Hey, guys. Hello, Alex!!! I did it!!! I finally almost got what I needed from the interaction of all my devices and gadgets regarding stats. My trainerbike is now in ERG mode and controls the load from your app from my iPad. In addition, the workout is recorded and logged by the Garmin watch and its performance by performance is displayed in Garmin Connect, keeping all the stats I need on power, cadence, HR, distance and speed. If this is relevant and necessary for anyone, I can provide more details on how I did it.
