Very interesting. I was thinking it might be nice to have an Ethernet to PLC bridge module.
For instance: Olimex POE ESP32 which has a LAN8710A Ethernet chip on it, and Power over Ethernet.

If you'd hook that up to a QCA700X or a IS32CG5317 (Which at least I can purchase...) you'd have a module ...

I remember you have to set a DIP switch in order for it to respond to the other UDP commands.
Can you show us the full JSON response from 'report 1' and 'report 2'? (And leave out the serial number if you like)
