Get your Google Developer Project Number (a 12 digit number) from a the Google Developers Console

Update project_number in config.ini to be your Google Developer Project Number.

Modify any other variables you'd like in config.ini with your own choices and start the sync using python3 app.py

Sync examples:

• With date stamps : python3 app.py -s 2016-08-20 -e 2016-08-22
• Last 3 days : python3 app.py -s "2 days ago" -e tomorrow
• January month : python3 app.py -s "jan 1 2016" -e "feb 1 2016"

Setup autosync:

You can setup a cron task to automatically sync everyday at 2:30 AM.

30 2 * * * /path-to-repo/fitbit-googlefit/cron.sh >> /path-to-repo/fitbit-googlefit/cron.log 2>&1

Add above line to your cron tab: crontab -e in Linux. Sync logs will be stored to cron.log in repository.

Headless authentication

---

If you want to do the authentication process on a system without a display - such as a raspberry pi or a remote server, pass --console or -c option to the authentication scripts. See below examples.

python3 auth_fitbit.py -i clientid -s clientsecret --console

python3 auth_google.py -i clientid -s clientsecret --console

Note :

1. Get command line help using the -h flag.
2. Arguments passed through command-line take higher priority over config.ini values.
