Your mobile phone
will soon allow you to switch your domestic electrical gadgets on and
off – and cut your bills – from anywhere in the world
By Miles Bignall
You get out of work early for once. How good would it be to be
able to turn on your central heating before you get home so it's all
toasty as you step through the door? Or you left for work in a hurry,
and are worried that the hair straighteners are still plugged in. What a
relief it would be to turn them off en-route using your mobile phone?
It might sound like something from Tomorrow's World, but both prospects are closer than you think.
In
the next few months British Gas is set to start the first big trial of
"smart home" technology, and, if all goes well, it plans to begin
installing it commercially in customers' UK homes over the next year.
The
final price is still to be settled, but the company hopes to bring the
package in at under £200. For that, consumers will get the technology
they need to create their first "smart home", although they'll need to
pay extra for any smartplugs that allow you to turn off appliances
remotely. These cost around £25 each.
The service is likely to
excite gadget fiends and those hoping to reduce their gas and
electricity bills. Buyers should easily save the installation cost
through lower bills that result in not heating their homes when they are
not there.
At its heart is a control box that is linked to the
home's broadband hub. Users have to upgrade their thermostat to a
(supplied) digital model, but apart from that, it should install in
almost every broadband-linked home.
It effectively lets you talk
to the central heating system from anywhere in the world. You can also
use it to turn on, or off, other key appliances using the smartplugs
that send and receive messages wirelessly to the central hub.
The
technology to make it happen already exists. British Gas has set up the
system in a mock home in its laboratory at its Staines headquarters, and
a small group of staff are testing it in their homes.
This week
Guardian Money had a sneak preview of the system that has been developed
in conjunction with AlertMe, a company in which British Gas owns a 20%
stake.
Sitting in our London office we were able to turn the
heating and lighting in the Staines "smart home" on and off. The service
has a dedicated web page which showed us which appliances had been left
on.
We were able to see the inside and outside temperatures,
turning the heating up and down accordingly – a boon for those who fear
their partner overheats the home while they are at work.
If you
don't have a smart phone, the system can be just as easily controlled
with a basic text message sent from a standard mobile or any PC.

Paul
Grosvenor, British Gas's head of innovation, and one of those who has
been using it for the last year, says that he has definitely seen lower
gas and electricity bills as a result of the tests: "Consumers are
increasingly demanding the ability to do more with the latest
technology, and we see 'smart homes' as the future. This technology
gives you the ability to conserve energy because you use it more
cleverly. You are in control, wherever you are."
He says he
regularly used it last winter to change his heating settings, even
turning on the system while he was away to protect the home from
freezing during the really cold spell. He says he also found it a much
easier way to set up his boiler timings than the original complicated
system.
British Gas says the system will eventually have the
ability to be customised. With smart key fobs it will be possible to
configure it to shut down every appliance linked to a smart plug, plus
the heating, when you leave the premises.
In the long run, it will also be linked to the home's smart meter, although it will also work with a conventional meter.
Along
with the other big power companies, British Gas is already in the
process of offering smart meters to every customer as they have their
old ones replaced.
These are read remotely using the mobile phone
network, doing away with the need for a call from a meter reader. They
will also do away with estimated bills and can be linked to the latest
in-home displays, that show householders exactly how much power they are
consuming at any one time, both in kilowatt hours and, more crucially,
in pounds and pence.
Leave too many appliances on, and the smart
meter display will show a red warning light – great for those with
children who tend to leave everything on.
Meanwhile, there is one
drawback to the introduction of a remote control heating system – it
could promote "couch potato syndrome".
Grosvenor is ashamed to
admit he has used his mobile to turn up the heating from his sofa,
instead of walking over to the thermostat.
"If you're lying in bed
on a Saturday morning and the heating's gone off, it's very tempting to
send a text to turn it on again rather than going down into a cold
house," he says.
