getScene returns null about yetanotherhueapi HOT 2 CLOSED

Hey, thanks for submitting an issue! Unfortunately that's not how scenes work. You recall one, it adjusts the affected lights -- and afterwards there's no way to know how the lights got to their current state. Even if it worked like you thought, relying on scenes still wouldn't be a good idea: what would the API even say as the scene of a room or a light, when a scene has been recalled, but some lights then adjusted manually?

I do sympathize with your confusion, the library kind of does lead you to believe it would work like that. 😞 Actually the getter method is there so you can read the settings you put into a scene yourself, when you are about to activate a scene. So the State object is kind of different depending on whether you created it or whether you got it from a Light or a Room, as the API does not populate all those values that you yourself can use.

All this being said, the solution to your problem should be to simply get the states of the lights in the room, not the scenes. 😃 Remember to enable caching (Hue#setCaching(true)) before you get the states of all the lights. That way it does not call the API ten times if there are ten lights in the room. Then, once you've stored the states, disable caching again. There's more on the subject of caching in README.md.

I will add Javadoc comments for the State#getScene() method clarifying the issue! Thank you and sorry again. 😅

Thank you very much for that explanation! Will continue to test and see how I'll solve this :)
