Simply press down on the Tab and lift the top part away and the battery cover simply unclips from the body of the transmitter Tranmitter Removal 1.1

It's that time again every couple of years when you need to think about changing the batteries in the Transmitter (not the display) which is where your meters are.


Your installer may not have warned you there is 2 x AA batteries inside the transmitter which don't require replacing very often but if you start to experience problems then think about battery life in the transmitter as these batteries last about 2-2.1/2 years depending on condition and battery quality 


If you find your display loses signal and you have to press the button to get it going again, this is due to battery life.

Each Eco-eye monitor uses a non-contact current transformer to measure the current passing through the wire(s) being monitored. It does not measure voltage. The current is sampled many times a second and the average of these readings is sent to the display every 4 seconds. The user can set the voltage from 90 to 255 volts and this is used to calculate the displayed kW and cost figures.

Basically, all Eco-eye monitors measure the amount of electricity a property is using in real time and shows actual usage and cost. The display acts as a prompt to use electricity more efficiently. Every Eco-eye monitor has a memory facility so you can recall historical usage to compare consumption over various time periods. Eco-eye monitors are tools designed to educate consumers to use electricity more responsibly. There is a choice of several monitors depending on your needs.

No, the Eco-eye sensor(s) simply clip(s) on to the outside of any positive cable – this is usually the one exiting your meter and so measures your entire usage. However, it could just as easily be the cable serving a particular area of your home or business. Smart PV is a little more involved in installing as it has three sensors, but this should not be a problem in most cases. NOTE: If you do have any concerns about the condition or suitability of your installation wiring, you should consult a qualified electrician or send us a picture to info@eco-eye.com 

In the event that several people in the same area all have an Eco-eye, the transmission frequency can easily be changed to avoid any potential problems.The default channel is 2, but any other number from 1 to 30 can be selected, provided both the transmitter and receiver are set to the same number. See the instructions page for more details. NOTE: IT IS ONLY NECESSARY TO CHANGE THE CHANNEL NUMBER IF YOUR UNIT IS COLLECTING DATA FROM ANOTHER ECO-EYE IN A NEIGHBOURING PROPERTY!

Yes, Eco-eye works well with ‘regular’ or rechargeable batteries but rechargeable batteries may not last as long as disposable ones. Regular batteries are included with every unit. Did you know that regular batteries can be recycled? See: http://www.recycle-more.co.uk/nav/page2405.aspx

Eco-eye can detect a single light bulb being switched on or off. Eco-eye is designed to measure the total usage and works best when the background load is in excess of 50 watts.

Anyone who wants to save money on their electricity bills would benefit from using an Eco-eye. The range has grown so there are different models available for different situations ranging from a simple to use basic unit to others that have computer connectivity or measure solar power. Please go to Products > Comparison Chart for more information.

All Eco-eye products are designed in the UK. Products for low volume orders are still made in our UK factory whilst production of units for worldwide high volume orders has been transferred to our own factory in the PRC. The combination of our team of very experienced in-house designers and our own factories means we can react to design changes and bespoke customer requirements very quickly. We are continuing to develop innovative new products to add to our range – details are posted on the website periodically.

Many modern properties have meters which are located outside. Do you know where the key to your meter housing is? It’s our guess that you don’t! During our research, we discovered that many householders have either lost or mislaid their key! So for your convenience, we have decided to provide you with a new key. This means that you can avoid any unnecessary frustrations and install eco-eye without delay

In ideal conditions, the range would be in the order of 50 metres but this is compromised depending on factors such as the number of walls and the construction materials in the path of the signal. It is very rare to find that the Eco-eye does not work perfectly in domestic properties, but we do offer a full money-back guarantee for sales within the UK should you find that there is any issue. You can purchase a 3-metre extension cable for the sensor which gives the option of installing the transmitter in a convenient place which provides the best radio reception. It is also useful if your meter location is difficult to access or you need to have the transmitter close to a power outlet socket in order to use the optional AC/DC adaptor.

Eco-eye transmits on the 433 MHz waveband. This will not cause interference with any other equipment used in your home and is way below the frequencies that might be considered to be dangerous ‘micro-waves’.

All Versions of Eco Eye can be set to any voltage from 90 – 255v.  Apart from SmartPV, £,$,€ or a currency symbol can be selected, making them usable in most countries throughout Europe and the rest of the world. if you need further information regarding this, contact us on info@eco-eye.com

Yes – Eco-eye can monitor any live cable. As an example, some blocks of flats have all the meters in one central area on the ground floor. in this situation you will usually have a supply cable coming into your individual flat feeding a fuse/distribution board, and it should be possible to clip the sensor onto that cable. it is also possible to clamp the sender unit onto the cable inside the fuse/distribution board, but this involves removing the front cover and we would always suggest you ask a competent electrician to do this.

Most Eco-eye electricity monitors are suitable for three phase supplies with the use of additional sensors. The Elite 100 and Elite 200 come with three sensors as standard and are used primarily in business premises and not in domestic situations. The exception is Smart PV which is only suitable for single phase usage.

No. If you change the batteries you will only lose the data which hasn’t yet been stored to EPROM, i.e. 1-day maximum.

Our default CO2 emissions factor we use reflects the UK Government published figures for Grid electricity. This figure can be modified by the user.

Yes -Extra display units are sold separately as Eco-eye Elite Solo, Mini Solo, Smart Solo and Smart PV solo Ideal if you wish to use extra display units elsewhere in the home or office. They all work with the existing transmitter and sensor provided in the original Elite, Mini or Smart systems and will show exactly the same information. These are available on the accessories page
