Home automation enthusiasts as well as all other DIY types are alive and well and have never had more to look forward to.
I agree that DIY types are very much alive and well. I am a DIY'er myself! And I certainly think the best days of Home Automation may be ahead of us! But
I don't think the best of future Home Automation will be accomplished by the Do It Yourself-ers.
Traditionally... Home Automation was NOT plug and play. Being an old wire-twister [myself] was very helpful with my [DIY] Home Automation setup. But we've reached a point where the service providers like alarm company's, phone service providers, and even the Cable [service] providers can do more. Cloud computing options are only going to be compounding their capabilities.
Now home owner DIY'ers, or even a apartment dweller, can pick up a single use RF light switch, a couple motion sensor light switches, and maybe a timer or two and have a decent little setup. All pretty quick, cheap, and easy.
Or... if someone wants a more advanced setup... calling the alarm service provider, Cable company, or even phone service (depending on area) can get them darn cool stuff at a small monthly fee.
Things like: Answering your door bell (via a camera and intercom) using your mobile phone... from work or nearly anywhere else. Not that this can't be done by a proficient DIYer... it can be. But at what price? By the time we recoup any saving by not paying a monthly fee.... will advancing technology have made our equipment obsolete?
I mean... how far into the future do we really think it will be before home security cameras will be HD... or offer built-in face tracking and auto-zoom? My Web Cam has those features!
I really do understand the satisfaction of getting my hands dirty and doing my own stuff. I am big lifelong DIY'er and a believer that: If I can't fix it... I really don't own it. I was a network administrator and I am fine with using computers. And.... I still think we can do things ourselves that enhance our Home Automation. But I think the service providers have the upper hand here. I think they will be providing the best of what I want from home automation.
