Mi Health

Now, the connection process itself, and the instruction is universal for all supported models, but there may be minor differences in the interface of the application.

Step 1: Adding the device to Mi Health

1. Open the Mi Health app (or Zepp Life) and log in to your Xiaomi account.

2. Click on the + icon (usually in the upper right corner) or go to Devices → Add the device.

3. In the category list, select Libra or type the model name in the search bar (e.g. Mi Smart Scale 2).

Step 2: Activation of the scales

1. Turn on the scales by pressing them with your foot or the power button (if any). The display should show a "0.0" or flashing indicator.

2. Wait for the sound signal or vibration – this means that the scales are ready to pair.

3.In the app, click “Connect” and confirm pairing on your smartphone (entry may be required). PIN-code, usually 0000 or 1234).

Step 3: Set up a user profile

After successful connection, the application will offer to create a profile:

• 👤 Indicate gender, age, height and initial weight (this data affects the accuracy of measurements).
• 📅 Choose a goal: losing weight, maintaining shape or gaining weight.
• 🔄 Set up automatic synchronization (it is recommended to enable).

💡

If the scales don’t determine your weight at the first weigh-in, reset them to factory settings: press and hold the power button for 10 seconds until the display blinks.

Critical detail: If you share scales with other family members, add their profiles in the app through the Family section, which will allow the device to automatically recognize users by weight.

Note: Wi-Fi-enabled models (such as the Xiaomi Smart Scale 2 Pro) can sync without a smartphone, but you will still need Mi Health to set up the first setup.

Typical errors and their solutions

Even with the right connection, users often encounter problems, and here are the most common errors and ways to fix them:

⚠️ Note: if the scales are connected but do not transmit data to the application, check whether the antivirus or energy saving mode blocks the work of Mi Health.

Error: “I couldn’t connect to the device”

• 🔋 Check the battery power in the scales (if the model is battery-powered). Charging below 10% may interrupt synchronization.
• 📱 Reboot your smartphone and scales (remove the batteries for 30 seconds if the model is on the phone). AAA).
• 🔄 Update the firmware of the scales through Mi Home (if available).
• 📡 Make sure the distance between the weights and the phone is less than 5 meters (walls and interference reduce the range of the device). BLE).

Error: Data is not saved or reset

• 👤 Check that the correct user profile is selected in the application.
• 🌐 Enable automatic synchronization in the Mi Health settings (Settings) → Synchronization of data).
• 📥 Update the app to the latest version (outdated versions may not support new weight models).

Mistake: Scales are not included

If the scale display does not respond to pressing:

• 🔋 Replace batteries (even if they are new, factory marriage is possible).
• 🔌 Check the contacts of the battery compartment for oxidation.
• 🔄 Reset settings: Press and hold the power button for 15 seconds.

If nothing helps, contact the Xiaomi service center - a hardware defect is possible.

How to improve the accuracy of measurements

Xiaomi’s smart scales use bioimpedance analysis (BIA) technology, which can yield errors when used incorrectly. Follow these tips for maximum accuracy:

• ⏰ Weigh yourself at the same time (better on an empty stomach in the morning).
• 🚿 Before weighing, wipe your feet dry - moisture distorts fat and muscle indicators.
• 👟 Stand on the scales with bare feet, evenly spreading the weight.
• 📵 Don’t hold a smartphone or metal objects – they affect bioimpedance.

For analysis of the dynamics, use weekly or monthly data, not single measurements. The error of individual weighing can reach ± 0.5 kg for weight and ± 3% for fat mass.

💡

For the most accurate results, weigh yourself on an empty stomach and after using the toilet. Morning measurements give the most stable dynamics.

If you care about professional metrics (for example, for sports purposes), consider buying certified medical scales. Xiaomi models give a good rough estimate, but do not replace laboratory tests.

Exporting data to other applications (Google Fit, Apple Health)

By default, Mi Health doesn’t sync with Google Fit or Apple Health, but there are workarounds:

For Android (Google Fit)

1. Open Mi Health and go to Profile → Settings → Sync with other apps.
2. Select Google Fit and log in through your Google account.
3. Allow access to data on weight, steps and activity.

For iOS (Apple Health)

There is no direct synchronization on iPhones, but you can use third-party bridge applications, for example:

• 📱 Health Sync (paid but reliable).
• 📱 Apple Health Importer (Free version with restrictions).

⚠️ Note: When exporting data to Apple Health, certain parameters (such as bone mass or viscosity) may not be portable due to limitations. API. Check supported metrics before setting up.

You can also export data manually through the CSV file:

1. At Mi Health, go to Profile → Data Export.
2. Select a period and confirm the export.
3. The file will be sent to your email or saved to the cloud.
