Hi Xiaomi,

I have 20 devices Xiaomi in my house, all is best devices but only IR Remote I can't pair it with my air conditioner and Samsung Sound bar (but I can manual pair it by learning feature).
- I can pair with Panasonic Air Conditioner CU/CS-PU9UKH-8 (9000BTU), but
- I can not pair with Panasonic Air Conditioner CU/CS-PU18UKH-8 (18000BTU) and I can not use learning feature
- I can not pair with Samsung SoundBar HW-M360 but I can manual pair it by learning feature

Could you please help me to know why?
