Eco Eye Review
Eco Eye Review
A product review of Eco-Eye Mini - a wireless electricity monitor
shopping | energy efficiency | carbon | general
In our article
Eco-Eye Energy Monitor we introduced the latest realtime
wireless electricity monitor under development. Now (mid-Feb 2008),
Eco-Eye is now on sale here in the UK.
We trialled
Eco-Eye Elite and
Eco-Eye Mini (corporate version) for one month, and so what follows are the results of our extensive research and testing.
For background on related products have a look at our articles on the Owl (Owl review), Efergy (Efergy review), and Wattson wireless electricity meters.
Installing Eco-Eye
As with all
wireless electricity monitors a small electricity detecting device is clipped onto the mains supply cable where is enters the electricity meter*. This is in turn plugged into a battery powered transmitter which sends data to the battery powered wireless receiver which displays the electricity usage information on its screen.
*
A meter box key is provided with Eco-Eye to allow easy instant access to outdoor electricity meters.
Initialising
Eco-Eye for first time use is very simple. The voltage is preset to
240V (for UK use), so just the current time and the cost per kWh (unit) of electricity are all that remain to be set. (Check your most recent
electricity bill to find out the amount you are paying per kWh).
30 channels (wireless transmitting frequencies) are available, however the default setting (CH-02) can be used as long as there are no other
Eco-Eyes within 30 metres of yours. It is also possible to change the currency displayed from the default
£ symbol to Euro or $, and the voltage to 110, 115, 230, or 240V.
Eco-Eye Functions
One of the major benefits of
Eco-Eye when compared to its competitor products is its simplicity of use. OWL and Efergy have quite
busy screens showing lots of information.
Eco-Eye on the other hand has a very clear and simple display which hides its depth of functions from the user except for when they are needed.
The display can be left in
kW mode showing the current amount of power (to two decimal places - e.g. 1.23kW) being used in
realtime. Alternatively, the cash cost of using that amount of power for one hour, one day, one week, one month, or one year can be displayed making it very easy to see how much
money can be saved by turning off the lights in a room, or simply by switching off appliances is
standby mode. Finally you can display the amount of
carbon emissions you would generate if you used the current amount of power for one month.
Eco-Eye Historical Data Memory
As with
Efergy,
Eco-Eye has
history functions which enable you to look back at your electricity usage. Six sets of
historical data are stored inside Eco-Eye and can be displayed quickly with just couple of button presses. They are as follows:
1) Total kWh of electricity used in each of the previous 32 hours.
2) Total cost of electricity used in each of the previous 32 hours.
3) Total cost of electricity used on each of the previous 32 days.
4) Total cost of electricity used in each of the previous 32 weeks.
5) Total cost of electricity used in each of the previous 32 months.
6) Total amount of
carbon emissions generated by electricity consumption during the previous 32 months.
For example, below are shown the results (manually copied from my
Eco-Eye Mini) for the total cost of the electricity I have used over each of the last five days:
-01 = yesterday,
-02 = the day before yesterday, and so on.
Accumulated Data
When first entering
history mode, the 'history' icon flashes. This tells you that you are viewing
Accumulated data.
This shows how much electricity you have used so far during the current time period - e.g. if you were in
cost per hour mode, Eco-Eye displays the total cost of electricity used
so far during the current hour. When a new hour starts, that value is reset to 0, and the previous hour's total gets stored in
history. Accumulated mode is available for all time periods (displaying total cost of electricity) and will also display accumulated hourly
kWh usage and monthly
carbon emissions.
You can also display the grand
total electricity used since the device was last reset. This makes it easy to see how much electricity your house used while you were away on holiday for example (just reset that memory before departure) much as the trip odometer on a car can be used to display the distance you have travelled on a car journey.
Changing Batteries and Long Term Memory
When the display/receiver batteries need replacing, the stored
history data are not lost - all that is lost are details of any consumption since midnight on the day the batteries were removed from the display/receiver. Therefore it is best to change batteries early in the morning to minimise the amount of data lost.
Eco-Eye Mini Special Features
One problem with
Efergy and
OWL is that they get through batteries quite quickly. This can be expensive and inconvenient, and also results in yet more batteries going into landfill.
Eco-Eye has been programmed to reduce its battery consumption to the minimum possible.
Instead of the receiver being on constantly (or for long periods) to receive data, it has a very accurate internal clock which enables it to turn on the receiver for just a few
milliseconds (thousands of a second) at the exact times it knows the transmitter will be transmitting data.
Eco-Eye and Eco Eye Mini
There will be two products in the initial range - the
Eco-Eye Elite with a large display/receiver unit (170x80mm)
and large screen, and the smaller
Eco-Eye Mini identical in function but with a smaller display/receiver (approx 80x75mm). The transmitter and receivers are both powered by 2 AA batteries (4 Duracell AA batteries are provided), but can be powered with
rechargeable batteries or plug-in mains adapters (available at
£4.99 each).
Connecting Eco-Eye to a Computer
Although the
Eco-Eye unit itself does not have a
USB connector to enable collected data to be downloaded, displayed, and analysed on a PC, a new product to be called
Wi-eye is being developed which will work with the existing Eco-Eye transmitter sending data wireless directly to a PC. When the PC is switched off, the Wi-eye will continue to collect incoming data ready to upload it when the PC is switched back on.
This is an excellent approach which means that the
Eco-Eye will remain simple and affordable for the majority of customers, but has the flexibility (with
Wi-eye) to create a very powerful
electricity usage monitoring and analysis system for those that want to pay extra for added features.
Overall Conclusions
Eco-Eye is an excellent product. It has the build quality of
OWL (formerly known as
Electrisave), more history functions than
Efergy, and uses its batteries efficiently. It is also very easy to install, initialise, and use, and as explained below is well priced. With the possibility of integration with
Wi-Eye, it will be able to transfer all collected data direclty to a
computer
in realtime - a feature which will be of great interest to many customers.
Jan 2009 Update - Note that since this review was published new
improved versions of the OWL and Efergy wireless energy monitors have been released:
OWL CM119, and
Efergy Elite.
Eco-Eye is designed and made here in the
United Kingdom
and uses 100% recycled (and recyleable) packaging.

Thank you SO MUCH for the review - very clear, simple and concise.
It has definitely helped me to make up my mind between the eco-eye and efergy - and I'm glad the eco-eye is UK made plus all the recycled/able plastics.

We would like to notify all our customers who have been very patiently awaiting the arrival of Wi-eye that it will be released a little later than we had originally anticipated.
Since Wi-eye’s initial conception, there have been important developments in the field of real time monitoring and computer interaction. That being the case, we are currently modifying Wi-eye’s software to account for these and to provide our customers with a solid product that has a more usable interface and which is universally adaptable in this fast moving market.
Therefore we have taken the decision to delay the launch until the improved Wi-eye has been Beta tested. Once we have feedback from this and are satisfied with the results, Wi-eye will be available for general release. We do hope you will bear with us and appreciate our reasons for this delay. We are confident that Wi-eye will be worth waiting for and will keep you updated.
