London Lite Tuesday, 8 September 2009 17 my hometweethomeHousetalks toitsowner viaTwittersite A HOME where Twitter tells its owner when dinner is ready, if someone is at the door or even when a mouse has been caught in a trap has been unveiled. The 16th- century cottage is one of the most hi-tech homes in the world with hundreds of sensors linked to the micro-blogging website. Should anything go wrong, such as a light being left on, the house can automatically send a tweet alerting its owner, Dr Andy Stanford-Clark -- who has the job title of distinguished engi- neer and master inventor for IBM computers. Dr Stanford-Clark, 43, started reno- vating the Isle of Wight property five years ago, and realised Twitters poten- tial comparatively recently. My day job is looking at how objects can be linked to the web, so the house is a showcase for the technology, he said. Monitoring things can give us valuable insights into the cost of vari- ous appliances. Recently I was out and got a tweet saying water usage was higher than normal. I phoned home and my wife saw the garden hose had been left on. This can help us take steps to reduce energy bills. Mine has dropped by a third in the last year. These systems are also relatively inexpensive to set up -- a basic one would be 150. His system had to use wireless sen- sors wherever possible because the cottage is a listed building. It was a challenge, but relatively simple using technology easily available -- the chips used in Oyster cards, for example, said Dr Stanford-Clark. The house can also be monitored and controlled over a mobile phone. Its very convenient at times, he added. If Im on the way home I can turn on the heating.
