Connecting Xiaomi scales to the Honor smartphone: full instruction with error solutions

Why Xiaomi Libras Can't See Honor Phone and How to Fix It

Xiaomi Smart Scale (Mi Smart Scale Series) 2, Mi Body Composition Scale 2 Xiaomi Smart Scale 3) Designed for synchronization with mobile devices via Bluetooth Low Energy (BLE). However, users of Honor smartphones, especially models of Magic UI or EMUI) They often have connection problems, and the reason is because of the firmware. Huawei/Honor, which aggressively optimizes background processes and restricts access to Bluetooth for third-party applications.

In this article, we will discuss three official ways of connecting (via Mi Fit, Zepp Life, and Google Fit), as well as the unique Honor settings that need to be changed for stable operation, separately focusing on common errors such as “Device not found” or “Synchronization interrupted” – their solution often requires manual setting of permissions for the application.

If you've tried to connect the scales and you get an error message, skip the first partition and go straight to the troubleshooting section. For beginners, we'll start with the basic setup.

Phone and weight requirements before connection

Before starting synchronization, make sure your equipment meets the minimum requirements:

• 📱 Smartphone Honor: models on EMUI 10.0+ magic UI 4.0+ (For example, Honor 50, Honor X30, Honor Magic 4.Old devices on the EMUI 9.0 may not be supported BLE 5.0.
• 🔋 Xiaomi scales: check battery power (the display should display a charge indicator or flash Lo when discharged). Mi Smart Scale 2 models run from 4×AAA Xiaomi Smart Scale 3 – from a lithium battery.
• 📶 Bluetooth: The phone must be enabled Bluetooth 4.2+ (Check in the settings → Wireless networks. Xiaomi scales do not support Wi-Fi connectivity.
• 📥 App: The latest version of Mi Fit (for weights until 2022) or Zepp Life (for new models) is installed.

Important: if you use Honor with HMS services (without Google), create a Huawei ID account in advance - it will be required to log in to Zepp Life. Mi Fit will require a Xiaomi account (you can register via +7 or email).

Method 1: Connect via the Mi Fit app (for weights up to 2022)

The Mi Fit app is the official tool for syncing old scale models (Mi Smart Scale 2, Mi Body Composition Scale).The interface is intuitive, but Honor requires additional permissions.

Connection steps:

1. Install Mi Fit from AppGallery or Google Play (links: AppGallery, Google Play).
2. Launch the app and log in via Xiaomi Account (if you don’t have an account, sign up by phone number).
3. Click Profile → Add the device → Libra.
4. Stand on the scale -- you're going to have 0.0 on the display, or a flashing indicator -- -- that's a search signal.
5. In the app, select your scale model from the list. If there is no model, select Mi Smart Scale 2 (Universal Protocol).
6. Confirm the connection in the pop-up window “Allow Mi Fit to use Bluetooth?”

Once the scales are successfully synchronized, they will automatically transmit the weight data to the app. If the process is stalled during the search phase, check:

• 🔄 Reboot Bluetooth on your phone (Settings) → Bluetooth → Off/On).
• 📵 Make sure the scales are no further than 1 meter from the phone (walls and metal objects block the signal).
• 🔋 Replace batteries in scales (even if the indicator shows charge, contact may have oxidized).

Method 2: Sync with Zepp Life (for new models)

Since 2022, Xiaomi has moved new devices (including Smart Scale 3) to the Zepp Life platform, the same app used for the Amazfit watch. On Honor, it is more stable than the Mi Fit, but requires additional permissions.

Instructions:

1. Download Zepp Life (AppGallery or Google Play)
2. Register with Huawei ID, Google or Xiaomi Account.
3. Go to Profile → Add the device → Libra.
4. Choose the Xiaomi Smart Scale 3 or Mi Body Composition Scale 2.
5. Stand on the scale, and you'll see a connection request on your phone screen. Click Confirm.

If the scales are not found, try an alternative method:

1. Open your phone settings → Apps → Zepp Life → Permissions.
2. Turn on all switches: Location, Bluetooth, Warehouse, AutoRun.
3. Go back to the app and repeat the search.

💡

If the scales are connected but no data is saved, check the sync settings in Zepp Life → Profile → Account settings → Data Sync. Enable Auto Sync and select Google Fit or Apple Health (if you use it).

Method 3: Connecting through Google Fit (Universal Method)

If native applications (Mi Fit or Zepp Life) fail to work, you can use Google Fit as an intermediary, which is suitable for all weight models, but requires prior synchronization with Mi Fit or Zepp Life.

Algorithm:

1. Install Google Fit from Google Play (on Honor without Google services use it) APK-version).
2. Open Mi Fit or Zepp Life and go to Profile → Settings → Data Sync.
3. Connect your Google Fit account (enter your login and password from Google).
4. Stand on the scale – the data will be automatically transferred to Google Fit in 1-2 minutes.

The advantage of this method is cross-platform: data will be available on any device with Google Fit (including iPhone or tablet).

• 🕒 Synchronization can be delayed up to 5 minutes.
• 📊 Not all metrics (such as muscle mass or water level) are passed to Google Fit.
• 🔄 When changing the phone, you will need a second authorization.

Solving Connection Problems on Honor

If the scales are not connected or permanently disabled, the problem lies in the Honor settings. Below is a checklist of solutions for typical errors:

For Honor models on Magic UI 7.0+ (such as Honor Magic 5), check out:

1. Settings → Wireless → Bluetooth → Additional → Compatibility Mode (enable).
2. Settings → Applications → Special Access → Battery Optimization → Find Mi Fit/Zepp Life and turn off optimization.

💡

On Honor with EMUI 10.0-12.0, the most common way to disable the Adaptive Battery feature in the application settings is to aggressively close the background processes, including synchronization with weights.

How to improve the accuracy of measurements

Even after successfully connecting Xiaomi scales can show inaccurate data. Here are 5 rules to improve accuracy:

• ⏰ Measurement time: Weigh yourself on an empty stomach in the morning (after the toilet, but before breakfast), the difference between morning and evening weight can be as much as 1-2 kg.
• 👕 Clothing: Take off your shoes and outerwear. Use the Naked Weight mode in the app settings to accurately calculate your fat mass.
• 📍 Position of the scales: place them on a hard surface (tile, laminate). Carpet or soft floor distorts the reading by 0.3-0.7 kg.
• 🔄 Calibration: once a month, check the scales with weights (for example, a 5-pound bottle of water). deviations greater than 0.2 kg require calibration.
• 📱 Software Update: In Mi Fit or Zepp Life, check regularly for firmware updates for scales (Device Settings) → Update).

For models with body composition analysis (Mi Body Composition Scale 2):

• 💧 Drink water 30 minutes before measurement (dehydration distorts fat and muscle performance).
• 🏋️ Do not weigh yourself immediately after exercise (wait 2-3 hours).
• 👴 Indicate in the profile the real age and height – the algorithm calculates the norms based on this data.

💡

If the scales show an error of "Err", it means overload (usually >150 kg) or unstable surface. Try to stand on the scale slowly, spreading the weight evenly.
