Speed vs cadence / hill grades about gpedal HOT 6 CLOSED

I am a bit confused between speed and cadence - today the cadence magnet was not lined up and it seemed to use the speed only (no RPMs were displayed). Is this the expected behavior? If so it should solve the first part of my problem - just disable cadence.

A little back story here. GPedal was primarily written to be driven by Bluetooth power meters (not cadence and speed sensors). I recently wedged in the ability to derive a power value from only a speed sensor assuming you were riding on a Cyclops Magneto dumb trainer. To pull that off I used data from these blog posts: https://machiine.com/2018/how-accurate-is-zwifts-power-estimate-for-classic-trainers/ . This is similar to how Zwift handles dumb trainers. But I only have a power curve for the one trainer v.s. the hundreds that Zwift supports. GPedal's support for reading in speed data (not cadence) is a little incomplete right now.

So if you're using the "Cycleops Magneto Power Curve" Power Meter then what you're seeing is correct. It will try to read in speed data to derive a power value. The cadence value is only used for display purposes. I wedged in the ability to read in speed values from cadence sensors that broadcast both data points. Which was a quick hack for sure.

Does that help explain the situation ?

That helps a lot. I am not looking for the power reading to be exact - more that a higher gear translates to a faster speed. I think this will work. I will continue looking into methods for adjusting the resistance for hills. It sounds like there are at least a few others interested in that,

If you don't mind me asking which trainer are you on? I might be able to put together a power curve for it.

Sure, that would be great - it is a Sportneer Bike Trainer . It has a resistance setting so I am not sure how that factors in. I am also using the Wahoo Speed / Cadence sensor which works great with the application.

Ok, I checked online ( google 😊 ) and I couldn't find any power curve/data available for this trainer. So we're out of luck.
