multiple power distribution boxes

[daniel45]

Hi all,

Thanks to join your forum.

I'm preparing a home installation based on HOME ASSISTANT using KC868 with rapsberry.

I need multiple power distribution boxes in different buildings based on :

One main power box ( with KC868)
3 remote connection power boxes. (with relays and analog input )

So, could you help me on which  communication hardware and protocol  I can use ? ( cables CAT 6 are dispached between each boxes.).

Hope my explaination are clear .

Great thanks

Daniel

all power box's controller connect with CAT5 network cable, connect to same router is ok.
main smart DB use by Server16 raspberry pi controller. other DBs use smart relay controller without server16.
