I was wondering if you could help. I recently acquired a used Kickr and tried to set it up last night. Although it paired on both the Wahoo and TR app via Bluetooth (and showed a strong signal in both), it didn’t register any speed or power when I started spinning the pedals.
It’s entirely likely that it may be a chronic issue - I was given it by my mate as it had a fault on it that meant it overheated at low cadences (I don’t really do any low cadence work), so it may have just given up the ghost (and it’s outside of warranty, so I can’t get it replaced). But the ~30secs I spent on it were amazing compared to my Vortex, so I’d jump at any chance of fixing it!
