This morning I tried the new code from #3280 but I don't think is working. In the test I was pedaling at around 55-60 rpm.
I attach the log:
debug-Fri_Mar_7_08_55_13_2025.log

is this log from the last commit that i did?

yes it is but yes the cadence seems high. maybe the double or don't you think?

It could be that is doubled. We can give it a shot.

ok let me know, tonight i can't sleep :D

I made another test. I think is linked to the speed because when I stop pedaling it keeps going slowly down with the speed. Maybe the cadence is not transmitted at all...
I forgot to try to gear change. I will make another test later.

I will start to take a look on the brench treadmill-gpio.

Is it possible to tell QZ to calculate cadence from the speed transmitted by the trainer if I set a specific gear and use virtual shifting as if I had a Zwift Cog?

Thanks. Then if you can also tell me how to set it up would be great, because I know there is the section for virtual shifting in Wahoo options, but I don't understand the meaning of Virtual Wheel Size. It will impact the calculated cadence? The trainer outputs speed, but how is calculated? The trainer has to have a wheel size in mind.
The other settings are clear.

Your trainer doesn't have the Bluetooth capabilities to use the wahoo options

You have only to use the gear gain setting to make it harder or softer with the gear tile or zwift click or zwift play

Ah ok. I thought all trainers that support Zwift virtual shifting would have the bluetooth capabilities to do this. I gave it a quick try and it seems to do something, but maybe in the wrong way...

No issues. I want just to understand if wahoo options are only for wahoo trainers or are for all trainers that are compatible with virtual shifting in Zwift. https://zwiftinsider.com/virtual-shifting-support-status/
There is a way to tell to QZ to calculate the cadence based on speed and based on Chainring Size, Cog Size and (I think is needed also but maybe I'm wrong) Virtual Wheel Size?
My goal is to have some cadence reading until I manage to use the GPIO with the hall sensor to measure the real cadence.
Tell me if I'm going in the wrong direction.
Thanks

No as I said the wahoo options it's only for compatible trainers that have the possibility to receive wheel diamater configurations. Are you aware if your trainer does?

Not at the moment. But I can implement it. This week I'm in Germany the whole week so I can't.

Got it

Tell me if I'm going in the wrong direction.
Thanks

If you want I can do a quick branch to show you how to set the cadence quickly from the speed while I'm on the car

Ah ok. I will check if it can. I was thinking the point was the compatibility with Zwift Virtual shifting, not with wheel diameter configurations.

If you can, that would be great. I don't want to bother you too much.

Cool! I start to understand the code. 😺
Now I have only to calculate/find the right ratio. Thanks a lot.

@geel97 Any news?

I'm using now the cadence calculated from the speed. Maybe is not the best but for now it works. For the future the feature can be added to the app via #3292 .
I'm really busy in this period as is the last month with a bit of sunlight here in Concordia Station. When I will have a bit of time I will take in hand again the PR #3292 so that this work will be usefull for all the comunity.
