I’d really like zwift to offer a basic Linux distro that could be installed on a raspberry pi zero that would act as a dedicated Bluetooth / ANT+ gateway that can be used by Apple TV users instead of using the companion app.
The pi would receive data from sensors and feed it to the zwift app on atv over WiFi.
Raspberry pi’s are really cheap. The hardest part would be how to get them connected to WiFi & Bluetooth devices for non-technical people.
I was going to suggest they publish the specs and let the OSS community create the mechanism, but that would invite cheating.
