Re: Power line communication
I tried several plc modules, from different years so certainly with different ic inside, and they all have the same default.
if you plug it in a slot it works, if you plug it in the next wall slot, it does not work... it is not reliable
you have to be on the same portion of the grid, no counter between of it does not work throught.
and this is in the same house, really below the 100 meters of cable...
sorry plc is not reliable for me.
ethernet or rs485 are.
and may be wireless network, some technologies allow long distances, I think I read somewhere fireworks makers use such technolgies outdoors.
