Wahoo Fitness to record treadmill session equipped with NPE Runn treadmill sensor

I am using an NPE Runn treadmill sensor to sense and transmit treadmill speed/ pace data.

Wahoo Fitness gives you the option to have a treadmill profile and record a session, but I’m having trouble getting it to display and record speed/ pace data, even though it says it is connected to the Runn device.

My Zwift app has no trouble connecting, displaying, or recording, so I know the unit is functional.

Anyone have any thoughts on how to configure Wahoo Fitness to register the Runn sensor data?

Thanks -
