Inconsistent Measurements #655

Closed mzzntn closed 3 years ago

Describe the bug Hi I recently bought a new scale

I moved from a generic Kamtron #373 to a Xiaomi MiScale Body composition 2 I checked the compatibility as mentioned in #650 but the measurements from the two scale are completely different.

As you can see in the picture I gained 20kg of muscle and 5 of fat in 2 days (I know that the measurements aren't completed at the same time but it shouldn't make too much difference)

I suppose that the measurements from the Kamtron are more real but I actually have no really idea at this point :)

I just want to understand which measurement are more accurate and stick with them (even though would be a shame to lose one month of measurements) In the reality I actually have not idea if it's a scale, app or other error.

Additional context Unfortunately I can't measure anymore with the old scale (I changed house)

I just noticed that in #637 #543 #412 similar problems are mentioned

oliexdev commented 3 years ago

so the other values are from the Kamtron scale?

mzzntn commented 3 years ago

Yes, from the 29/10 to 20/11

then it could be possible that the mi scale use some different definitions of the muscle mass and so on. You can't compare different scales from different vendors.
