2 years ago Do you feel the resistance change in your legs when you encounter this issue? I am sure you are as going from ~150W to ~220W is quite a bit.
If you don't feel the resistance change in your legs, I am wondering if this has to do with the mechanical part of the dial or perhaps the IC4 bike itself is reporting incorrect power? I think Gymnasticon works on just retransmitting the values spit out by the bike's computer and doesn't alter them unless you put the power-scale factors in the config file.
I don't know how IC4 bike works, but I am guessing it is similar to the Flywheel spin bike I have. On mine, the resistance is changed using a dial which is tied to a cable to change the resistance while riding. Sometimes that cable gets stuck in the housing or doesn't release/pull all the way when I make small changes to the dial (like going from 40 to 42). If this happens I just make larger changes on the dial until I see desired power on my Garmin head unit (It usually overshoots and I have to dial it back tho). If you suspect that it is a mechanical issue, have you tried changing the resistance to a higher value to see if your issue persists?

So I have the gymnasticon running with ANT+ on a RPi Zero W, connecting to IC4.
IC4 has difficulty levels from 1-100. When I start pedalling at 32 difficulty, the reported power is about 140-160, which is fine. But when I start doing 3-minute intervals, where I switch the difficulty between 32 and 55, at some point gymnasticon reports pervious power as if I did not change the difficulty.
That is, if I pedal for 3 minutes at 32 the reported power is 140-160. Then I change the power to 55, but the reported power stays at 140-160 (should be 200-230). During half an hour of training, I need to restart the RPi once. Then the power is reported correctly again. This is not happening each time. On average, once every half an hour from what I have seen so far.
