Thanks for the reply Neuro.
For HVAC automation, I use Johnson Controls and Schneider Electric. They're both simple to do the engineering for and easy as pie to program. Between those two alone, there are so many processes going on in my city alone at any given minute.
I want to merge over to home automation as a profession, though. Frankly, I could care less what this valve is doing or that pump is doing, it's boring.
The typical companies - Crestron, Control4, etc. seem to want you to go to whatever school or factory it is to get trained in it, and frankly I'm not sure it's worth it to be running with the trend.
I like the gear you mentioned, and if ELK M1 and CQC can work together well, I'll use them. But having experienced it in the commercial world, there's always some "well this guy doesn't always like to talk to that guy" bug or glitch that will make life a royal pain for some time. If there's a combination - like those two - that work very well together, your answer saved me weeks of dry reading forums.
