Some info on energy meters

This list of monitors includes some links to suppliers. It is nothing
like complete.

Plug In Appliance Monitors
I have tried these two:

Westfalia Wetekom Energy Cost Meter
£9.99
It has a small display and will not tell you average consumption as
the 'duration' counter only counts the time the appliance is on.

Plug-In Mains Power and Energy Monitor
£27.99
This was the first one we found from Maplin. It is often cheaper
in the shops!

of these:

Whole House Monitors
We have tried two.
Electrisave Wireless Energy Monitor
Originally known as the cent-a-meter in Australia and the USA it
has now been been replaced by the OWL. Although expensive, it
demonstrated that smart displays of electricity consumption raises the
awareness of the whole household.
£78.00
Efergy Smart Meter
The first of the cheaper units on the market. We have found them OK.
£44.99
Eco-Eye Mini Wireless Electricity Monitor
£39.99
The latest unit on the market, with a choice of displays. It has
added functions, with historical records and cost predications. A
computer interface unit is in development.
