Thanks for following up. Thought about it a bit and realized the reason I don’t see the second power source is because the file is coming from Strava, not directly from TP Virtual. I just manually uploaded the file from TP Virtual and the second power source is there. So now I understand what is going on and how this works.
BTW, from the indievelo days they recommended a website called dualrecording.com which is great for comparing the output from two different power sources. That is what I have used in the past for my indievelo/TP Virtual rides since it is interesting to see how closely the two power sources correlate.
You can choose to compare 2 power streams from one single FIT file or from multiple FIT files. Align them and analyse.
But given the recent addition in Intervals and the plans that David has to make in-depth analysis of the second stream possible, it will not have much use anymore for FIT files with multiple power streams.
I can’t find the field Avg Power2 (and other related) and also can’t get the Custom field to work since it now is a native stream. Or I’m doing it wrong…I’d like to get an idea of the avg difference.
Following script works fine:
{
let temp = streams.get(“secondary_power”).data
let tot = 0
let c = 0
for (let i = interval.start_index; i < interval.end_index; i++) {
let v = temp[i]
if (v) {
tot += v
++c
}
}
I may have missed this - I’ve managed to set up dual recording and display on the main graph, which is great. The question that came to mind today when uploading a file to dualrecording.com to check things over was…since intervals already has the data, can I put it on a tab on every activity by default? Reading around I think the answer is no, but if it is possible it’d be a great thing to add!
Not sure if this answers your question but if 2 power streams are available, Intervals can display both on a Timeline chart. This one also has Workout Power.
Perfect! I was wondering how to add the secondary on the power tab (i managed to set up the timeline to show both a while back) but on looking closer I see clicking Options > Streams gives a checkbox for power2 - brilliant!
Intervals is way ahead of most other options having all these things to play with
Garmin users…
This app was not updates since 2023 and does formally not support many news Edge devices…
Is there a new/alternative IQ field or another solution to dual-record two power meters on a recent Garmin Edge?
Not to my knowledge.
I contacted the dev of this IQ field and asked to make it available for Edge 840, which it isn’t, but he responded that he’s no longer actively supporting it by lack of time.
And I haven’t found anything else with that functionality for my Edge 840 device.
Hi, today i did a ride on biketerra it recorded my power via my home trainer + my pedals favero assioma
On icu i have two curves one called power and the other called power2, how do i know which one is associated with which powermeter ?
