Saw some earlier threads on this but they didn't really answer my question,
I bought a second cadence sensor for a bike I leave on the trainer full time. Each time I take out the street bike it seems to be finding the trainer sensor first, and if I miss the alert saying "do you want to switch sensors" I have to rotate through all the menus to select the street sensor and disable/re-enable to get it to track the correct one.
I suspect part of the problem is the trainer sensor (magene S3+) is in an always on state where the street sensor (Garmin) needs to be woken up.
To the point of all this - is there a way to prioritize one sensor over the other so that the 520 always recognizes the street bike sensor first?
