I've got a Wahoo RPMcadence sensor connected to my Forerunner 255 and the sensor is attached to my crank arm on indoor bike. The watch connects to the sensor when I start an indoor bike workout, but I see no data for the sensor when I scroll through the windows. Is there a way to see the cadence in this workout or is really only useful for the outdoor cycling setting? Likewise, it looks like it can show a speed value in the indoor workout, so I'm guessing if I can figure out how to get my wheel circumference into the system, this may get me there? Last caveat, this is a fully stationary cheapo-exercise bike with a fixed heavy flywheel, so not a road bike on an indoor trainer.
I really don't care so much about speed or distance, as I just want to know what my pacing is like based on cadence and heart rate.
