Hi Marc, "Is this also true of knx or are their licensing issues (there are intrinsically none with DMX)." The Konnex association only makes the certification of the products, but for that you must become a member. However you can build products on your own...

"Can you provide example of residential 110 VAC Lonworks/Lontalk-compatible
Can you quantify what you expect as cost of dimming outputs?
Pfft, future-proof? Hell, LonWorks is PRESENT PROOF!
LonWorks was/is a great idea that they utterly failed to implement at a residential level. It might be great for industrial purposes but it has not place in the home. At least not with their utter lack of reasonably priced and readily available devices suitable for the purpose.
I have degrees in automation and robotics and can say that I would do it all myself from scratch with a wirless laptop ot tablet and some remote modules, but for the average user I would say your best bet is multiplexing everthing you can or wireless control to everything, thatway everything you forgot to do when you set it up is still an option.

Having Degrees and telling people that you have them the first time you talk is not very good, do you have any experience?
Going wireless is not good due to reliability problems with interference and distance Using a laptop or any central system as main control is madness distributed control is the only way to give resilience. I am sure no one wants to wait for the laptop to reboot to turn on a light. Systems like Konnex and C-Bus have this distributed control

Hmmm ... Dr David Nelson -- who designed computerized instrumentation for experiments in nuclear physics in the 1960's, was a designer of PRIME Computers, co-founded Apollo Computers (later sold to HP) and then started Savoy Software and designed and wrote CyberHouse IBM PC-compatible home automation software -- states that he has installations that have run continuously 24x7 from 1998 to date. Does his experience seem adequate to you? Where is the "madness" in his MS-OS, PC-based solution?
Dr. Nelson makes available an extremely lucid beginning of a book on concurrency in computer applications and its application to event-based home automation software design. Highly Recommended (slow download):

I have run CyberHouse from Fall 1999 with no failure that I know of ever from the software or OS. I received a free, full-version integer (3.x to 4.0) upgrade as recently as this February. It has been hands down the best software value for a major piece of software in 25+ years of dishing out $. Folks that listened to the hardware bigotry and hawking software vaporware in this newsgroups beginning in 1999 missed out on a spectacularly good, long ride ...
And this (Cyberhouse) software can be modified to add and subtract devices on the fly, and change rules on the fly -- no reboot necessary. In contrast, it
*is* in fact the distributed systems that use (eg) ladder logic that *must* be stopped to be reprogrammed and then restarted/rebooted. This applies to Ocelot, security panels and most "distributed control" devices. One of the most hilarious claims made here in comp.home.automation is that 'you program the Ocelot _once_ '.
(Clipsal is a notable exception that allows devices to added or subtracted on the fly. Was that your point?)
Well "ladder logic that *must* be stopped to be reprogrammed and then restarted/rebooted" WRONG I have rewitten systems while still running over the last 20 years You do not know what you are talking about
Both Clipsal and EIB have simular functionality but EIB has a choice of
120+ manufacturers Why so many manufactures are they all stupid or is it good
If you have an argument atleast make sure you are correct in you statments
If I write: "people who can't read", does that mean that "all people can't read " ? .
Apparently I wasn't clear enough. One part I wrote that wasn't clear/read/understood/responded to was: " This applies to Ocelot, security panels and most "distributed control" devices" [used in home automation in North America].
Are you are claiming to be able to reprogram an Elk MM443 or Slinke on the fly? Good luck!
I didn't discuss European EIB, did I? The original poster is in North America, not Europe, and the vast majority of all posts and discussion in this newsgroup concern North American homes with 110v systems, subject to NA building and other codes. Clipsal pertains because a major US distributor has announced that they will distributing Clipsal in NA this year. European Installation Bus (EIB) is not in common use anywhere in North America as best I know. This has nothing to do with anyone being stupid. It is a matter of different markets, prevalent codes and other regulatory requirements, and household line voltage (220 v 110).
What I wrote is correct, but I can see how it could be misunderstood. I did not say that all ladder logic or other devices had to be stopped. I specifically stated that (eg) Clipsal could be updated on the fly. That is not the case with many HA devices in common use in NA that are the subject of discussion in comp.home.automation. European Installation Bus (EIB)is not used in US and Canada.
