I’m interested in your terrifying view though.
I mean, don't misconstrue, I am exaggerating a bit and tend towards caution over utility in these matters - it's totally doable, of course :)
It's the overall intent that would worry me - as someone else said downthread, I'm not sure I see the necessity of having the two homes directly linked, and as we know, adding an unnecessary component to a system is necessarily increasing its threat surface. The involvement of a cloud service bothers me a bit - it'd be one thing to have three servers involved, all fully under your control, but what happens if your cloud provider has some kind of security disaster? How do you deal with an external adversary that then has access to both your and your parents' houses? Or worse, what happens when your parents decide to get experimental with HA and brick all your lights? (I kid - you do make it sound like your folks are switched on and technically sane, but in principle - shit can go wrong on their end).
Personally, I think I'd go very barebones and just host a single bit in a text file on a web server somewhere - your HA could flip it to 1 when there's power to buy, and your parents' HA can just poll that every 15 minutes and do whatever it needs to while the value stays at 1. No direct linkage, minimal threat surface, and any bad actor snooping around will only find out that some URL on some web server sometimes serves a '0' and sometimes serves a '1'.
Please don’t be too principled as long as the tools and community to back up those principles aren’t in place.
I very much agree with this, @sunaurus@lemm.ee - your stance above is, I think, exactly as a stated policy should be, but please do remember that plans and reality must meet somewhere along the way. If you overthink things or cleave too religiously to the rules you've set yourself, you risk taking too long to act, and it's exactly this delay between problem and reaction that bad actors exploit.
Don't cut off your nose to spite your face, basically. Lemm.ee is a great instance, and we'd all, I think, love to see it stay that way 🙂
I can only think they must not have paid the poor chap enough. Just look at what's become of them.
I'm assuming they aren't close enough to just run some cat6 between both houses and have a single instance govern them?
I'll be honest though, although your plan sounds cool as fuck, it also sounds like a really terrifying project from a security perspective.
I choose to believe that Campbell deliberately selected that title to give everyone who hears it a Corrs earworm.
I will literally never tire of recommending "A Classless Society" by [ahem cough mumble idk just google it]
Historical summary of British history in the 1990s - hugely interesting to me, having lived through it, to see a higher-level analysis of what was going on, not to mention finding out a bunch of stuff that I'd either forgotten or missed at the time by being too busy with Airfix kits or scrumping apples in the golden dusk or whatever it was we did for fun back then.
Tories practically exist to fellate the landed gentry - they'll come for yours too given half a chance.
