I was looking at this
http://www.amazon.co.uk/Single-Switc...im_sbs_light_3

It seems to be a ceiling light with a switch that controls it
wirelessly, rather than with a cable looped in. Why isn't that used
more? I'm looking at some major electrical rewiring, and this would save
an awful lot of chasing out the walls to drop the cables down to the
light switch. Compared to the cost of chasing, making good, and redecs,
this is only £15.

What am I missing? Why isn't this done routinely, even for new-builds?

I guess because at some point down the line, like wireless doorbells, when
it stops working you then have the aggro of not knowing whether it's the
bell/bulb or the battery in the transmitter.

Having said that, I retro-fitted two switches like this to save a hell of a
lot of aggro when I wanted to reposition the switches and they'd worked
perfectly since. I would certainly use something like this again in
similar circumstances.

You want to put a battery in every light switch in a new build?

I'm not totally convinced of the reliability and battery related hassle over
"proper" fixed wiring. However, I'm giving it serious thought for outside
lights - driveway and garden and maybe pond. Then those become a simple
radial circuit for power (which is enough digging as it is) with some radio
switches indoors. Good candidate for a pocket remote and one in the car too.

The battery hassle there is limited to probably a couple of banks (front and
rear doorways) and if it goes wrong, your toilet for example is not blacked
out!

You can avoid the battery issues:

What you cannot avoid, it seems, are the cost of purchase issues.

I'm extrapolating from our wireless bell push, which has lasted on its
original battery for around 10 years. That gets pushed on average 3 or 4
times a day, I guess. Our kitchen light switch probably gets toggled 10
times as often, but most others in the house probably the same as the
door bell. So, I'm not sure the battery hassle really would be, IYSWIM.

Years of experience of wireless links of all types says you only use them
where a cable option isn't practical.

It's also a vast number of batteries to need regular replacement in the
average house.

I also doubt it can do two way and multi-way switching for halls, etc.

I'd have thought two- and multi-way switching would actually provide the
greatest benefit in terms of less and simpler wiring.

But agreed about batteries - if the kit needs them.

Basically because most arent aware of that alternative.

Nothing.

It is with the X10 system.

even for new-builds?

The saving isnt as great with new builds.

I have a "Celect" wireless C.H programmer and on a couple of occasions
the final "stop calling for heat" event of the day has not been
received,
and the heating as stayed on all night.

You would think that it would repeat the command at intervals but it
doesn't seem to.


The biggest joke are wireless PIR sensors for a burglar alarm.
