I'm hoping to use the Arduino to fully automate my home.
Mostly with Ethernet cabling for switches.
Where to place the relays:
Centralised, 1 or 2 central points so all electrical cabling comes to these points and wired to many relays.
Or separate relays placed at each "switch" point.
To me the centralised seems the better option but many seems to go with de-centralised.
Z Wave and others seems to be de centralised not that I intend to use Z wave.
Any thoughts, ideas, much appreciated.
