It's like you're purposely describing the least useful application of smarthome devices.

Setting up geofence triggers, time/event-based triggers, etc. is the real power of smart devices. I have automations set up so if I arrive home when it's dark, lights in my house turn on automatically so I don't have to fumble for light switches. I have motion sensors so if I walk into rooms, the lights turn on automatically and then turn off after I leave. I can set up schedules to turn lights on and off while I'm not at home so my house looks occupied.

Also, with Apple Homekit, there is a control center widget so you just swipe up, tap home and your "favorite" devices are very quickly accessible from anywhere in the world.

I use astronomical timers for outdoor lighting and indoor night lights. The rest of your uses look more like “because I can” and are not filling an actual need. Besides, my pets jumping on and off furniture would trigger those senors more than I care to admit.
