I think the company to look at is Philips. They really understand how to create appealing connected things. For example this article[1] that talks about their controllable color lights, cooking assistant and coffee maker, all controlled through an app to great benefit.

And once something is connected, bluetooth becomes a limitation - say you want to choose coffee type at the living room with your guests ? or you want to watch the cooking assistant while being at the kids room ? Considering that the cost of full connection should be similar to bluetooth in the best case scenario , why settle ?
