The resistance does not correspond to the displayed wattage

Bugs and Support

Hello,
since the latest update I have had the impression that my roller trainer is creating more resistance than before. The displayed wattage does not fluctuate, does not go to 0 and does not sporadically peak, which is why I assume a stable connection. During my workouts based on the FTP value, however, I had to reduce it to 80% because even the warm-up phases already feel like 350 watts, although only 180 watts are displayed. My smarttrainer doesn’t block either, i.e. the hub continues to turn freely when I’m not pedaling, so there’s no fault here either.

I use a Van Rysel D900 as a roller trainer, which as far as I know does not allow manual calibration.

Perhaps someone has the same problem and may have already found a solution. I am open to any tips. Thank you.

Solution addendum:

In my case, the Van Rysel smart trainer could be calibrated using the OnelapFit app. A second calibration was also possible using Zwift (I had never noticed this before). On the home screen, while the devices are connecting to the app, there is a tool symbol next to the roller trainer. This can be used to calibrate again, but this time directly in Zwift. Unfortunately, I cannot say how the results differ, as only “Calibration completed successfully” is displayed.
