As someone who thought smart homes were just a gimmick but now has a reasonably complex HA setup; these are some of the things I use it for:
* Controlling items I don't have easy access to:
* AC in baby's room (as well as checking on temperature) while baby is asleep
* Subfloor ventilation fans and set up clever timers for them (I'd have to crawl under the house)
I also have a motion sensor connected to a light for the hallway which has logic that is a bit more clever than the out of the box motion-controlled-lights (e.g. it stays on if people are in the vicinity).
Other than that, the rest is pretty much gimmick:
Every blue moon I will change the light in the living room to bright purple for fun.
