rxv Not working with RX-V6A/TSR-700 receiver

Hi! For some reason, rxv doesn't seem to work with the RX-V6A receiver. Is this a known issue?

Dec 10 '20 00:12 borski

Does it work w/ the official app https://play.google.com/store/apps/details?id=com.yamaha.av.avcontroller&hl=en&gl=US?

Jan 19 '21 13:01 wuub

Yes, works without an issue using the Yamaha app

Jan 19 '21 16:01 borski

I assume you've tried to set it up in Home Assistant.

Can you try:

Checking if discovery works

import rxv
rxv.ssdp.discover()

Checking if manual control works

import rxv
r = http://192.168.1.xxx:80/YamahaRemoteControl/ctrl
r.basic_status

Jan 19 '21 22:01 wuub

It does not, and visiting /YamahaRemoteControl/ctrl in a browser returns a 400 Bad Request :(

Jan 19 '21 23:01 borski

When I hit http://192.168.1.xxx:49154/MediaRenderer/desc.xml it spits out the following possibly relevant xml (snipped for relevancy)

<yamaha:X_device>
<yamaha:X_URLBase>http://192.168.1.xxx:80/</yamaha:X_URLBase>
<yamaha:X_serviceList>
<yamaha:X_service>
<yamaha:X_specType>urn:schemas-yamaha-com:service:X_YamahaRemoteControl:1</yamaha:X_specType>
<yamaha:X_controlURL>/YamahaRemoteControl/ctrl</yamaha:X_controlURL>
</yamaha:X_service>
<yamaha:X_service>
<yamaha:X_specType>urn:schemas-yamaha-com:service:X_YamahaExtendedControl:1</yamaha:X_specType>
<yamaha:X_yxcControlURL>/YamahaExtendedControl/v1/</yamaha:X_yxcControlURL>
<yamaha:X_yxcVersion>0945 </yamaha:X_yxcVersion>
</yamaha:X_service>
</yamaha:X_serviceList>
</yamaha:X_device>

and heading to http://192.168.1.xxx/YamahaExtendedControl/v1/ gets me a 200 with the following JSON response:

{"response_code":3}

No idea what this means or if it's helpful, but figured it might be?

Jan 20 '21 00:01 borski

It looks like the receiver is using the same control mechanism and it will be possible to solve this.

Please try the 2nd way of manually instantiating rxv object, it should work (at least partially)

If so, we can then work on testing why SSDP discovery is broken

Jan 20 '21 10:01 wuub

Oh, it does actually work! It didn't previously but it seems to be now!

>>> import rxv
>>> r = rxv.RXV("http://192.168.1.xxx:80/YamahaRemoteControl/ctrl", "RX-V6A")
>>> r.basic_status
BasicStatus(on='Standby', volume=-33.0, mute='Off', input='HDMI2')

SSDP discovery doesn't work:

>>> rxv.ssdp.discover()
[]

Jan 20 '21 17:01 borski

I've also had issues with discovery. When there are multiple network interfaces the discovery packets seem to go out the first interface only. @borski do you have multiple network interfaces in the computer that you're testing on?

If that's the issue, it can be solved by sending discovery requests on each interface. Something like this: https://github.com/pavoni/pywemo/blob/e375e12f4901461b02ceb08feb5c02a766c560ee/pywemo/ssdp.py#L299

Jan 22 '21 03:01 esev

Yes, but the raspi doesn't, unless I'm mistaken? aka Home Assistant should be able to do the discovery just fine.

Jan 22 '21 03:01 borski

@esev I made the change, locally, to force it try each interface; that isn't the issue. Good thought, though!

Jan 22 '21 03:01 borski

Can you look if discovery is working

pip install --user ssdpy
ssdpy-discover -o 20 ssdp:all

and check if the IP of your receiver comes up.

Jan 22 '21 14:01 wuub

I have the same receiver and the same problems with discovery in HA. I tried discovery via ssdpy-discover and it showed up:

{'cache-control': 'max-age=1800',
 'content-length': '0',
 'ext': '',
 'location': 'http://192.168.1.101:49154/MediaRenderer/desc.xml',
 'server': 'Linux/3.2 UPnP/1.0 Network_Module/1.0 (RX-V6A)',

 'usn': 'uuid:9ab0c000-f668-11de-9976-ccd42e2282a6::urn:schemas-upnp-org:service:RenderingControl:1'}

Don't know if that helps!

Jan 28 '21 07:01 this-amazing-amy

@PygmalionPolymorph could you try these three also?

ssdpy-discover -o 20 upnp:rootdevice
ssdpy-discover -o 20 urn:schemas-upnp-org:service:RenderingControl:1
ssdpy-discover -o 20 urn:schemas-upnp-org:device:MediaRenderer:1

upnp:rootdevice seems to be what is being used for the rxv library. https://github.com/wuub/rxv/blob/da90b758da6e1cd5082bd8931f183662e54b1903/rxv/ssdp.py#L21-L27

Jan 29 '21 04:01 esev

FWIW, my RX-V577 responds to upnp:rootdevice, urn:schemas-upnp-org:service:RenderingControl:1 and urn:schemas-upnp-org:device:MediaRenderer:1.

Jan 29 '21 04:01 esev

{'cache-control': 'max-age=1800',

 'x-modelname': 'RX-V6A:CCD42E2282A6:Kino'}

I am getting responses for all 3 of those.

For completeness i tried to run discovery and manual control through rxv. Manual control worked:

>>> import rxv
>>> r = rxv.RXV("http://192.168.1.101:80/YamahaRemoteControl/ctrl", "RX-V6A")
>>> r.basic_status
BasicStatus(on='Standby', volume=-38.0, mute='Off', input='HDMI5')

But discovery didn't work, but unlike @borski i got an error:

>>> import rxv
>>> rxv.ssdp.discover()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/3.8/site-packages/rxv/ssdp.py", line 65, in discover
    res = rxv_details(url)
  File "/Library/Python/3.8/site-packages/rxv/ssdp.py", line 84, in rxv_details
    unit_desc_url_local = res.find(UNITDESC_URL_QUERY).text
AttributeError: 'NoneType' object has no attribute 'text'

The error message also looks similar to the one i originally got inside Home Assistant:

Traceback (most recent call last):
  File "/usr/src/homeassistant/homeassistant/components/discovery/__init__.py", line 196, in scan_devices
    results = await hass.async_add_executor_job(

    for service in netdisco.get_info(disc):

    return self.discoverables[dis].get_info()

    service['X_unitDescURL'][1:])
KeyError: 'X_unitDescURL'

@PygmalionPolymorph Ah! progress :) Thanks for these updates!

Looks like maybe the desc.xml response doesn't contain all the elements that rxv is expecting.

What happens if you modify rxv a bit? Change these lines:

https://github.com/wuub/rxv/blob/da90b758da6e1cd5082bd8931f183662e54b1903/rxv/ssdp.py#L91-L92

To something like this:

    unit_desc_url_local = res.find(UNITDESC_URL_QUERY)
    if unit_desc_url_local:
        unit_desc_url = urljoin(url_base_el.text, unit_desc_url_local.text)
    else:
        unit_desc_url = None

Could you post the response from http://192.168.1.101:49154/MediaRenderer/desc.xml? (the location header in the ssdp response). Feel free to edit/scrub any serial numbers or other identifiers. I think having this as a test case would be helpful in preventing future breakage for this specific device.

Jan 30 '21 21:01 esev

Same issue for me, I have a RX-V4A.

It fails here https://github.com/wuub/rxv/blob/main/rxv/rxv.py#L137

http://192.168.2.148:80/YamahaRemoteControl/desc.xml doesn't returns anything.

I have been able to make it work in HA by changing the unit_desc_url to 'http://192.168.2.148:49154/RenderingControl/desc.xml and returning self in def zone_controllers as it is not able to find the sub units from the xml file.

Feb 11 '21 04:02 william57m

@esev here is the result of http://192.168.2.148:49154/MediaRenderer/desc.xml, I don't see the unitDescURL

@wuub did you make any progress with your new receiver? I have an RX-A6A myself and have been walking a path of issues leading me here 😅 Similar sorts of issues as above - discovery is broken because desc.xml is not quite as expected, but instantiating rxv.RXV by hand with ctrl_url works and I can control the unit via repl. I would love to help figure out a solution here so I can control the receiver through Home Assistant.

Nov 18 '22 20:11 DazWorrall

@DazWorrall I did, by actually using this integration instead https://www.home-assistant.io/integrations/yamaha_musiccast/ because I added more musiccast devices to my home network

Nov 21 '22 11:11 wuub

I saw that integration and initially disregarded it because it didn't think it could control the source input of the receiver, but I dug deeper and found that it can, so it's good enough for my use case 👍

Nov 21 '22 11:11 DazWorrall

Yeah, it's actually more feature rich than this library ever was.

For anyone looking, the source selection is in the usual place:

Nov 21 '22 11:11 wuub

@wuub I'm having the same problem with the Yamaha Network Receivers integration for my RX-A4A. My goal is to use yamaha.select_scene, which the MusicCast integration does not support. Any suggestions?
