It integrates with nest to control the thermostat.

Beyond that ... get a lighter weight blanket?

I have trouble sleeping if my blanket isn't heavy enough -- it's not a warmth issue, as far as I can tell, but rather a weight one. That, and having a warm body but breathing cold air seems to be something I like. That might be what the parent was talking about, rather than feeling too-hot in the blankets.

Same.

It's a real challenge if you live somewhere warm. Even using only a sheet and with a fan blowing directly on me I still want/need colder. Here in NC it'll often be 85-90F and humid, even at night.

This is obviously not a nightly solution - but a family member of mine moved from our northern US state to Africa for a time and swore by the following strategy to stay cool: utilize evaporative cooling by wetting/wringing out a lightweight sheet and use a fan to blow air over your bed.

In Spain even just sheets are too much :) Airco or sweat.

if you could figure out a way to get microfibers to straighten out / curl up on command (like under a DC electric field), you could make a smart blanket. it would regulate the loft of the material by making the fibers straighter or more curled, making it more or less insulating. i dont know if this is a stupid idea or not.
