I have an old house, where it location of a few switches are just completely illogical. One solution would be to install a few "smart" switches and a relay or two. If I want to stay secure and care the least bit about cost and privacy, there's no choice other than run an open source gateway solution, funnily enough it's also the only solution that will work with almost everything.
There's an entire cottage industry and hobby scene around making 3D print and modifications to Ikea, Hue and other switches so that they'll look like "the real thing".
