IMHO... if it works it works. I've never thought automation had to be of a certain brand or flavor. Or of a certain level of technology either. I am all for mix-N-match. I want ALL the advantages! From clock motors.... to whatever latest-greatest app gizmo gives me the most.
In general, I agree - but as computers have become ubiquitous I think there's an understandable desire for integration to simplify control, scheduling, etc.
I'd say computers
had become (past tense). Computers became ubiquitous here.... with the release of Windows 98. Home automation became "smart" with the addition of a PC running 24/7.... quite a few years ago (back with win95). And, X10 really helped lead the way IMHO!
I myself have been running an automation PC for about a decade. I actually run two computers for automation (one is a CE version tiny PC)... but that's a whole different subject. I have a server-like shelving set-up in my man-cave. I used to call "my room"... my office... then the Nerd-nasium... now it's my man cave.
I don't even have a desk in there anymore. The one last full-sized PC I have setup (I have others in storage)... connects to a long range keyboard/mouse and HDMI connects to a 46inch TV/monitor. I can use the PC while seated at my bar-height table and chairs. Or even while on a bicycle mounted to a trainer.
For a long time I advocated the re-purposing of old PC's for home automation. And I still see nothing wrong with keeping the "old stuff" working. But there is a lot out there... that still can be done. But to accomplish what can be... we have to be willing to let go of what we already know how to easily do. And then.... fearlessly imagine what can be.
Everything changes! Not only has "my room" changed much of what I used to really need a PC to do... I can now easily do with a tablet and/or phone. My automation would/could be better if cloud based and controlled through tablets and phones. I like better!
