Matt, Jay.
In short - Indigo7 is an outstanding (long awaited) release.
Never seen any major upgrade (well, except the company I'm working in - Nutanix ) without complications.
The only smarthome controller product which is nearly flawless.
My house is a big playground (like Russians saying - Small boys - small toys. Big boys, big toys. ) for me.
I've got >300 smart devices (nearly _everything_ is automated) and virtually all availible (modern) smart technologies in the house. It's all managed by Indigo. And (fantastically) it works fine.
