Marantz (with Heos) Web API Flow

README.md

I am using this flow with a Marantz SR5014 Receiver with built-in Heos. Out of all receivers I have used in the past this one has by far the worst understandable API possibilities and I wasn't able to find much official info on the topic. It's almost like they don't want you to use it. :)

The more elegant and powerful solution is to use a telnet connection. I failed at that attempt and the existing denon&marantz modules didn't work for me, but my requirements are also very basic and the Web Interface solves just that. It allows to catch a basic status, switch the device on and off, select the source and set the volume.

Also I am not a programmer, just a guy trying to solve a problem. :) I am not experiencing any issues with the flow, but I guess it's not perfect, so please feel free to alter and improve this flow for yourself. To configure just open the config node and enter your variables. You can also rename the source buttons in there and set a standard source and a standard volume.

Hello,
Thanks for this flow! I am trying to use it with my Marantz SR 7013.
Your flow appears to work great, apart from the power on and off which just restarts the Marantz.
I also get this debug message after your power function node :
TypeError: Cannot read properties of null (reading 'hasOwnProperty')
If you are still using your code, is it still working for you? Many thanks.
