I want to use the IoTaWatt to monitor a solar array on the DC side. I think the best (safest) way to do this would be to buy some industrial amp/voltage meters which output 4-20ma signals, and then feed that to the IoTaWatt.
I’ve looked through the blog posts and the support forum, and while it is mentioned in e.g. temperature monitoring, it’s never addressed directly.
Can someone explain what the setup needs to be to wire up a 3.5mm jack with 4-20ma signals, and how it should be configured in the Setup page?
Backstory: I’m looking at a solar power setup with a hybrid inverter/battery management system. The batteries are charged internally to the inverter, so the AC output is not necessarily representative of the solar input at any particular time. I want to monitor solar coming in, AC coming out, AC consumption in my house, and grid export, all at the same time.
