Because "Your data belongs to you!"

...and fitbit's own data export sucks.

Manual:

git clone [email protected]:Knio/myfitbit
cd myfitbit
python3 setup.py install

1. Register a new app at https://dev.fitbit.com/apps/new

The app should look like this:

The Callback URL must be exactly http://localhost:8189/auth_code

2. Configure the API keys

Make a file myfitbit.ini in your working directory with the client ID and secret you got from registering the fitbit app:

[fitbit_auth]
client_id = 123ABCD
client_secret = 0123456789abcdef0a1b2c3d4f5

2. Export your data

python3 -m myfitbit

This will open a web browser and prompt you to allow the app to access your data.

It will then begin exporting to your current working directory.

Note that the fitbit API is rate limited to 150 calls/hour, and you can query only 1 day of heartrate data at a time. If you many days of data, you will be rate limited and see an HTTP 429 error. Simply re-run the command an hour later and it will resume downloading where it left off.

3. Generate report

python3 -m myfitbit.report --user 123ABC

Use the user id seen in the output from step 2

This will generate report.html in your current working directory.
