The Xiaomi Mi Smart Scale 2 (or the newer Mi Body Composition Scale series) has become an integral part of the Mi Home ecosystem for health care professionals, but many users face the problem that the device does not turn on after unpacking, does not respond to clicks or does not connect to the application, 80% of the time it is due to improper activation or basic configuration errors.
In this article, you will find step-by-step instructions for the first switch on Xiaomi Mi Smart scales, including nuances for different models (from Mi Scale 1 to Mi Smart Scale 3), as well as solutions to typical problems - from lack of weight response to synchronization errors with Mi Fit or Zepp Life. We will discuss what to do if the scales do not show data on the screen, how to reset to factory settings and why the device may suddenly shut down.
We will focus on the hidden features that are not mentioned in the official instructions: how to turn on the body composition measurement mode (if supported by your model), how to calibrate the scales without the application, and what flashing indicators on the display mean.
Preparing for the first turn on: what to do before activation
Before you put the scales on the floor and wait for a reaction, follow a few mandatory steps, and ignoring them is the main reason why the device does not turn on the first time.
1. Check the trim. In the weight box Xiaomi Mi Smart should be:
- 📦 The scales themselves (with a protective film on the display)
- 🔋 4 type batteries AAA (or built-in battery for models with USB-C)
- 📄 Short instructions in several languages (including Russian)
- 🔑 Key to remove the battery compartment cover (if provided)

2. Set the batteries correctly. Open the compartment on the back of the scales (pull the notch or use the key from the kit). Insert the batteries AAA with polarity in mind, the diagram inside the compartment indicates where «+», a where "-." Do not use rechargeable batteries - they may not provide enough voltage for the correct operation of the sensors.

- 📱 Zepp Life (new models starting with Mi Smart Scale 2)
Download links:
- 🤖 Mi Fit for Android
- 🍎 Mi Fit for iOS
- 🤖/🍎 Zepp Life (official website)
⚠️ Note: If you are using Mi Smart Scale 3 or later, the Mi Fit app may not recognize the device. In this case, be sure to install Zepp Life - it supports all current Xiaomi weight models.
Step-by-step: how to turn on the scales Xiaomi Mi Smart
Now, to the basic process, follow the instructions strictly in the steps, and that will eliminate most errors.
Step 1. Activation of the scales
- Put the scales on a flat, hard surface (tile, laminate, wooden flooring) and do not use carpet or soft coating, because it distorts the readings of the sensors.
- Press the center of the scale platform with one finger, and the display should show the words "0.0" or "Lo" (if the batteries are dead).
- If the screen is not responding, check: 🔋 Properly Installed Batteries (Flip them and try again) 📵 The presence of a protective film on the display (it can block the sensor) 🔌 Battery compartment contacts (wipe them with a dry oxidation cloth)
Step 2: Connect to the application
- Open the Mi Fit or Zepp Life app on your smartphone.
- Go to the Profile section → Add the device (or press «+» top-right).
- Select the Libra category and model of your device (e.g. Mi Smart Scale 2).
- Follow the instructions on the screen: the app will ask you to stand on the scale. Do it with your bare feet (the socks distort the readings of body composition sensors).
Step 3: Calibration and first weighing
- 📏 Once you've connected the scales, they'll automatically calibrate, and the display will show you a sign "CAL" — Do not leave the platform for 5-10 seconds.
- 👤 Enter your sex, age, height data in the app, and this is necessary to correctly calculate body mass index (BMI) and percentage of fat.
- 📊 Wait for the data to sync. Your weight will appear on the scale screen, and the app will have full analytics (if the model supports body composition measurement).

Xiaomi scales are not included: reasons and solutions
If after all the manipulations the scales still do not respond, check the following points:
1. Nutrition problems
- 🔋 Discharged batteries: even new cells can be partially discharged. Try replacing them with fresh ones (for example, Duracell or Energizer).
- 🔌 Oxidized contacts: wipe the contacts in the battery compartment with a cotton swab soaked in alcohol.
- 🔄 Resetting: Remove the batteries for 10 minutes, then set back – this will reset the device to factory settings.
2. Display errors
- 📵 The screen is not on: check if the protective film is removed. In the Mi Smart Scale 2 models, it is transparent and almost invisible.
- 🔍 Blinking "Lo": signal low battery charge. Replace them even if they're new - perhaps marriage.
- ❌ Err: Sensor error: Put the scales on a perfectly flat surface and reset (remove the batteries for 30 seconds).
3. Connection problems
- 📱 Not in the app: make sure your smartphone is enabled with Bluetooth and geolocation (necessary for device search).
- 🔄 Continuously switching off: update the Mi app Fit/Zepp Life to the latest version. There are synchronization bugs in the old versions.
- 🌐 Does not work over Wi-Fi (for Mi Smart Scale 3): check if the scales are connected to your network in the app settings.
What if the weight is not the right weight?
⚠️ Warning: If after replacing the batteries, the scales are still not turned on, and the screen is on fire "E1" or "E2", This indicates a hardware malfunction, in which case, don't try to disassemble the device yourself, it will deprive you of warranty.
How to lose weight Xiaomi Mi Smart to factory settings
Reset may be required if the scales start to glittle, do not sync with the application or show incorrect data.
For the Mi Smart Scale 1/2:
- Remove the batteries from the bay.
- Press and hold the reset button (a small hole next to the battery compartment) for 10 seconds. Use a paper clip or toothpick.
- Set the batteries back up. Libras will turn on in factory settings (the screen will show "0.0").
For the Mi Body Composition Scale and Mi Smart Scale 3:
- Open the Zepp Life app.
- Go to Profile. → My devices. → Weight settings → Data resetting.
- Confirm the action. The scales will automatically reset.
💡

What to do after the discharge:
- 🔄 Re-enter the connection procedure (see section above).
- 👤 Update your profile details (height, age, gender) – this is critical for measurement accuracy.
- 📊 Conduct a test weighing to ensure the correctness of the sensors.
Hidden functions of the scales Xiaomi Mi Smart: what does your device
Many users use Xiaomi Mi Smart scales only to measure weight, without even knowing about the additional features.
1. Measurement of body composition
The Mi Smart Scale 2 and later models support analysis of 10–13 parameters, including:
- 💪 Muscle mass (shows how many pounds are in muscles)
- 💧 Water level in the body (normal - 50-60%)
- 🦴 Bone mass (important for the diagnosis of osteoporosis)
- 🔥 Basic metabolism (BMR) (How many calories does the body spend at rest)
- 👴 Metabolic age (comparing your metabolism to the average for your age)
To see this data, stand on the scale with bare feet and wait for synchronization with the Zepp Life app.
Guest mode
If you have multiple people using the scale, you don't have to register everyone in the app.
- In the Zepp Life app, go to Profile → Weight settings → Guest mode.
- Activate the option. Now the scales will show weight without reference to the profile.
- To save your guest data, click on their weight in the measurement history and select Save as a new user.
3. Synchronization with other services
Xiaomi Mi Smart scales can be integrated with popular fitness platforms:
- 🏃 Google Fit: Data is automatically exported to Google.
- 🍎 Apple Health: sync is available for iPhone.
- 📊 MyFitnessPal: weight and body parameters are taken into account in the daily diet.
To connect integration, go to Profile → Settings → Synchronization of data in the Zepp Life application.
💡
To measure body composition accurately, weigh yourself at the same time (preferably on an empty stomach in the morning) and in the same clothes (or without), and the difference in time or meals can distort the results by 5-10%.
Frequent mistakes when using Xiaomi Mi Smart weights
Even after successful inclusion, users often face problems that spoil the experience.-5 Mistakes and explain how to avoid them.
1. Weighing in clothing or shoes
Body composition sensors (BIA-analysis) works through electrical impulses that pass through the body, clothing or shoes with thick soles distort the results, the best option is bare feet and minimal clothing (for example, a tracksuit).
2. Use on soft coatings
Carpet, linoleum or uneven floors lead to unstable readings. Xiaomi Mi Smart scales are calibrated to a hard surface. If your bathroom is only heated tiles, put the scales on a wooden stand (for example, a cutting board).
3. Ignoring firmware updates
The manufacturer regularly releases updates for weights that improve sensor accuracy and add new features.
- Open Zepp Life.
- Go to Profile. → My devices. → Weight settings → Firmware update.
- If a new version is available, click Update and wait for the process to be completed (the scales must be on and be near the smartphone).
4. Improper storage
If the scales lie unused for a long time (for example, in a closet), they can discharge or fail.
- 🔋 Remove the batteries if you have not used the scales for more than a month.
- 🌡️ Store in a dry place at a temperature of 0-40°C (moisture can damage sensors).
- 📦 Do not put heavy objects on the scales - this deforms the platform.
5. Neglect of calibration
Xiaomi Mi Smart scales require periodic calibration (every 3-6 months) to perform:
- Put the scales on a flat surface.
- Stand on them and hold the weight for 10-15 seconds (on the screen will appear "CAL").
- Compare the readings with reference weights (e.g. weights). If the difference is greater than 0.3 kg, repeat the calibration.
