Having a look round the net, are the energy sensors all pretty much just as relaible?

Owl, Efergy, EON, Eco-eye etc?

I'm guessing not many will have used more than one manufacturer's product and all I can say is I have had the Efergy model for around 18 months - it's worked flawlessly and it has helped me save over 30% off my electricity bills.

I will say that these monitors are fairly in accurate - I have checked the usage shown by the energy meter and compared to my meter - it's about 20% out (low). I am assuming most manufacturers will be similar as the technology will be the same/similar. This doesn't really matter as I found it was useful for simply understanding where the energy was being used....

Hop that's of some help.

I have the efergy one and am really happy with it. I did have a problem in that after I changed the battery in the main unit it couldn't detect the sensor any more. I emailed them about it and got a reply within a few hours as to what to do. You could argue that it would have been better not to have the problem in the first place, but I was pleased to see it demonstrated customer services/tech support are on the ball.

i'm interested in one of these however i'm wondering if it will work on a tariff which is like:

first 200kWh in a quarter is one rate and after that its a lower rate.
this is not E7 though. Although i used to be on e7 and had the meter changed i still have two cables that come out of the main box into my meter and then two cables come out of the meter into my fuse box.
Would this mean I would need two sensors one on each cable before going into the meter?

The original efergy one I have will not give you the correct price for your overall electricity use with a two tier pricing system.

I would suggest that the cost is not really that useful because what you want to know is WHERE your energy is being used - find that out - and change the way you use those appliances or change to more efficient appliances (going from an old fridgefreezer to an A++ one saved us 25%), that's how you'll save money.

At the end of the day, you need to know what the energy you use a day is (i.e. kWh) if you reduce this number you'll reduce your costs however they are calculated by the supplier - and all suppliers are different...sorry if I am pointing out the obvious!

thanks! that actually explains how better to use the device rather than try and use it to verify my bill

Just seen an advert on the TV for tomorrow's Sunday People and they are giving one away for free (even the postage is free the ad said).
