I finally got the codes I needed for the Yamaha. Except I can't find the code for Night Mode. It would be useful for the home automation. All the rest I either found or decoded with IR Tool with the Yamaha code pdf. Be aware that IR Tool 1.2 has a bug and it doesn't work with my model (HTR-5640 and probably most other Yamahas). I had to play guessing games to find out what was wrong and correct it. When I finish it I will post the IR code list for it.
