as Xmas present for a friend of mine i'm building a remote IR control for air condition based on nodemcu with temp sensor and, obviously, an IR led emitter.
Thanks to an under cover operation

The problem is that i don't have access to his remote for decoding the IR signals.
As far as you know, there are different IR protocols for samsung's AC?
They have already been decoded?
Thanks in advance for any help.
