Gotta admit, pretty cool! I'm just like.. My interest in smart home stuff is near zero; am I alone?
I think it's just an extension of my not caring to "tinker" with my professional workspace. I have all stock OS backgrounds, always preferred a GUI editor/IDE. Barely any customizations that aren't tied to significant velocity improvements.. IDK. I'm not a "space" tinkerer; physical or digital.
I have kids, and I have to leave the house quickly, so being able to set the house for "away" mode or make sure you shut off all the lights when you are all in bed is really nice.
Adding off-peak controls for electrical devices, water heaters, thermostats, EV charging, etc just makes sense so you don't have to think too hard about it.
I also really enjoy setting lighting for different moods - specifically when watching movies, and that's easy to do from the couch :)
I just like being able to control my lights and thermostat from my phone, I’ve never bothered with higher level automation outside of having a lamp turn on at dusk automatically lol
I have a time of use electric plan and adjust load (grow lights, dehumidifier, AC, battery backups) at certain times to save money. Smart home can be pure tinkering but it can control some pretty practical things.
You do you though, mechanical outlet timers work perfectly well.

I never was interested in the tinkering side. The functional side has been very handy.
For example, smart thermostats reduced the heating bill 40% while leaving the place warmer where we actually are.
Smart dimmers on lamps let you dim them in the evening, or turn all the lights off with one push.
Your use cases may vary and the answer may be none do it but a good level of smart home things are quite practical.
