So I just acquired a RTL515. I bought it because of the peloton mode. I already own a RTL510, which I plan to relegate to my commute/cross bike as I tend not to do group rides with that bike. I don't plan to use a separate bike computer for each Varia radar so both are now paired with my Edge 530. The issue is when I start the timer on the Edge 530, it turns on both RTL515 and RTL510 (when they are both in range of the bike computer).
What I would like, without having to manually disable one of the Varia radar, is to associate each Varia radar with a specific activity profile. That way, only one Varia radar is enabled when I start the timer.
