I heard from some of Levi's co-authors that Rossi played less of a role in Lugano. I don't know what to make of that, or whether to believe it now, after all that has happened.
What Rossi did in Lugano is described in the report that the Professors who conducted the test wrote:
"The dummy reactor was switched on at 12:20 PM of 24 February 2014 by Andrea Rossi who gradually brought it to the power level requested by us. Rossi later intervened to switch off the dummy, and in the following subsequent operations on the E-Cat: charge insertion, reactor startup, reactor shutdown and powder charge extraction. Throughout the test, no further intervention or interference on his part occurred; moreover, all phases of the test were monitored directly by the collaboration."
The authors clearly say that they have monitored his interventions and have also decided at least some of them ("... power level requested by us"), maybe all of them. Rossi's presence during the test is understandable, considering that he had to protect his discovery and legitimate secrets. No one would ever lose sight of an object that may be worth a fortune, especially if it is placed in a room that is not necessarily safe (they were in a Swiss premises .... not quite a safe deposit box). As for his interventions, it seems that they are limited to essential things, according to the Professors, who agreed to make that kind of test and signed the article. I think they would never have done it if they had felt themselves at the mercy of Rossi.
