Using Karoo 2 for indoor training ONLY with power meter

[albinn]

Hi,

I have a pedal based power meter which also gives cadence, and a dumb direct drive trainer with fixed resistance.

I would like to use the Karoo simply to register power, heart rate and cadence over time, my intervals.

When I have tried this, selecting the pre-defined "Indoor with power" mode, the resulting fit file does not register the time and power. I guess the Karoo is still trying to register the GPS movements and since I am not moving it does not save the information. I've turned off autopause.

How do I get the Karoo to understand that I do not want to log any distance or speed, but simply my power and other data over a timeline?

https://www.strava.com/activities/6347980335 see attached for example. This training was around 45 minutes and I could see the data on the Karoo continously during the session, but no data is saved afterwards.

Thankful for suggestions!

Same question! Hopefully someone knows.

Random thought…Have you tried turning off GPS or turning on airplane mode?

You might need to add a cheap wheel speed sensor or something. Strava may reject the "ride" because it's 0 miles? What does the Karoo/HH dashboard show? Have you tried downloading the FIT file and putting it into another service (TrainingPeaks, Golden Cheetah (an app not a service), etc.) to see if anything got recorded there? I would think the power numbers should be in the FIT file, but perhaps nothing knows how to display it properly without either a GPS track or some sort of indication of distance traveled?

Mine works OK using Mangene cadence and speed sensors.
$25-30 for a pair on eBay. reliable stable, battery lasts >a year
I had to disable the Karoo GPS, which gets distance priority otherwise.

So used to doing it manually ,I haven't noticed if the new profile settings would do that for me .

- We’ve fixed a bug with Indoor Profiles that could cause them to have a single line of GPS data at the beginning of the FIT file, causing them to upload improperly to 3rd parties (e.g. Strava). Now, Indoor rides will be 100% GPS-free.
