You seem like the person to ask, so... did you write a "Stavros Home" skill (to borrow from your SN) which can do all of that centrally, or multiple skills?

The problem I'm finding is I can train myself to remember about 5 skill names that can each do one or two things, but thats about it. I'm wondering when I write my own, if i should just have a central skill for my house. Also how did you link into the Chromecast? I have a chromecast buried in my Vizio Smartcast TV and i'm wondering how i can link it in.
