Use Lm3 to control your Yamaha Receiver using HTTP commands ( RX- V671)

Maybe this?    I made this script to mute my receiver when i go out:

Code:

http = require("socket.http")
url_string = "http://192.168.0.43:80/YamahaRemoteControl/ctrl"

http.TIMEOUT = 5


value = event.getvalue()

if (value == false) then
post_request_body ='<?xml version="1.0" encoding="UTF-8"?><YAMAHA_AV cmd="PUT"><Main_Zone><Volume><Mute>Off</Mute></Volume></Main_Zone></YAMAHA_AV>'
elseif (value == true) then
post_request_body ='<?xml version="1.0" encoding="UTF-8"?><YAMAHA_AV cmd="PUT"><Main_Zone><Volume><Mute>On</Mute></Volume></Main_Zone></YAMAHA_AV>'
end

http.request(url_string, post_request_body)

Just change IP to your receiver and put the script in a event.

If someone is interested, I found out that more recent Yamaha receivers use this protocol; https://www.sdu.se/pub/yamaha/yamaha-ync...otocol.pdf
TCPIP port should be 50000
A power on command would look like this:

Code:

post_request_body ='<?xml version="1.0" encoding="UTF-8"?><YAMAHA_AV cmd="PUT">@MAIN:PWR=On\r\n</YAMAHA_AV>'
