Sensoring behaviour

The EnergyEGG from Glasgow-based TreeGreen is a clever device that switches off appliances when people have left the room

The EnergyEgg, on sale at John Lewis, is great for households with gadgets galore and inhabitants prone to leaving everything on standby

This sweet little Wi-fi egg has a unique and sophisticated motion sensor that will switch off appliances linked to it when people have left the room - saving energy on electrical items which would otherwise have remained switched on. Developed by Treegreen, a Glasgow-based green technology company run by Brian O'Reilly, the egg knows the difference between a human being and a pet, and between an empty room and a sleeping person. So if you're snoozing on the sofa, it won't take your mistake your lack of liveliness for you having left the room.

O'Reilly, a former teacher and software consultant, says the idea for the EnergyEgg came because he was driven mad by his three daughters continually walking away from their electronic devices without switching them off, such as computers, games consoles and radios. He baulked at the wasted energy and was annoyed that the family's electricity bills were higher than they needed to be.

EnergyEgg packs from John Lewis cost from £40

'We want to help people save energy and money without having to completelly change their behaviour,' he says, stressing that however good people's intentions, they all too often go back to their bad old ways... such as leaving things on standby.

Most households will probably only need one or two eggs, one for the living room and another perhaps in kids' rooms. You only attach devices to the special plug that you want to be turned off at the mains when you leave the room, and you programme the actual egg to switch appliances off between five and 30 minutes after a room becomes uninhabited, according to what suits your lifestyle.

An EnergyEgg pack costs from £40, money you should have recouped in lower energy bills within six to 12 months.
