How to set up the Owl meter electricity monitor

The Owl energy Monitor, or smart meter, consists of a (1) magnet sensor which fits round a wire in coming out of your main electricity meter, (2) transmitter which is attached to the magnetic sensor;
And (3) a completely separate little meter which you carry round the house and note the change in reading as you turn individual items.

(Note added in Jan 2009: These smartmeters in January 2008 have been made available for loan free at York library)

Normally the magnet sensor clips onto one of the leads coming out below your electricity meter in the fusebox cupboard.

However a friend, Arthur Lupton, has made a gadget allowing the Owl to be used on individual appliances. This useful for demonstration purposes. The gadget consists of plug, socket and two thick insulated separate wires connecting them. You can see this gadget in detail in the picture which is below the video. Watch!

Here is Mr Lupton's extra plug and socket. Note the two wires go separately from the plug to the socket.



















The sensor clips round one of the wires.














Here you see the sensor attached in my electircity meter and fuse box.
































Dave Tayler used the Owl for his house - and was amazed by the electric power shower result - especially as members of his household enjoy long sessions in the shower!

Thanks for letting me print your data, Dave!
