Seriously though, in the end I did watch it with hibernation disabled, and sure enough the "smart" power plug turned itself off and on again at 08:00.
I've checked and rechecked the settings on the thing, and it positively, definitely, absolutely does *not* have a scheduled power cycle at that time. In fact I'd completely disabled it during the experiment (but of course left it connected), yet it still decided to do this entirely of its own volition.
In other words, it's a bug in the plug.
I have a few of those things, thankfully none of mine have done that (using a widespread Tuya chipset). I won't use them for anything critical, or risky. Just a few light bulbs and a pedestal fan. I'd never trust them on something that might be a fire risk (heaters), or requires stability (computing equipment).
I wish I could hack them to be controlled by Linux in my LAN, rather than some server on the internet which might decide they're wasting too much money supporting hardware you bought a few years back. Since I do have a PC on 24/7 it's certainly feasible in my situation. And other people have things like Raspberry Pies that they're happy to leave one running all the time.
