When I re-wired this place, I made sure hall etc
switching
was
easily
available from everywhere it could possibly be
needed.
Which
means
5
switches for one of them.

I remmeber planing to put thin or thick ethenet
cables
in
everyroom.
I
wired speakers from the frontroom across the loft
down
into
the
kitchen
and bathroom with swtiches so I could switch them off
and
on
well
that
was in the 80s, how was I to know that I could carry
a
walkman
type
device which could store more music than I owned.

Pray tell how having a walkman replaces decent speakers
in
a
room?

Where did I say they did ?


Try learning to read first.
"I could carry a walkman type device"

And what you use to specify what you want to listen to is
quite
separate to where the sound comes out speakers wise too.

Yep so how does he use his music centre from the kitchen or
bathroom.


No I have PIR which switch on when I go to the loo.

And no reason why you can't have that for the entire
house so the system turns the lights on and off completely
automatically because it knows where people are at all
times.

what is the it that knnows where everyone is at all timnes
?

PIRs strategically placed. May well do dual duty for the
alarm
system.

Cats and other pets trigger them too.

Trivially easy to organise them so that they dont.

How do you organise a cat ?

You organise the PIRs, not the cat, stupid.

How do orgnise PIRs so cats don't trigger them.

Alarm systems do it all the time. Same
with small rodents like mice and rats too.

by NOT detecting in those areas.


Which is the area close to the floor so that the human would
have to be lying on the floor to not be detected, stupid.


A PIR can't detect between a human and a cat well the cheap ones can't.


So you dont get a cheap one if you want the PIR to be used to work out
when a human is in a room so the system can work out whether the lights
need to be on in a particular room or not because someone is in it, stupid.

Completely irrelevant to whether it works fine for lights.

Hence false triggering of lights.


Doesnt happen when done properly and is no big deal
with modern low consumption LED lights anyway.


consumption isn't the issue here.


Corse it is, if there is a bit of false triggering with LED lights, its
no big deal because the power used is so low when that happens.

Doesnt have to detect who you are, ALL it has to do is
detect that its a human and not a cat or mouse or rat.


Then how does it do that.


By not bothering with stuff that is too low to the floor.
