# CC Server and Web Frontend to display dataThis is a place to store good pointers and collections of information which are useful to people who want to get started with their new Current Cost.


What is it?


According to currentcost.com the Current Cost is "a highly accurate second generation home electricity monitoring device." To you and me it's a consumer device for finding out how much electricity you use and how much that's costing you.


How much does it cost?


RRP £45 (but currently discounted to about £30) from ecogadgetshop.co.uk. However these have the older firmware, so buying the one from ebay is a better option. Currently being given away free by Sky. See www.sky.sky-environment.com.


How does it work?


The Current Cost (CC) has two parts:
  1. a loosely-fitting clamp which you put around one of the cables leading to your electricity meter, the clamp is attached to a power pack which broadcasts readings from the clamp to...
  2. ...a display which sits on a desk or next to the telly in your living room. This plugs into the mains.

The clamp uses electromagnetic induction to measure the flow of electricity through the cable it is wrapped around, which is broadcast over (433MHz) radio to the display unit.

But such a clamp monitoring technique however does NOT show true consumed power (Watts), responding to the load's apparent power (Volt.Amps) demand, which can lead to significantly distorted readings on "reactive" loads.

Although most homes historically have resistive electrical demand, this power factor (PF) issue is of increasing importance domestically when measuring standby appliances, motors, computer power supplies etc- you will actually be consuming less energy than clamp based meters inform you about !

Do you need a replacement for Google Powermeter or do you want to graph your production/consumption data over time?

AMEE can store your energy, and calculate the carbon footprint of your consumption
