Why you need Xiaomi Mi Smart Scale 2 and how it works
The Xiaomi Mi Smart Scale 2 is not just a weight measurement device, but a full-fledged body composition analyzer. It defines 13 key parameters, from body mass index (BMI) to muscle and bone mass levels. All data is automatically synchronized with the smartphone through the Mi Fit app (or Zepp Life in new versions), which allows you to track the dynamics of changes in real time.
The main advantage of the model is high accuracy (accuracy up to ± 50 g) and support for Bluetooth 5.0, which provides stable connection even through walls. Libra runs from 4 AAA batteries, which lasts for 8-12 months with daily use. But to start using all the functions, you first need to connect the device correctly to the phone.
In this article, we will discuss:

What you need to connect the scales of Mi Scale 2
Before you start setting up, make sure you have everything you need:
- 📱 Smartphone on Android 5.0+ or iOS 10.0+ Bluetooth 4.0 (or newer)
- 🔋 Xiaomi Mi Smart Scale 2 with Batteries (not included!)
- 🌐 Sustainable Internet connection (for downloading the application and registering an account)
- 📲 Mi Fit (or Zepp Life) app for new devices)

If the scales show an Err error, check their location: they should stand on a hard and flat surface (not on a carpet or tile with irregularities).
Common mistakes and their solutions
Even with the right connection, users face problems, and here are the most common ones and ways to fix them:
| Mistake. | Reason. | Decision |
|---|---|---|
| Err on display | Uneven surface or overload | Put the scales on the tile / table, the maximum load is 150 kg |
| Libras not included | Landed batteries or oxidized contacts | Replace batteries, wipe contacts with alcohol |
| Data is not synchronized | Bluetooth Failure or Outdated Firmware | Update Mi Fit and restart your phone |
| The testimony will jump. | Effects of electromagnetic interference | Keep the scales away from the router, microwave, speakers |
Critical error: if the scales show LO, this means the battery discharge is below the critical level, in which case the data may not be stored even after the replacement of the batteries - a reset is required (press the reset button on the back for 10 seconds).
⚠️ Note: If you are using an iPhone with iOS 17+, Before connecting, disable the “Warn about new Bluetooth devices” function in the privacy settings. Otherwise, the system may block the connection with the scales.
How to sync data with Google Fit and Apple Health
By default, all measurements are saved only in Mi Fit, but they can be automatically exported to other services:
For Android (Google Fit):
- Open Mi Fit → Profile → Settings → Data Synchronization.
- Select Google Fit and log in through your Google account.
- Allow access to data on weight, height and body composition.
For iPhone (Apple Health):
- Go to iPhone Settings → Privacy → Health → Apps → Mi Fit.
- Turn on switches opposite Weight, Growth and Percentage of Fat in the body.
- Return to Mi Fit and confirm sync in Settings → Apple Health.
Once set up, the data will be updated automatically with each weighing. Note: Apple Health can round values to one decimal place, while the Mi Fit retains an accuracy of up to 50 grams.

Hidden features of the Mi Scale 2 scales that you didn't know about
In addition to standard measurements, scales support several useful options:
- 👶 Pregnancy mode: disables body composition analysis (because it is inaccurate during this period), leaving only weight. → Profile → Weight settings.
- 👟 Automatic user recognition: if multiple people use the scale, the app determines who stood up, according to previous data (accuracies up to 90%).
- 📊 Export of data to CSV: You can upload your measurement history to Excel or Google Sheets for analysis.
- 🔒 Protection against accidental pressing: if the scales show 0.0 for more than 10 seconds, they automatically turn off, saving battery charge.
Another little-known possibility is calibrating the scales, and if the reading seems inaccurate, do the following:
- Stand on the scale and wait for a stable value.
- Press and hold the reset button on the back for 3 seconds.
- The scales will blink and reboot - after that, the accuracy must be restored.
⚠️ Note: If you use scales on linoleum or carpet, the readings may be inflated by 0.3-0.7 kg due to surface cushioning. For accuracy, put thin rubber pads under the legs of the scales (come complete with some models).
