Look for "Web Control function" in the Owner's manual Table of Contents as noted below in the USA manual.

 

I know how to access the web interface; I just can't find a way to set volume there. After searching even more, I'm pretty sure it's not possible. The interface only provides access to Settings, which doesn't include current volume.

But actually I solved my problem another way. I'll share the details in case it helps anyone in the future.

There are actually (at least) two HTTP interfaces to the newer Denon/Marantz receivers. The official web control interface is provided over HTTPS in port 10443. That's the one that is visual but only provides limited access to settings; it does not offer full control. You can use GET requests to trigger actions that are provided here, but it's not ideal and I wouldn't recommend it.

The full REST API Is provided on HTTP port 8080 and you can do basically anything with this format:

http://{IP}:8080/goform/formiPhoneAppDirect.xml?{COMMAND}

The commands can be anything listed in the Denon IP command chart. Here are some examples:

Change to Game input
http://{IP}:8080/goform/formiPhoneAppDirect.xml?SIGAME

Change to Media player input
http://{IP}:8080/goform/formiPhoneAppDirect.xml?SIMPLAY

Turn volume up
http://{IP}:8080/goform/formiPhoneAppDirect.xml?MVUP

Set volume to 50
http://{IP}:8080/goform/formiPhoneAppDirect.xml?MV50

Get info
http://{IP}:8080/goform/Deviceinfo.xml

Get more targeted info
http://{IP}:8080/goform/formMainZone_MainZoneXmlStatusLite.xml

Hope this helps someone in the future with the same problem!

 

Thank you for this! It's exactly what I need. I might make myself a quick python controller app even... Hmm..

I managed to find your post while googling to find a solution to control my marantz avr receiver from my pc. And I'm making sure to include those words to help the SEO and hopefully lead others here

Edit: You could even use this to make a standalone touchscreen wifi remote with a single board computer like a raspberry pi! Then you don't need to worry about line of sight to the receiver, and you don't have to interact with your phone!

 

I'm curious. Is anyone else using this smartthings web request multi master? I cannot seem to get it to work. I know it's my suntax any typing the commands in correctly. If anyone wishes to help I can explain in more detail

 

Anyone know where the more modern amps (just upgraded to 7015 from a 7007) keep the album art images? On the 7007 I could access the web art at {ip}/NetAudio/art.asp-jpg and pop it onto a display on the wall... I can't find it anywhere on the 7015 and haven't been able to get the Spotify API to play nice yet...
