No deep sleep?

My Epix Gen 2 is not recording any deep sleep. For example, last night I recorded over 8hrs of sleep, 4hr REM, 0 Deep. Since receiving the watch weeks ago, it initially recorded a couple nights of minimal (20-30 min) deep sleep, but now its mostly "0". It is recording accurate sleep/awake times. The watch has no issue recording other metrics, including Pulse Ox, HRV, etc. There are no gaps in HR recording.

I have worn Oura ring for years. The Oura is recording deep sleep every night, including 1hr 55min last night! My previous Fenix 5 watch would typically record over an hour of deep sleep.

Is this a sensor issue? Pretty disappointing to see such poor tracking considering all the sensors on board.

I get all the sleep phases normally

I almost never get any deep sleep from my Fenix, while my Apple Watch (with Autosleep app) gives me at least 1-1.5h each night. I guess it's an algorithm thing, so I stopped paying so much attention to it.

Just seems so random, I assume the Fenix uses a similar Garmin algorithm, and is able to detect at least some deep sleep, while this Epix just thinks I'm dreaming away...

The same result for me - no deep sleep.

The sleep tracking on the garmins is pretty bad in general. I hesitate to even say it's 'good enough.' I had a little $45 Huawei fitness tracker which was always spot on and detected naps. Though I will say the Epix does a bit better than my 745. But still, for a $1,000 watch I expected some improvement. Grr..

The only time I didn’t log deep sleep this week was the night I drank whiskey before bed.

Lol, I kid you not…had a bourbon get together last night, my watch recorded 2 hrs of deep sleep. Seems to have the inverse effect on me

I've always been of the opinions that tracking of sleep phases is more guesswork than anything else from any device. Comparing sleep phases from one device with another essentially comes down to which set of numbers is preferred.

I'm never too concerned with the phases Garmin reports, only that it detects my sleep and wake times; which it invariably does. I'm with Apple's approach where they essentially say that measuring sleep phases has little to no value as it is not really actionable.

BTW, I did get some deep sleep apparently last night:

Absolutely true. Garmin is far from being perfect also when it's about starting/ending time of the sleep but it's correct majority of times.

I had fitbit sense and it was recording a lot of small awake times that at the end of the night was like 1 hour awake with 8 hours of sleep but, while it can be definitely true, i don't remember those half minues/2 minutes or whatever they are so why should i care? Garmin is pretty good, in my case, to detect when i'm really awake and go to the bathroom for example. And i had few nights in which also the fitbit recorded that i was sleeping during tv watching.

And oura, a ring that is like 300/400 dollars, still has issues with REM detection, in my case, and that's something that also the guy that is testing devices and comparing with EEG confirms.

Garmin is far far far away from usefull sleep analycer even if Firstbeat is theyr company. Cant understand why they did not get that wo work.
