As you can see from (3) and (4), I do have data coming from my Tymewear.
I hope someone can help me out 
Thanks in advance!

The VE data that you have a t the top (3) should be the same as Ventilation (1). If you want to double check that, search the plots for tyme, and you will see that you get Ventialtion and Respiration Rate. Otherwise, if you simply search for “Respiration”, that will also get you breath rate.
HI
Thanks for the quick response.
But where/how are you adding the plot ?
Go to Charts at the bottom of the activity Timeline tab, then click on Custom Streams - Looking glass, and search for Tyme
Thank !, but I already have theese streams
You do not need to add custom streams for these anymore, they are built in. Search for VT, VE and respiration in the normal (not custom) charts dialog:
Averages are also available for the intervals:
Tymewear respiration data is favoured over data derived by Garmin et al from heart rate.
Thanks David !
But I already have added the fields in charts, but still now Ventilation or Breat Rate showing
Which activity are you looking at?
Aha I finally get it. You are using a custom activity chart from @Inigo_Tolosa
That will need to be updated to use the built in streams.
What you can do (without any coding) is add a custom trace chart. Click “Charts” and the plus button:
Then add whatever traces you like, with moving averages etc..
@Inigo_Tolosa These are the built in streams. You could update your chart to look for these if the custom ones are not present:
{ id: 'respiration', text: 'Respiration' },
{ id: 'tidal_volume', text: 'VT (ml/br)' },
{ id: 'tidal_volume_min', text: 'VE (L/min)' },
Oh !..thanks again David !
Hi @david
I’m trying to achieve the same with no luck, VT and VE are not shown in my activity from Fri 12 Sep 2025. Can you help me?
Thank you
That activity is from Strava and their API doesn’t pass on anything beyond the usual power, heart rate and so on.
Thank you for your quick response, I will dig into changing it so the data syncs from Garmin Connect.
yes, I can see it now. Thank you.
I just received my Tymewear strap, performed the initial threshold test using the Tymewear app to control my Wahoo Kikr Core in erg mode, exported the FIT file from the Tymewear app, and uploaded it to intervals. Following the instructions above, I can see HR, VT, and VE for this activity, but power is not shown. Cadence is shown, but it’s wrong (constant value of 208). On the advice of Tymewear customer support, I downloaded Golden Cheetah and imported the FIt file into GC. I can see in GC that there is a stream called tyme_power, which appears to contain the correct power numbers. Is there some way to associate this field with power in intervals? (There’s also a field called tyme_bike_cadence, which appears to show the actual cadence divided by two. And there are a variety of other data fields with tyme_ prepended.)
Hi, I just received the tymewear few days ago, and created a script similar to the one discussed here earlier. If you want give it a try, the script is also publicly available, so you can tweak it by yourself. It displays relative numbers - HRR and BRR - so in the source, you have to setup your values for Max HR and max BR (probably there is a way how to get those from user profile, I didn’t bother yet 
).
The name is “Tymewear BRR vs HRR %”
I have an issue with the altitude? Could you advise? Thank you!
try to get the new version - I fixed that
