I’d really like to put Homekit-compatible smart switches in the condo I’m buying, but have absolutely no idea where to start. I’m surprised by how little information there is out there - I don’t see any kind of simple guide. It seems like I should go with Lutron, but it’s not clear if I should get Caseta, RadioRA, or what. After I settle on a product line, do I just buy the switches? Do I need a hub?
