I think I am going to have to sit down, draw up what I want, what I
would
like .. and what my budget is ! (maybe cancel the last column and worry
about
it later!)
Thanks
Jonathan

Ah,
that's different then. Some ppl just want things that work, some want
to
make things that (may or may not!) work, some would like to be in the
latter category
but don't have enough hours in the day and thus settle for the former
:-)
Tony.

Yeh, I
had
looked at those, however, I wanted to try and explore the possibilities of
doing something home-brew perhaps, and trying to cut down on
costs.
Thanks,
Jonathan.

Jonathan,
What you describe doesn't sound especially intelligent at all -
and
certainly not difficult.
You can get, for example, a futronix P100 light switch for
about
150 notes that fits a 1 gang 47mm deep box.
These have two channels of 300W each and can store about 20
scenes
with each of the two channels at any one of 63 different brightness
levels.
In your scenario, you would simply choose a different scene
that
turned off some lights and left on others.
The switches can be IR controlled, or via on/off and scene
up/down
buttons on the actual units.
Of course, if you want more than two channels and/or want to be
able to control the lights in a more intelligent way than you have
described so
far, then these will probably not do the job, but they do meet the
requirements
you mention.
There are other controllers further up the price scale for more
sophisticated requirements.
Lutron and a few others also do similar devices. chect
out
letsautomate.com for some of them.
HTH,
Tony

Hi Ian + rest of
group.
Here is an idea I've
had
...
Initially I thought
about
using a relay board from mollyology.com .. then was advised about using
TINI
...
Perhaps this may be the
key
..
I want an 'intelligent
lighting system' .. that can control 6-10 lights (little 12v downlighters
(the
led ones.)) if I put say, 6 downlighters in my lounge, and I have 2 that
are on
the far wall, 'above' the TV .. I want to be able to turn 4 of the lights
off,
and leave 2 on, that will be dimmed to a slightly lower level (the ones
above
the TV).
However, in addition, I
want to be able to use a Pronto (be that with IR or RF) AND a set of
wall-switches to turn them off / on (not sure of how the wall switch would
be
setup yet.. how many switches etc) and last but not least, a pc interface
would
be fantastic.
While I'm on this
subject,
whats the score with 12v lighting and IEEE ... as I'll be binning 240v
lighting
(pretty much .) are there any 'rules' that would have to be conformed to
?
Any thoughts / help on
this
would be appreciated.
Jonathan.

I have a small circuit on my desk here, which is based on a PIC16
processor.
It has a *tiny* number of components, but can talk serial to a PC at
9600
baud.
This circuit has a light and a standard mains wall switch attached to
it.
Flick the switch, the light comes on, and the device sends a xAP
message
out
onto the RS232 connection to the PC. A xAP application running on the
PC
forwards this on to the Ethernet network, so that an application
listening
on Jenni's PC knows that the switch was just thrown, and the light is
on.
Jenni then sends a xap message from a controller app, saying no, switch
that
light off again.
The PC application sends the message on to to the PIC, which dutifully
obeys
the xap Message, and turns the light off. a second or so later, it
sends
anothe xap Message, to let any application on the network know that
the
light just went off.
It's a proof of concept, but when you consider that this circuit costs
about
£8, the bright future of xAP should be obvious.
The first version of the protocl has now been finalised, and we
need
developers to assist, and if you have a personal HA itch that
needs
scratched, now is the time to do something about it.
Trust me on this.
I am a complete noob at both Visual Basic and PIC development, yet I
have
working IC xAP hardware, and a Winamp Controller written. If you want
to
make it happen, you can.
Ian.
