I currently have latest version of venusOS running on Pi Zero 2W. I updated firwmare so wifi works, and I'm using direct cable to my 75/15 controller in my jeep. Local console works, and I'm connected to VRM just fine to get stats there.
What I would like to do, is be able to collect some of the metrics (volts/amps for solar/battery/load) from a script running on the RPI zero as well. Is there an API or SDK where I can get metrics locally from the RPI? As opposed to making api call to hosted VRM.
Ideally I'm looking for a command I can run from rpi zero 2w to get metrics that are sent to VRM.
