You have to register your own Fitbit and Google Fit applications. This setup is a one time thing.

1. Install dependencies

This is a python3 application so install all the dependencies

• Create virtualenv virtualenv fitbitenv
• Activate env source fitbitenv/bin/activate
• Install dependencies using pip3 install -r requirements.txt

2. Fitbit setup

All instructions below must be performed using the same Fitbit account you want to sync with Google Fit.

• Register a new Fitbit application on Fitbit Developers Console
• Use the information below:

Application Name : --
Description : --
Application Website : --
Organization : --
Organization Website : --
OAuth 2.0 Application Type : **Personal**
Callback URL : http://localhost:8080/
Default Access Type : Read-Only

Note : 
1. Use your own information for fields marked --
2. Make sure you copy the Callback URL exactly (including the last /)
3. Application Type MUST be Personal

• Hit save and make a note of OAuth 2.0 Client ID and Client Secret
• Navigate to auth folder cd /auth
• run python3 auth_fitbit.py -i <client-id> -s <client-secret>
• This opens a popup in the browser. Authenticate and done!

3. Google Fit setup

• Go to the Google Developers Console
• Click Continue. Then select Go to credentials and select Client ID
• Under Application type, select Other and hit Create
• Make a note of client ID and client secret
• Navigate to auth folder cd /auth
• run python3 auth_google.py -i <client-id> -s <client-secret>
• This opens a popup in the browser. Authenticate and done!

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

• 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"

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.

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

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