Sleep tracking bug ?
-
@Mauerwegler When I set my resting HR in the watch to my nightly resting HR, sleep tracking does NOT work for me, neither do resources (they don’t rise then) - As far as I think it works it’s, that the watch „knows“ when you fall asleep by the fact, that you don’t move anymore and your HR goes down (and perhaps some other factors I don’t know). The difference between sitting on the couch ( and not moving ) and real sleeping is, that there is a difference between your average daily awake HR at rest and your nightly resting HR. And for me it works
Short comparison table: Suunto Race, Oura and a Whoop Strap (last 3days). I don’t care too much about sleep stages (though they seem roughly the same) but the sleep and awake times seem to fit.
Race seems to be a bit on the „late“ side, but that’s ok and MUCH better, than with other watches, especially Garmin, who was almost completely wrong for me.

@ChrisA That’s a pretty clever trick, thanks a lot!

@Egika Shouldn‘t the watch be capable of finding the resting HR by itself?
possibly yes. Just as zhang965 has pointed out, it currently does not. You could do it yourself easily when sitting in a boring meeting by pulling up the HR widget.
What you read there sitting calmly not doing any thinking is your resting HR.For an automatic detection you’d need to tell the watch that you were ‘now’ resting. The effort compared to the above is probably similar…

I updated the original post including the most important insights of the discussion.
Thanks a lot for all the answers! -
@ChrisA
Thanks, I‘ve seen your posts where you explain your „rest HR“ trick to get sleep tracking working. I first thought you are doing it wrong but now I think SA is wrongly presenting the min. HR so prominently in a dashboard widget and thus putting some users on the wrong track! Also @Egika explained how to determine rest HR in a meeting above. That is what I thought was rest HR, too.I think the SA is in general really good with the analysis it offers, but the rest HR only might indicate something about overall current health (higher min. HR could mean recovering from training or getting ill), nothing else. I need to study the articles on suunto.com (just read https://www.suunto.com/de-de/sports/News-Articles-container-page/Figure-out-your-training-zones-and-supercharge-your-fitness/).

Thanks, I‘ve seen your posts where you explain your „rest HR“ trick to get sleep tracking working.Actually I learned it here in the forum - don’t know exactly from who, I think it was @Brad_Olwin but I am maybe wrong, I learned so much here
. But I agree with you on the terminology of resting HR and I don’t know for sure, if what I am doing is the right thing, it works for me, so I do it this way. -
@ChrisA @freeheeler is to blame for his trick
in all seriousness, resting hr is not same as avg min hr during the day not the night looks like there is some confusion on Suunto side as well, the online manual suggest to use min hr as resting hr which isn’t accurate for general purposes, however seems to be working for some folks in the Suunto ecosystem

@herlas thanks and Kudos to @freeheeler

@ChrisA you might have, we have gone over this in the past to get HR working, now it makes a bigger difference for the sleep tracking.

Sorry to beat a dead horse (or maybe it just has a low resting HR?), but Suunto suggests to "Use the lowest heart rate reading measured during your sleep as your Rest HR” in the Race User Guide under Widgets » Resources. The same is stated for other watches as well.
So is the Sleep HR + 10 trick just a hack for those having trouble with sleep tracking? Or is the user guide incorrect and out-dated?
I known there is some discrepancy as to the “correct” definition of resting HR, but it seems Suunto has chosen the lowest sleeping value. However, I have a feeling that what Suunto labels as “Minimum HR” under Sleep is perhaps a minimum average over a 10 minute period. Having worn other devices while sleeping, I know that my absolute minimum HR often dips well below what Suunto labels as minimum. Is this perhaps a holdover from the times before 24x7 constant HR tracking? If so, this would actually be a pretty decent measure for a resting HR and similar to how other companies calculate it.
Sorry if these particulars have been discussed previously. I tried to go back through a few topics on the subject, but there are a lot!

@duffman19 thank you for bringing this up again.
I guess that common sense in this forum is, that resting HR really is resting HR, and that this Suunto paper is just wrong… -
@Egika so what to do now!?

in regards to what?
I think what is meant is: will Suunto tell us what is the right thing and update the documentation?
-
@Mauerwegler don’t know. I am not Suunto…

I know. But could you make them aware of our confusion? Janne who wrote https://www.suunto.com/de-de/sports/News-Articles-container-page/Figure-out-your-training-zones-and-supercharge-your-fitness/ probably can advice.

@Mauerwegler actually I have done so in January already…
There is this older read about resting HR here: https://www.suunto.com/de-de/sports/News-Articles-container-page/know-your-resting-and-max-heart-rates/?category=SuuntoTri
It advises to measure HR right after waking up - but maybe is a little outdated…
And again - I repeat myself: the forum has come to the conclusion that resting HR is actually resting HR as it says. Everything works well with this setup.

I had a great sleep last night, out cold by ten, woke up at 6.40. Suunto claimed I’d slept for 2.38
-
@David-l I have the same problem every night. Sleeping hours in SA have gone down by 2 to 3 hours each night, since I have the Race. This is definitely wrong. There might be room for some optimisations
-
@wmichi sleep tracking is spot on for me. Very impressed!
