Heart Rate Variability unable to detect

[Bauer24]

Hi. On the Sense, every time I do an EDA scan, on the ‘Heart Rate Variability’ section it always says “unable to detect”. Anyone know for the reason for this? I get readings for everything else. And stay extremely still when I do the scan. The watch is under three days old.

Try restarting your watch first, to see if it clears the problem.

Shut down the watch

[Swipe left, Settings, at the bottom, Shutdown]

wait a minute

Start the watch

[Hold button till it vibrates or logo appears]

Wait for the clock to reappear.

[Bauer24]

Nope. No difference.

As a matter of interest it says "unable to detect" what? Perhaps there is more to this message if you keep scrolling?

Does it show at least your starting - ending heart rate?

[Bauer24]

 

Yes. It shows everything else. Like start and end heart rate. But just doesn’t show heart rate variability, says make sure you are touching the case.

@Bauer24 Thanks.

You probably aren't still enough for it to register.

[Bauer24]

Trust me. I sat very still in all 20 of the times I done it. I managed to get a reading once! Not sure what the difference was from the other 19 times.

@Bauer24  It might be your watch is super sensitive [there must be some variance between them] so you can have lots of fun practicing!

Or replace it is another possibility.

I get the exact same issue.

I have the same issue. I've tried different times of the day, laying down, sitting up, you name it.

@Bauer24  @Soozeei  @ash8410  May be a silly question, are you a premium user?

You can easily check,. You are if you have a yellow ring around your profile photo in the app, or health metrics tile which gives you a graph of heart rate variability.

In the phone Fitbit App

I have the exact same issue and would be keen to hear from anyone who's managed to get HRV readings during their EDA scan as I have never got one. I also stay very still throughout the 2 minute scan.

[Soozeei]

Yes I am a premium user.

@Soozeei  Well it should give you a reading. Do you place the palm of your hand on the face of the watch so that the screen is presses in the palm and the rest of the hand touches the watch all round the sides?

[ash8410]

Yes, a premium user!

[Guy_]

@ash8410  Thanks, then try the method described in my previous post.

Am interested if there is a technique which does not work, or if its a watch fault.

@Bauer24 - Another tip in the Fitbit Help pages is to tighten your band (it should be tight but not constricting). You can read more about it by tapping here, then scrolling down to Why Didn’t The EDA Scan Work.

Same thing for me. It's not worked since day one. Always says unable to detect. No matter how still you are.

premium user here, I am having the exact same issue, my sense is about a month old.
