Support for s400

[gspretorius]

Tried using app with new s400 scale Any chance of extending app to support the new version?

S400 is not supported at the moment and unfortunately if it will be or when. I cannot find much info about that scale from developer perspective.

Hello,
I find the XIAOMI IOT specification seems available at the site below
Maybe that's useful

Here are the errors that I got during a scan with s400 scales. In the settings I chose "Mi Body Composition Scale 1/2".
Hope that helps.

I'm currently working on some temporary solution for S400 based on OCR
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 am getting the same errors when setting to "Mi Body Compositon Scale 1/2", when setting to "Mi Scale" I recieve an result which is more then 2,5x of the actual weight and no further stats.
Maybe this helps in debugging.

Do you uave any news about S400 support?

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.

Add support Mi Body Composition Scale S400 #1388
