No, if you want a visual smoothing e.g. over 3 seconds, you have to set that in the settings of the TR app.
The smoothing done by the Kickr completely ignores the actual watts and just sends the target watts for the app to display. It basically lies to you. That power graph is impossibly smooth. No human can achieve that.

You still have to do the work and put out the required watts, but the graph is totally useless.
