I am a software engineer from the UK.
I live in the North-West of England, about 20 miles from Manchester &
Liverpool (that narrows the location down a bit :-).
I have a couple of projects on the go at the moment ( a robot and digital control of a model railway.) but am keeping an eye on Home Automation technology
with a view to my next project.
I work for Sun Microsystems.
Now back to the technical stuff. I found an old magazine article (circa 70's)
which describes a couple of cct's to allow remote control of appliance connected to HVAC over the power cabling. The big difference is that it uses Neutral & Earth for signalling. Given the known danger of an earth fault (would an ELCB or RCD be fast enough to protect the devices ?) has anyone any comments ?
