Xiaomiβs smart scales are no longer just a weight-measuring device, and today they are full-fledged fitness assistants that can analyze body composition, sync with mobile apps, and even make nutritional recommendations, but many users use only 20 percent of their capabilities, unaware of hidden functions and fine-tuning.
In this article, we will take a look at what Xiaomiβs modern scales can do, from basic models to flagship bioimpedance devices, how to interpret metrics, what data can be exported, and how to integrate scales into the smart home ecosystem, and also reveal a few non-obvious features that are not written in the official instructions.
1. Basic Features: What All Xiaomi Libras Can Do
Even the most budget scales Xiaomi (for example, Mi Smart Scale 2) equipped with functionality that distinguishes them from mechanical counterparts.
- π Precise weighing with an error of up to 50 g (for models with a maximum load of 150 kg) or 100 g (for budget versions). Calibration is automatically performed each time you turn on.
- π± Bluetooth sync with Mi Fit (or Zepp Life for new models) and data is transmitted in real time without manual input.
- π€ Multiplayer mode: Libra recognizes up to 16 users by weight (with accuracy) Β±3 kg) and keep the measurement history for each.
- π Change statistics: The app plots the weight dynamics of a day, week, month or year, with the possibility of exporting to the CSV.
It is important to understand that the basic models (e.g. Xiaomi Mi Body Composition Scale) do not support body composition analysis β they simply transfer weight to the app, but they are lighter (weight of the device itself is ~1.2 kg) and thinner (18 mm), which makes storage easier.
One of the key benefits is automatic user recognition, which analyzes not only weight but also weighing times (e.g. if you always get up on a scale in the morning and another family member in the evening), but if you are close to a weight, two users may have errors, so you will have to manually verify your identity in the app.
2. Body composition analysis: how scales with bioimpedance work
Bioimpedance models (such as the Xiaomi Smart Scale 2 or Mi Body Composition Scale 2) do more than just show weight, they pass a weak electric current through the body (safely!) and calculate based on tissue resistance:
- πͺ Muscle mass (in kg and % of total weight) is important for athletes and those who monitor the terrain.
- 𦴠Bone mass: Low values may signal risk of osteoporosis.
- π§ Water levels: 45-65% for women and 50-65% for men.
- βοΈ Visceral fat (environmental organs) is more dangerous than the subcutaneous fat!
- π₯ Basic metabolism (BMR) β How many calories does the body spend at rest.
But there's a nuance here. The accuracy of the bioimpedance test depends on hydration: if you weigh yourself after exercise or drinking heavily, your fat and muscle scores will be underestimated. The optimal time to measure is on an empty stomach in the morning after going to the toilet.
| Indicator. | Normal for men | Norm for women | What to do with deviations |
|---|---|---|---|
| visceral fat | 1β12 | 1β10 | Reduce sugar intake, add cardio |
| Muscle mass (%) | 38β50% | 30β40% | Increase protein in the diet, strength training |
| Water level | 50β65% | 45β65% | Drink 30-40 ml of water per 1 kg of weight per day |
In the Mi Fit app, you can set targets for each parameter, for example, if your goal is to gain muscle mass, the system will track the dynamics of this value, not total weight, and also scales can calculate body index (BMI), but this indicator is often criticized for being inaccurate (it does not take into account muscle mass).

Before you first use a bioimpedance scale, enter your exact height, age and gender in the app, and without that data, your body composition calculations will be incorrect!
3. Synchronize with Xiaomi ecosystem and third-party services
Xiaomi scales donβt work in isolation β they integrate into the brand ecosystem and support data export to popular fitness apps.
- π Automatic sync with Mi Fit, Zepp Life, Google Fit and Apple Health (for iOS) Data updated every 5 minutes with active Bluetooth.
- π² Smart notifications: The app can remind you to weigh (for example, once a week) or warn you of sudden changes in weight.
- π Smart home integration. Through Mi Home, scales can trigger scenarios -- like turning on a smart lamp when you stand on them in the morning.
- π Export of history in CSV or Excel for manual analysis or transfer to a doctor/trainer.
To sync with third-party services (like MyFitnessPal or Yazio), you will need to connect Mi Fit as a data source, you can do this in the settings of the partner app. Note: some services only support weight import, ignoring body composition.
How to connect scales to Apple Health?
Another useful feature is family access, where you can give your family or coach access to your statistics without revealing your account password, so you can go to Profile in Mi Fit β Privacy Settings β Sharing and add the guestβs email.
4. Hidden functions and life hacks for power users
Even those who have been using Xiaomi scales for years are often unaware of these features:
- π Power saving mode: If the scales are idle for more than 30 seconds, they automatically shut down, but you can force them to sleep by pressing the side button (if you have one in the model).
- π If the scales start to lie, you can calibrate them: put them on a flat surface, press and hold the switch for 5 seconds until the indicator flashes.
- πΆ In some models (for example, Xiaomi Smart Scale 2), you can include a special algorithm for weighing children from 5 years old.
- π‘οΈ Most scales are protected by a protection class. IP54, This allows you to wash them with a damp cloth (but not under a stream of water!).
And scales can weigh objects up to 5 kg with high accuracy (a margin of error Β± 10 g), which is convenient for cooking purposes or sending parcels.
- Turn on the scales (click on them or the power button).
- Wait for the zeros to appear on the display.
- Place the object in the center of the platform.
- Record the weight (in some models, you need to press the display).
βοΈ How to check the accuracy of the scales
If your scale suddenly starts showing a Lo error (low battery charge), take your time buying new batteries.Try to remove the batteries for 10 minutes and insert back - sometimes this resets the sensor error.
5. Comparison of popular models: which scales Xiaomi to choose
Xiaomi has scales for every budget, from simple to professional, and here is a comparison table of current models (2026):
| Model | Bioimpedance | Max, load. | precision | Features | Price (β) |
|---|---|---|---|---|---|
| Mi Smart Scale 2 | β No. | 150 kg | Β±50 g | Thin body, 4 sensors | 1 500 β½ |
| Mi Body Composition Scale 2 | β Yes. | 150 kg | Β±50 g | 13 indicators of body composition, ITO-coating | 2 500 β½ |
| Xiaomi Smart Scale 2 (with bioimpedance) | β Yes. | 180 kg | Β± 100 g | Child support, improved electrodes | 3 000 β½ |
| Xiaomi Mi Scale Pro | β Yes (extended) | 200 kg | Β±50 g | Wi-Fi, synchronization without a phone, metal case | 4 500 β½ |
For most users, the best choice is the Mi Body Composition Scale 2, which offers the best balance of price and functionality. If you want maximum accuracy and price is not important, look for the Mi Scale Pro with Wi-Fi support (data sync even without a smartphone nearby).
π‘
Bioimpedance scales are not recommended for pregnant women, people with pacemakers, and those who have had surgery to install metal implants, and in these cases, it is better to choose a model without analyzing body composition.
When buying, pay attention to the type of batteries. Most Xiaomi scales run from 4 AAA batteries, but some models (such as the Mi Scale Pro) have a built-in battery with USB-C charging. The latter option is more convenient, but the scales get heavier (~1.8 kg vs. 1.2 kg for battery models).
Typical problems and their solutions
Even reliable technology sometimes fails, and here are the most common problems and ways to fix them:
- β Libras are not included. Reason: dead batteries or contact oxidation. Solution: replace batteries, wipe contacts with alcohol. If it doesn't work, reset (hold the 10 second button).
- βοΈ The indications jump or are unstable Cause: uneven surface, dirt on sensors or interference from other Bluetooth devices. Solution: put the scales on a hard, flat surface, wipe your legs, turn off other gadgets next to you.
- π± Out of sync with your phone, because you have an outdated firmware scale or an app that has Bluetooth disabled. Solution: Update Mi Fit in the App Store/Google Play, reboot your phone, reconnect the scales.
If the scales show an Err error, it could mean:
- Overload (weight exceeds maximum).
- Sensor malfunction (you need to contact the service).
- Firmware failure (try to reset to factory settings).
π‘
If the scales after replacing the batteries show an incorrect weight, perform a forced calibration: turn them on, press and hold the button for 5 seconds, then put on a flat surface and wait for 10 seconds.
For models with bioimpedance, the problem of false fat/muscle values is relevant. If you see unrealistic values (for example, 5% fat in the absence of training), check:
- Is the growth in the app correctly introduced?
- Do you weigh yourself immediately after eating/workout?
- Are you standing on a scale with socks or wet feet?
7. How to prolong the life of the scales: care and storage
To make Xiaomi scales last for many years, follow these recommendations:
- π§Ό Clean. Rub the platform with a moist microfiber cloth 1-2 times a week. Use a weak soap solution to remove fat (but not abrasives!).
- π Batteries.3DuracellEnergizer
- π‘οΈ Storage conditions: Avoid direct sunlight and humidity above 80%. Optimal temperature is 10-35Β°C.
- β‘ If the scales start to glittle in the winter, it could be static electricity, the solution is an antistatic spray or a humidifier.
Many users don't know that the scales need to be calibrated periodically, and even if they work correctly, check every 6 months:
- Weigh yourself on a control scale (for example, in a clinic).
- Compare the readings with your Xiaomi scales.
- If the difference is more than 100 g, perform the calibration (see the instructions above).
What if the scales fell?
Xiaomiβs average lifespan is 5-7 years when properly operated, but bioimpedance sensors age over time and can give you a margin of error. If you notice that your body composition has become unstable (with a steady lifestyle), you might want to consider replacing it.
