I would like virtual power. Will you add it? (COMPLETED)

I am sure I am going to ask so really dumb questions but I am totally new to indoor cycling. I got given a basic wheel on trainer which I have put my old road bike on. I have no power meter. I have a basic sensor that can do speed if on wheel or cadence on crank. I have a heart rate monitor. Is this enough to use Trainerday for workouts? How should I set things up? Sorry for the basic questions but have no clue. Thanks in advance
