I am running the Pi with a BMV & MPPT - is it possible to use the Victron AC Current Sensors with the Raspberry Pi to measure as "AC Input" and/or "AC Loads" or is this only possible by using something like a Multiplus? I think at a minimum it would require some way of getting AC current to USB or some pin on the Pi?
I've seen posts where people have figured out how to use analog temp/tank sensors, but what about AC Load/Input?
Not sure if you can use these or not:

Like nebulight said, you can use Carlo Gavazzi energy meters:

And a RS485-USB dongle:

These meters would show up on the device list page and you can view the data but their data is not much use to the system without a MultiPlus / Quattro. I'm not sure if any of their data directly shows up on VRM either, I only see the data on VRM as part of the system.
This is on a travel trailer install...Looking to use it as a grid meter to measure/monitor/log in VRM the Shore Power/Genset 120vac consumption... would like to know how much the Air Con/etc are pulling from the grid. But they are upstream of all the Victron gear I've got. and dont have something like a Multiplus installed.. Think it would work for that?
I have had success getting ac current value into pi using the following components:
CR Magnetics CR9580 series current sensor. 0-5 VDC output proportional to AC current
Adafruit ADS1115 ADC analog - digital good tutorials for getting it setup.
My setup logs solar production and use.
Hope this is of some help.
