I was able to add dimming capability to the lights in my rented apartment where it wasn't available before using smart lights. That was a pretty big benefit to me.
Unless you're saying because it is rented, the landlord won't allow you to install your own switches, though I'm not sure why they'd care as long as you restore it before moving out. I own rental properties and would definitely allow tenants to do that. Hell, I'd even do it for them if they asked.
