ESPHome adds local readings from Xiaomi Smart Scale S200 and Body Composition Scale S400 devices. Both supply weight and the scale’s user-profile number; the S400 also supplies heart rate, two electrical-impedance readings and an indication that a measurement is complete.

The component listens to the scale’s encrypted Bluetooth broadcasts and needs its encryption key to read them. Dckiller supplies the component and companion guide. The readings do not include calculated body-composition estimates.
