I live someplace that often gets so cold it’s 65 F in the room when my thermostat is set to 80 F. The bed is fairly low to the ground, so I can imagine that some nights it might need to temporarily reach 115 F.
I share your pain...
I'm Canadian

I am not sure we should keep outsourcing natural bodily functions to tech, proven or unproven. A healthy human body has a myriad of interconnected processes designed to maintain homeostasis, and if you pull yourself away from the proverbial noise, you might actually be able to listen to what your body is telling you.
The more technological and pharmaceutical wonders we introduce, the greater potential for throwing things out of whack. The human body, properly cared for, is a finely tuned machine with millennia of R&D. I'm not saying tech like this won't be helpful for fringe cases, but we are fooling ourselves if we think we can best nature at her own game after only a few hundred years of modern science.
I would look at this as an attempt to get back to the natural rhythms.
Normally, one of the signals to fall asleep is cooling of the body slightly (this is why a warm shower is supposed to help you sleep - the body warms in the shower, then cools when you get out). This would have evolved to match the cooling of ambient air in the evening, concurrent with the increased melatonin release as the sun goes down (which, as you point out, has been thrown out of whack by the myriad of screens we face which emit similar wavelenghts of light).
A system like this could
theoretically help take the body back to the natural rhythm. It's along the lines of NightShift, f.lux, or whichever other system you prefer. Those attempt to minimize the light from the blue end of the spectrum, in order to restore the melatonin cycle that evolved over millenia.
I would also point out that for many people, falling asleep isn't a problem because we are chronically sleep deprived. There are numerous studies out there that document this clearly, and it is becoming increasingly evident that this sleep deprivation is causing many of the problems that we attribute to "modern living" (well, that and the fact that as a population, we hunt at McDonalds and forage at Costco...)
Apologies for the long message - this is a field that fascinates me, as I am becoming increasingly convinced that we are looking at the wrong things when it comes to preventing disease (or at least, we are missing some of the parts of the picture). And also because years of being on call has resulted in me having chronically poor sleep.
*** I used the term "evolved" because that is what science has demonstrated. Evolution is a theory only as much as gravity is a theory -- terminology in science does not always equate to colloquial use. If anyone is offended by my lack of consideration of alternative "theories", please DO NOT respond to me or this message unless you can provide mulitple peer-reviewed, reproducible, unbiased, and scientifically valid research papers documenting and supporting your statement. All else is BS and will be duly ignored. [Experience has forced me to include notices like this; this is not meant to sidetrack the topic at hand.]

I've dated a variety of shapes and they've all been freezing, all of the time, regardless of weather, time of day, or layers of clothes, lol.
My wife is at most a size 4, certainly not overweight or what the media defines as "curvy", and she is perpetually cold at night. We have a heated mattress topper that she turns on during the summer (her side only, thankfully), while I have to keep the A/C and ceiling fan going. I'm afraid of what's coming when she hits menopause.
From what I understand, women going through menopause will often shift from hot to cold and back again several times per night. I suspect that this has a significant impact on sleep quality. I wonder if this sort of system could sense those body temperature changes and respond in a timely enough manner that sleep quality could be improved?
(And maybe the women wouldn't be as moody? Just sayin' ...)
