Bathroom project - Cbus style lighting system....1 room only though!!

["noel_pilot" <HA@xxxxxxxxxxxxxxxxxx>]

Hi all,=20

I've just started an intermediate DIY course at the local college
(wanted to know how to plaster so I can start chasing cables etc) and
I'm planning my first big project...my bathroom.

Plan to completely redo and obviously HA has to play a part.

I'm in a 2 bed mid terraced new build (2001) house so I'm not about to
put in thousands of =A3's worth of lighting for such a small house but I
would like to see what I can do at reasonable (!!) cost.

I remember reading way back about someone who had a lighting setup
whereby they have occupancy detection so lights come on automatically
but with intelligence, i.e. if its 0200 only turn the landing/bathroom
lights on to 15% or so so as not to blind you in your sleepy state!!

I love this idea and would love to be able to replicate it for this
project.

I can't remember who or what system that was (feel free to pipe up :)
) but could this be achieved through cbus alone without requiring
other systems to be on 24/7 controlling the logic?

For such a small scale is there anything else out there that could do
this? all I have upstairs is two bedrooms and the bathroom, one
bedroom is for a lodger and i'm not overly fussed by lighting
automation in my room, altho motion activated lights when I walk in
would be quite cool!!

I have a large loft above so could put power packs etc up there
without too many issues although I'm obviously going to need to have a
new electric supply run to the loft.

Being a bathroom I'm aware I'm running into Part P, am I correct in
understanding that work can be done by anyone but it has to be signed
off by a Part P electrician?

Lighting plan is for six small downlight/spots in the ceiling, at
present its just a normal bathroom, single central ceiling light on a
string pull switch that also turns on the extractor fan.

Plan to retain the fan albeit a different bezel and also add heated
mirror pads to prevent steaming of the mirror.

A 'cool' switch/touchpad/screen to activate the lights probably
located outside of the bathroom would also be a bonus!!

I'm in the very early thought stages of this and more posts will I'm
sure come over the coming months (I will of course take pics when I do
the job) but any thoughts re the lighting would be greatfully
appreciated at this point.

For those far more experienced in cbus could anyone just give me a
guide price of what I'd need to put in the dimmer packs needed and say
a saturn switch for just the bathroom maybe with expansion capability
to cover one bedroom?

Cheers all and sorry for the long post!!

Noel
