The Claim?
The E2 is a comprehensive energy monitor, with a whole range of functions that let you better monitor your energy use. It boasts a high wireless range and lots of display options so that you can choose exactly how you wish to view your data and you can even upload the data to your computer for storage and detailed viewing.
How does it work?
The E2 Classic 2.0 follows the same style as many energy monitors. A sensor is placed next to your electricity meter, and the data this collects is wirelessly transmitted in real time to a small gadget that you can view the consumption on. This model however, has a range of additional functions: a range of up to 70 meters from the sensor, viewing in KWh, cost (with a range of 5 currencies) or CO2, historical data stored for months and software that lets you upload the data to a pc or mac and view the data in a number of forms.
How did it work for me?
This really is supposed to be one of the most comprehensive energy monitors out there. So it is great to be able to put it to the test. The installation is fairly straight forward and the interface looks fairly similar to other energy monitors, but it was pretty cool to be able to switch between the different outputs.
Where this gadget really comes alive however is when you upload the data to your computer. You can view all your data stretching back to when you first switched it on, in a number of innovative graphs and charts. It really brings the raw numbers to life and lets you get to grips with where you really use your energy.
There is also an alarm function on the device that lets you set targets for your energy use. When you go over the limit, the alarm will sound. It’s the sort of thing you can use to try and challenge yourself to use less.
So how well does it work? It seems to be a pretty reliable monitor, and I would certainly take this over some of the cheaper monitors, which lack accuracy and reliability. It also boasts a better than 90% accuracy, which is fairly good for a monitor like this, considering that measurements are indirect, unlike the electricity meter, which takes a direct measurement. It’s certainly good enough to get a really good picture of your energy use.
I have one of these myself and its definitely made me more aware of how much electricity im using, its great!
I had an assessment from Mr bouquet, he suggested this product as one of the ways to save me money. It really is useful to actually see the amount of energy I use on a daily basis. very useful product!
