Dali interface scenes - gjniewenhuijse - 20.10.2015
How to use scenes with the dali interface?
Is there a kind of "software scene" object?

You can create simple scenes by making a script that writes the required values one by one.

And saving a scene? Do you have a short example?

Short example which can be used for any kind of scenes, not only for DALI.
First, you have to define each scene via a Lua table where each item is a table with two items: group address and value. Each scene has a unique id which can be a number or a string.
callscene(id) sets all objects in given scene to their specified value. First it looks for a saved scene in storage and uses default values if storage is empty.
savescene(id) gets current values of all objects from given scene and saves the whole scene in storage.
Code:
scenes = {}
scenes[1] = {
{ '15/1/1', 50 },
{ '15/1/2', 75 },
{ '15/1/3', 90 },
}
function callscene(id)
local key, scene
key = 'scene_' .. id
scene = storage.get(key, scenes[ id ])
if type(scene) ~= 'table' then
alert('Scene ' .. id .. ' not found')
return
end
for _, item in ipairs(scene) do
grp.write(item[ 1 ], item[ 2 ])
end
end
function savescene(id)
local key, scene
scene = scenes[ id ]
if type(scene) ~= 'table' then
alert('Scene ' .. id .. ' not found')
return
end
for i, item in ipairs(scene) do
scene[ i ][ 2 ] = grp.getvalue(item[ 1 ])
end
key = 'scene_' .. id
storage.set(key, scene)
