Garmin ANT+ dongle doesn't recognise hrm sensor

I have a laptop with W7, with the usb ant+ I’ve paired a wahoo kickr, wahoo cadance sensor and garmin hrm sensor belt to the zwift app,

in the file known_device on “document\zwift…” there are still the right sensors with serial etc defined

A few weeks ago it was all working fine, today the hrm was not found, could not find it with ant.

i checked new batteries, connection with garmin edge ok-> hrm show up.
all other equipment etc i have closed or shutdown, no garmin express running on laptop

Someoen any idea?

Hey there!

I’m sorry you’re having trouble pairing your HRM to Zwift using ANT+ signal.

I’d like you to submit a support ticket so we can help find a fix for the issue. In the meantime, it can help to make sure your version of Zwift is up to date. The current Windows version of Zwift is 1.0.37506.


Hi there I am experiencing the same issue with the HR. Did a someone come up with a solution
