Dual Power Recording Now Supported (BreakAway : Indoor Training iOS)

[app4g]

I recently read that IndieVelo is doing dual power recording into the FIT file. Can anyone share how this is being done? (Developer Field?) I know it’s supported by Intervals.icu.

I would like to also implement this if possible.

Have completed support for addition of 2nd PowerMeter data to be recorded into the FIT File using Developer Fields.

let powerAltName  = powerPriority == 0 ? "TrainerPower" :
                    powerPriority == 1 ? "PMPower"      :
                    powerPriority == 2 ? "SpeedPower"   : "RandomPower"

Using this as a guide, am able to create this

Custom activity streams

Here is an example. I created a “PM Power” field for the “Powermeter Power” watts field that indieVelo dual records. I chose “watts” as the units: [Screenshot 2023-07-20 at 07.49.10] Now I can create a custom chart comparing the power traces. It is clear that my trainer needs some calibration. I only just bought it and wasn’t about to fuss around with calibration with exciting TDF on the go. [Screenshot 2023-07-20 at 07.55.06]

Have added 2 new Custom Streams for these.

Not sure if custom charts can be shared. But Here’s now it looks.

An Example of a longer workout. (This is a HR Based workout. So perhaps not so representative. I’ll need to do a Power Based workout.)

Edit: Added Workout HR and Actual HR overlaid to see how the app is controlling the power to stay at the prescribed workout HR
