Describe the bug

Wrong results for Visceral Fat and Body Fat I have a Mi Body Composition Scale 2 (XMTZC05HM) and get wrong results when calculating, especially for Visceral Fat and Body Fat. If I query these values from other scales, then they are correct.

What can be the reason? Is it the scales or the application cannot be used for the Mi Body Composition Scale 2 (XMTZC05HM)?

To Reproduce Running python 3.8 on a raspberry pi

Expected behaviour Maybe based on the Mi Body Composition Scale 2 ??

Screenshots NOP

Some other values also deviate, but this is not so critical.

What can I do so that the values are evaluated in a similar way to other scales?
