RE: cbus zone/scene confusion

[Paul Gordon <paul_gordon@xxxxxxxxxxx>]

I'm no expert... I too struggle to understand trigger group
functionality (I
*think* I understand the concept at a high-level!)

I would summarise groups as the lowest level of "controllable
unit" in CBUS,
- i.e. what you actually switch on & off to control loads as a single
entity.... so you *could* put all 10 of your kitchen loads into the same
single group if you wanted to, - so long as you understand that you would
then only ever be able to control all 10 loads as a single switchable
entity... - all 10 on, or all 10 off etc... - there would be no possibility
of individually switching (say) half of those loads separately... - I'm
guessing that probably isn't what you want, if, like in my case, you have
separate sets of lights such as ceiling downlighters, under-cupboard
lights,
accent lights, pantry lights, cooker hood lights and so on... I want to
retain the ability to control those sets of loads individually, and so they
are configured as separate CBUS groups.

Scenes are (IMHO) the "proper" way to then control all those
separate groups
as a single entity if & when you need to... think of it like a macro...
So
as you have done, a scene is then an ideal way to implement an all off
"macro" - note that there is another level at which you *could*
achieve the
same functionality, - there's also the concept of an "area" in
CBUS, - which
comes above the level of the group... If you put all 10 of your separate
channels in a single area (say called "Kitchen") you could then
address the
area as a whole to send commands to all channels that fall within it.. -
it's a bit like a "supergroup" if you like - or if that just
makes you think
of ABBA, then perhaps a nested group might be a better analogy...

Helpful?

I've never understood trigger groups really! Would be good to know how they
can be used.

(56 channels so far)

All

I am now upto 30 zones on cbus and all is working quite well.

There is still something I cannot get my head around. I have things working
but sure I have fudged it. I am totally confused about scenes, groups,
trigger groups.

I have about 10 zones in the kitchen. At the moment I create a scene with
all zones at zero % in order to issue an 'all off' command. Should I put
all
kitchen zones into a single group and turn all off that way.

Can anyone also simply explain how scenes etc work?

Thanks for any pointers

Ben
