As compared to other eco-friendly technology, after testing the Wattson energy Monitor has come across as being a lot more sophisticated. The Wattson Energy Monitor measures your household energy consumption in real time in either pounds or wattage and setting it up is very easy.
As with all wireless electricity monitors the Wattson has an electricity detecting device which is clipped onto the mains supply cable where it enters your electricity meter and you then place the well-designed unit in your house and instantly see how much wattage you are using along with the cost in pounds.
To use this nifty eco-saving gadget, simply clip on its sensor clip to one of the mains cables leading to your fuse box. The Wattson will then display the data into watts or, more importantly, in monetary terms on its LED display.
The Wattson also has some party lights underneath the unit, which will change color depending on whether you’re using less electricity than you normally do, or if you need to turn down the heating a bit more.As you move around the house switching off gadgets, the light colors will alter until most things are off and you get a cool blue glow.
For ease of use the Wattson is wireless, so you can carry it anywhere in the house within a 30m radius.But what about the electricity used by this gadget itself? Well fear not as the transmitter uses a rechargeable battery which only eats an average of 5 watts of power.
According to the guys at iWoot, to put that into perspective, a kettle can use up to 3000 watts just making a cup of tea.Therefore, when the kettle is on, Wattson will display £3,000 which is the amount it would cost if the kettle were left on for a whole year. Because of its futuristic design the Wattson is also a fascinating addition as a focal point and conversation piece especially when the lights move from blue to red as consumption increases
The big difference between the Wattson and the other monitors we have reviewed is that you can download and analyses your consumption through its Holmes software (see graph below). On the downside it uses a mains adaptor and although the quick set up instructions are easy to follow you will need to download the Holmes (Software to download data for graphs and trends) PDF to understand how to use the data.
