Hi,

We are currently planning our new house, which is to be constructed
during 2004 (a bit of a hurry already =)). For the past few months I've
been diving into various HA systems as I'd really like to have e.g. full
lighting control at the house.

I've looked at X10, EIB, LON, DMX-512, iLight, Lutron, Vantage and a
few others that I don't recall anymore =). The trouble has been that I
have only around 5000 euros to spend on this (on top of the regular
electricity equipment & work), so basically all the high end systems
that are available in Europe are out of the question.

But finally I believe I have found a way to accomplish the lighting
control component (which to me is to most important) in a relatively
cost efficient way. The DMX-512 solution was proposed Marc Hult, who has
his own system described at http://www.yqcomputer.com/
originally with DMX-512 was that it seemed that dimmer pack prices were
still out of my range.

I managed to locate a manufacturer called Liteputer in Taiwan, which
seems like a relatively big operation (has also European distributors)
and which offers a wide range of DMX-512 products. I received a
quotation for their 4 channel dimmer and the price was only $100 or $115
depending on the model. Now it seems that I could achieve a really high
quality, hard wired lighting control system at a budget price.

Still, I have the lurking feeling that I haven't thought of
everything. Thus I took the time to diagram my system and I put it
online at http://www.yqcomputer.com/

I'd like to invite you to visit the page and give me some feedback on
how to improve the system (and flat out say that it won't work, if it
doesn't!).

Thank you for taking a moment to help out!

how do you plan on doint the PDA remotes, i was thinking of the same thing

There are a number of tools available for PocketPC that enable the
PDA to work as a learning remote. I found out about a few of them at
http://www.yqcomputer.com/

Check out e.g. PDA centric discussion forum at:
http://www.yqcomputer.com/

In addition there is NetRemote, which is good for controlling PCs
remotely from the PDA http://www.yqcomputer.com/

Key is to have a remote that has consumer IR controllers rather than
the (1M limit) IrDA.

The Liteputer http://www.liteputer.com.tw/ has inexpensive 'architectural
grade' ISO 9001 certified lighting equipment some of which is CE listed.
The Chauvet 4-channel unit I mention on my web site is CE listed (at least
mine has a CE sticker) http://www.chauvetlighting.com/system/pdfs/dmx35.pdf
At about $30 per channel for the dimmers only (1800 watts max per 4
channels) these are a bargain compared to most other commercial hard-wired
lighting. The Chauvet DMX35 and some Liteputer units have both 0-10vdc
analog and DMX512(an RS-485 variant) inputs.

The analog inputs permit one to solve immediately a principal obstacle to
using DMX512 in the home -- namely the lack of commercially available
controls suitable for residential ("home") use -- because one can readily
make switches and dimmers using low-voltage toggle switches or
potentiometers to control the lighting with analog controls.

But DMX512 is not for everyone because of the lack of systems adapted to
home use means that the adopter is left with much hardware and software to
be designed and built.

I've expanded my home's DMX512 system to include battery-backed low-voltage
dimmers and custom low-voltage track lighting. Maybe I'll be able to add a
write-up of these to www.ECOntrol.org this weekend.

I've been giving some thought to using a dimmer like this in HA
projects, because of the cheap per-channel price. However, I wonder
about a (Canadian) code-compliant way to hook them up to a hard wired
circuit. Can you have a plug on the end of a permanent circuit, to
plug into a dimmer like this?

I don't know Canadian code but here's how I have done this in US locations.
Connect a length of SO cable to the feed line of the DMX unit. Plug that
into an unswitched outlet. Rig a small feeder box with Edison-plug ended SO
cables. Plug these into the controlled outlets on the DMX device.

It sounds Rube Goldbergesque but it's an effective way to utilize
plug-connected devices to power household circuits. We did this with a 3KVA
UPS in my home in CT. The UPS sat in the ba *** t. My office PC's and
peripherals (except one laser) plus two desk lamps were plugged into
standard wall outlets. The outlets were all UPS protected. I did this
because the cooling fans in the constant-on UPS were loud and the unit added
too much heat load to my office. I copied the method for a similar
DMX-controlled outlet box which I used for a couple of years in my church.

I don't see why not (as long as you're using CSA listed plugs/adapters).
Granted it's a bit "less permanent" than the manufacturer intended, but as
long as you don't exceed the recommended loads, I figure you'll be OK.

> I don't know Canadian code but here's how I have done this in US locations.

So the suggestion is to plug the dimmer into a conventionally wired
outlet? Each run for a light would terminate at a junction box and be
converted to a flexible cable, which would be plugged into the dimmer?
That makes sense and sounds perfectly reasonable to me. I wonder if
there are any (code) issues with grounding though -- i.e. I could
envision a requirement that any permanent fixture has a ground that
can't be casually disconnected.

I suppose it would be a good idea to discuss such a plan with a local
inspector first, since it would be quite different from anything
they'd routinely see. I do hope this method would be acceptable
though, since these dimmers are so much cheaper than any of the
hardwired ones.

Thanks for your insight Robert.

Good question. I forget where but I read in the code once that the ground
conductor can be interrupted *if* the means of interruption simultaneously
interrupts all the hot leads. Needless to say, a plug-connected cable would
accomplish that.


Absolutely. I would get a box and set it up on a bench, together with a
dummy panel wired according to the plan. Some inspectors are just retired
electricians and may not be able to envision what you're proposing without
seeing it in front of them.


Well, give it a shot with the AHJ and let us know how you fare. I'm almost
certain that if you only describe it he'll turn you down flat. If you can
show him what you have in mind you'll stand a much better chance of
convincing him it's OK.


NP. Best of luck.

Robert L Bass
