Yamaha MusicCast receivers doesn't provide desc.xml

[cadavre]

Component/platform:

media_player.yamaha

Description of problem:

I have Yamaha R-N602D. Device is being configured OK with all available functions operating well. Yet I'm receiving an error while trying to fetch desc.xml file on init, because it's simply... not there.

Traceback (if applicable):

Invalid XML returned for request http://192.168.1.33:80/YamahaRemoteControl/desc.xml: b''
Traceback (most recent call last):
  File "/srv/homeassistant/lib/python3.5/site-packages/rxv/rxv.py", line 101, in _discover_features
    self._desc_xml = ET.fromstring(desc_xml)
  File "/usr/lib/python3.5/xml/etree/ElementTree.py", line 1345, in XML
    return parser.close()
  File "<string>", line None
xml.etree.ElementTree.ParseError: no element found: line 1, column 0

Additional information:

If I try to visit http://192.168.1.33:80/YamahaRemoteControl/desc.xml via browser or API client – it gives me ERR_INVALID_RESPONSE with empty body. Looks simply like 404.

Yamaha MusicCast firmware version is 1.30 (released 2018-10-04).

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates.

Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment :+1:

Same problem here, but I can't get the Yamaha component to load at all. I saw in an unrelated forum (maybe smart things) that the newer Musiccast devices required an updated URL; sounds like this needs to be updated in media_player.yamaha

I'm seeing the same issue. I'm using the yamaha_musiccast component though. All the controls work for me, but I'm seeing this error when setting up the component.

I have home assistant 0.88.2 via hass.io on raspberry pi 2b.

EDIT: Oh I see what's happening in my case. I was curious why the error mentions media_player/yamaha.py when in fact I have yamaha_musiccast set up. So I removed my definition and I still get the error. So it seems discovery tries to set up my Yamaha R-N402D as yamaha, but that doesn't work. My manual yamaha_musiccast setup does work.

@robbiet480 this actually is about integration:yamaha_musiccast.

Ok, I made some digging and this is what I've found:

• I have configured 'yamaha_musiccast' platform in my hass.
• I have NOT configured any 'yamaha' platforms.

Above logs shows that this error is triggered by discovery component that discovers Yamaha, but incorrectly as old-fashioned platform (RVX- models) and tries to set it up from discovery which fails, because of wrong URL to desc.xml.

What is more – platform is also discovered as dlna_dmr:

[cadavre]

Final thoughts. The problem is actually in https://github.com/home-assistant/netdisco/blob/master/netdisco/discoverables/yamaha.py which wrongly discovers devices as yamaha.

Continuing here: https://github.com/home-assistant/netdisco/issues/248

Sorry for multiple commends one after another.

[mmalina]

Thanks for the investigation, @cadavre . That was my thinking as well - that it's a bug in discovery where it's wrongly discovered as yamaha. BTW as a workaround for this you can exclude yamaha from discovery like this:

discovery:
  ignore:
    - yamaha

I guess it was wrong to close this issue!

In my case the only way to solve this error was by using @mmalina 's hint while doing this ignore thing

`discovery: ignore:

• yamaha`

I updatet my HA just a minute ago, so i guess i'm on the latest version
