I have raised this a few times so i fear the answer is no but will you ever be able to select a different power meter and/or cadence sensor to the controllable trainer in the android app?
You can in the PC version.
Both show up in the pairing section but if you select the controllable trainer you have to have that as the power source and cadence as well or it just shows no signal or reports zero watts.
I know the power reading from my trainer are wrong but my power meter is good so it is a bit of a deal breaker for me using the android app.
