What max watts on dumb trainer from list

Hey…I’m re-taking again the topic bcs I still have one doubt…I understand that tacx booster (dumb trainer) with sensors should work with z-power, but with this trainer you can shift the resistance between 10 different levels.

how this is informed into Zwift?

is it that you should fiix the resistance in this is why the max power is limited to the corresponding curve based on the graph above?

thanks for response…if someone have any :slight_smile:
