I use a Stages power meter when cycling outdoors. My Wahoo KICKR’s power is off and not by a constant amount either. I know this is all relative, but it would be nice if Zwift could find a way to allow the Stages power meter to control the Wahoo KICKR’s resistance. I also use TrainerRoad for example, and they implemented just this (not just for Stages, but in general) feature, which is outstanding, as my power inside and outside match. See this link: http://support.trainerroad.com/hc/en-us/articles/204631294-PowerMatch-Using-Power-Meters-with-Electronic-Trainers
Does Zwift plan on doing something similar? That would be a great feature to have.
