I have read a few threads in the forum regarding ’ No Signal’ on Kurt Kinetic trainers but I am having the same issue with an Interchange speed and cadence sensor.
I have been using it quite happily since the start of the year but as of the last month or so it will not connect properly. The ‘Paired devices’ screen shows the interchange and the Elite power fluid red roller turbo on the respective speed and cadence boxes, the BLE-phone is happily sending out its waves on the screen picture but the message shows ‘No Signal’.
I have tried two different phones and a tablet and even swapped out the battery in the sensor but nothing has worked.
I have spoken with the Zwift tech team and they have advised me that this is a current issue with no solve date as of yet and no workaround for the problem.
Not sure if anyone else is having similar issues but may answer a couple of questions and stop them pulling there kit apart looking for the gremlin.
