I have nothing automated in my life, that I know of? I don't have a garage; the door to the house has a key; the lights I turn on with a switch; no Alexa, don't use Siri... I am not exactly opposed to automation, but I am hesitant to share even more demographic data to cloud services.
Problem is, it comes with a ton of headaches.
The cloud is a problem, as you noted, but also a bunch of fiddily, unreliable software, firmware updates that go haywire, and apps that are tied to iOS and will stop working with my physically installed home hardware if the manufacturer ever stops treading water and fails to update for the latest breaking iOS update.
Home automation could be simple, reliable, and future-proof. It’s really not, though.
