Has anyone here used the S+ with their CPAP machine ?

Curious if there's $80 of benefit in a person whose AHI = 0.1 and is sleeping well and feeling fine. Was told that this device can determine REM vs. sub-REM sleep.

My question about all these little gadgets to tell us our sleep stages or if we slept...assuming they are spot on accurate which I really have some serious doubts how something on my night table can really tell how I am sleeping or even if I am sleeping...is what are we going to do with the data anyway? What is it going to change in what I might be doing that would improve anything?

And no....of all the things I might waste $80 on....that little gadget wouldn't be on the list even if it was "accurate" and I have some serious doubts as to its accuracy anyway.

No I have not tried it, and like our friend "Pugsy" I am quite skeptical of its value or usefulness.

I think it is curious and interesting that ResMed bought the assets of Zeo and then launched their own very similar device, but instead of monitoring brainwaves as Zeo does, the S+ uses motion detector technology. Zeo works fairly well, IMO, at determining sleep stage, but does have some difficulty distinguishing REM from Wake, not unlike many sleep professionals. Zeo's results might not be spot on accurate, but they are repeatable and therefore useful in establishing trends. I find it hard to believe the S+ technology could come close to matching that of Zeo.

I thought perhaps ResMed would eventually use the Zeo technology in their own device(s) and maybe they will, but they don't seem to be in a big hurry. Maybe they just wanted to ensure that no one else was able to use it.

As far as usefulness, I found Zeo helpful as an objective measure and confirmation of my subjective feelings of efficacy when I was trialing meds to treat PLMD and fragmented sleep in my earlier CPAP days (I didn't find any that were effective, BTW). For that, I relied primarily on Zeo data to establish the trend in the amount of deep sleep I was obtaining along with trends in total sleep and wakes. I continued to use Zeo as I explored the principles of Sleep Hygiene to improve my sleep, again relying on its objective measure rather than my totally subjective feelings. Now that I seem to have done pretty well at optimizing my sleep, I don't use Zeo much any more. Once in a while I will wear it, just out of curiosity, but its reports are boringly similar. So now, it has become kind of a geeky toy rather than a useful tool, but I wouldn't part with it.

I have a Zeo, which is much more accurate;
And a Misfit Flash, which would give me similar data if I wore it at night.
I used the Zeo for a few months, and wore the Flash at night for a month or so.
My sleep stages (with cpap) are so normal now, it is boring as heck.
