It is similar, but not quite I don't think.
As you say, moode normally runs on an RPi connected to a DAC. This will be my situation once I obtain a RPi. Then I was planning to install BubbleUPnP on the same RPi. Then I log into Qobuz via the UPnP server on RPi. This sorts the Qobuz UPnP source and renderer (they end up on the same device). The remaining part is the UPnP controller, and this is the part is not so clear to me. There are various apps which will work for sure. What I was hoping to do is avoid using a dedicated UPnP controller app, but use the native moode web UI. After reading around the internet I see conflicting articles (see below), but generally it seems like the answer is no.
moode as upnp controller and renderer:
If you have a UPnP audio source to use with moOde, you can set up this option rather conveniently. You’ll need to go to the audio configuration page, scroll to the UPnP/DLNA option, and switch the UPnP Media Browser to the “on” setting. You’ll need to click Set before scanning for the server.

moode as upnp renderer only:
Are you logging into Qobuz directly from mconnect on your phone? In that case, the mconnect app will be acting as both the upnp media server and controller.
