How to turn on Xiaomi scales: full instruction for all models

Xiaomi’s smart scales are not just a weight measurement device, but a full-fledged health tracking assistant. They analyze body composition, sync with a smartphone, and integrate into the Mi Home ecosystem. However, many users face the problem that the scales they buy are not turned on or responsive to presses, most often due to improper device preparation or basic errors on the first run.

In this article, we’ll look at how to turn on Xiaomi’s scales from the budget Mi Smart Scale 2 to the advanced Mi Body Composition Scale 2 with muscle analysis. You’ll learn what to do if the indicator doesn’t light up, how to reset the settings to factory settings, and why the scales may not sync with the smartphone. And we’ll also reveal the hidden function of forced activation through resetting the battery contacts, which are not written in the official instructions.

What Xiaomi Weight Models Are and How to Distinguish Them

Xiaomi has several smart scales that look similar but have different features and ways to incorporate them, and here are the main models that are found on the market:

• 🔹 Mi Smart Scale 2 is a budget model with weight measurement and IMD (Body mass index: 4 batteries running AAA, no display.
• 🔹 Mi Body Composition Scale 2 is an advanced version with an analysis of 13 body parameters (muscle mass, bone tissue, water in the body). LED-display and supports Bluetooth 5.0 connection.
• 🔹 Xiaomi Smart Scale (1st generation) is an aging model with minimal functionality. Often requires manual reset when first turned on.
• 🔹 Mi Smart Scale Lite – Simplified version without synchronization with the application, local weighing only.

To see what model you have in your hand, look at the bottom of the scales – there is a marking (for example, MJSXJ02YM for Mi Body Composition Scale 2). Also, the models differ in design: the Mi Smart Scale 2 has a glass surface with rounded corners, and the Mi Body Composition Scale 2 has a rectangular metal body with touch buttons.

Preparing the scales for the first inclusion: what to do

Before you turn on the scales, make sure you follow all the preparatory steps. Often users miss this stage, which causes the device to not respond to the presses or sync with the smartphone.

Pay special attention to batteries. Xiaomi scales use:

• 🔋 4 batteries AAA — Mi Smart Scale 2 and Mi Body Composition Scale 2.
• 🔋 3 batteries AAA — For older models Xiaomi Smart Scale.
• 🔋 Built-in battery - only in rare modifications for the Chinese market (requires charging on the basis of the new battery). USB-C).

If the scales are not turned on after installing the batteries, check:

1. The polarity of the batteries (plus to plus, minus to minus).
2. Contacts in the battery compartment – they must be clean, without oxidation.
3. The battery life (even new ones can be discharged).

💡

If the scales have been lying unused for a long time, remove the batteries for 10 seconds, then set back.This will drop the residual charge in the capacitors and may solve the power problem.

How to turn on Xiaomi scales: step-by-step instructions

The process of turning on depends on the scale model. Below is a universal instruction that is suitable for most Xiaomi devices.

Method 1: Standard inclusion (for all models)

1. Set the batteries according to the polarity.
2. Put the scales on a flat, hard surface (tile, laminate, wood) and don't use carpet or soft coating, because it'll interfere with the sensors.
3. Step on the scale with one foot (not all weight!) and wait for the display or app to show.
4. If the scales do not respond, get off them and step back in 5 seconds.

Method 2: Forced inclusion through reset (if scales do not respond)

If the standard method didn’t work, try a hardware reset:

1. Remove the batteries from the bay.
2. Press and hold the power button (if any) for 10-15 seconds.
3. Install the batteries back, keeping polarity in mind.
4. Step on the scales - they should be turned on in calibration mode (the display will appear 0.0 or ---).

For models without an on button (e.g., Mi Smart Scale 2), the reset is performed as follows:

1. Remove the batteries.


2. Close the contacts in the battery compartment with a metal object (for example, a paper clip) for 5 seconds.




3. Set the batteries back and step on the scale.

Why Xiaomi scales are not included: top-5 causes and solutions

If after all the manipulations the scales still do not respond, the reasons may be as follows:

⚠️ Note: If Xiaomi scales after a fall or impact stopped turning on, do not try to disassemble them yourself. Inside the device are accurate strain gauges that are easy to damage.

How to lose Xiaomi scales to factory settings

Resetting to factory settings helps if the scales:

• 🔄 Not synchronized with the smartphone.
• 🔄 Incorrect data (for example, weight 120 kg at real 70 kg).
• 🔄 Hanging on the screen. --- err.

Resetting instructions:

1. Make sure the scales are off (remove the load and wait 10 seconds).
2. Press and hold the power button (if any) for 15 seconds.
3. For models without a button: 1. Remove the batteries. 2. Press the scale platform with your hand (as in weighing) and hold for 10 seconds. 3. Set the batteries back.
4. After resetting the scales should show 0.0 or a flashing indicator.

If the reset didn’t help, try reflashing the scales through the Mi Fit app:

1. Open the application and go to Profile → Devices → Your scales. → Settings (⚙️) → Update firmware.
2. Confirm the update and wait for the process to be completed (the scales should flash blue).

💡

Resetting removes all stored user data, and after the procedure, the scales will have to be re-assigned to the Xiaomi account and calibrated.

Synchronization of Xiaomi scales with a smartphone: step-by-step setting

Xiaomi scales are paired with a smartphone through Mi Fit or Zepp Life apps (for new models). Without synchronization, you can't see the extended body composition data. Here's how to plug the scales in:

1. Download and install the application: 📱 Mi Fit for older models (Mi Smart Scale 2). 📱 Zepp Life – Mi Body Composition Scale 2).

Xiaomi

Bluetooth

Step on the scales - they should turn on and start looking for the device.

Add the device (+) → Libra → Your model

Frequent Mistakes When Turning On Xiaomi Libraries and How to Avoid Them

Even after successful activation, users often encounter errors, and here are the most common ones and solutions:

• 🚫 Error or --- — Solution: Get off the scale, wait 10 seconds and step back again, holding the weight for 5 seconds.
• 🚫 The scales show the wrong weight - check the surface level. If the problem persists, calibrate through the app (Device settings) → Sizing).
• 🚫 Not synced with your phone – make sure your smartphone settings include Bluetooth and geolocation permission (required for Bluetooth) LE).
• 🚫 Libras turn off as soon as they turn on, most likely the batteries are dead. Try replacing them with new ones, even if the old ones seemed to work.

Another common problem is that the scales don't recognize the user, and this happens if you:

• You weigh with bare feet (for accuracy, it is better to use thin socks).
• The weight is not evenly distributed (stand still, not leaning on one leg).
• The app does not specify your parameters (height, age, gender).
