Setup

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

Usage

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.
