I've been playing around with SunSpec after enabling modbus TCP on port 502.

I'm using the application here: https://github.com/volkszaehler/mbmd

Command: ./mbmd inspect -a skybox:502 -d SUNS:1


What should I do with all this data now? :)
 
Grrr, there are some undocumented sunspec models. That explains why I'm missing the PV information that is usually in the 8xx range.

64125: [<sunspec2.modbus.client.SunSpecModbusClientModel object at 0x7fccf6ab9fc0>],
64127: [<sunspec2.modbus.client.SunSpecModbusClientModel object at 0x7fccf6ab9ff0>],
64129: [<sunspec2.modbus.client.SunSpecModbusClientModel object at 0x7fccf6ab9f90>],
64131: [<sunspec2.modbus.client.SunSpecModbusClientModel object at 0x7fccf6ab9f60>],
64133: [<sunspec2.modbus.client.SunSpecModbusClientModel object at 0x7fccf6ab9e70>],
64135: [<sunspec2.modbus.client.SunSpecModbusClientModel object at 0x7fccf6ab9e40>]}
 
I added metering support in the mbmd app for the Skybox Inverter so now I get some basic readings:

mbmd has the ability to publish to MQTT so to put it all together, I have the following data:
