Can't start running on Kettler S10 treadmill with Zwift on AppleTV

Hi,

I do not get my treadmill Kettler S10 working together with Zwift on AppleTV:
The treadmill is shown in zwift on the appletv as a source for running speed (via Bluetooth) but the treadmill itself does not recognize its being connected to the appletv and therefore I cannot start the training on the treadmill.

I have tested the connection of the treadmill together with zwift on an iPhone and zwift on an windows laptop (all with direct Bluetooth connection) and it works fine.

I found out that connecting the treadmill via the zwift companion app on the iPhone as a Bluetooth bridge to the appletv works, but that solution is quite instable and just a bad workaround…

Best Regards,
Sebastian
