I purchased 10 of these from the UK and I have 6 left.
I did not know that my large black monitors were able to be changes to individual circuits and not just 1 cable for each monitor.
So by adding the extra cable/Clamps, I now am additionally monitoring the power usage on my Oven, HotPlates, Air Conditioning, Power Points, Lights - basically anything that could be separated/Identified/Grouped in my electricity box. These all are sent to the energomonitor website then.
I have 6 spare cables if anyone wants them - not trying to make any money out of this, just trying to recover some costs.
