> E.g. having your security system (my smart home implementation would include a data diode so the home automation cannot effect the house's security posture) notify the HVAC controller that no one's home so it can turn off the air conditioning
Or you could press a button on your way out of the house, and not have to have an array of finicky sensors and interacting components make these decisions for you. Like, seriously, a solution waiting for a problem
>and have the HVAC controller manage the motorized blinds / curtains / etc. so that whichever side of the house is currently facing the sun has the blinds half or fully closed to control the temperature passively.
You have _motorized blinds_? Seriously, how big is your house that this isn't just a two-minute thing you do to go and close the blinds? Alternately, how lazy do you have to be for this to be something you'd invest thousands of dollars into? Can't even fathom how motorized blinds will hold up to a decade of children abusing them... though, most of the bugmen I've seen who get seriously into home automation are childless.
> And to know that I usually get home at a certain time (I'm not overly comfortable with GPS tracking options) and start managing house temperature again ~20m before I get home so it's comfortable when I arrive.
That's what my $50 programmable thermostat does. Do you really get home at totally different times every single day, to the point where no 7-day timer routine is sufficient? To the point where (well, not you, but others) consider the idea of letting a bunch of random companies GPS-track them for this purpose? Mindblowing.
> I'd like my house to automatically close all of my blinds and turn on the interior lighting at sundown each day
Or you could just turn on a light when you need it. Is the wall such a long walk away? Seriously. You'd invest hundreds into each lightswitch so you can control it from your phone, only for it to not work the moment you want to show it off to someone... versus just using the simple, economical, $2 lightswitch that has become a complete commodity item available everywhere and easily designed to last for a hundred years?
Talk about a sustainability nightmare.
> Imagine having a garden irrigation controller that polls rain radar data from the local weather bureau and uses it (along with a local weather station) to decide whether to hold off on watering the plants, in case it rains. And using the local weather station to decide how much (if any) watering is needed.
Imagine missing the point of gardening to the extent that you automate the whole thing instead of actually taking the time to do it, and reaping the psychological benefits of doing so.
> I want a smart home that actively makes my life easier,
It honestly doesn't sound like your life started "harder" if this is the kind of thing you think makes it easier.
