• 🔹 Xiaomi Mi Scale (first generation) – supports only weight and BMI, but still relevant for the budget segment.
• 🔹 Xiaomi Mi Body Fat Scale – a specialized model for measuring fat percentage.

If your model is not included in this list, check its name on the box or in the documentation. Libras without Bluetooth support (for example, mechanical or simple electronic) can not be connected to the phone.
