Backup of com.xiaomi.smarthome (Android)

Third party integrations
1

I am having trouble when I am trying to back up the Xiaomi Mi Home app to grab the vacuum access token.

I am using Windows and following the step-by-step procedure as described here: https://home-assistant.io/components/vacuum.xiaomi_miio/

But when I type the ADB-command to make the backup (.\adb backup -noapk com.xiaomi.smarthome -f backup.ab), my Huawei P9 (Android 7) phone says (translated from Norwegian):

“A full backup of all the data is requested”
and
"Since your unit is encrypted, the backup also needs to be encrypted. Supply a password: "

If I don’t supply a password, I am not able to continue.

If i supply a password, an AES256 encrypted backup.ad file is created.

So my questions, I am probably doing something wrong:

  • My unit is encrypted? Might de default so in Android 7?
  • “A full backup”? I really just requested the Xiaomi Mi App?

Please help :slight_smile:

If you are adventurous you can install the current git master (which supports token extraction) of python-miio for testing with the following command:
pip install -e git+https://github.com/rytilahti/python-miio.git#egg=python-mirobo (still using python-mirobo as a name here to avoid potential problems with future installations. The package will be renamed to python-miio soon.) In the best case you would only install this inside a virtualenv.

A tool called miio-extract-tokens will be installed which can be used to extract even encrypted backup files. It will simply extract the backup and print out all the tokens from the database, e.g.

miio-extract-tokens --password 1 backup.ab

Hope this helps, please let me know how it went!

I have tried to install it to virtualenvironments using Python 2.7 and 3.4 but I get the same error when running miio-extract-tokens:

I don’t know what I am doing wrong…

Hey, a good catch! I suppose it is about a missing typing package on python 3.4, python2 is not supported by the library at all.

I just pushed an update into git to install missing requirements, could you please install and try it again?
