How to properly turn on and configure Xiaomi smart scales: from unpacking to the first weighing

Xiaomi’s smart scales have long been the standard for health and fitness watchers, but even such a simple device can raise questions for beginners: how to turn it on, why it doesn’t sync with your phone, and what to do if there’s a bug on the display. E1 This article will help you understand all the nuances - from unpacking to the first successful weighing.

We're going to look at not only the basic steps, but also the hidden features that the manufacturer doesn't always advertise, like how to lose weights to factory settings without an app, or why readings can differ from a mechanical weight by 0.5-1 kg. And you'll also learn which Xiaomi models support measuring muscle mass and body water levels, which is important for athletes and dieters.

If you have just purchased the Mi Body Composition Scale 2, Xiaomi Smart Scale 2 or the newer Xiaomi Mi Scale 3, take your feet off them. First you need to properly prepare the device – it will take no more than 5 minutes, but save hours on finding solutions to typical problems.

There is no water in this manual, only proven steps that work on all current firmware (as of 2026), and we also added a compatibility table with popular smartphones and figured out what to do if your phone does not see the scales via Bluetooth.

1. Preparing Xiaomi smart scales for the first inclusion

Before you turn on the scales, make sure you follow all the preliminary steps. Many users skip this stage and then encounter errors like E2 (unstable connection) or E3 (weak-signal).

What should be included:

• 📦 Smart scales themselves (model is indicated on the box and on the back of the device).
• 🔋 4 type batteries AAA (They are usually available in the package, but in some regions they are sold without them).
• 📄 Short instructions in several languages (Russian is not always available).
• 📱 QR-Download code for Mi Fit or Zepp Life (depending on the model).

If you don't have batteries in the box, use only alkaline batteries from well-known brands (like Duracell or Energizer), and cheap salt batteries can cause sensor failures, especially in cold rooms.

Important: Xiaomi Mi Scale 3 and newer scales support recharging USB-C, But the first turn on still requires batteries, and that's because of the calibration of the sensors when they first start up.

Installation of batteries and first activation

Now, to the process of activation, follow the instructions Step-by-step to avoid the typical errors:

1. Turn the scales over and find the battery compartment on the back, which is usually covered with a plastic cover that needs to be moved aside (in some models, snapped).
2. Install batteries while observing polarity (+ and − If you mix it up, the scales won't turn on, but it won't hurt the device.
3. Then, close the lid and place the scales on a flat, solid surface (not on the carpet!).
4. Wait for the automatic switch on. The Mi logo or 0.0 should appear on the display, which means that the scales are ready to be adjusted.

If nothing happens after the battery is installed:

• 🔄 Check if the batteries are inserted correctly (try removing and re-inserting).
• 🔋 Try other batteries – perhaps the ones that came with the kit, discharged during storage.
• 📱 Make sure there are no sources of strong electromagnetic interference (microwaves, routers) nearby. 5G).

What do the symbols on the display mean when you turn on:

3. Sync with Mi Fit or Zepp Life app

Without a smartphone connection, Xiaomi's smart scales work like normal scales, only show weight. To get data on fat percentage, muscle mass and other metrics, you need to link them to the app. Here's how to do this:

Step 1. Install the application:

• 📱 For most models, Mi Fit is suitable (available on Android and iOS).
• 🌐 New scales (such as Xiaomi Smart Scale 2) may require Zepp Life (formerly Mi Fit for Amazfit devices).
• 🔄 If you are not sure what application you need, check it out. QR-code-box.

Step 2: Create an account or log in:

1. Open the app and select a region (important for the correct display of units of measurement).
2. Register via email, phone number or account Xiaomi/Google/Apple.
3. Fill out the profile: Specify your exact height, age and gender – this is critical for calculating body mass index (BMI) and other metrics.

Step 3. Add the scales to the appendix:

1. Press. + (Add the device) in the upper right corner.
2. Select the category "Libra" and find your model in the list.
3. Follow the instructions on the screen: You usually have to stand on the scales to send the test data.

💡

If the scales are not on Bluetooth, try turning on Flight Mode on your phone for 10 seconds, then turn it off. This resets the Bluetooth cache and often solves the problem.

If the synchronization fails:

⚠️ Attention: On iPhone with iOS 17+ Bluetooth access for background applications may be blocked. Go to Settings → Mi Fit → Bluetooth and enable the option "Allow background use".

4. First weighing: how to get accurate data

Now that the scales are connected to the application, you can start measuring, but to make the data as accurate as possible, follow these rules:

How to get on the scales correctly:

• 👣 Stand bare feet on metal electrodes (they are usually marked with stripes or dots).
• 🧘 Spread the weight evenly on both legs, do not lean on one side.
• ⏱️ Stand still for 3-5 seconds until a stable value appears on the display.
• 📵 Do not talk or move during measurements – vibrations distort readings.

Optimal conditions for weighing:

If the scales show weight but do not convey body composition data (fat, muscle, water), check:

• 🔋 Battery level (at low charge, additional sensors are turned off).
• 📱 App version (upgrade to the latest in the App Store or Google Play).
• 🧍 Correctness of the entered data in the profile (height, age, gender).

Calibration and resetting of settings

If the scales start to glittle - show the wrong weight, do not turn on or constantly give out an error E1 — It might need calibration or resetting. Here's how to do it:

Soft reset (reset):

1. Turn off the scales (remove the batteries for 10 seconds).
2. Put the batteries back in and wait for the switch to turn on.
3. Stand on the scales - they should be automatically calibrated.

Hard reset (to factory settings):

1. Turn the scales over and find the Reset button (usually hidden in the battery compartment).
2. Press and hold it for 5-10 seconds until 0.0 flashes on the display.
3. After reset, you will have to re-synchronize the scales with the application.

Manual calibration (for experienced users):

1. Stand on the scale and wait for a stable value.


2. Remember the readings (for example, 70.5 kg).




3. Take a weight of known weight (e.g. 20 kg) and place it in the center of the scale.




4 If the readings differ by more than ± 0.3 kg, repeat the soft reset.

⚠️ Warning: Don't try to disassemble the scales to calibrate the sensors! This voids the warranty and improper assembly can cause strain gauge sensors to break.

💡

If the scales are not working properly after reset, check the integrity of the electrodes on the surface. Over time, they may oxidize - wipe them with an alcohol wipe.

6. Common mistakes and their solutions

Even after setting it up properly, users face typical problems, and here are the most common ones and how to fix them:

Problem: Libras aren't included

• 🔋 Check the batteries (even if they're new - maybe marriage).
• 🔌 Make sure the contacts in the battery compartment are not contaminated.
• 📡 Try to turn on the scales in another room (may interfere with the Wi-Fi router).

Problem: The app doesn't see the scales

• 📱 Reinstall the Mi Fit or Zepp Life app.
• 🔄 Turn Bluetooth on/off on your phone.
• 📵 Make sure the scales and phone are on the same network (some models are important).

Problem: Indications jump or are unstable

• 🏠 Move the scales to a harder surface.
• 👣 Stand on the scales slowly, without jerking.
• 🧲 Check if there are any magnets or metal objects nearby.

Problem: body composition (fat, muscle) is not measured

• 🔋 Replace batteries – additional sensors are sensitive to voltage.
• 🧍 Make sure you stand on the electrodes with your bare feet.
• 📱 Update the firmware of the scales through the app (if available).

If none of these methods worked, contact Xiaomi via the official website or chat app. Save the check and the scale serial number (located on the sticker at the bottom) – this will speed up the processing of the request.
