I have a windows laptop and an AppleTV 4K + TV.
I run SYSTM on the windows laptop with an ANT USB dongle (from Garmin btw). I then pair my smart trainer (tacx neo) with ANT & SYSTM as I normally do.
On the AppleTV I run Zwift. I pair with bluetooth. Select “power source” and “cadence”, but disable “Controllable”. This way Zwift won’t try to control the trainer (hills etc). SYSTM will control the trainer. Zwift responds correctly to to power I put in the pedals.
Now I can do normal SYSTM workouts and get entertained by the zwift graphics. You can even do zwift races while you do an ERG workout in SYSTM.
