CTHRU / Hitrava

Introduction

Hitrava converts health activities registered using a Honor or Huawei activity tracker or smart watch in the Huawei Health app into a file format that can be directly uploaded to Strava.

Hitrava Web

An alpha release of Hitrava Web is now available. If you prefer on-line conversion in a web app with GUI over a script, learn more on https://cthru.hopto.org. (Note: my website is not up all the time, plan your visit between 08:15 and 22:45 CET)

  • Python 3.5.1 is the lowest minimum required version (compatibility tested on this version).
• A Huawei account to request your health data.
• 7-Zip stand-alone version to convert directly from an encrypted Huawei Health ZIP file. Currently, this method is only supported on Windows operating systems.

Installation Procedure

Step 1 - Install Python

Only required if you don't have a (suitable) python installation on your system.

• Download the latest Python version for your operating system from the Python website.
• Run the Python installer (Windows) or follow the instructions for your operating system.

Step 2 - Download and Extract Hitrava

• Go to the Releases page to download the source code of the latest Hitrava release.
• On the Releases page, in the Assets section, click on the Source code (zip) link to download the sources.
• Save the ZIP file with the sources on your system.
• Extract all contents of the ZIP file with the sources to a location of your choice on your system.

Step 3 - Download and Extract Stand-alone 7-Zip

NOTE: This step is required to convert encrypted Huawei Health ZIP files.

• Download the latest 7-zip stand-alone console version from the 7-Zip website. The stand-alone version can be identified by the description below:

7-Zip Extra: standalone console version, 7z DLL, Plugin for Far Manager

• Extract the file 7za.exe from the downloaded archive and place it in your Hitrava installation folder from step 2 above. Your Hitrava installation folder should now contain at least the following files.

Hitrava.py
7za.exe
Run_Hitrava_Decrypt.cmd

How to convert your health activities and import them in Strava

All users can use conversion from a ZIP file or a JSON file.
For users with rooted phones, legacy file and tar options are still available.

Windows Users - Encrypted ZIP conversion procedure

NOTE: As of late October 2020, the latest version of the Huawei Health app obliges you to provide a password with which your data in the ZIP file will be encrypted. If you need to convert from an older non-encrypted ZIP file, please refer to the corresponding example.

Activities can be mass converted using the data in a ZIP file that you can request in the Huawei Health app.

The procedure below assumes that you installed Hitrava and are logged in with your Huawei account in the Huawei Health app. If you don't have a Huawei account, you can create one in the app.

Step 1 - Request your data in the Huawei Health app

• On your phone, open the Huawei Health app.
• Tap the 'Me' button in the lower right-hand corner of the main screen.
• Now tap on your account name on top of the screen.
• Tap on 'Privacy Center'.
• Tap 'Request Your Data'.
• Select 'Health' from the list and confirm your selection.
• You will be obligated to enter a password to encrypt the requested data with. You will need this password later in step 3 below.
• Follow any further in-app instructions.
• Wait for the mail from Huawei to arrive with a link to download the data (ZIP file).

Step 2 - Download your requested data

• In the mail from Huawei, click on the link to download your data and follow the instructions.
• Put (a copy of) the downloaded ZIP file in the Hitrava installation folder and rename it to HiZip.zip.

Step 3 - Convert the data with Hitrava

Tip: If you're on Windows and you're not familiar with the Command Prompt or just want to do a quick conversion with default arguments, you can use the Run_Hitrava_Decrypt.cmd batch file.

• Open the Run_Hitrava_Decrypt.cmd file with a text editor and change the password 123456 to the password you provided in step 2 above.
• double-click the Run_Hitrava_Decrypt.cmd file in the installation folder of Hitrava.
  This will convert all available activities in the ZIP file from the previous step.

• Open a Command Prompt and change the directory to the installation folder of Hitrava.
• In the Command Prompt, run Hitrava.py with the --zip command line argument. You can start from the default example command below or add / change command line arguments as you need.

IMPORTANT: You must replace the password 123456 with the password you provided in step 2 above.

Hitrava.py --zip HiZip.zip --password 123456 --json_export

The above command will generate both the original HiTrack files and the converted TCX files for ALL activities to the output subfolder of the Hitrava installation folder. In this folder:

• Files without an extension are the Huawei HiTrack files which contain the raw unconverted data of an activity.
• Files with the .json extension represent an exported copy of the JSON data of a single activity.
• Files with the .tcx extension are the converted files suitable for upload to Strava.

Step 4 - Upload your data to Strava

You can now go to the Strava website to import your data.

• Go to the 'Upload and Sync Your Activities' page on Strava.
• Log in with your Strava account.
• Once logged in, use the 'Browse...' button on the page and select the converted TCX files (with the .tcx extension, up to 25 at once) to upload.

Other Operating Systems Users (macOS, Linux, UNIX)

Step 1 - Request your data

Follow the same procedure as for Windows users explained above.

Step 2 - Download and extract your data

• In the mail from Huawei, click on the link to download your data and follow the instructions.
• Extract the following file from the downloaded ZIP file using an unzip tool for your operating system that supports AES encrypted ZIP files.

  Motion path detail data & description/motion path detail data.json

• Put (a copy of) the extracted file in the Hitrava installation folder and rename it to HiJson.json.

Step 3 - Convert the JSON file with Hitrava

• Open a Terminal window and change the directory to the installation folder of Hitrava.
• In the terminal Prompt, run Hitrava.py with the --json command line argument. You can start from the default example command below or add / change command line arguments as you need.

  python3 Hitrava.py --json HiJson.json --json_export
  

  The above command will generate both the original HiTrack files and the converted TCX files for ALL activities to the output subfolder of the Hitrava installation folder. In this folder:
  • Files without an extension are the Huawei HiTrack files which contain the raw unconverted data of an activity.
  • Files with the .json extension represent an exported copy of the JSON data of a single activity.
  • Files with the .tcx extension are the converted files suitable for upload to Strava.

Step 4 - Upload your data

Follow the same procedure as for Windows users explained above.

                        on FROM_DATE or later. Format YYYY-MM-DD

SWIM options:
  --pool_length POOL_LENGTH
                        The pool length in meters to use for swimming
                        activities. If the option is not set, the estimated
                        pool length derived from the available speed data in
                        the HiTrack file will be used. Note that the available

                        converted TCX files will have the same filename as the
                        original input file (except from the file extension).
  --output_file_prefix OUTPUT_FILE_PREFIX
                        Adds the strftime representation of this argument as a
                        prefix to the generated TCX XML file(s). E.g. use
                        %Y-%m-%d- to add human readable year-month-day
                        information in the name of the generated TCX file.

Usage Examples

Encrypted ZIP file conversion example

Use the command below to convert all activities available in the encrypted ZIP file with the Huawei Privacy data (here with filename HiZip.zip) that were started on October, 3rd, 2019 or later.
The ZIP file was encrypted with password 123456 provided in the Huawei Health app.
The following files will be generated in folder ./my_output_dir:

• JSON files with the raw JSON data of a single activity (.json file extension).
• HiTrack files with the unconverted source data of a single activity (no extension, filenames start with HiTrack_).
• Converted TCX files for upload to Strava (.tcx file extension).

 python Hitrava.py --zip HiZip.zip --password 123456 --json_export --from_date 2019-10-03 --output_dir my_output_dir

ZIP file conversion example

Use the command below to convert all activities available in the ZIP file with the Huawei Privacy data (here with filename HiZip.zip) that were started on October, 3rd, 2019 or later. The following files will be generated in folder ./my_output_dir:

• JSON files with the raw JSON data of a single activity (.json file extension).
• HiTrack files with the unconverted source data of a single activity (no extension, filenames start with HiTrack_).
• Converted TCX files for upload to Strava (.tcx file extension).

 python Hitrava.py --zip HiZip.zip --json_export --from_date 2019-10-03 --output_dir my_output_dir

JSON file conversion example

Use the command below to convert all activities available in the motion path JSON file from the requested Huawei Privacy data that were started on October, 3rd, 2019 or later. Source HiTrack files and converted TCX files will be generated in folder ./my_output_dir/json

 python Hitrava.py --json "motion path detail data.json" --from_date 2019-10-03 --output_dir my_output_dir/json

Same as above, but also create an additional export file for each converted activity containing the raw JSON data of that activity from the motion path JSON file.

python Hitrava.py --json "motion path detail data.json" --json_export --from_date 2019-10-03 --output_dir my_output_dir/json

Single file conversion examples

The example below converts extracted file HiTrack_12345678901212345678912 to HiTrack_12345678901212345678912.tcx in the ./output directory

python Hitrava.py --file HiTrack_12345678901212345678912

The next example converts extracted file HiTrack_12345678901212345678912 to HiTrack_12345678901212345678912.tcx in the ./my_output_dir directory. The program logging level is set to display debug messages. The converted file is validated against the TCX XSD schema (requires installed xmlschema library and an internet connection).

python Hitrava.py --file HiTrack_12345678901212345678912 --output_dir my_output_dir --validate_xml --log_level DEBUG

The following example converts an extracted file HiTrack_12345678901212345678912 to HiTrack_12345678901212345678912.tcx in the ./output directory and forces the sport to walking.

python Hitrava.py --file HiTrack_12345678901212345678912 --sport Walk

The next example converts an indoor swimming activity in an extracted file HiTrack_12345678901212345678912 to HiTrack_12345678901212345678912.tcx. The length of the pool in meters is specified to have a more accurate swimming data calculation.

python Hitrava.py --file HiTrack_12345678901212345678912 --pool_length 25

Tar file conversion examples

The first example extracts and converts any HiTrack file found in tar file com.huawei.health.tar into the ./output directory. The output directory will contain both the extracted HiTrack file and the converted TCX XML file.

python Hitrava.py --tar com.huawei.health.tar

In the example below, only activities in the com.huawei.health.tar tarball that were started on August 20th, 2019 or later will be extracted and converted to the ./output directory.

python Hitrava.py --tar com.huawei.health.tar --from_date 2019-08-20
