Sleep tracking

[Egika]

@Sascha-Domres sleep tracking should be independent of checking the time.
I have had day where actually after checking the sleep stats at 5am, the watch went on registering me continue to sleep until 6.

Some guessing here:
Could it be that you synced the watch to the app between 5:30 and 7:00? So the data got written into the app?

[Sascha Domres]

@Egika Thanks for the tip. That could be the case… my iPhone is also in the bedroom and wasn’t in airplane mode… but that would also mean that I initiated the synchronization by checking the time and going to the toilet…?!

@Sascha-Domres you may try to raise your resting HR setting a bit. I observed, that for me raising the HR value makes awake times be more precise (although from a certain point on, the fall asleep times change to the worse then)

[Sascha Domres]

@ChrisA thank you i keep it in mind…

[Egika]

I am just trying to get this “rest HR” to be confirmed from Suunto kind of officially.
Right now we are just suspecting that is has an influence on sleep tracking quality. Theoretically, it could well be HRV that does the sleep tracking trick (as you know earlier times Suunto T6 came out detecting your respiration rate calculated from HRV).
Anyway, currently waiting for confirmation and some insights from the devs…

@Egika Thanks for reaching out to Suunto. In the meantime I keep on speculating. I slept 13 nights with the Race, only in two nights my sleep wasn’t terrible fragmented (according to Oura). And also only in these two nights my HRV was within its normal range (according to Oura). And in those two nights the sleep tracking of the Race was spot on. In the other nights the Race reported way too much awake times. So HRV could play a role. Ok, this is not a very scientific test

Maybe Suunto could publish a blog entry about their new sleep tracking? I think that would be beneficial for everyone and would end the guesswork.

@Egika would be interesting! Thanks!

Confirmed officially from Suunto:
The Resting HR set in personal settings has no influence on Resource and Sleep tracking

We were hunting some Voodoo effect here 🤪

@Egika I actually tested this and for me both were not working correctly if I set the resting HR in the watch to my lowest nightly HR. I will try it tonight with the Race ( have not tested it with the Race actually )

And many thanks for asking

Is it valid only for SR or also for SV S9PP etc? I ask this because I have the same problem as @ChrisA on my S9PP

[wmichi]

@Egika If it’s not used for resources and sleep tracking, for what else could this value be used? Maybe Suunto Coach?

[ChrisA]

@Egika seems to be correct setting resting HR to the average min average HR (taken from the Suunto app) yields good results:

Suunto

Oura

And resources raised accordingly

[wmichi]

@Egika I also tested it like @ChrisA. The Race is full of surprises

I have tested min resting HR on Race and S9PP with the new firmware. Both are yielding nearly identical sleep times and nearly identical sleep metrics. I have over two weeks with both watches. The sleep is now accurate for me and I am quite happy about that. I think the new firmware will please you as both @Egika and I seem to be getting reproducible and accurate data.

I think we could have guessed this was the case as both the Vertical and Race user guides state that the watch "tracks your sleep based on accelerometer data.” Both guides also state that more data can be gathered by enabling Daily HR, implying that sleep can be tracked even without the OHR enabled.

This seems to track with my experience as changing my Rest HR setting hasn’t affected the quality of my sleep tracking. My Suunto only marks awake times if I physically get out of bed and walk around, which I rarely do. However, other devices (Apple Watch, Garmin), which presumably do use HR data, will mark when I briefly wake to change sleeping position since my HR will usually briefly spike while doing so.

However, I have a hard time believing the Rest HR does not affect the Resources readings as it explicitly stated in the user guide that "It is important that your Max HR and Rest HR are set to match your heart rate to ensure that you get the most accurate readings.” This makes sense as an accurate Rest HR would be necessary to determine whether you are stressed (low accelerometer data, high HR) or inactive/recovering (low accelerometer data, low HR). I don’t see how this could be accomplished without the Rest HR.

Although I guess this forum is in agreement that the user guides themselves are probably inaccurate at this point, so who knows!

@duffman19 I changed yesterday my resting hr in the watch from a fantasy value (to make resources work with the Vertical) to my real resting hr, which is 10 beats lower. To me it seems this did not affect resources at all on the Race. Although I also don’t unterstand, why resting hr doesn’t make a difference.

I hope Suunto publishes some background information about sleep tracking, hrv and all the new stuff in blog articles. That would also good for website traffic (SEO).

@wmichi second night with nightly resting HR settings on the watch, gave me wrong fall asleep time by an hour. Will see if that’s persists.

[DrSilverthorn]

Owner of a Vertical here. I tried increasing my resting heart rate up to 23 beats above my sleeping rate, and saw no improvement in sleep tracking. But I also wake multiple times per night, and move a lot even when sleeping.

While I remain hopeful for an improvement, I’ll not hold my breath. Will see what comes on Monday.

@DrSilverthorn have you tried a different strap? I had initial issues but swapped the elastic for a nylon Coros strap and it’s not only a lot more comfortable, but HR also seems to be better too.
