Garmin Fenix Broadcast -> Garmin Connect HR Black Hole

Hello Zwifters!

Super-excited to have built my Pain Cave and ridden my first short ride last night.

I’m using:

  • Tacx Vortex Smart Trainer
  • MacBook Pro with ANT+ Dongle
  • Garmin Fenix 3HR broadcasting HR via ANT+
  • Garmin Cadence Sensor
  • IOS Zwift Companion App

All of my sensors were connected and working as expected during my ride. When completed, I saves it to Garmin Connect.

When I look at my Garmin Connect Daily Summary, the time during which I was riding shows no HR data - just blackness. It DOES show an Activity though, and when I open the Activity, it dispalys all of the data that Zwift recorded, including HR.

Digging a bit deeper, it appears that my HR during my Zwift ride did not contribute to my Garmin Connect Intensity Minutes.

Has anyone experienced similar?

Thank you - Ride on.

There are several Garmin metrics that are calculated on the Garmin watch or head unit and synced to Garmin Connect. In my experience, these do not flow through Zwift… they’re proprietary to the Garmin ecosystem.
