Suunto has nailed sleep

[gone troppo]

I haven’t been on this forum for a good while, somewhere between when I was last on here and now suunto have done something to nail sleep. My suunto vertical used to get sleep totally wrong about 50% of the time and nail it 50%. Well whatever they have now done it is now nailing it 99.9% of time. Sleep and resources are spot on. Bravo suunto for whatever you did.

@gone-troppo Glad to hear as mine are good too.

The only thing i dont like sometimes is when i wake up for toilet or something, it stops, and dont continue sleeping, just shows sleeps result. But sometimes it works totaly perfect.

@Tami999 Same for me - like last night. I woke up, but went back to sleep. My 9PP stayed awake

[babychai]

@Tami999 i remember mine will continue count sleep again even after show sleep report as long as i woke up a while during my sleep tracking range.

[thailon]

@wakarimasen the same for me

[isazi]

@babychai I believe that for the Vertical and S9PP (the watches that do not track naps) if you go back to sleep and you are inside your usual sleep time, it will keep counting sleep. If you are outside sleep time, I don’t think it works.

I can confirm on my SVTi that if I wake in the middle of the night I sometimes get the sleep summary screen, but if I then go back to sleep, the watch keeps tracking sleep and gives me the complete summary total at my normal ‘end of sleep’ time.

Just completed the 14-day calibration for HRV and I too find that sleep tracking and HRV works very good.

It’s a short period of time for a complete assessment, but it seems that HR sensor works very good for me.

The first time I saw random high HR it was because the strap had to be one spot more tight. It was evident that green light from the sensor was “bleeding”. Maybe the band elongates a bit on initial use.

A good test is to hold your hand in multiple positions and orientations and check if green light “bleeds”. Now only when my sleeve gets under the watch and raises it a bit wrong values get monitored.

@Swaddy61 I have also the same perfect behavior.
Since last update sleep tracking is perfectly spot on 99% of the time.

Two more things I noticed:

1. Although Vertical does not track naps, on “Resources” bar-graph it seems that if I take a nap, the corresponding bar do gets lighter coloured

2. Also when blood oxygen tracking is enabled, the watch measures the oxygen levels when it “understands” that you are kind of “inactive”, but the measurement is not so good. So on the sleep report I get something like 99%-100%, but because when I wake up I still get sometime on the bed, the watch re-measures the oxygen but I am a bit active/moving, so the last oxygen levels measurement appears to be on a lower level.

@isazi Should i set my Vertical for sleep time between 0:00 to 23:55 (aka 11:55 PM) than? to make it record-time almost 24/7? It should take and count all naps and toilet-drink time in night.

Then you will get naps with your vertical too, in addition to your sleep data from the last night.

@pilleus
In addition or replacing night sleep?
Do you see both your night sleep duration and a nap registered?

[pilleus]

@Mff73

In addition. As sleep recorded twice.

[pilleus]

There is one more thing to note: the widget in the app only shows the sleep at night (9:12 h), when you open it the short sleep is listed separately (0:27 h).

In the vertical, the entire time (9:39 h) is displayed as sleep for today in the sleep widget.

[pilleus]

Ressources will rise a little bit during the short nap.

[pilleus]

Another successful test with a power nap

[jakubdr]

I can confirm. Previously, my Vertical never registered sleep correctly. Now for the past couple of nights it feels like magic. It registers the start of the sleep almost to the minute. I have not changed anything, so I guess Suunto tweaked the algorithm. Big kudos Suunto for nailing this!

[Wilson75]

@jakubdr I have the opposite feedback about my sleep tracking. My sleep tracking is not accurate I fell asleep at 11 pm and woke up at 7:30 am I got 4:30 of sleep…
