Spitting into the wind here, I know…
I’ve just been putting up with this annoyance, and I know there’s no point in reporting it, but here goes…
I can’t pair my Kickr as a controllable trainer unless I first pair it as a power sensor. If I have my Assioma pedals selected as the power sensor, no controllable trainers show up. Once paired as a controllable trainer, I can select a different power sensor.
Similarly, I can’t pair my Assioma pedals as a cadence sensor unless I first pair them as a power sensor. If I have my Kickr paired as a power sensor, no cadence sensors show up. Once paired as a cadence sensor, I can select a different power sensor.
So, to get everything paired, I have to switch my power sensor at least once. It’s mildly annoying.
It wasn’t always this way. Zwift used to default to my previous sensor pairings without any fiddling.
BLE on Windows, BTW.
