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.

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

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 bought this product over a month ago because I recently received a high electricity bill and wanted to track down the cause of this. Identifying the source was proving difficult, because although I could identify the circuit many appliances had 3-pin plugs that were difficult to access, so the 3-pin type meters were not practical. Using this product I was able to identify that the under floor heating in my study had a faulty thermostat/timer. This was causing the heating to come on every few minutes for about 30 seconds drawing about 3KW of energy - clearly displayed on the Efergy meter. You could hear the thermostat click around the same time the Efergy meter showed a surge in current usage. The floor was never that warm to notice the change (especially with slippers) and the thermostat was set to 5 degrees to disable the heated floor, so I would have never thought that this would have been the cause of the problem. Anyway in little over a month my Efergy has paid for itself.

On the plus side the monitor is very compact and with the clear instructions provided the sensor is very easy to install. It was one of the few products to come with software and a USB lead to allow you to connect it to your PC and analyse the comprehensive data that it logs. The backup file that you can create with the software is in .CSV format so you could even import your data in Excel or some other program to plot your own graphs if you were not satisfied with the software (which should be more than adequate for most needs).

The only negative I can see with this product is that under Windows 7 you have to run the application with Administrator privileges - Why?! No application should need this level of access to run. I suspect it writes data to the installation directory instead of a directory under the users profile. This is something that Efergy need to fix with the next release of the software.

But on the whole I must stress, I am very pleased with this product.
