The key is the voice control. Trying to do it via an app, a remote, or even remembering the switch UI isoften too heavy-weight. Being able to say just "Alexa, living room 50%" is very nice. Same thing with being able to turn off my bedroom ceiling lights without getting out of bed. Sure, is it required? No. Can I get up? Sure. Was it worth $50 for the smart switch? For me, yes.
