Whew... that is a LOT of feedback in a short period of time!
Must be a lot of Insteon interest / focus / frustration / users / whatever. :huh:
As I've said before (to the irritation of some, I suspect), I've had great success with the functionality of Insteon switches. I'm disgusted at the QC... but not enough to move to the other platforms after seeing what I can do with the lighted buttons on KeypadLincs (as mentioned above).
The lack of other Insteon products doesn't bother me because I'd rather be hard-wired on security and irrigation and such - and I'd prefer a larger selection for many other solutions. I don't necessarily want a "one size fits all" HA control protocol until it is a full IP stack in every device using standards-based LAN/WLAN communication.
Using the Elk allows me to use other RF controllers and they control Insteon equipment as fast as if it were an Insteon RF device (using the WGL RF800 and many different RF keypads and such). The Elk controls the irrigation, security, and motion activation and such.
To that "KeypadLinc" thing, it's that ability to do n-way connections between all the switches and keypads - including designer-based feedback (not just system created) - that I don't see in current UPB or Z-Wave devices. Feel free to correct me, of course.
What I'm talking about is the fact that the lower-right button on all KeypadLincs in the house (a dozen or so - at least one per room / area) control outside lights and indicate the status of those outside lights on all the other KeypadLincs. Similary, the "espresso" button indicates whether the espresso maker is on or not. If the light is on in any of the KeypadLincs, it's on in all of them.
It's a little thing that I didn't think much of before I implemented it, but it's really cool to have now that it's there.
$.02 'n' all...
<_<
... all that said, I'm more'n a little tired of replacing failed switches, fer gosh's sake.
