Activity Recorded with Tacx Training App Partially Syncs to Garmin Connect

I’m encountering an issue where activities recorded using the Tacx Training App (iOS) only partially sync to Garmin Connect. While the activity appears in Garmin Connect, with heart rate and power charts visible within the activity details, the heart rate data does not show up in my timeline (calendar). Additionally, metrics like intensity minutes, training load, and training status are not updated.

When I record activities using my Tacx Neo 2T trainer via the Edge 840 Solar, all metrics sync perfectly, and no data is missing.

Details:

Devices and Software:

Garmin Connect App: Version 5.8

Tacx Training App: Version 5.63.7

Trainer: Tacx Neo 2T

Bike Computer: Edge 840 Solar

Heart Rate Monitor: HRM Dual

Heart Rate Monitoring:

The HRM Dual is properly connected, and heart rate data appears in the activity details in Garmin Connect. However, it does not populate in the calendar or update related metrics such as intensity minutes, training load, or training status.

Recording Process:

I record the activity directly in the Tacx Training App, without using the Edge 840 Solar. The activity is started and stopped in the Tacx app.

Synchronization:

The Tacx Training App is set to auto-sync with Garmin Connect. The activity appears in Garmin Connect with power and heart rate charts, but related metrics remain missing.

Firmware and Updates:

All devices and apps are updated to the latest versions.

Additional Context:

This issue has persisted since I started using the Tacx Training App; it has never worked as expected.

I have not taken troubleshooting steps yet as I’m unsure where to begin.

Question:

Why is the activity recorded in the Tacx Training App only partially syncing to Garmin Connect? How can I ensure that heart rate data is fully integrated into the timeline and that metrics like intensity minutes, training load, and training status are updated?

Thank you for your help!

    Yes, that is how it works…

    Yes, that is how it works when you do not wear your Primary Wearable Device (the watch). Only if you had a strap like the HRM-Pro or HRM-Fit and it were linked directly to Garmin Connect, you would get some of the data.

  • Thanks for your response.

    What I don‘t get is that it works when recorded via the Edge. There I‘m not wearing my watch either.

    So with the same HRM, the same Tacx Neo, I get a different experience based on the device I use to record the same thing? This doesn‘t sound so much like a feature but like a bug.

    What would be the point of using the Tacx app then anyway?

    Probably not all, though. Edge for example does not support Body Battery. And I am also not sure you get the HR into the all-day graph. Previously it was not the case, but it is possible it changed recently.

    TBH, nothing, except of the virtual tracks and movies, if you need those. Otherwise, the best is recording the indoor rides with your PWD, or as the second best choice with the Edge.

    This works since at least last October (that‘s when I started to use this setup).

    I’ll continue with the Edge setup as I don‘t want to wear my watch (I need to charge it somewhen)

    thx anyway for your help!

    You do not need to wear it, as long as you connect the HRM strap (and all other sensors) to it, and start the activity. You just keep it somewhere in the proximity.
