Otherwise it sounds like the factor is you
Honestly tried everything, logically working through what it might be, so I think it must just be that my body is the wrong design for any HRM
As a side note, one time I had an ECG due to the arrhythmia, the paramedic said he'd never seen anything like it on the printout. Like someone had dropped a pen in an earthquake. So it's probably that.
3 HR straps connected to two different output devices using two different protocols all do the same thing?
Have you tried taking all three straps outside, pairing one while sitting and then standing up and running on the spot, remove paring, repeat with the others, just to see if they do respond away from your computer, house, etc? Otherwise it sounds like the factor is you.
Are you wearing the straps so the sensor pads are on your chest and the buckle is at your back or side? People laugh when others put helmets on backwards but could you be putting all three straps on the wrong way?
