Modbus TCP and database connection over 1 ethernet port

[luke.penko]

Hey guys

I'm looking for some help.

I'm creating a new project with an ESP32:
I want to read all my systems at home (heating system, electricity meter, water meter, ...) via modbus tcp and than write it into my database via API. For the hardware I chose an ESP32. I don't want to use the wifi interface.
So can I do it with only 1 ethernet port? If I'm putting a switch infront would that work?

I appreciate your help
Thanks
