Light Scenes and Control Groups

Post by DAB LAD » Wed Jul 10, 2019 1:34 pm

When working on different Light Scenes in EVO.
Each light scene have its own independent number of control groups.
And each light scene would have its own documentation.
Adding a luminaire in a control group in a light scene and it would not be duplicated in the other light scene.

Now in reality, you design lighting into control groups within a space then design the dimming levels of each per light scene to achieve your desired effect per light scene.

So in EVO end up doing the design in one light scene only, then play with the dimming levels and check the values, then note it down, so when you finalize it you have to duplicate the light scene over and over, and put your dimming levels to have all your desired light scenes for documentation.

I would prefer EVO handle light scenes same as DX4. Same space, same control groups and as many light scenes as you want.

Hello DAB LAD,

Thank you for your feedback concerning the light scenes and control/luminaire groups in evo. You are right, the current implementation in evo is not great at all, but there is a common misunderstanding (especially from people that know Dx4): luminaire groups and control groups are not the same!
You cannot add luminaires to control groups in evo and all light scenes share the same control groups, exactly as in Dx4, but the control groups are calculated automatically by evo.

The idea is that you just model your light scenes. For example if you have one light scene "all on" you throw all luminaires in one luminaire (not control) group with 100% dim value. When you add another light scene with direct and indirect lights in different luminaire groups evo will take that into account during creation of the control groups (and other values like luminaire type, number of light outputs, RGB lights, dimming channels, controller type, etc.). You do not need to think about how to lay out the control groups to create n different light scenes and which luminaires need to be in the same control group to realize all n light scenes in evo. That is the reason why a new luminaire will not be added to other light scenes: A luminaire can be in different luminaire groups in different light scenes (but it cannot be in different control groups).

"Same space, same control groups and as many light scenes as you want." that is excactly as it is in evo.

The problem is that this is completely hidden from the users, that the documentation is lacking crucial information (like the mapping from luminaire group to control groups and which light fixtures are contained in the control group, ...) and that the concept is different from Dx4.

Best regards
Kolja

EVO presented luminaire groups the way you handle control groups. And working on light scenes you use your luminaire groups as control groups.

If EVO can implement that when you work on one light scene and add a luminaire to a control group(Luminaire group) and going back to other light scenes your changes are dittoed. Then you would not have any problem in documentation.

As it is now, you have to work on one light scene only and note down your dimming levels per control group and during documentation you would need to duplicate the light scene your are working on and apply your values. This so you can present all your light scenes in documentation with the same control groups.

In an actual implementation of a design, a control group is grouped together permanently(unless you reprogram in DALI) irregardless of a light scene.

Yes, I know this is how it is implemented in DALI etc and the concept in Dx4. However you need to figure out which luminaires should be grouped together in one control group, this can be a complex task in big projects, especially if you need to change something later on.

Yes, that would be possible but then again you would work on the control group level which is another approach. That is the way it is done in Dx4 or DALI.

The step of figuring out the control groups is done by evo automatically. The idea is that the lighting designer can concentrate on the task of illuminating the object and does not need to worry about DALI configuration and control groups. You tell the software which luminaires should be at which dimming level in which light scene and evo tells you which control groups you need and how to set them up for DALI. Or at least it should be like this. As I said in my previous post, the current implementation of the documentation has some issues that make it quite useless at the moment.

You just need to create the different light scenes with the groups of luminaires you wish to control together in this light scene (luminaire group), evo calculates the control groups which are the same in all light scenes. So it is possible to have all luminaires in one luminaire group in one light scene and to split them into five luminaire groups in another light scene and perhaps in two groups in a third light scene. That is the reason why a luminaire added to a luminaire group in one light scene is not added to the other light scenes, you can have completely different luminaire groups there and evo will not know to which luminaire group it should add the new luminaire.

A luminaire group in evo is not a control group in Dx4 or DALI but evo will calculate the control groups needed from the luminaire groups used in all light scenes.
