How to reboot the scales Xiaomi Mi Smart: all the ways and tips

Xiaomi Mi Smart Scale has become an integral part of a healthy lifestyle for millions of users. It accurately measures weight, fat percentage, muscle mass and even syncs with the Mi Fit app. But what if the device suddenly stopped working correctly? Screen getting stuck, sync errors or incorrect readings are typical problems that owners face. In 80% of cases, a simple reboot solves them, but how do you do it correctly so as not to damage the device?

In this article, we will discuss all the official and alternative reboot methods for the Mi Smart Scale 2, Mi Body Composition Scale 2 and other versions. You will learn when soft reset is enough, when full reflashing is required, and how to avoid common errors when working with a gadget. Importantly, the reboot procedure for smart scales is different from conventional mechanical ones - there are nuances with power and synchronization.

Why Xiaomi Mi Smart scales may require a reboot

Before you start resetting, you need to understand the causes of the malfunction. Xiaomi smart scales are not just a mechanism with sensors, but a full-fledged electronic device with firmware, a Bluetooth module and a battery, and any failure in this system can lead to malfunction.

The main signs that the weights need to be reset:

• 🔄 The screen does not turn on when it occurs or shows an error "Err"
• 📱 Scales are not synced with the Mi Fit app for more than 3 days
• 🔋 Battery discharges quickly (less than a month with regular use)
• 📊 Weight readings are 'jumping' or significantly different from real weight readings
• 🔄 Hanging during the connection stage to the phone

Most often, problems arise due to:

• 🔌 Discharged battery (even if the indicator shows charge)
• 📲 Firmware conflict after automatic update
• 📡 Interference in Bluetooth connection from other devices
• 🧲 Exposure to magnetic fields (e.g., if the scale is next to the column)

⚠️ Warning: If the Xiaomi Mi Smart scales show weights with a deviation of more than 3 kg from the real one, don't rush to drop them. First check the surface level - even a slight tilt in 2-3° can distort the sensor readings.

Preparing for a reboot: what to do in advance

Resetting the smart scales is not just pressing a button, but to avoid losing data or damaging the firmware, it's important to prepare properly. Let's start with the most important thing: save the current data. If the scales still work, sync them manually with the Mi Fit app:

1. Open the Mi Fit app on your phone
2. Go to the Profile section → Devices → Your scales
3. Click Sync Data (if the option is active)

If the synchronization fails, try an alternative method:

Make sure the phone and scales are less than 1 meter away

Turn off other Bluetooth devices nearby (earphones, fitness bracelets)

Reboot the phone

Update the Mi Fit app to the latest version-->

Pay special attention to the power supply. Xiaomi Mi Smart scales run from 4 AAA batteries. If they are discharged by less than 20%, this can cause malfunctions in the electronic components. Check the voltage of the batteries with a multimeter - it should be at least 1.35V on each cell. If there is no multimeter, just replace the batteries with new ones (preferably alkaline, for example, Duracell or Energizer).

⚠️ Warning: Never use rechargeable Ni-MH batteries in Xiaomi scales. their voltage (1.2V) is below the threshold for correct operation of the device, which leads to constant firmware failures.

Method 1: Soft reboot (without data loss)

This is the safest method, and it works 70 percent of the time, so that a soft reset doesn't delete user data or settings, it just restarts the system, and it's good for fixing time glitches, synchronization errors, or screen freezes.

Step instructions:

1. Remove all items from the scale platform.
2. Turn the scales over and find the reset button (usually hidden under a rubber plug or next to the battery compartment).
3. Take a thin object (clip, toothpick) and press the button once - a short click should be heard.
4. Wait 10-15 seconds – the Mi logo will appear on the screen, followed by the inscription 0.0.
5. Put the scales on a flat surface and step in for calibration.

If there is no reset button (as in some versions of the Mi Body Composition Scale), use an alternative method:

1. Remove all batteries from the bay.
2. Wait exactly 30 seconds (check the time by stopwatch).
3. Install the batteries back, keeping polarity in mind.
4. Wait for the automatic reboot (it will take up to 1 minute).

After a soft reset, the scales should automatically connect to the phone. If this does not happen, go to Bluetooth Settings on your smartphone and select Mi Scale from the device list.

💡

If after a soft reset the scales show a weight with a deviation, perform a calibration: step on the scales and hold the weight for 10 seconds before the CAL inscription appears.

Method 2: Hard reset (full return to factory settings)

This method is used if a soft reboot has not helped or the scales do not respond at all to the actions. Hard reset completely erases all user data, including the measurement history and binding to the Mi Account. Use it only as a last resort!

Step-by-step:

1. Make sure the scales are off (remove the batteries or wait for the screen to turn off completely).
2. Press the reset button (if any) and hold it for 10-12 seconds until the indicator blinks.
3. Release the button and the inscription rSt (reset) will appear on the screen.
4. Wait for the process to be completed (about 30 seconds). The scales will reset and show 0.0.
5. Now you need to re-connect the device to the Mi Fit account.

For models without a reset button (e.g., Mi Smart Scale 2 without a mechanical button), the procedure is different:

1. Remove the batteries for 1 minute.


2. Set them back, but don't turn on the scales.




3.Step on the platform and hold the weight for 20 seconds.




4 When the screen starts flashing, release - reset is done.

After a hard reset, the scales will be "like new."

• 📱 Reconnect them to the phone via Mi Fit
• 👤 Enter your data (height, age, gender) for correct measurements
• ⚖️ Calibrate (stand on the scale and wait for the signal)

⚠️ Warning: If the scales are not turned on after a hard reset or if E01 shows an error, this indicates a hardware malfunction, in which case repair or replacement of the device is required.

💡

Hard reset is a last resort, and before you do it, try updating the firmware of the scales through the Mi Fit app (Device Settings section).

Method 3: Reboot via the Mi Fit app (for advanced users)

Few people know, but the Mi Fit app has a device diagnostic feature that allows you to reboot the scales software, which only works for models that support OTA- updates (for example, Mi Body Composition Scale 2).

How to do this:

1. Open Mi Fit and go to Profile → Your Devices → Libra.
2. Click on the three dots in the top right corner and select Device Settings.
3. Scroll down and find the Firmware Update item.
4. If a new version is available, click Update – the scales will automatically reboot after installation.
5. If there are no updates, click Reboot the device (this item appears only after a long press on the scale screen).

If your version of the app does not have the “Reboot” option, try an alternative way:

• 📌 Disconnect the scales from your Mi Fit account → Settings → Untie the device.
• 🔄 Reboot the phone.
• 🔗 Re-add the scales through Add the device → Libra.

This method often helps when the scales are connected to the phone but do not transmit data or show an E02 error (Sync Error).

Table: Common Xiaomi weight errors and their solutions

Sometimes scales give out error codes that help diagnose a problem, and the table below shows you how to decipher the most common errors and how to fix them.

If your scales show an error not listed in the table (e.g. E05 or E08), this may indicate a hardware malfunction. In such cases, self-repair is not recommended - you should contact an authorized Xiaomi service center.

What to do if Xiaomi scales do not respond to a reboot

If none of these methods worked, and the scales are still not switched on or synchronized, the problem could be more serious.

1. Libras are not turned on at all (screen is empty)

• 🔋 Check the batteries, even if they're new, the contacts could have oxidized. Clean them with a blower.
• 🔌 Try an alternative power source: Some models support USB charging (e.g., Mi Smart Scale 2 with Type-C connector).
• 🛠️ Take the scales apart (carefully!) and check if the display plume has disconnected.

2.The scales are included but not synchronized

• 📱 Remove the Mi Fit app cache in your phone settings.
• 🔄 Change the phone to connect (sometimes a problem in the smartphone's Bluetooth module).
• 🌐 Check to see if the firewall or VPN connection to Xiaomi servers is blocked.

3.The scales show the wrong weight

• ⚖️ Move the scales to another surface (e.g., from carpet to tile).
• 🧲 Remove magnets, speakers, or other sources of interference nearby.
• 📏 Perform manual calibration: Stand on the scale and hold the weight until it appears CAL.

If the scales are still not working, check if the warranty has expired. Xiaomi official devices have 12 months from the date of purchase. For warranty repairs, you will need a check (electronic or paper) and a box from the device.

💡

Before contacting the service, try to lose weights through the engineering menu (if available). To do this, when turning on, hold the reset button for 15 seconds until the service menu appears (does not work on all models).
