I bought the e2 in order to track energy usage, and it works very well.

The product comes in two parts: the meter, which clips around the live feed from your electricity meter and the display, which shows information trasnmitted wirelessly from the meter.

The display is intuitive and easy to use, and it can show energy usage in terms of cost, carbon dioxide equivalent or kilowatt hours.

The display can also be toggled to show how much energy you are consuming at the moment, how much you have consumed today, and what you consume on average.

The display has a USB connection which can be used to download information to a PC. The wireless range is good, so you can locate the display next to a PC at the other end of the house to the meter.

The elink software which comes with the e2 can be used to plot the information graphically for a closer look.

I'm very pleased with it, and would recommend it to anyone looking for a pseudo smart meter.

One further point, there was a monior problem with the usb connection on the unit I bought. But efergy's customer services replaced the unit promptly, and without any quibbling.

Overall, a very good experience

I brought the Efergy E2 a couple of months ago after reading some reviews for the E2 and it's rivals on various sites. All of the energy monitors had their detractors but the E2 got my vote because it came with the ability to download the usage data to a PC and graph the data.

The big question for me was always "does it really work?". The answer is sort of. Since I installed the E2 I've been keeping a record of the actual electricity meter readings versus what the E2 has recorded as my electricity usage. I've been comparing the readings at 5 day intervals for about 2 months now and found on average over the last 2 months the E2 has shown my electricity usage as 8.5% higher then the actually usage. The closest it has been to the actual meter reading over 5 days is 5%(higher). Does it matter that it is not 100% accurate? Not to me. At all times it has given me a good indication of what my electricity usage is on a daily on minute by minute basis. And that is what I brought it for. The fact that in tends to exaggerate my electricity usage a bit just makes me more determined to keep that instant KW reading on the display as low as possible. The E2 is very good at showing the impact of turning appliances or lights on or off. The only exception to this is when they are low energy lights of equipment such as mobile phone chargers. Frequently the turning on or off of such things goes almost or completely unnoticed. But I sort of expected that since they use such little power.

I was already in the habit of not leaving appliances in standby but I still wanted to see what the minimum electricity usage in our house was and whether we could reduce it. The monitor has opened my eyes to a few things I had not considered before.

This monitor was so easy to connect and set up. Definitely recommend reading the instructions first even though all is very straightforward. Everything seems to be working ok out of the box (not tried computer link yet). After only 2 days use I am already being careful what I switch on and off. Yes it is a little expensive but for knowing exactly what electric is being used I think it is worth while. And you have the average per day/week/month of "cost" "Co2 emitions" and KWH hours used. After reading several reviews I came to the conclusion that it was worth paying that little bit extra to get a better machine with more data stored and that was why I choose the E2 model. I forecast that it will take a couple of months to get really used to this machine and there after start seeing the benefits.

I've had this for a couple of days now and its really quite surprising how much power different items in the house use. After a surprisingly high recent electrical bill I thought it would help condition us to reduce usage.

Easy to install with a clip over the live wire and a quick synch of the receiver to the transmitter.

It was a pain (and a surprise) at first that the alarm for a power spike is set a little low. With the usual range of other electrical items in the house all on then putting on the Dishwasher and Washing machine at the same time the display suddenly spiked over the alarm level and it took me a while to figure out how to reset it, all the while the monitor bleeping away at me.

Probably the only disappointing thing for me is that the software that comes with it is solely logging software and not control software for the device to reset its values. All control of the device has to be done by press and hold of the buttons on the device - a bit clunky.

The USB cable sometimes takes one or two prods to allow the logging software to recognise its there. Something not quite right in the software.

These two minor gripes are all that stops it getting five stars for me. Other than that a great little product.

Of course my kids now hate me as I complain about the current power usage levels in the house and I'm now becoming more aware of power usage from devices on standby.
