Here are the tricks I have figured out so far, all thanks to postings on the forums.
AIRPLANE MODE SEEMS TO BE THE SECRET SAUCE HERE.
- Click the Menu button on the ATV controller to turn on the ATV
- Put phone into Airplane Mode
- Start Zwift Companion on phone and make sure it is visible.
- On ATV click on user which should take you to Paired Devices
- If just the two orange boxes, click on the Power Source box and select KICKR SNAP
- Ride slowly to activate Snap and cadence sensor.
- If Heart Rate and Cadence boxes both are blue and show data, you are done.
- Otherwise, click on the box that is orange or not showing data and select the sensor
When you are done, remember to take phone out of Airplane Mode!
If having problems, click on “Use Apple TV Bluetooth Instead” in the top left corner. When you try to connect the second sensor (plus trainer) this will lead to getting the Bluetooth Error “Apple TV is out of Bluetooth connections. Would you like to try to connect through Zwift Companion on your smart phone?” Click Yes.
I have made sure that my Apple TV and phone are using the same WiFi network. Not sure if this is needed or not.
