I just set up an iPad as my Homekit Hub and want to switch to an AppleTv when I get one. 1. Will this be as simple as disabling the hub feature on the iPad and enabling it on the AppleTV? 2. My older AppleTV would go to sleep and it would take a but for the remote app on my iPhone to connect to it. Does this same issue arise when using AppleTV as a hub? Is there a delay before it wakes up or does it not need to? Thanks.
