Is there a way to tell actual sleep time and not just usage time?
I tend to wake up in the night, even with the resmed 10 on, use the bathroom, and go back to bed. Sometimes I just wake and then try to sleep again. It often takes a long time to fall back asleep. But the sleep report reading is just mask wraring time and not being asleep time.
Is there a way to measure actual being asleep time?

There sure is, just download OSCAR software, get your CPAP data imported and you can pretty clearly see via the Tidal Volume and Respiration Rate charts when you are asleep and awake.

Yes, but not foolproof. Wake breathing is much more erratic that sleep breathing. Sometimes that's easy to spot on the
OSCAR graphs.
Although the sleep report will show all time while wearing the mask when the machine is on, whether asleep or awake.

Smart watch...

Not too reliable I read. If so, wouldn't need PSGs in sleep labs lol

A smart watch is better than nothing. My old Apple Watch 6 has been great to track sleep improvement since I started therapy four months ago. I had sleep issues last night and the Watch did a great job identifying the unusual amount of wake time. The time periods it says I was awake correlate nicely with the erratic respiration shown in my OSCAR charts, as described by other previously.
An added bonus is the oximeter in the Watch has always been spot on with hospital equipment. I’ve had numerous cardio-versions and use every visit to compare my readings against their equipment (SPO2 and EKG).
Readings from that Watch have been sufficient for my PCP to refer me for my first sleep study. It’s SPO2 readings tracked with the low readings identified during both the diagnostic sleep study and titration study a few months later. My cardiologists have scheduled numerous cardio-versions based on EKGs from that watch. I send them the pdf file of the scan through the patient portal.

That is amazing your doctors use the info from a watch. Every one I've ever spoken to blow watch findings off immediately and literally laugh at me. In fact, my recent sleep doctor made a comment on that issue. I'm glad it is of benefit to you. A spot reading on SPO2 with a watch is drastically different than continuous overnight monitoring. I think where a lot of devices fail based on reading is picking up fast changes in SPO2 and having good accuracy below 90% levels. I am sure a watch can detect 'wake' time and OSCAR shows obvious changes in breathing and pulse rates when up, but I have my doubts on accuracy of REM and other stages. If it provides enough info to start a dialogue, that's great. So far my CheckmeMax O2 wrist device has not caught any physician's attention regardless of what it states.

From my experience, OSCAR will show your breaks in therapy - ie when you took your mask off. Seeing those breaks, you can follow th patter after the break.

It wasn’t always that way. I had to demonstrate a pretty good understanding of what was going on, medically, and that I knew how much weight to give the data my watch was generating. I’m a skeptic by nature and it probably helped that the PCP has known my family since he finished his residency (25 years) and knows that I’m a retired instrumentation engineer.
Maybe it’s an Iowa thing, but I’ve never had a single medical professional criticize the utility of an iWatch. Their biggest concern is people reading too much into Watch data and flooding the ER needlessly. I don’t think it’s a coincidence that most all of the nurses and my cardiologist have iWatches. The electrophysiologist has a Rolex and shiny shoes.
It’s just a tool and a exercise coach that I can use to help manage my CHF, Afib and now OSA. It’s more than an “Idiot light” but certainly not a calibrated gauge. When I can afford one, I want to get an oximeter that can monitor SPO2 continuously and work with OSCAR. Until then, I’m pretty comfortable with my Watch telling me PAP therapy is working. I certainly am sleeping better and have more energy.
This has been my personal experience.
