Re: FAQ: Tymewear Datashift and timestamp fixes

Thanks thats definitely a workaround.

No idea where it gets timestamp and why it's out and also not even always out by the same amount.

I'm away in Spain riding soon so will have a much bigger play with it.
Might venture outside this weekend but its freezing here 🤣

Re: Does the Merge Tool also combine developer fields from two FIT files?

I'm more confused now.

SCR-20260211-pidl.png


2 more files, this time I think they are more like 30 minutes out. The 2 marked points are maximum breathing at the top of the climb and the altitude itself showing the climb.

I've attached fit files.

Re: Does the Merge Tool also combine developer fields from two FIT files?

Hiya, it's a weird one as the tymewear device is a bluetooth sensor, so not sure where it would get a timestamp from, the files recorded from it are on the iPhone app and I would assume thats uses the iP{hone for time so no reason it should be off?

I'm going to get a separate pair and see if they ...

Re: Does the Merge Tool also combine developer fields from two FIT files?

the few I've go to work are around 14 minutes, they only seem to work at all if I crop the longer tyemwear file to the same length as the Karoo file.

That could be me doing something wrong with merging

To add the breathing charts you need to.

go to activity, click on charts at the bottom, search ...

Re: Does the Merge Tool also combine developer fields from two FIT files?

I tired it a bunch of times but it only sort of works, the data combines but the breathing data is always out by about 14 minutes, no idea why.

If there was a way to time shift it'd work but as it ease the breathing data doesn't align with effort level

Re: Does the Merge Tool also combine developer fields from two FIT files?

Thanks for the info.

I've merged another activity, this time main data recorded with Karoo, Tymewear is recorded by the strap then synced back to their phone app for upload, time is out again so I assume Tymewear is the issue, not sure how to fix.

Is time shift possible?

The dodgy HR bit in in ...

Re: Does the Merge Tool also combine developer fields from two FIT files?

Hey, I become a donor and tried it. It's very nearly there.

It has combined the data an d the value look correct but having tried 2 activities the data is about 6 minutes out in terms of timestamp.

The tymewear breathing data is too soon.

See below, you can see were power is applied and HR rate ...

Re: Does the Merge Tool also combine developer fields from two FIT files?

Just to say Tymewear has updated their dashboard and removed the ability to merge completely which is unbelievable. So if you can get this working I think it'll be every useful to a lot of customers.

Happy Thanks giving.

I am a premium TP member, just to do a free account to see if it works but if gives you 14 days premium free :(

You could test on intervals.icu following the below image. You upload file and view it, click on charts and search for VENT and then add the one that comes up. There loads already made ...

Re: Does the Merge Tool also combine developer fields from two FIT files?

bit more info having done some digging.

I've compared 2 timestamps and although GOTOES has merged the data the figures are all wrong which is probably why it is all wrong in Intervals and TP.

Re: Does the Merge Tool also combine developer fields from two FIT files?

hi the merged file doesn't work, it has some data spikes but is missing the actual data and the spikes are 100x higher than possible.

Nothing shows in Garmin buyt I guess they don't support it and I don't use Garmin anyway.

Both Intervals and Trainingpeaks do support all the Tymewear fields.

The ...

Re: Does the Merge Tool also combine developer fields from two FIT files?

Hi

Lets see if this helps.
This a CX race from yesterday.

Karoo would be the "master" even though the time elapsed is shorter as its the actual race.
To record the tymewear data, you start an activity on your phone, leave it in the car then finish it and upload once back at car, therefor the ...

Re: Does the Merge Tool also combine developer fields from two FIT files?

I’ve just come across this post as I’m to looking for a solution to merge an original fit file from either TrainingPeaks virtual or hammerhead Karoo with a tymewear fit file.

The issues are. Tymewear has merge facility on their own website but it strips all gps data from merged file. Then when ...
