Great for monitoring energy usage Review by George

I use it for pretty much what it says on the box - monitor energy usage. I found it easy to set up and the batteries have so far lasted for over 13 months. I have not tried to use any of the advanced facilities, only the "Energy Now" mode to monitor power usage mainly to a heated greenhouse in case any of the heaters either fail or get stuck full on, and it also clearly shows when additional appliances switch on or off.

Great piece of equipment Review by D A - Porto

I am quite amazed at what this device is capable of doing. The diminutive case is very much 'Apple like' and not at all cheap looking. The installation is very easy and the monitor can be mounted in various ways or can easily be carried around. I have had no problem with signal strength and my transmitter is mounted inside a metal "switch box" ( I am in Portugal and have a three phase supply) and even so I can carry the monitor around my quite large garden and see how certain outside devices affect the power being taken.
It offers many facilities for collecting data and I can't see that anyone would want more information to be able to understand where they are using power but I guarantee some surprises and it is quite difficult to reduce the last 500 watts or so.
The software for logging the figures on to a PC, or in my case an iMac, gives a good clear display with clear menus and it is very easy to switch from one unit (power; cost; Day; Week, etc. etc.)
I had one slight misunderstanding of the instructions (entirely my mistake) and I telephoned their Sheffield Help Line and got immediate, friendly advice.
I don't care where this unit is made, the design and the implementation is superbly carried out and you have the huge advantage of accessible support.
I can't recommend it enough and at this price, everyone should have one. Well done Efergy (Posted on 30/05/2012)
