Offical API found

Hi guys,

I found your Project while searching for a possibility to Control The Yamaha Music cast System in combination with my Smart Home implementation.
Very nice coding and excellent work!
I recently found the Official API on a Forum and like to Share it with You since You probably might be interested in it.
It also includes the necessary Http calls for linking devices together which might be very useful in this project as well:
Basic API: https://community-openhab-org.s3-eu-central-1.amazonaws.com/original/2X/9/931ea88e30cf0f05fcdee79816eb4d3f12dd4d70.pdf
Advanced API (eg linking devices): https://community-openhab-org.s3-eu-central-1.amazonaws.com/original/2X/f/f788d96dc1d4c3caaadd4eb1d87457c0b253d7f2.pdf

Thanks, that's interesting. I wasn't aware of a json api.

Should maybe even be possible to generate an api from the pdf

The "YamahaExtendedControl" HTTP API works with newer receivers 2016+ that support "Musiccast" and not with the rx-v775 etc. network receivers. I haven't found a definitive list of network receivers that use YXC. The rx-v series and contemporaries use an XML protocol for the internal web app and also the YNCA protocol on port 50000 which is used by the AV remote control app.
