Pioneer AVR control over IP tip

[zaphod]

I just found something out that I will post here as it isn't well documented.  This should work on Pioneer AVRs made over the last decade that have IP control.  My Pioneer Amp is from something like 2012-3.  There is a fair bit of documentation on the web about how to control Pioneer AVRs that is generally done with Telnet.  But they also have a REST API, but there is very little documentation beyond this github page:  https://github.com/rwifall/pioneer-receiver-notes .  There are lots of web pages out there with info on the codes to be used by telnet, and these codes can be converted to HTTP GET commands.

Long story short: You can control your amp with HTTP GET commands like this http://<AVR IP Address>/EventHandler.asp?WebToHostItem=1HA (this command has HDMI audio being passed through rather than processed by the amp)

Why is this useful?  You may have a need to do some esoteric control of your amp that is not part of the basic driver. Using that code with an HTTP GET from the generic TCP driver will allow you to do stuff that it isn't easy to do today.  Like changing the Amp's video output resolution, or dimming the display on the front of the amp.
