Connecting Multiplus-II, Cerbo GX, Pylontech batteries and a Fronius Primo

While trying to connect everything I realise I made a mistake on the first cable, so I'm trying to make sure I got everything right before returning the wrong cable and buying the right ones.

Cerbo-GX <--> Pylontech US2000C : I need a "VE.Can to CAN-bus BMS type A Cable 1.8m" from "BMS.Can" port to "A/CAN" port right?

Multiplus-II 5000 <--> Cerbo GX : I need a RJ-45 UTP cable right from MP's "VE.Bus" port to Cerbo's "VE.Can" port right ? Is this just a standard Ethernet cable?

Fronius Primo <--> Cerbo GX : I just need both device connected to the same network through their LAN ports? Is it enough if both devices are on the same WiFi network?

Thanks for the help !

Yes, it's a standard UTP/LAN/RJ45 cable.

But in Cerbo you plug it in a VE.Bus port, not in a VE.Can port.
