float

A simple utility for exporting body weight from Fitbit to Polar Flow. Useful it, for example, you use Fitbit Aria scales, and want Polar to be updated when you do so.

Usage

Usage: float [options]
Export weight from Fitbit to Polar Flow

Options:
  -h, --help                    Displays this help.
  -c, --credentials <filename>  Read credentials from filename
  -d, --debug                   Enable debug output
  --no-color                    Do not color the output
  --show                        Show the web view on screen
  -v, --version                 Displays version information.

Credentials

Of course, the application needs credentials to access both Fitbit and Polar Flow. These may be provide either by file, or environment variables.

Credentials File

The Fitbit and Polar Flow credentials may be given in an ini file, specified by the -c option:

float -c path/to/credentials.ini

Where the ini file looks something like:

[Fitbit]
username=user@example.com
password=my$trongPa$$word!!

[Polar]
username=user@example.com
password=myOtherPa$$word##

Environment Variables

If no -c (or --credentials) option is given, then application will look for the following environment variables instead: FITBIT_USERNAME, FITBIT_PASSWORD, POLAR_USERNAME, and POLAR_PASSWORD.

Building

To build the application from source code, clone the repository, then:

mkdir -p '/path/to/tmp/build/dir'
qmake -o '/path/to/tmp/build/dir' -r -Wall -Wlogic -Wparser CONFIG+=debug_and_release '/path/to/repo/clone'
make -C '/path/to/tmp/build/dir' all
make -C '/path/to/tmp/build/dir' check

Debugging

For basic debugging, use the -d or --debug flags.

$ ./float -d ...

To see the web view rendered, either natively (on your local Windows/OSX/Linux desktop) or remotely (eg via X11 forwarding over SSH), use the --show option. Otherwise the view will be rendered offscreen only.

$ ./float --show ...

To enable QtWebEngine's Chromium debugging, set the QTWEBENGINE_CHROMIUM_FLAGS environment variable.

QTWEBENGINE_CHROMIUM_FLAGS="--enable-logging --log-level=0 --v=1"

And for advanced debugging, you can enable Chromium's developer tools interface via the QTWEBENGINE_REMOTE_DEBUGGING environment variable.

QTWEBENGINE_REMOTE_DEBUGGING=9001

Then visit http://127.0.0.1:9001/ in a Chromium-based browser (such as Google Chrome).

All of the above debug options can be combined too.

QTWEBENGINE_CHROMIUM_FLAGS="--enable-logging --log-level=0 --v=1" \
QTWEBENGINE_REMOTE_DEBUGGING=9001 \
QT_LOGGING_RULES="*=true"
./float -d ...
