+1 on Lutron Caseta. Another plus with them as that you can get the remote and create a 3-way switch for your lights if you don't have one. I had the living room switch at the front door only. I changed the two gang wall plate at the kitchen to a three gang wall plate and mounted the remote in the wall plate. It is so thin that it can just set against the dry wall and no hole is needed.
I wanted to add 3-way switches to a few poorly-designed circuits in my house. I dislike the design of most smart switches, but this is what I went with after looking at a lot of options.
