Vivoactive 4 as Heart rate source for Zwift

Go to settings on watch, and broadcast the HR. Zwift will see it. It works.

Hi guys, having the same problem here. I'm broadcasting the HR. But Zwift doesn't see hit. Any other suggestions?

Any resolution for this issue? Same here!

Did 4411990's post not work for you?

Nope. Same issue reported by C.Rila.

Vivoactive 4 broadcasts the HR only over ANT+, it does not have the option to broadcast over Bluetooth like other, more recent Garmin watches have. It means the device that runs Zwift has to have an ANT+ receiver. If you run Zwift on a computer, there are ANT+ USB sticks, but check first at Zwift whether it supports ANT+ receivers at all.

Yes, I use my phone to run the Zwift app, and it has ANT+ drivers, etc.so nothing special needed.

The problem is that there is only a handful of phones having ANT+ hardware, so that will not work for everyone.

ANT+ enabled phones are listed for example here: ANT+ in Phones and Tablets - THIS IS ANT, but it is safer to check the specs of the device used for Zwift.

Thank you sir!

As others have mentioned, VA4 can only broadcast on ANT+. If your Zwift can receive ANT+ (e.g. running on a PC with ANT+ receiver) you still need to activate broadcast on the watch. But you don't want always-on broadcast because of the battery life impact.

I found that the most comfortable way to enable/disable on demand is setting broadcast to "only during workout" and starting one of the indoor profiles whenever i want broadcast to happen (indoor, because i don't want to waste battery on GPS, usually i just discard that workout afterwards).
