## Description

The e2 has been recommended by PC Advisor and Mail Online. The e2 classic 3.0 is efergy's third generation of wireless electricity monitors. It includes an innovative software package so you can track your energy usage on your PC/Mac. The e2 wireless energy monitor updates in real time, so you can instantly see the impact of turning a light on or off, boiling the kettle or using your tumble dryer. It is extremely easy to install, set up and use. The sensor detects your electricity consumption and via the transmitter wirelessly sends information about the amount of electricity you are using to the display monitor. Through greater awareness users save up to 30% cost on their energy bills.

Review: Easy to setup - I found this monitor very easy to set up and configure. I have economy 7 but I only needed the single sensor as supplied. However, the software on the disc did not work (Windows 7). Go to the efergy website and download the latest software then there is no problem. But do make sure the date is correct on the monitor. This gives a good record of my usage over several time periods. After watching the real time energy consumption on the monitor, I think this will pay for itself very quickly in savings.
Review: Useful addition to the 'must have' box ! - Disturbed by ever rising energy prices, I decided to have a closer look at the electricity usage monitors available on the retail market - from which there are many to choose! The efergy E2 and the OWL wireless monitors , the type that sample total electricity outputting from the house electric meter, were picked to evaluate as both appeared to be claiming market leadership and both had similar favourable reviews. The display monitors of each are incidentally, remarkably similar in appearance The price for both was also similar, and for no particular reason I ordered the E2. This model is capable of downloading usage information to a computer software programme. The goods swiftly arrived from an desertcart supplier and the, plainly, good quality items were inspected and, using the set-up manual, quickly installed. This is a very simple procedure that takes barely a minute or so, after a manual pre-read through. The sensor is clipped around the identified cable exiting the electric meter and plugged into the small, eggcup sized transmitter. That's that and the duo can be left together by the side of the meter and within the meter box - if you have one. The transmitter will have been previously fitted with the appropriate AA batteries. With the display monitor to hand - also now fitted with AAA batteries - a small button on the back and a button on the transmitter are pressed - the manual instruction is quite clear on this. It is a rapid and simple procedure. The monitor should now show a steady `wireless' emblem and a small LED indicator should flash on the monitor and the transmitter at about six second intervals. That's it! Job done! The monitor can now be placed anywhere within range of the transmitter (about 40m) in the building, and will display data as wished. The manual is again clear on the various preferences one might wish to display. Does it work? Well, initially mind did then didn't! My house is a modern semi with the meter box on an outside wall. I was not over confident that a flawless initiation would be achieved and I was right! Within a short time the `wireless' emblem was flashing and a line of dashes had appeared where there should be figures. The manual says this situation indicates a loss of contact between the transmitter and the monitor. A further emblem was also flashing. It looked like a battery symbol. No mention in the manual of this - or indeed any other symbols, currently unknown that may at some time appear. However I rechecked the batteries and one in the transmitter had slipped from a tight fit in its slot. On correcting this all became well. The set-up is now working perfectly and by experiment have placed the monitor throughout the extremes of my house without loss of data. It is quite clear from observation that when, for example, an electric kettle is switched on, a 2kw increase in the displayed data is shown. Similar changes can be seen when switching on or off other appliances and lighting. This is a very intuitive piece of electronics and I hope when this `honeymoon' period is over I will not have become obsessed with forever closing down the house electric's system and living a life in semi darkness! The accuracy of the read-out data will not be of the quality of the official house electric meter but is still given as greater than ninety percent. At this level it will allow a reasonable check and comparison of usage against an electricity bill detail. It will activate a new energy awareness discipline I am sure and that is my prime aim. I haven't got round to using the software facility as yet - these are early days - but this promises to be interesting, when the historical data gathered by the monitor can be downloaded and displayed in various graphic forms. To conclude, this equipment will surely provide, for anyone, a more disciplined approach to energy use and will certainly appeal to gadget lovers or those who just love an analytical challenge! Pros: The components in the box appear well made and of good quality. Supplying Company has good reputation and a UK phone number! Reasonable cost. Simple to set up. Cons: No batteries supplied as standard. Instruction manuals okay but contain a few minor (non technical)errors and could be more comprehensive.

## Questions & Answers

**Q: What is the range of wireless monitor? Does it work through closed doors and walls?**
A: I have a large two storey modern house and have had few difficulties setting up my wireless monitor.  The receiver has worked pretty reliably throughout the whole house with the transmitter locked away in my utility cupboard downstairs and close to my front door. My only word of caution would be if you live in an older property with solid stone or brick wall, you may have reception problems but to-date I am happy with the device (other than the clunky software) and can recommend it.Purclewan.

**Q: We have a very thick cable going into the meter. Our owl monitor won't go around the cable. Would this one.**
A: You should be looking for the live cable 'exiting' from the meter not 'going into' the meter.  This is usually one of four cables exiting from the meter.  In my case all 4 cables are identical at approx 9mm thick and the E2 Classic would cope with a marginally larger cable say 10mm.  The instruction for E2 Classic indicate the live cable is usually the right hand cable facing the meter.  Hope this helps.

**Q: Can it monitor  3 phase or 1 phase?**
A: Hi. There is no information with the device concerning 3 phase. There is input for only one sensor so I presume the answer would be, no it is not suitable for 3 phase monitoring. I am not an experienced electrician so this is not a definitive answer but I hope it helps.

**Q: Can I connect the clamp to the incoming live feed before it reaches the electricity meter or must it be connected to the live feed exiting the meter?**
A: Hello there. It can be connected to either, as long as done safely. energymonitorworld..

### ⭐⭐⭐ Not for Mac users
*by M***N on 20 March 2016*

Hardware Installation The monitor and sensor were setup with ease following easy instructions. Had the monitor working very quickly indeed. Software install For a Mac it was pretty grim. Efergy have not registered the application with Apple so straight away users are faced with a warning that that this software maybe dangerous and requires an administrator security override in settings. Next it spawns multiple other application/ driver setups. Most Mac users have never had to install a driver do this is very odd indeed. Two driver installs and an install of Adobe Air you are required to reboot the computer. Most Mac users go months without rebooting, so this is odd too. Overall a great sense of unease is instilled by the Efergy eLink install. Monitor usage It worked well reporting realtime costs, energy usage and CO2 consumption. Additionally provided average usage for day week month. As a coffee table electricity monitor it does an adequate job. eLink Software The initial concerns were bourne out by the usage. It is an un Mac like app, it appears that the authors of this software have never seen a Mac OS X application. The design is confusing. On a Mac the magnifying symbol is used to indicate Search, but on this app it is resize the application. The usual three traffic lights in the top left of EVERY Mac app are absent here. So instead of pressing the Red traffic light to close the app as used in Every Mac app this instead requires rummaging around the application to find a button hidden away on one of the screens. Transferring data from the monitor to the Mac over the supplied USB cable was incredibly slow, took several minutes to collect a couple of hours of data. I dread to think how long it would take to download a few weeks worth of data, hours by the rate demonstrated. Overall the application is very pretty but largely alien yo any Mac user, navigating around using the unique design style employed requires significant effort and concentration. A great pity they did not follow all the standard Mac design rules and made it much much easier to use. Overall As a coffee electricity monitor, it is solid, competent device. But trying to do anything else using the Mac eLink software is very disappointing and with, more competent products available not worth it, so I have returned mine and purchased a competors. A great pity.
