Efergy homeCO2meter Review

Read an REUK.co.uk review of Efergy's homeCO2meter electricity usage meter

This is a detailed review of the Efergy homeCO2meter (1) - a wireless device for measuring and tracking electricity usage in the home and office.

The Efergy meter is very similar in function to the Electrisave, so if you do not know anything about Electrisave please take the time to read our introduction to Electrisave (2) and Electrisave review (3) first.

Efergy homeCO2meter

Efergy in its packaging - display unit, sensor, wireless transmitter, and ball-point pen

The Efergy meter arrives in packaging clearly made from recycled (5) materials (see image above). Unlike the Electrisave, the Efergy meter is supplied batteries not included. Two AAA batteries are required for the display unit, and two more for the wireless transmitter/sensor .

In the instruction manual it is recommended that rechargeable batteries (6)* are used, however, the vast majority of people do not have rechargeable AAA batteries (7) and a charger and so will be forced to go out and purchase disposable batteries. It would be better if a pack of four green disposable batteries were included with the meter, or even a set of rechargeable batteries and a charger.

* Rechargeable batteries are not ideally suited to this sort of application since they have a rapid self discharge compared to disposables. This is why rechargeables should never be used in smoke alarms for example. If rechargeables are used with Efergy, expect to have to recharge on a monthly basis.

Installing and Configuring the Efergy Power Meter

Getting the Efergy meter up and running was very simple and took just two minutes from start to finish. The printed instruction manual is very clear, well laid out, and mercifully short.

Efergy sensor installed on the live output cable from the electricity meter

The image above shows the efergy sensor clipped onto the live cable of the electricity meter. With this sensor plugged into the wireless transmitter, it takes just one press of a button on the display unit to locate the sensor and to start displaying its readings. All that remains then is to to set the cost per unit (kWh) of electricity used, the time, the date.

As with the Electrisave, the cost per unit must be entered as a fixed amount despite the fact that many electricity companies (8) offer non-fixed tariffs - e.g. a different price for the first few hundred kWh per quarter, cheaper prices at night etc.
Read the Configuring the Electrisave paragraph of our Electrisave Review (9) to find out how calculate your average cost per unit.

Setting the time and date etc is very simple - no more complicated than setting a watch - and the instructions are very clear and easy to follow.

An alarm can be set to sound if the amount of electricity being used exceeds a user-selected value. For example, if this is switched on and set to 5kW then, if a kettle is turned on at the same time as a tumble drier, the alarm will sound.

Efergy Memory Functions

Efergy offers exactly the same functions as Electrisave* - it displays instantaneous electricity usage in kW, as cost per hour, or as Kg of CO2 emissions (10) . This on its own is hugely useful and led to our very strong recommendation of Electrisave as a product in our review of that product.
* Only Electrisave has a thermometer and humidity sensor.

However, Efergy does not stop there - it has memory. Therefore it can display details of total electricity usage for today, each of the previous six days, this calendar month and each of the previous 23 months, and for this year. This information is absolutely invaluable and enables you to keep close track of your electricity consumption day by day as it (hopefully) reduces. Navigating the memory functions with Efergy is very simple and intuitive using the buttons on the display unit.

An efergy-branded ballpoint pen (pictured above) made of recycled materials is included with the Efergy meter. Perhaps it is with this pen the Efergy user is supposed to transfer the collected data to a chart or spreadsheet.

Conclusions about Efergy

This is a fantastic product providing a deeper level of functions than Electrisave while retaining the simplicity of operation of that product. As an additional benefit, Efergy is a full Ł20-30 cheaper than Electrisave! The information produced by Efergy can be used to save far more than cost of the device within months by helping you reduce electricity consumption (11).
