I already have a plug-in unit which detects amps, Watts and Voltage. I have been looking at one of these http://www.maplin.co.uk/Module.aspx?ModuleNo=220934&&source=14&doy=4m3
But I would like something more permanent with LCD display etc next to the meter and connected to the mains itself. Do such devices exist or is the above the closest thing on the market.
Also, how accurate are they?
Thanks
