I am literally working on this now. I jsut built a home and went with leviton switches and made the entire house smart with Apple HomeKit. I have tv's, audio, switches, pool, sprinklers, etc.. all on home kit. Was a breeze to install and so far working perfect. Many of the new hole house fans like quiet cool come with RF wireless controllers.
I think most of this woudl work and you can use from the app or looks liek two will work from home kit
