A tool for exporting training sessions from Polar Flow.
$ git clone [email protected]:asib/polar-flow-export.git
$ cd polar-flow-export
$ python -m virtualenv env
$ . env/bin/activate
(env)$ pip install -r requirements.txtYou also need to download ChromeDriver if you don't have it already from
https://chromedriver.chromium.org/downloads and put it somewhere in your PATH.
In Ubuntu, you can install with: sudo apt install chromium-chromedriver. Make
sure that the version of ChromeDriver installed is a match for the version of
Chromium you have installed, or Selenium will fail to start.
(env)$ python polar-export.py <username> <password> <month> <year> <output_dir>The tool will save sessions into the output directory, using the default filename provided by Polar.
Annoyingly, the Polar Accesslink API doesn't provide access to historical training data, only new sessions. This means that if you've just created, for example, a Strava account, you have to manually export and upload each session in order to have all your old data show on your Strava account. Even more annoyingly, all the existing Polar Flow export tools I found were clearly written prior to an extensive rewrite of the website, which now uses React under the hood. Therefore, they no longer work.
I originally wanted to use https://flow.polar.com/diary/training-list to fetch
all the IDs, but they're cleverly hidden inside onClick attributes that have
prebound arguments, so I got tired of trying this route (may revisit later - using
React DevTools, it's possible to inspect them and find the ID under [[BoundArgs]],
so perhaps possible to do programatically using Selenium).
Instead, the IDs are available on https://flow.polar.com/diary, but the page
is only rendered properly with Javascript, so simply using requests wouldn't
work, which is why I wrote this tool using Selenium.
Anyway, rant over.
