Do opticals now do HRV? Can't find anything definitive saying they do which makes me think they don't.

They send a number but it probably isn’t that accurate - there’s a lot more filtering to get a heart rate out of OHR than ECG and nothing as easy to latch on to for precise timing as the R wave (if I remember my waves correctly).

I think they don't, I presume this is because they don't work electrically so timing the interval between successive R nodes isn't possible.

Interesting because the HRV apps I have tried with optical have worked intermittently with my 645 but currently with my 245 do not read anything.

Is that looking at HR broadcast from the watch to your phone, TS? ANT+ transmission will always have an HRV value because it’s part of the standard, but it may be values that the app is struggling to make sense of.

245 doesn't show HRV on Runalyze on runs from what I can see.
