It's dead in the water from day one for home automation, the reliance on the cloud has done that.

"Garage door opens, turn on lights"

If this all happens locally then fine, but it doesn't in the imp world.

if your Internet is down or the imp cloud is down its not going to work.

It's like the inverse of that old saying "the lights are on but nobody is home".

A local mesh system for home automation seems a much better bet to me.
