Matter Room set up

[Nezaemmy]

@SuGlider with Matter library to set up endpoints in different rooms is not possible; the possibility is to group them in one room if all endpoints are from the same node.

What is the Matter Environment that is used?
Grouping and Room is done in the Matter APP.
For instance, I have Amazon Alexa here.
Using the Alexa APP I can associate any Matter Device to a Room or Group them and associate an action to the group.

I'm using HOME app on iPhone; the endpoints connected to one node they can't be set up in different rooms; they are grouped in one room

It seems to be an Apple Home APP issue.
I have uploaded the Matter Conposed Lights example to a ESP32 and I can, using Alexa APP, define a different Room and different Group to each endpoint and also to the Main Root Node device that actually has no practical function.

Therefore, it seem that the Arduino Matter Library doesn't control it. It is controlled by the Matter Environment APP code instead.

I could also change the APP configuraion and group all endpoint in a single Room/Group after setting them initially apart.
I also could set a same endpoint to more than one group/room and command the same light using "turn on room1", "turn on kitchen" as well as "turn on light1"

Any combination or any sort of arrangement with rooms and groups is working fine.
I have added all the 3 lights to the same room1 (group) and I have just commanded Alexa saying "Alexa, turn on Room1" and it has turned on all 3 lights.
