The A/D converters on a SiteMonitor only do DC. You would have to rectify the current going through the shunt, and then bias the measurement to accommodate the difference.

I know Forrest has got the DC shunts, but I don't think he has anything for AC or Clamp on.
The Iotawatt looks interesting. How hard was it to setup? Do you just create a cloud account and it automagically sends everything there?

While it does not support snmp they may work https://iotawatt.com/# I use it with infuxdb and home assistant. It will support up to 14 ct clamps.

Since the Demise of the UBNT MFI, what's out there for easy current
monitoring for AC Circuits. Drop some clamps on wires at the panel and
read them via SNMP.
I have an Accuenergy device on the Mains of the panel, but their
products seem to be more for mains applications, not individual
circuits. I don't really even care about voltage or power or metering.
Really what I want to see is how often my Aircon unit cycles on and
off. The unit isn't smart enough to tell me how often it runs, and it
doesn't make enough extra load on the mains meter to see it above the
normal draw. So I want to clamp a set of meters right on that circuit
so I can see when it cycles the compressor on and off.
I'm still using MFI on another system, and it's still plugging away and
giving me good data. So if UBNT was able to do it, I'm guessing someone
else can do it on the cheap too.
