I’ve got a Kickr and use it with my Apple TV (sensors via the companion app).
As of a few days ago, Zwift seems to have lost the ability to control the watts on my Kickr.
It started this weekend … I was doing a structured workout and Zwift lost connection with all my sensors. I figured something went wrong with the companion app, so I restarted.
After a while, I was able to get the sensor connections back up.
Unfortunately, Zwift didn’t appear to be able to control my Kickr. The workout was calling for a specific wattage but wouldn’t control the Kickr to make me put out that wattage.
I tried force closing the companion app & Zwift on the ATV. I tried restarting my iPhone & the ATV. I also tried uninstalling & reinstalling both the companion app and Zwift on my phone & the ATV.
I also tried doing a spindown calibration of the Kickr on the ATV, but it never detected a speed less than 2 mph, even with the kickr totally idle. Spindown in the Wahoo app worked fine.
The MacOS version of Zwift has no problem controlling the kickr.
One other thing … yesterday I upgraded my Kickr to the 2018 version (my wife gets my old Kickr) and saw the exact same behavior, so I’m pretty confident it’s not related to the Kickr.
