I get different HEX Code for IR Scan with differents remote
Hi, I've a RM Mini 3. When I active the Learn Accessory in homekit and press a button in the remote control (for example TV), i get the Hex Code. But when i try again for the same button, i get another different Hex Code. 

I try with different remote control and I get the same problem. 

I try with long press in the remote control with a shot press, I don't have no idea.

Can you help me? Some idea?

Thanks and best regards.
