Re: CBUS assistance

[Kevin Hawkins <lists@xxxxxxxxxxxxxxxxx>]

Chris - do you get accurate indicator lamp operation with scenes , and
if so where are your scenes held ?  I am seeing real weirdness here
which I keep putting down to the 'in progress' C-Bus code I am writing
on the trigger application. This happens particularly where I have
individual keys for say two lamps and those two lamps are also part of a
scene on the same switch  (all these three keys using the trigger
application via a Neo - not groups and not on the switch itself as it
isn't scene capable) .  The indicator lamps just don't reflect current
state and the multiple member scene light is always on even if the scene
is broken.. A setup slightly similar to the one Adrian is trying
although he is I think using 'logic groups' on the dimmer which I
haven't tried and I believe is being deprecated.

scenes to get this to work. I am only used to DLT's on which this is quite
possible as you describe but you would not define a new group to do it. I
have observed that you can get some weird behavour on cbus - it seems to
have memory. If a switch thinks something is off but you turned it on on
the dimmer itself for example a single push of the switch would not turn it
off. You would need to press it twice to get the desired effect. You can
get stuff like this after power cuts until the state all gets itself sorted
out.
