RE: Re: cbus zone/scene confusion

[Paul Gale <groups2@xxxxxxxxxxxxxxxx>]

That's one of the big advantages I've found using HomeVision and one
of Kevin's CB/HV/xAP gateways - it allows some incredibly flexible and
'intelligent' scene handling etc - I haven't needed to use the CB inbuilt
scene functions really. I just create a virtual 'group' on the CB network
and when that's switched, HV recognises this and does it's stuff - e.g.
setting a number of CB lights and closing curtains, switching AV kit etc.
Very powerful :)

Paul.

Ah yes, good point, I'd forgotten that the area was applied at the module
level... - Personally I do use the Area function, but I keep it fairly
simple & only use 2 areas: Upstairs & downstairs, which I use to
switch loads based on whether I'm arming Comfort to Away mode or to Night
mode...

Just to mention... you wont be able to place a specific C-Bus 'group' in
an 'area' .    A physical output unit like an 8 channel dimmer or a 12
channel relay can be assigned an area but not each channel independently
.    If all your kitchen lights were on channels off one such unit then
this would be usable for say 'kitchen' .   I think this was an early
feature of C-Bus that has remained but is not longer encouraged.

Scenes are definitely the way to go and work very well ,  They're clever in
that you can divide scenes across several units (which helps if you hit
memory issues) and the indicators on buttons that set scenes light up when
the scene is 'valid' ie all groups are at the correct level.

A scene is 'activated' when a specific C-Bus group is set to a specific
level and this can either be a lighting group or a trigger group.
Trigger groups are just a way of separating the 'trigger'  functionality
onto a different and specific C-Bus application , which improves clarity
and is sometimes necessary when you interact with other C-Bus applications
aside from lighting.

Thinking of 'zones' might add to confusion in how you visualise things on
C-Bus as this doesn't really exist within the lighting application ,
but does exist in the HVAC (heating) application.     I think from how
your using the term zones  that  they are really scenes on C-Bus.
