I was wondering about the various devices like "current cost", "kilawatt", and "owl" that measure your electricity usage. I know they have been discussed on here before and some people have said why do you need one of these when you already have an electricity meter, and there is some logic in that.
My electricity direct debit has jumped from 60-odd pounds per month to ninety-odd pounds. I think that's due to changes in prices rather than changes in usage, however I would like to see what I am using to see if there is anywhere I can tweak some savings. I think using one of these meters might be quicker and easier rather than read the "proper" meter every night or do mental arithmetic based on how many flashes of the LED or rotations of the disc (depending on your meter) there are.
Are these makes all much the same or are some models better than others? It would be nice to be able to view the data on the computer and it would be even nicer if the device logged usage so that I did not have to leave the computer on to download from the device in real time: that would only add to my usage!
