The Vortex over bluetooth should work for power, which you can pair over bluetooth or ANT+. The Ride Sense you can pair over ANT+. Feel free to mix and match as you want. I typically go for Bluetooth on Mac as we read/send commands at a slightly higher frequency on some trainers, so that’s what I’d try first for the Vortex.
Yes, add the vortex as controllable trainer (it’ll also be added as your power sensor as the vortex sends power data), then separately pair your cadence sensor if you want. The cadence sensor is totally optional.
