This is true, unfortunately she (and myself) have been in too many
situations where we have seen early adopters of new plant automation=20
products have serious problems. So I'm afraid it's because of the
Electrica=

Engineer status that we tend to be a bit cautious.

Unfortunately, forward thinking also means looking at the worst case
scenarios ;-)

In a few years time intelligent lighting will be the norm and there will be
sufficient supply of  electrical contractors out there who will have the
skills to install / maintain these systems IMHO....

I'm afraid SWMBO will not be swayed on this (the house must be wired as
standard to revert back if required) and in a way she has a point,
Her argument being: Just say we wire the house with a bus system and it
works perfectly for years and then we sell it, somewhere down the line
something goes wrong, the buyers call out an electrician who takes one look
at the system and either doesn't know where to start or charges a fortune
for non-standard work.

The other issue is building regulations, where do we stand here when we
com=
e
to get the wiring signed off?

I've heard that Siemens are claiming that their EIB system (Instabus, I
think it's called) is the cheapest home automation system on the market.

Why would you want to run power as well as a bus system?
Bus lighting is only going to get more popular.  Look at car electrics.

A quality professional lighting system (ie one that doesn't need
"tinkering") is one of the few Home Automation items which may
actually
prove to be a selling point in a house.

Last time I heard EIB was very hard to do as a DIY install.  It needed

changed).

CBus can use totally standard CAT5 cable.  It's bus can be Star or
Daisy-Chain or a combination.

There's nothing to stop you installing CBus AND putting mains cables in the
walls too (seperately of course).

With the UKs support of CBus growing..and new products like the Alarm, the
RF Switches and the Multichannel CBus zoned amp all due shortly, CBus is
hard to go past.
