Xiaomi Body Composition Scale S400

[TomaszBojanowski]

Is Xiaomi Body Composition Scale S400 supported by the app?

[lswiderski]

@TomaszBojanowski Not yet. Only Mi Body Composition Scale 2 is supported at the moment. I'm currently working on some temporary solution for S400 based on OCR what should be ready to tests in December. First at android app (https://github.com/lswiderski/mi-scale-exporter) and after that web app.

Great. Thank you.

@TomaszBojanowski
I would be grateful if you (and anyone else who sees this post) would agree to send me your report of the S400 measurement results to my email address: lukasz@swiderski.xyz with information on which phone it was taken.

Thank you

I just bought this scale and the parcel will arrive on Thursday. On Thursday / Friday I will send you my reports.

I’m also interested, will send you a couple of my reports once I manage to make this weight run :)

Hi. Any update on this? Thanks.

Hi @TomaszBojanowski
As I mentioned at lswiderski/mi-scale-exporter#39

I ran some tests and unfortunately without success. The free OCR available on android returns a lot of bad reads which would result in a requirement to correct the data, which is not what automation is all about.

MIOT - specification of device do not have any READ option what's mean It's "impossible" to get data from scale via official API. The only way is "fake" connection with Mi Home app but no one did it yet.

Alternative is to use xiaomi gateway with custom software and connect it to Home Assistant. The gateway does all the work with the connection and gets you the desired value. but not everyone got that gateway.

Hi, i just bought a S400, the Scale 2 in not in stock anywhere in my country or closer EU countries. Any progress for the S400 to be implemented?

[lswiderski]

@Nwanko Just released Android version with support for S400. I'm trying to use the online version, but I have not yet been able to obtain the correct data from the scale via the web interface.

Nice! Will try it when i get home.
