Well said! 
I would just modify the following point slightly:
Home Automation really still requires you are a technical enthusiast - with endless patience
I would say instead:
inexpensive full-featured Home Automation really still requires you are a technical enthusiast - with endless patience
Which is to say I don’t think you have to be a technical enthusiast to get a stable satisfying experience from either the very high-end systems like control 4 or the ones with a monthly fee like Xfinity home. But you are paying significant fees for that stability, ones that are well outside of my budget.
We also should acknowledge that the monthly fee midrange systems like Xfinity home have literally millions of customers now, for a total that is probably 4 to 5 times that of the DIY systems and growing. Yes, it costs $40 a month, but there are many willing customers at that price point.
Also, if you’re only looking for a few features, in particular just lighting or just a doorlock, there are a number of stable low-cost offerings, including Phillips hue, August lock, Lutron Caseta. These are mostly “set and forget” devices. They don’t require constant tinkering.
Smartthings, Vera, Insteon, Homeseer, Fibaro–these are trying to provide a control 4 experience at 3 to 5% of the upfront cost and with no monthly fee. That’s the problem that no one has cracked yet.
Personally, I had high hopes for SmartThings because of the Samsung tie-in. If it could function as a value add feature for Samsung’s high-end appliances and televisions, and the rest of us could come along for the ride, it might deliver much more than its DIY Price point would imply. I think to a large extent that has been true. I certainly don’t think SmartThings has been turning a profit over the last year.
It remains to be seen whether the television–based version of SmartThings gets stripped down to something much more limited in features but with more stability, or whether they really can get this horse to sing. We’ll see.
