[SOLVED] Intervals.icu can not handle dual-recorded fit files?

[SIMMN]

I did a quick 2-min test in TrainingPeaks virtual (IndieVelo) App on ipad to dual record power data from my trainer as well as my power meter. The data is then uploaded through Strava and synced to intervals.icu.

• If I download the original fit file from Strava, the file has both power data.
• If I download the fit file from intervals.icu from activity page, it only has power data from only one source.
• If I uploaded the original fit file (downloaded from Strava) to intervals.icu manually, it displays the activity properly but when I tried to download a fit file from this activity, I got error below in browser.

{"status":422,"error":"Unhandled stream secondary_power"}

From what I read in the forum, dual-recorded activity is supported in intervals.icu…So what did I wrong???

Intervals gets the FIT file through Strava´s API and that file is modified by Strava. Read ´stripped´ from anything not standard.
If you download the original from Strava, you get the original full featured file. Manual upload to Intervals has everything.
In the Actions menu, check Settings and under Power you will see a selection for the ´default´ power stream to use. The name of the second power stream should be displayed.
I think the TP second stream should already be handled correctly and can be found in Intervals as ´power2´.

Thanks for the info and it does make sense (another reason to get ride of Strava…).

But I followed your instruction to select the default power and I assume you mean the “Power Field” for selecting the power data, right? Screenshot below. If so, any chance I could have both power data displayed at the same time?

You’re alry there. See the pencil icon on the “Power Field Power” that will enable you to select the DEFAULT power data you want.

In any case. Secondary power is supported. In fact, any custom fields is supported by intervals. (You just have to create the code to recognize the field if it’s not alry been done by others).

What do you want to do anyway? You want change the default power? You want to view the 2nd power as a stream (chart) ?

In short, I would like to see the 2nd power in the graph (overlay with the 1st power or below the 1st power) under the Activity TIMELINE tab if there are power data recorded from two sources.

Secondary power trace added

If you are using 2 power meters (or Garmin and Stryd for runners) or training indoors with software that supports trainer power and power meter power, it is now easy to compare those on Intervals.icu. Do Actions → Settings and click “Power Field” to choose the primary one used for activity analysis etc.: [Screenshot 2025-01-14 at 14.06.55] [Screenshot 2025-01-14 at 14.04.52] The power field you have selected is called “Power” and the other “Power2”. Click “Charts” under the activity timeli…

Thanks for the info!!!

{"status":422,"error":"Unhandled stream secondary_power"}

I have fixed this. The secondary_power stream is now included in the Intervals.icu generated fit file.

Thanks for the quick execution!
