This approach interests me. I gather then that you run the Arduinos
locally in each room/area with sensors attached to these and then use
Zigbee and/or ethernet to connect the Arduinos back to your Linux server.
What software are you running on the Linux server?
For that matter, what software are you running on the Arduinos? :-)
Running wires etc is all old hat. I had not thought about electrically
isolating various areas and to be honest, I'm not even sure what that means.
To do true isolation I would need to run 1:1 transformers or equivalent
devices. I'm sure the comments here do not espouse that even if that
would truly isolate areas from each other.
Unfortunately, WAF needs to be factored in. She's not really into
tinkering as much as I. :-) And I to no longer have as much free time
for this as I used to. :-(
I can't see why I can't run a commercial protocol and/or my own
protocols alongside each other. It all appears to be Ethernet-based
these days.

As of late I've been playing with sensors and control here. I've been using
Arduino boards for input/output and Zigbee wireless or ethernet as
communication back to a Linux server for smarts.
Using various devices such as PIR/temperature/current/switches as sensors and
this morning I've received some solid state relays to do some switching of
mains devices. Still very much in the tinkering phase.
I also looked at CBUS, KNX and the ELK M1 briefly but like you wanted something
more open and also like to do things myself.
