I have 2 smartwatches, Forerunner 265 and a Vivosmart 5. I use the FR 265 every day when I work and do sports, especially running. Meanwhile, I use the Vivosmart 5 when I'm at home, cycling and sleeping. What I want to ask is, when I use the Vivosmart, then I use the FR 265, can the data from the time I use the Vivosmart be used to calculate my HRV when I use the FR 265?
