The e2 couldn’t really be much simpler to install. Simply put the clamp onto the live mains cable in your fuse-box and put the display on your coffee table! Then program the display for your own requirements and that’s it!

The savings vary from user to user but they can be considerable, we reckon up to 20%, if you use an efergy monitor and change the way you use the electrical appliances around your home. We have put a guide together to show you how small changes can make a big difference!

The sensor should fit loosely around your cable. Please do not pack it with anything to make it fit tighter. This could cause inaccurate readings and potentially be a safety hazard. If the sensor is too small for the cable you may need to purchase an XL sensor from our e-shop.

All our monitors show power information (kW), cost information (£), and carbon emissions (CO2). The information is displayed in three different modes: instant, history and average. Press the top Function Button to change the information displayed from one mode to another.

Both the transmitter and the receivers work with 1.5v alkaline batteries and in addition the monitors can be powered by 6v DC adaptor to save on the use of batteries.

Our transmitters use 433 MHZ to communicate with the display.

Our transmitters send energy information data every 10s/15s/20s.

Transmitters work up to around 328 Feet within the home. But this will depend upon the environment in which it is working. If the building that the monitor is operating in contains ironwork in the walls, thick concrete walls or floors and other wireless technology such as weather stations and wireless thermostats, then this can greatly reduce transmission ranges and possible cause the monitor to drop its link.

Really low, less than 0.001 kWh.

All our monitors can display electricity consumption with a sensitivity of 1W.

Independent testing carried out by Intertek ETL Labs found that in a typical utility environment efergy energy monitors were 97 -99% accurate when compared to a revenue grade meter.

The simples way to do this is to take your "Total electric bill amount" and divide by the "Total kWh consumed". This will give you a value of for example, $0.09 (equals 9 centsper kWh). This will give you a cost per kWh including ALL charges, which is what you see on your total electric bill. For setting Time-of-Use periods refer to the Manual.

Our monitors can record data for the last 7 days, 7 weeks and 24 months (12 months for the elite monitor). They can also store hourly information for the last 240 days.

All information is stored in an internal memory which saves and holds the data even in case of power cut, or when you remove the batteries. In the event of a power cut the clock and the date will remain the same than when the power was removed. You will only loose the information stored in the memory when you reset the device.

If you need to change or remove the batteries, the display has an internal memory, so information stored on the display will not be lost.

Battery life depends upon the quality and condition of batteries used, time spent interrogating the collected data and the intervals between transmissions. In ideal conditions up to 18 months of battery life can be expected in the products.

Only your energy provider can supply these details. Please review your last bill or contact your provider.

Move the display closer to the transmitter and press the Link Button. If the dashes remain on the display this would indicate the transmitter and receiver are not communicating. Please contact efergy Customer Service to help locate the problem.

No. The backlight is on a timer to save battery life. The display should work at darker periods of the day, when any buttons are pressed. The LED backlight will be activated from 18:00Hrs to 6:00Hrs.

Only when is in the 'Energy Now' screen, push and hold for two seconds the buttons 'History' and Mode/Set until CLR appears on the screen. This will turn the display to his original setup (from factory) and should not affect neither time or date. Attention! You will lose all the information stored in the memory of the display.

The elink 2.0 brings a completely renewed look based in a cool blue colour background. The software includes three new interesting features:

• Historical and average demand curves: users can investigate daily historical as well as average daily (per week day and per month) demand curves.
• Add stickie feature: users can add text messages to every energy record. This will help track and follow up energy behavior in the home.
• Manage Demand Feature: the program shows the benefits of two possible shifts Tariff shift: it simulates the effect of moving from a single to dual tariff scheme, displaying the yearly benefits. Peak consumption shift: it simulates what would happen if demand peaks were to shift to off-peak periods (i.e. turning the tumble drier in an off-peak period), showing the yearly savings..

Before installing the software ensure you have the latest version of Adobe air, Java, and .NET framework. Once you get these install the software choosing “Run as Administrator”.

In case you want to reinstall the software, first uninstall any previous versions of the elink software and any folders related to it, then you can proceed to reinstall the software.

When running Windows Vista, make sure the User Access Control (UAC) feature is turned off before running this software. You must have Administrator privileges to proceed with the installation.

The elink 2.0 might not recognise the monitor due to an installation failure. Please try again or reinstall the software.

Yes, you can. You just need to select Energy Report on the left-hand side of the elink window. Next select your dates to include in the report. Then click next. From the new screen you will be able to select save to computer which will create an excel and pdf file or you can select email report. Note that when you download daily report the information is stored in an hourly basis (one value per hour), and when you download the monthly report the information is stored on a daily basis (one value per day).

When an USB enabled efergy monitor is connected to the computer the USB icon (on the display) comes ON and stays ON for some time, while is collecting the data from the monitor, After some time of being connected the monitor will start showing the 'Energy Now' or 'Instant screen' and you won’t be able to collect data. The data has to be collected when the USB icon is being displayed

The efergy monitor cannot be left connected to the computer and collect data continuously. It has to be unplugged from the computer and reconnected to get new data. The device has to be disconnected and after 10-15 seconds should be reconnected back to computer to collect data.

No, you can’t. The backed up data from elink 1.0 cannot be transferred to elink 2.0 at the moment, as both programs are written in different programming language and the backed up data/ folders and their structure layouts are different.

Yes, you can download the Mac version of our software from our downloads section. Our elink 2.0 Mac version is compatible with the latest Mac OS Snow Leopard.

elink 2.0 is compatible with Windows 7 (32 bit and 64 bit versions). Just ensure that the UAC is lowered to minimum, PC is restarted and the installation file is right clicked 'Run as Administrator' otherwise it won't link properly with the device.
