Cant see my M2 air conditioner on my apple home app

I have m2 in my bedroom and m3 in the living room. Each hub is connected to an air conditioner.
The air conditioner in the living room which is connected to the m3 hub i can see and control from the apple home app but the air conditioner that is connected to the m2 in the bedroom i dont see
I tried connecting the m2 using the matter/apple home with no luck
What am I missing here?

Hi. What exactly do you mean by “no luck”? Did you receive an error message?
