This is for trainerroad, but should work similar to Zwift:

You had the little "Joule" gps unit that controls the Cycleops. That connected to the Powertap on there via ant+. Then, Zwift could somehow see the Powertap/Cycleops using the Joule GPS as it had bluetooth and I used Zwift on my phone. Then I'd run a little video adapter cable to the TV in the gym.
On the Joule gps unit I would just manually adjust the ERG power command and "pretend" in Zwift.
Some folks got fancy enough to somehow get it to work with either virtual gears or added a real RD to it somehow. I can't find it now. Pretty sure a certain version of all of it could have Zwift give a command to the Cycleops and you used the virtual gears on the Joule gps somehow to change gears.
I never got that far as I didn't own the bike, it was the work gym's.
Ah, I never thought about the newer Joule GPS head units having Bluetooth and being able to connect to Zwift running on a phone. The proprietary Cycleops ANT protocol prevents direct connection to the bike, but that the ANT power (and cadence, presumably) signal gets translated to and transmitted in BT in real time is fascinating, and I wish I’d known about that years ago. It still may be handy for my studio, though...
