Thanks for helping out @CraigWeb @phildunlap @Jared-Wiltshire ,

I couldn't get it to work with a Persistent TCP data on central server, so set up on an ES on Site and it seems to be tracking good. All the 4's and 1's are lining up where I expect them.

Thanks Again.

I got this to work:

var prevVal = p709.lastValue(2);
var thisVal = p709.lastValue(1);
var nextVal = p709.lastValue();

if (thisVal >= prevVal && thisVal >= nextVal) {
    // peak
    return 4;
} else if (thisVal >= prevVal && thisVal < nextVal) {
    // still climbing
    return 3;
} else if (thisVal < prevVal && thisVal < nextVal) {
    // trough
    return 1;
} else {
    // falling
    return 2;
}

Hi Rowen,
Hope this helps to get started.

I am only monitoring current on one of the 3 phases on a small job, and I've used:

return (1.732 * 0.7 * p217.value * p218.value)/1000;

1.732 = Square Root of 3
0.7 = power factor I measured onsite once
p217 = Amps
p218 = Voltage

It's not going to be as good as a power meter, but gets me trending which is all I am after and it's fairly close.
