E-meter, rs485 to T12-g3 automatic detection

[HvH]

I want to use Limit Export (set to 10KW) and need to feed the inverter with the KW's that go into the grid.

- If I can get an rs485 module for my Iskra AM550, after connecting it via rs485 to my inverter, will it be detected automatically on the inverter and in the foxess app?

- Is it possible to connect, without any harm, a wifi module into the same rs485a/b (home pc at night)
- Can I use telephone cable to make the connection.

Thanks
Henk
