Man, that is fine print! I am having the same issues on new Wahoo Kickr. Wattage is impossible to keep consistent and when my son rides it for FTP testing it spikes 100’s of points at a time with no different effort. I can’t believe how many lame excuses are used: pet hair covering sensor, dust, too much light, do this or do that…I think there is a major disconnect or software issues.
My son did the FTP test at another house, same Swift account, used a Kinetic Road trainer (Green one) and had no issues… We used the Wahoo app and it works. So is there a communication link issue between Swift and Wahoo?
