How many of us here are former CQC users? Sadly, I am still hanging on to my CQC system. While a lot of it is "broken", it actually still does most of the triggered automation that I needed mainly lighting and HVAC changes based on my alarm status. It basically just silently does it's job without any user interaction. I don't use it for GUIs anymore as all the weather and other "cool" stuff is broken.
I have HA loaded and running on a VM and I have started to play with it in a "lab" environment. I just haven't had the time to really dedicate myself to learning it however.
