Outside of Zwift, the heart rate monitor works perfectly.
The Wahoo Headwind responds to the heart rate monitor.
The heart rate monitor is found in Zwift, so there is a connection.
However, the screen shows “no signal”
This problem started in the last month.
Tried to connect to the heart rate monitor via “Direct Connect” and the App but this gives the same problems.
Occasionally it works, but most of the time it doesn’t. Very frustrating!
Which exact model of Garmin HR monitor is it?
Does its manual contain any information about pairing/connecting with multiple devices at once?
Are you trying to pair to Zwift using Bluetooth or ANT+?
From your description, my first reaction is that the HR monitor signal is already being picked up by another device that you have paired it to (the Headwind or the Direct Connect app). Since some (most?) devices are only able to transmit to one other device at the same time, it might be necessary to shut off the Direct Connect app and to not switch on the Headwind before making sure that the HR monitor is getting a signal to Zwift.
To isolate the issue, I’d suggest going through the various switch-on/start scenarios with your devices in order to find a reliable sequence through which you always get a good signal to Zwift.
I use a Garmin-Hrm Dual.
Pairing with multiple devices has never been a problem.
The first months that I used Zwift I already had the Garmin in combination with the Headwind and this gave no problems.
There was always a regastration of the heart rate.
I think this problem started after using Direct Connect.
However, after disconnecting the cables, so everything via bluetooth, the problem remains.
Sometimes I see a heartbeat, but when I go to a workout, the connection with the heart rate monitor disappears.
I recently had a problem with my Garmin HRM strap not working on Zwift or my Wahoo ELEMNT computer. In my case - I also have a Wahoo arm strap HRM and a Lazer helmet HRM. All of them were paired to both the computer and to Zwift.
What worked for me is forgetting all three HRM’s in my Wahoo computer, as well as in Zwift. Then I re-paired my Garmin HRM since that’s my main heart rate monitor.
In Windows / Mac, you can reset your known devices by deleting a file in your Documents folder called knowndevices.xml. Would you log in, pair to your things again, and see if that solves it for you?
Thanks for your comment,
I’ve already tried the tips you mention.
Looked up an old Garmin HRM and it works without any problems…
When I pair the HRM with my Garmin Fenix, I see a different ID than when I pair the HRM with Zwift!?
Does that seem to be the problem? And why is that so?
The question remains, why doesn’t it work in Zwift and does ik work with all other devices?
I have the same problem. HR strap is connected on zwift but does not show BPM
I change batteries
I check that HR strap is working on other devices. So it works
I use HR strap dual band (yellow) from Garmin.
It is happening the same with my polar strap.
Both straps worked very well before with zwift.
Any solutions? I believe it’s some kind of software update bug.
I have been using an Apple TV with Zwift app and a Garmin Dual HRM with Bluetooth for some time now and recently started experiencing this issue. I tried all the usual stuff with the last being running an update of the app on apple tv. That fixed the issue for me. Incidentally other Bluetooth capable devices recognized the HR strap and saw a heart rate, so I knew it wasn’t the Garmin device itself. Seems like some sort of intermittent bug with Zwift software.
I am having the same problem but with non of the above brands, probably an entry level BLE Bluetooth 4 HRM. Bluetooth can see it on my devices, not being picked up by Zarmin (using it with a Tacx Force Smart trainer, but not connected to it.
MY Garmin ant+ HR has always worked Perfectly with zwift on a windows 10 pc with a suunto ant+ stick and extension cable. Now All of a sudden it keeps dropping and says “No Signal”, I fidget a bit slap it around take it off and put in on again and it works for a bit again then drops.
So I bought a new Wahoo Tickr and tried that via ant+ and exactly the same issue.
(Both have brand new batteries in them)
My Whahoo Kickr and Garmin Cadence Sensor Never Drop at all using ant+.
Next I will try Bluetooth with the snap and the Tickr and see if there is any difference.
Test 1
Connected Wahoo Kickr Snap and Wahoo Tickr HRM Direct to PC using Bluetooth.
Connected Garmin Cadence Sensor Using ant+ Direct to PC.
Tickr HRM kept Dropping, everything else was fine.
Test2
Connected WahooKicker Snap and wahoo Tickr HRM to my phone with Bluetooth as a bridge to the PC.
Connected Garmin Cadence Sensor Using ant+ Direct to PC.
