Yeah, thanks.
I’ve done some more research and i’ve read about ANT+ dongle in the USB (of course i’d need to use zwift on my laptop). Do you maybe have experience with it?
If you are using a Laptop I would suggest an ANT+ dongle with a USB extension so you can get the dongle as close to the trainer as possible.
Thanks a lot

Hi Paul. The Garmin HRM has always worked. It now doesn’t. There’s a different problem with Zwift not enabling HRM to function as it used to. It would be nice if someone got to the bottom of this urgently and sorted it out fir us. It’s particularly frustrating training with no HRM

I run Zwift on Windows 7 and in the last week my previously faultless connection with Garmin HRM 1G has evaporated. Can’t even search / discover the HRM. Appears to have occurred following last update. Please could you look into this Zwift. I can still connect HRM to Garmin watch so proven functionality. I have ensured all other devices are shut down so does appear to be a Zwift error.
Same issue here. Garming Duel HR just stopped working. I tried everything, even did a factory reset on my phone. Tried calling Garming Customer support- Couldnt get through. Solution for me: I returned the Garmin HR Monitor and purchased a Wahoo Tickr
Same here, dual hr works fine on all other devices, both BT and ant+. This is an issue with zwift

I was having the same problem as others here - Garmin dual HRM wouldn’t stay connected in Zwift. I apparently have the good fortune (?) of owning too many computers. In my case, switching computers solved the problem for me, leading me to believe that this is a problem with computer chipsets and how bluetooth signals are handled by the software. The computer that doesn’t work runs an Intel Celeron J4125 (designed for mobile devices) and the one that does work is running an older (Gen 6 I believe) Intel Pentium i7-6700. The two computers will also have different supporting chipsets, which may be the cause of the problem. This may also make finding the solution more problematic. Happy to help Zwift staff with more details if desired.
I have the same issue with a Garmin Dual HRM connecting to a Macbook Pro.
It connected via bluetooth without issue once, working faultlessly.
But now cannot be found upon searching in “Ride” bluetooth page.
However, it can be found in the “Run” bluetooth page with no issue, during the same Zwift session! 
Same problem here. My garmin dual HRM was working perfectly fine a but since approximately 2 weeks it does no connect anymore to zwift. However it is working perfectly with other apps or device. I tried evrything but without success… It seems to be a Zwift issue.
Hi,
Yes same here, Worked flawlessly for months now not recognised, or able to give me a bpm reading? tried changing battery, conecting unpairing pairing… phone see’s it instantly? Watch connects?, Must be an Zwift issue…?
It see’s it on the pairing screen , but doesnt connect…? very frustrating especially when trying to perform a coached session…[quote=“Josh_Cranage, post:1, topic:469287, full:true”]
I have been trying to connect my Garmin HR monitor to Zwift but it has not been showing up. I know it works because it always connects to my Garmin. do you have any tips to help make it work?
Same issue, running on an Apple TV box, HRM worked well for months, now no HRM read out. Was using a Scosche arm band and now have a Garmin dual chest belt, neither work. Please acknowledge the issue Zwift.
Please read:
Has anyone had a reply from garmin or zwift yet what the issue is
I have a garmin heart rate monitor and it connects to everything I have but not zwift?
Zwift really need to do some work here. I am here (on this forum) because I have been frustrated for the past 2 weeks connecting my Wahoo Tickr Fit which has worked about 5% of the time, and never for a complete ride, which I bought by the way because connecting by Apple Watch for the HRM functions I could not get to work reliably either. I found this forum in the hope that a Garmin HRM would give me some reliable connection, but alias it seems to be a Zwift issue (and iOS) that they need to address and take ownership of.
I have the same issue. I have only been using zwift for about 2 weeks and all of a sudden my Garmin HRM dual will not read my HR on my laptop running Zwift. Sometimes it won’t even pair and other times it will pair but either say “no signal” or read “0” for my HR. The HRM does connect to my garmin edge 820 without any issues.
It would be nice if Zwift took this issue seriously and came up with a solution, especially since it seems to have been an issue for several months now.

Same issue, fixed with the purchase of a Garmin ANT+ USB.
I have the Tacx Neo 2T, Zwift, Windows 10. Worked for a week and then HR quit on me. Picked up my Garmin strap, but ‘No Signal’ issue. Complicating matters, I also have wireless Bluetooth Bose head phones that I use to listen to music on my iphone while I ride, as well as having the Zwift companion app open.
The Garmin ANT+ USB cured the HR problem. Yes, it’s another $50, but given I spent $2k on the trainer…

Same problem, Zwift saying HRM connected but no display… worked fine for a week then boom… appears a very common problem with no solution…
Looks like bye bye Zwift
About 50% of the times Zwift doesn’t detect my Garmin HRM. Outdoors I use the HRM together with my Garmin 520 so when Zwift doesn’t detect it I turn my Garmin 520 on (and off again). Within a couple of seconds after the Garmin 520 has been turned on Zwift detects the HRM
