regular Kickr estimates Cadence from variation of power during your pedal stroke.

But if you also use the Zwift handlebar controllers, that's more BT channels. Also, I don't think all trainers necessarily combine data sources into one Bluetooth channel. The limited number of Bluetooth channels on the AppleTV is an issue, though not necessarily for all trainers and all users situations.
