Suunto HRV values from *.fit file not prossed by GC

[Joni-Pekka Kurronen]

Suunto .fit has HRV values if any suunto device or app

directly used whit EKG device like suunto movesense !

Anayway build 5010 did not detected HRV values.

Have not digged why it dose not accept.

Documentation says suunto uses .slm files but

app gives out .fit !

The HRV R-R data is parsed and available- see the HRV tab under Data

hi,

I found installation problem whit python.

I have now updated python to 3.14 but

still HRV Chart gives unicode error,...

... could be this probleam ? https://stackoverflow.com/questions/14630288/unicodeencodeerror-charmap-codec-cant-encode-character-maps-to-undefined

And problem whit golden cheetah is that it dose not detect

installed python from directory:

C:\Users\Joni-\AppData\Local\Programs\Python\Python314\

And it autodetects most likely anaconda installed or other rather old 3.7 python!

So most likely HRV, importing R-R from .fit suunto dose work but

my installation and golden cheetah can get agreement what python to use

and that causes character maps problem.

How to correct this problem ???

You can check HRV data import going to Data > Raw Data > HRV, for further details see https://github.com/GoldenCheetah/GoldenCheetah/wiki/HRV

You don't need Python for HRV but, if you want to use it you should read  https://github.com/GoldenCheetah/GoldenCheetah/wiki/UG_Special-Topics_Working-with-Python
