AC controller cannot go in the same room with Smarter 2 controller and one Netatmo Radiator Valve

Hi, I just bought two AC controllers, and one of them is in the dining room. There I have already configured a Smarther2 BTicino thermostat that is connected with 7 valves, one in the same dining room.

Well, the Control app, does not allow me to put the AC controller in the dining room and wants me to create a new room. Apple HomeKit allows me to put it in the dining room, but then I have conflicts and I cannot move it in the Control app to the dining room. I have made many tries, the last one I deleted the  AC controller from the HomeKit and I installed it form Control, again I cannot put it in the dining room.

Can you help me with this? Shouldn't it be compatible also with the Smarther2 BTicino thermostat? I assumed that i could control the temperature in the same way I did before. At least,  the image in the  AC controller selling page suggested so.

Please let me know quick, because if it is not well compatible I'm still in time to return it.

Regards,

  Bernardo
