Two separate SE Inverters not possible over ModBusProxy

[Stony111]

Describe the bug

System architecture is like follow described:

• SE Inverter 1 with Meter and Battery on IP-Adress 192.168.0.1 - Port 1502 (for example)
• SE Inverter 2 (no Meter no Battery) on IP-Adress 192.168.0.2 - Port 1502 (for example)
• Both Inverters NOT connected together via RS485 - both runs complete separate
• ModbusProxy, which manage both IP-Adresses; IP-Adress of ModBusProxy Instance 192.168.0.3 (for example)
  ++ Inverter 1 is listen on port 2502 on this proxy
  ++ Inverter 2 is listen on port 2503 on this proxy
• Home Assistant with this integration

When I now want to configure the second inverter, the IP-Adress is the same, as of Inverter 1, because it's always the IP-Adress of ModBusProxy-Instance 192.168.0.3 - but the Port would be different: 2502 for Inverter 1 and 2503 for Inverter 2.

When I want to save the new Hub Configuration an error appears: Inverter is already configured!
I think in this check only IP-Adress is validated not the combination of IP-Adress and Port

Expected behavior

Creating a complete new Hub Instance of a second standalone Inverter, when Connection to all Inverters are handled via ModBusProxy!

The integration currently uses the host or IP to determine duplicates, even if the port is different.

It's on the to-do list to update this

Thanks a lot for the fast info. Do you have a plan for when you would implement it? Just so I can judge whether it's worth waiting ;-)

I don't have an estimated time right now, but I would probably work on it after the non-sequential inverter ID changes.
