Remote codes

Are there any known remote codes beyond what the remote itself generates? I’m especially looking for discrete on and off codes, which would make macro’s for my universal remote easier. Separate play and pause codes would also be really nice.

what kind of remote do you have?

seems like there are no real extra codes.

my harmony software shows no extra for power but does for play & pause but they both function identically.

It’s a JP1 based remote. I know many devices will recognize more than what the physical remote outputs. I was hoping somebody had found some.
