I'm the opposite, I need to stay on my left side otherwise I go downhill. I have UARS too.
I have built a device that has a gyroscope and is battery powered. This straps around your chest and will vibrate and wake you if you deviate from the preprogrammed angles.
If you're unable to work out how to sleep on your back consistently let me know, I may be able to help.

On an unrelated note, do you have LPR/Silent Acid Reflux? That can cause nasal issues and is commonly linked to UARS.

Your solution sounds amazing and I am definitely intrigued. I guess I’m hesitant to attempt any solution that wakes me up because my sleep is so horrendously fragmented already and that’s the main issue I’m trying to solve really - to wake myself up for other reasons would defeat the point. But I’m intrigued nonetheless!

I was wondering about LPR. I do have a history of acid reflux though in recent years I’ve not been aware of it - EXCEPT when I was trialling the full face mask, which seemed to trigger horrendous reflux, I assume because I was swallowing air. I could never tolerate PPIs but was on H2 blockers for a few years. Maybe I should look into that again.

I have noticed (and my ENT observed at my last appointment) that my left turbinate seems more reactive and irritable than my right one. I almost always wake up having settled on my left side. I have no idea if this is actually how it works, but it strikes me that if stomach acid is causing the irritation, there might be more spillover to that side simply due to gravity. Hmm.

The VAuto has arrived. I think I've got it set to approximately mimic my Airsense 10 settings - it is definitely a bit more complicated than CPAP (and I don't have ResMed phoning me every two weeks to 'help' this time).

I had the Airsense in fixed pressure mode set to 7.4, EPR of 3, which was just about tolerable until my nose blocked up after a few hours.

Right now, I have the VAuto in S mode with IPAP at 7.4 and EPAP at 4.0, which, if I'm understanding correctly, is equivalent to an EPR of 3.4. I am hopeful that being able to breathe out with even a little less effort might allow me to sleep longer even when I'm partially congested, and will work on whether the inspiratory pressure is correct later.

I am curious about whether the VAuto would be more tolerable than the Airsense in auto mode using a higher pressure support setting, but given that every single tiny pressure change on the Airsense seemed to result in me waking up, I'm not sure I can bring myself to go down that road just yet.

It's great the machine has arrived! Do take it out of S mode, though. For some reason, in S mode, flow limitation data aren't generated or displayed in Oscar.

In regular VAuto mode, simply set your minimum pressure at 4, your PS at 3.4, and your maximum pressure at 7.4.

Stay with those settings for at least a few nights. Then you can try inching up your PS and maximum pressure. It's very nice being able to do that in tiny increments of .2.

Oh, I didn’t think of doing that! It arrived in auto mode and I put it in S mode, thinking otherwise the IPAP might slide around and not stay consistently at 7.4.

But I guess if the difference between IPAP and EPAP is 3.4, then as long as IPAP maxes out at 7.4, EPAP can’t go above 4.0; and as long as EPAP is at minimum 4.0, IPAP can’t drop below 7.4. Is that right? I feel like I’m still trying to wrap my brain around the logic of how the different bits relate to each other.

I also had no idea the mode affected flow limitation recording. Thank you so much for the information!

Yes, you have the right picture. You tie its hands so it can do just the one thing you want it to.
