The way devices and scenes are presented on the iPad screen is not intuitive and difficult to quickly see. I went through and created icons for every device and scene. But, they do not appear anywhere on the iPad like they do on the iPhone. This is a big deal, because the iPad screen shows a bunch of pretty switch pictures with no useful visual information about state. The iPhone representation smokes it.
Additionally, all of the pictures are SwitchLincs and I have ToggleLinc. Just from an aesthetics, I would much prefer seeing the devices that I have in my home.
