I think I might put the light/device definitions in an array to make it easier to process. You might also want to think whether you might need a scene to cover more than a single zone - I would certainly want that.

But it all hinges on how you want to actually use the data. As mentioned elsewhere in the thread, it may be a lot more useful to have the array as an array-like object, particularly if you expect it to mainly be used by scene.

```auto
{
    "Getting Dressed": [
        {
            "lightingzone": "3F_Bedroom",
            "devices": [
                {
                    "name": "ceiling",
                    "value": "255",
                },
                {
                    "name": "floor",
                    "value": "255,255,255,255",
                },
                ...
            ],
            ...
        },
        ...
    ],
    ...
}

```

So you might want to map some of that out before committing to a schema.

To be worth putting into a node, you'd need to be sure that it would be easily usable by other people who are likely to have very different sets of data.
