I think a connected home is never a need but more like a luxury anyways.
But once you get connected you will never want to go back.
I rarely use the wall switches to off stuffs now. Like on my bed, I usually just use phone or "Hey Siri" to turn off my bedroom lights.
When I leave home, I'll be able to check if the doors are closed and locked properly, so do the windows.
And I don't have to bring my keys when I leave or enter the house. Zero keys from entering the gate to the main door.
I can have the lights on automatically when I go up the stairs.
And you're right about the touch part, I had program one switch near the stairs to turn off everything downstairs when im going to bed.
I can open the gate + door for a friend when I'm in my room with monitoring from CCTV.
When I turn on the Tv, I have the lights dim for me and the Tv backlight on (how troublesome to do this by hand) and if you have smart blinds/curtains, they can turn off too + adjust the temp in the room.
When you turn off the tv, the lights can be brighter again
I think we reached an era where everything is modular and reprogrammable so everyone can have automations/scenes that suit their need
Hahah I think it depends on creativity and having a more unified connected home where different brands work together, so you won't be restricted by smart home products of one ecosystem.
Connected home is a lifestyle not luxury. 10 years back market as luxury but not now.
HOwever, home automation is not only a control device, use finger on switches or finger on mobile devices, this is only the basic.
It is a relation of sensors and actuators under a preset circumstances/ conditions. The logic like if ... then ...else ... else if ... etc .
