I have the HRM PRO PLUS connected to the garmin epix 2 watch and to garmin connect.
i tried it with treadmill activity on my garmin epix 2 watch , while wearing the HRV PRO PLUS and it works , giving all the data.
I tried it with stair stepper activity on my garmin watch , while wearing the HRV PRO PLUS , and it didn't provide any data .
I suggest a software update to add support for the HRM for stair stepper activity
