HA wiring

[Martin Greenwood <martin@xxxxxxx>]

I'm new to your list, I've been lurking for a few days and learning a
lot about Microsoft and Linux!!

Personally I think Microsoft is sh*t, but unfortunately we all end up
using it...

Anyway, on a HA topic (if that is allowed!)

I've looked thru some archives and a lot of HA web sites including
the excellent AutomatedHome site but I have the electrician due next
week to wire up...
I've read a couple of books, but they were a bit light weight and U.S
orientated.

So if I could ask a bunch of questions, that you all know the answer
to, it would be very very helpful.

Looked at Lutron and it is too expensive, are you all using X10?
Unless CEBUS etc is happening?

I'm looking at din rail modules for lamps, what is downside (if any)
of using all dimmable ones LD11U type rather than AD10 type.
I will use momementary switches as this looks easiest for multi way
switching. either MK or Clipsal
We have 4 floors so need to switch on/off 3 circuits on each floor!

For table / bedside lamps I'm could go for DIN LD11U+ 5A sockets or
LM12U plug type dimmers.
Does the LM12U buzz or get hot?

Do the DIN modules get hot. I am looking at about 18 LD11U's to
start!! I have two possible locations.

What about bathrooms, I would like light scenes, perhaps I could use
SS13 as it is not mains powered, inside the bathroom. I know that it
is intended to switch and dim three lights. I would prefer to use it
or something similar to select one of three scenes. This would mean
that the switches were just inputs to a controller rather than direct
input to modules.
Is it easy with a controller or PC to breakaway switches from lights.
i.e. one switch turns on light 2 at 50% and light 5 at 10%, another
turns light 2 at 20% and light 5 and 6 and 7 at 90%?

This way I would fix the logic of hall, stairs and landings by wiring
momentary direct to DIN module, but have switches inside rooms which
could be 'reprogrammed'. (To annoy visitors!!)
To support this is there a multiple momentary switch input to any of
the controllers that could support this.

Would anyone trust having only a SS13 inside a room and no REAL light
switches??

Are there alternatives to SS13 (It is still a bit American!!)

As you can see initial hit is power wiring, but audio etc is next.

Sorry for all the waffle, but it goes you a break from Windows of the
week vs Linux.

Last, but not least, is anyone with all this nerdie X10 stuff around
London / SE10 / Kent who fancies a beer, whilst I pick their brains!!

Thanks,

Martin
