That's a pretty good idea. I have a Harmony Hub and it would be nice to trigger some functions just via the TV menu system if I was watching TV. Hue light control is an obvious one.

However, many of my already configured activities will change the state of the TV (turn it on/off or switch inputs) so I could see it getting confusing.

What would be really useful is Android Wear support for the Harmony Hub. Still no sign of that.
