Re: HA without fallback-CBUS

["Martin McCreesh" <martin@xxxxxxxxxxxx>]

I've been looking a half way approach for a cbus install later this year.
Planning to put override switches for main lights at 2 key locations in the
house. These locations will be CBUS nodes anyway.  One issue that maybe
somebody can help with is what happens if you apply full power to a cbus
dimmed circuit - could it damage the CBUS dimmer.  The alternative requires
a good bit of extra cabling and invloves using a two way switch to isolate
the feed to the light from CBUS.

Depends what you mean by a fallback. My Idratek
install<http://www.automatedhome.co.uk/modules.php?name=Forums&file=viewtopic&t=746>is
designed to be i) removable in case of sale and ii) tolerant to
control
computer failure due to Reflex (built-in) functionality. If there's no
power
to the HA network, there's probably nothing to switch !

I know of another Idratek install which has put the panel relays in
parallel
with existing switching, which might be the kind of fallback you were
thinking of. I guess that you could do something similar with the other
systems (C-Bus etc) out there.

But really, anyone would think you can't trust this technology stuff ...
