How to turn on Xiaomi smart scales: instructions for all models (2026)

Xiaomi smart scales are not just a weight measurement device, but a full-fledged body composition analyzer with data synchronization via Mi Fit or Zepp Life. However, many users face the problem: the scales do not turn on the first time, do not respond to presses or refuse to sync with a smartphone. In this article, we will discuss all possible ways to turn on the scales Xiaomi Mi Body Composition Scale 2, Mi Smart Scale 2 and other popular models, and also tell you what to do if the device does not show signs of life.

The main mistake of beginners is to try to turn on the scales as a normal mechanical one by pressing them with your foot. Xiaomi smart scales are activated differently: they require a stable power supply (batteries or batteries) and the right sequence of actions. If you have just unpacked the device or have not used it for a long time, first check the battery charge and the status of contacts. Next, we will analyze each step in detail, from preparing for the first turn on to solving typical problems.

This article will be useful for both new weight holders and those who have experienced problems after a firmware update or prolonged downtime. All instructions are relevant for models from 2020 to 2026 and have been tested in practice. If your model is older, please note the section on compatibility with outdated versions of the software.

1. Preparation of Xiaomi scales for the first inclusion

Before you try to turn on the scales, make sure they are ready to go. Even new devices out of the box may require additional manipulation.

Step 1: Install batteries. Most Xiaomi models (e.g. Mi Body Composition Scale 2) run on 4 AAA batteries. They come with a bundle, but are often discharged - check them with a voltmeter or replace them with new ones. In battery models (e.g. Xiaomi Smart Scale 2), make sure that it is at least 20% charged.

Step 2: Contact check: If the batteries are installed but the scales are not responding, check the contacts in the compartment, which may have oxidized or contaminated.

Step 3: Placing it on a flat surface: Xiaomi scales calibrate automatically, but they need a hard, flat surface (tile, laminate, wood) and a carpet or soft linoleum can block the sensors.

  • πŸ”‹ Batteries: Use Duracell (Energizer) batteries to keep the charge longer.
  • 🧹 Cleanliness: wipe the glass surface of the scales with a dry cloth - dirt interferes with sensors.
  • πŸ“± Smartphone: Install Mi Fit or Zepp Life app in advance.

⚠️ Note: If Xiaomi scales were stored in the cold (for example, in an unheated room), let them warm up to room temperature for 15-20 minutes.

2. Standard method of inclusion: step-by-step instruction

If Xiaomi scales are new or have not been used for a long time, include them as follows:

  1. Set the scales on a flat surface, make sure there are no foreign objects underneath.
  2. Press the glass panel with your foot. If you touch it lightly enough, you don't have to stomp. The scales should beeping and show 0.0 on the display.
  3. Wait for the numbers to appear. In 2-3 seconds, the screen will display weight (if you are standing) or zeros (if you just pressed).
  4. Sync with your smartphone. Open Mi Fit, go to Profile β†’ Add device β†’ Libra.

If the scales are not beeping and do not respond to the press, go to the "Problem Solutions" section. If the display lights up but the data is not transmitted to the application, check the Bluetooth resolutions on the smartphone.

Features of models:

  • πŸ“Š Mi Body Composition Scale 2: supports measurement of 13 parameters (muscle mass, body water, etc.).
  • βš–οΈ Mi Smart Scale 2: a more budget version, measures only weight, BMI and fat mass.
  • πŸ”‹ Xiaomi Smart Scale (1st generation): may require double tap to enable.

3. Alternative ways of inclusion

If the standard method doesn’t work, try alternatives:

Method 1: Forced resetting

Sometimes Xiaomi scales hang in hibernation to reset them:

  1. Remove the batteries for 10 seconds.
  2. Set them back up, keeping them polar.
  3. Press the scales with your foot and hold for 5 seconds.

Method 2: Activation through the application

In some cases, the scales are turned on only after connecting to the smartphone:

  1. Open Mi Fit and go to Profile β†’ Add the device.
  2. Select Libra and follow the instructions on the screen.
  3. When the app asks you to stand on the scale, do so – the device should automatically turn on.

Method 3: Calibration of sensors

If the scales are turned on but show incorrect data (e.g., 0.0 or overweight), calibrate:

  1. Stand on the scale and wait for a stable display.
  2. Get off them and get up again in 5 seconds.
  3. Repeat the procedure 3 times – the sensors must be calibrated.

If Xiaomi scales don't turn on after replacing batteries, try using batteries of a different brand. Cheap batteries may not provide enough current to start.

Table 4: Compatibility of Xiaomi scales with applications

Not all Xiaomi scale models work with the latest versions of the applications, and the table below provides up-to-date information on compatibility (2026):

Model of weightsSupported softwareRequired version of BluetoothFeatures
Mi Body Composition Scale 2Mi Fit 5.0+Zepp Life 3.0+Bluetooth 4.2It supports 13 metrics, but requires a firmware update to work with Zepp Life.
Mi Smart Scale 2Mi Fit 4.6+Zepp Life 2.5+Bluetooth 4.0The budget model may not sync with the iPhone on iOS 16+.

Xiaomi Mi Scale (2016–2018)Mi Fit 3.0–4.5Bluetooth 4.0The older model may not work with Android 12+.

If your model is released before 2019, check compatibility with your smartphone before buying. Xiaomi's Bluetooth 4.0 scales often conflict with newer versions of Android/iOS.

5. Problem Solving: Xiaomi scales are not included

If the scales do not respond to pressing, do not emit sounds and do not show data on the display, use this instruction:

Problem 1: Libras do not squeak or turn on

  • ⚑ Check the batteries: replace them with new ones, even if the old ones are β€œlike workingΒ».
  • πŸ”Œ Clean contacts: Oxidation or dirt can block power.
  • πŸ“± Update the firmware: some models require updating through Mi Fit.

Problem 2: Libras are switched on but not synchronized

  • πŸ”„ Reboot Bluetooth: Turn it off and back on on your smartphone.
  • πŸ“² Reinstall the app: Remove Mi Fit and install it again.
  • πŸ”— Reset the connection: in Mi Fit, remove the scales from the list of devices and connect again.

Problem 3: Libra shows an Err or Lo error

Err means sensor malfunction, and Lo means battery discharge.

  • πŸ”‹ For Lo: Replace batteries with alkaline (not rechargeable!).
  • πŸ› οΈ For Err: Try resetting (remove batteries for 1 minute).

⚠️ Note: If after replacing the batteries, the scales of the Xiaomi Mi Body Composition Scale 2 show an Err and do not calibrate, this may indicate damage to the strain gauges.

What to do if Xiaomi scales are filled with water?
If liquid hits the scale, immediately remove the batteries and dry the device for 24-48 hours in a dry place (do not use a hair dryer!). Do not turn the scales on until completely dry. If they do not work after drying, most likely, a short circuit has occurred, and a replacement board is required.

6. Update of Xiaomi's firmware scales

If the scales are turned on but are not running smoothly (e.g., mismeasuring weight or not synchronizing), a firmware update may be required.

  1. Open the Mi Fit app and go to Profile β†’ My devices β†’ Libra.
  2. Click on the three dots in the upper right corner and select Update firmware.
  3. Confirm the update and wait until the completion (the scales should be on and be near the smartphone).

Important: Don't interrupt the upgrade process! If Xiaomi scales go off during firmware, they could fail.

After the update:

  • βœ… Libra will start to synchronize faster.
  • βœ… Improved accuracy of measurements (especially for muscle mass and water level).
  • βœ… Support for new Mi Fit and Zepp Life versions.
