649RE: [ukusa_gateway] DLT and Saturn Scenes in the Gateway
- Nov 23, 2012
Thanks for this Kevin.
I’ve read up on triggering, though not sure I understand it entirely yet.
I see that Triggering uses a different application (202 as far as I can tell), so does this mean I set up a light with 202 as ‘extra data’ in HV? If so, how do I get the gateway to send the correct trigger for each scene? I guess it’s made up of the group address somehow, but also needs something to reference the scene number in the DLT or Saturn switch. Is there something which documents this?
The gateway doesn't effectively care or know about scenes. It tracks
and controls the 256 groups within the lighting (56) application. It
can additionally control groups on other C-Bus applications that use the
same lighting protocol but it doesn't tracks their states. So you
can happily use C-Bus native scenes.
Scenes are just a collection of group states that are triggered by
'something' and that is normally a group on the trigger application
being set to a specific level (action). The scenes are stored somewhere
else on the C-Bus network typically in a scene capable light switch or a
touchscreen / Wiser. Larger scenes can be spread across multiple devices.
HV can issue these trigger commands via the getaway as can a button on
a C-Bus switch. The gateway however doesn't report the changes on the
trigger application but it does of course report the resulting lighting
group changes. There is no reason you have to use the trigger
application to invoke the scene although it is tidier as that is it's
role. You could trigger scenes from lighting group changes should you

So setting up pseudo 'scenes' in HV will likely run into buffer overflow situations. Therefore I wanted to know if the Gateway does currently support scenes programmed onto Saturn and DLT switches. I've looked at the documentation I have and also old messages in this forum, but can't see anything specific, but sorry if this is a repeat question.
