PyCycle - workout file on Wahoo

Hello,
Together with my friend we create application for Wahoo - PyCycle. Application can download workouts from intervals.icu and convert to .FIT file extension. Wahoo can red this file as workout (This avoids the manual downloading of workouts from intervals.icu then uploading to TrainerDay and then to TrainingPeak). PyCycle downloads today’s training and all trainings scheduled for 2 weeks ahead. This project is beeing developed in free time.

FIT workout file supports cadence but… Wahoo doesn’t support cadence target on this type of file. We were able to add cadences to workouts but under the field “Target BPM”. Workouts can be 5-10s longer because FIT file dosen’t support two targets (e.g. power and cadence) and we must create 1s segments to display cadence (on Target BPM field):

What you need:

Instalation:

  1. Download the files indicated above
  2. Install Java version 8 update 301
  3. Install Python on version 3.9.7
  4. Run the python installer again and select Modify. On the Optional Features select “pip” and on Advanced Option select “Add Python to environment variables”

This certainly looks interesting.
Does it work with OpenJDK or only Oracle Java?

It work with OpenJDK - testing on version 8u262-b10 on Windows 11 x64

We are update PyCycle to version 1.2.0
Changelog:

Does Step 15 require that I plug my Wahoo USB to the computer running this agent?

Can this also generate Zwift Workout compatible files (unsure if conversion required) and publish them to some folder as well?
