Reading different units through same (master) inverter about solaredge_modbus HOT 4 CLOSED

I'm assuming from your description that the slave inverters are accessible simply by providing a different modbus address. Because I only have a single inverter I've never been able to test this. However, I've modified the parent logic to allow the unit parameter to be set even if a parent connection is provided. When instantiating a new inverter you will need to do the following:

  >>> inverter_1 = solaredge_modbus.Inverter(host="10.0.0.123", port=1502, unit=1)
  >>> inverter_2 = solaredge_modbus.Inverter(parent=inverter_1, unit=2)

I'd be interested to hear whether this works.

That was fast :) I also don't have this setup at my place, but your change is exactly what I meant. Don't know what you mean with 'by providing different modbus address' as the slave inverters don't have their own IP. I'm planning to change the home-assistant integration and use this lib as dependency iso using the raw modbusclient and own register parsing. Your sunspec implementation seems pretty complete 👍

I mean I'm curious whether providing a different unit is enough to get the registers of a slave inverter when using Modbus TCP.

Happy to hear you find it useful!

Should work. Have an open PR by a user who tested it. (binsentsu/home-assistant-solaredge-modbus#12)
