Vivoactive 4 as Heart rate source for Zwift

Hey guys, I got my Vivoactive 4 and wanted to use it to track and display my heart rate in Zwift. Unfortunately, I absolutely cannot connect the Vivoactive 4 to Zwift to display my heart rate. Do you have any ideas how I can do that?

thanks in advance.

It should be flagged that to connect Garmin HR with Zwift you may need to use the bridging connection option offerd by the Zwift Companion app.

I wasted a lot of time viewing YT videos and forum posts that are misleading, and thinking there was a bug or synching issue eg bluetooth.

So buried over at Zwift has a specific tutorial buried in its help pages (that my Garmin Vivoactive 4 needed) on how to connect them using the Zwift Companion app support.zwift.com/.../pairing-a-heart-rate-monitor-to-the-zwift-hub-BJdmU8so

This is because Vivoactive 4 broadcasts the HR only over ANT+

I hope this helps others out there.

I was able to easily install a CABLE Util Ant+ device to sit in between a CycleOps 300 trainer and Zwift. The CABLE device receives power/cadence from the CycleOps and HR from watch, then transmits both to Zwift
