half-dead cm12

[Stephen <mail@xxxxxxx>]

Hello,

Last night I smelt the characteristic smell of hot cm12. I unplugged
it, thinking it was fried. However the active home software can still
communicate with it, it passes the test option. I also have an
appliance module in the next socket and that responds to codes from
the cm12, but all the other appliance modules do not. Could it be that
the cm12 is only outputting weak signals that travel to the local
socket but not any further? I thought it would work or it would not, I
am surprised it half works!

This happened once before (with a different cm12), although that time
it failed completely. I am clutching at straws here but all I can
think is that I plugged the vaccuum into the same socket (not the
cm12s built in socket). I imagine vacuums make a lot of electrical
noise. Would this noise on the line have damaged the cm12? Should I
put a filter on my vaccuum?

Thanks.
