RE: Re: cbus zone/scene confusion

["Brian Smith" <briview@xxxxxxxxxxxx>]

My CBUS system is still on paper so I have no hands on experience
here.
However, I cannot see why you would want to lose any control / flexibility
by grouping channels (unless current restrictions force you to use multiple
channels for what is effectively the same load).  The whole point of this
system for me is to allow for any combination of channels and levels.

Out of interest, where does the memory become an issue?  In the light
switch's ability to store 'complex' scenes?  What options are available to
overcome such limitations?

Thanks

Brian

Starting to get there.

So currently I have 10 zones in the kitchen. All wired into separate cbus
channels. So I have the individual control if and when needed.
I also seem to be able to 'group' those zones into further groups, that can
be controlled as one.

Using scenes seems to use lots of memory as well. I am trying to ensure I
dont run into issues later down the line.

I will also take a look at areas.

I have found this. Will be reading tonight -
