Xiaomi Body Composition Scale S400 is a body-composition scale. It measures body weight and body-composition estimates and synchronizes supported readings to its companion app.

The product is compatible with Xiaomi Home / Mi Home for the exact version described here. Official Xiaomi documentation states that S400 pairs only with Mi Home/Xiaomi Home and not Mi Fitness.

Dimensions is 300 × 300 × 24.55 mm; Weight is 1.45 kg; Measurement range is 0.1–150 kg; Wireless connectivity is Bluetooth Low Energy 5.0; Power supply is 3 × AAA batteries; Operating temperature is 0–40 °C.

The scale should be used on a hard, level floor and with bare feet when body-composition measurements are required. Profiles and historical results are handled in Xiaomi Home, so household users should set up the correct account and user profile before comparing trends over time.

Activity, body-composition and wellness measurements are consumer estimates and are not a substitute for medical diagnosis. App support is model-specific and should not be inferred from Xiaomi branding alone.
