Not sure if I'm just getting older, but the less things/complications in my home, the more peace of mind I have. Been watching the youtube LTT channel on his smart home and I feel all the things going on would drive me crazy.
This doesn't apply only to tech, but even for my next house (Looking into passive homes, least possible HVAC footprint, floorplan for minimal plumbing/electrical).
For me, a lot of that came down to making sure every automation I add is usable with the least amount of mental effort. For the longest time I didn't automate much at all and often questioned whether I needed all this or not, then we had a baby.
Now we have a button in his nursery that will dim the lights, start playing white noise on a Google Home speaker, mark the start of a new nap on our Babybuddy instance, then turn off the lights after 30 seconds. When I press it again, it turns off the noise and stops the sleep tracking. If we didn't have Home Assistant we'd have to do all these things manually multiple times a day. Instead it just takes a single button press.
It's a small example, but things like this will keep popping up, and I'm looking forward to making them easier.
There’s no law of nature that says you need to track your kids sleep and upload it to a could service.
