@letoth That's awesome. Thanks for testing miauth
with your device!
The UART log you got from the HOTO device looks quite rudimentary: First two bytes simply count up the packet number (iterator), the rest is the encoded message using the iterator as salt - maybe a checksum in the end.
Without having any knowledge about the device, my guess is that it could be possible to decrypt the traffic when you change the decrypt_uart
function to something like this (removing header and shifting the arrays):
def decrypt_uart(key, iv, msg):
it = msg[:3]
ct = msg[3:-2]
...
If this doesn't work, further investigation would be required. Without the device that is not possible for me.
@letoth were you able to decode the notification at this point?
@arjan-kuiper > no :( but if you could, I would appreciate some hint :)
First of all fantastic job you made with miauth! it works with Xiaomi HOTO smart kitchen scale too :) However after successful state 5, the scale sends notifications which I am not able to decode anyhow..... tried your UART decode logic, but it does not work :(
Could you please have a quick look, and you might be able to guess how to decode the values ? see the attached log
