Hey Lindsay - It is the ANT+ CycleOps sensor. It for sure is not an issue with the unit sleeping. Of course it can auto pair a unit that isn’t broadcasting. Both the Kickr and my Wahoo HR monitor are “saved” in the pairing menu. When I “activate” them they are paired, and are shown as paired.
So to test this, I pedal the bike, spin the Kickr, and put on the HR before starting Zwift. The HR and trainer are paired and ready to go.
I have to click on the pair device, and then click on the sc sensor which is always right there in the device choice menu.
But I have to choose it each time.
There is no delay - and I don’t have trouble with Zwift ever finding it. It is always there in the second level menu.
This is not an issue in either TrainerRoad, Wahoo Fitness, CycleOps, or my Polar V800.
Thank you for checking up on this - I think your support is really great and responsive!!
