I understand Brian, I dont have a logger and didn't plan on buying one so what results I'll be able to collect are going to have to be good enough.
I do have a E-Station Voltage and Watt Meter that I bought early this year but haven't even taken it out of the box, would it's results be viable or of any use for this ?
