I was not happy with the generic IR codes supplied for my Denon AVR. So I created my own IR code file for bulk import based on Pronto codes. I will use this until the native IP integration is available.
I have a Denon too, and i use home assistant integration. It works but sometimes slow to respond.
Denon native integration will release soon normaly 
Hello,
is there a database for exiting IR datasets or where I can upload my own to help building a big database ?

Can’t you use network control ?
I would also prefer network control. But this doesn’t seem to be supported yet. I especially need this for my LG television because the IR receiver only receives at a very narrow angle. It is not enough for the IR transmitter to transmit from the side.
Fair enough, I’m doing things through home assistant so have more options for control.
