I’m querying PV inverters using the SunSpec binding and wonder how to retrieve values such as home consumption or grid feed that originate from an inverter-(RS485-)connected smart meter.
Some inverters that come bundled with a smart meter from the same vendor have proprietary modbus registers for this but I’m looking to implement this for the generic case using SunSpec.
Can I create a smart meter sunspec binding thing and point it to the modbus TCP/IP bridge of the inverter ? Or would I need a separate interfac into the meter ?
Has anyone gotten this to work?
Thanks for any enlightenment of mine.
