Annual Daylighting "matrix receiver error"

I carried out an Annual Daylight Autonomy on a model with multiple rooms.
I used the room from solid method, applied the Solve Adjacency command and Radiance multipliers to room faces.
Simulations seem to work properly.
But this message:
C:\Program Files\ladybug_tools\python\lib\site-packages\honeybee_radiance_folder\ UserWarning: Room_2 sensor grid has no view matrix receiver. It will not be included in three or five phase studies.

appears when simulation run, for all rooms.
I attached both model and simulation file.
Could you please tell me if I have to worry about it and if I made any mistakes?
In addition, I would like to ask you if, with this method, there is any chance to change room label and how to do it.

Thanks in advance for your help and availability

Hi @FrancescoEmanuele,

You do not have to worry about the warning.

You can change the room names when creating the rooms with HB Room from Solid. You just have to add a list of names equal to the length of the number of rooms.

Thanks Mikkel,
I have more solids connected to same “hb room solid” , 15 rooms to be precise ( I then used solve adjaciency ).
If I add a list of room names like:
Stanza 1
Stanza 2
Every room will have all names (instead of just one…)
Could you help me in solving that?
Thanks in advance
