I recently attempted to perform a calibration of my Kenetic InRide 3 power sensor but the app would not detect sensor.
I use android.
I checked Kenetics support pages and I saw there were a lot of people complaining of the same issue with the Android platform.
IPhone seems fine.
I uninstalled the program and deleted the data and storage when prompted to do so.
I re installed the program and everything worked as expected.
I also tried using the InRide sensor as a classic trainer.
In that case, the roller on the trainer is the “wheel” and when I started to pedal, it put my speed at 101 mph!
Good luck.
Hope this helps if your having problems.
