I'm (still) putting my home automation solution together, and my electrician, who will be running all the cables, has said that CBUS is easier to cable because it is daisy-chained, whereas at the moment in my design all my CAT5e cables come back to the switchboard (and then the Arduino), so each light switch will have it's own cable going back to the Arduino.
I like the sound of daisy chaining, it seems like a neater solution, but I honestly have no idea how to approach that. I think I need to put a small circuit behind each light switch (which is not a problem), just like the CBUS switches, the purpose of the circuit will be to uniquely identify that particular switch. And this would have to be flexible enough to accommodate up to 6 switches on the one wall switch (i.e. 6 gang). The small circuit would also need to be able to communicate, sending the status for each switch to the Arduino, so that the Arduino can then switch on / off the solid state relays as per the programming.
Any guidance / thoughts on this would be very welcome!
Thanks in advance ;-)
