HRM connection issue. Garmin strap & Fenix 7

I’m running a Zwift Hub trainer through my laptop for Zwift. Never had an issue. Now my Garmin HRM-Dual strap & Fenix 7 watch are giving false readings (they worked up until about a month ago). I’ve cleaned the strap changed the battery, still no good. So I paired my watch same issue. It either gets stuck at it’s first reading say 80bpm…or reads really high 170-180bpm in Zone 2. Both the strap connected to my Edge 830 & Fenix 7 work fine outside, it is only when connecting to Zwift/trainer?? Is there a solution?

How are you trying to connect them to your laptop (ANT+ or BLE)? And have you, by chance, moved anything into your trainer area that might cause interference?

BLE. I’m thinking of getting an ANT+ dongle for the laptop, if it’ll solve the problem. Nothing has changed in or around my set up. I was wondering if it was a software update on my laptop or by Zwift?

Hi @stuart_francis_ENG,

Welcome to the forums! Jose here from Zwift.

I’m sorry to hear that you are facing issues with your HRM.

After reviewing your account, I noticed several BLE disconnection issues with your HRM. It seems that the HRM is already connected to a different device.

No need to worry, I will provide you with a few steps to resolve this matter so you can start your journey. Please follow the steps in this article.

On the other hand, I see that you are running the latest game version 1.82.0 which is great.

If you ever need help, remember that you can contact us at support@zwift.com.

Have a nice day!

Thank you
