Snapcast not deploying

gpratas · April 21, 2016, 6:15pm

Hi,

I’m testing snapcast media server component with snapcast server version 0.6.0 using the following configuration:

media_player:
- platform: snapcast
  host: 192.168.1.244

But when deploying home assistant, the snapcast component doesn’t appear and I have the following errors in the home-assistant.log file.

Thanks.

Snapcast component currently works with snapcast 0.5.0. I think 0.6.0 made some kind of incompatible change. I can take a look tonight.

gpratas · April 22, 2016, 7:40pm

Hi. Thanks for your answer.

I’ve tested also with version 0.5.0 and the behavior is the same.

Rgds.

happyleaves · April 22, 2016, 10:16pm

I’m currently testing and updating the component for snapcast 0.6.0. It does have a different configuration.

happyleaves · April 24, 2016, 6:44pm

You can pull this branch if you want to test the update: https://github.com/home-assistant/home-assistant/pull/1908 prior to release.

gpratas · April 24, 2016, 7:05pm

Sorry to ask. But how do I do that? I’m a power user but still not a programmer

gpratas · April 24, 2016, 9:33pm

I’ve copied the file directly to the respective folder and tested it.

Results:

The snapclient’s appeared in the interface;
Client name’s don’t appear even when configured in the ~/.config/snapserver/server.json, always appear “Unnamed Device x”;
Play/pause don’t work;
Volume and mute worked ok.

happyleaves · April 24, 2016, 10:47pm

Play/pause will not work. There is no such concept in the snapcast world. A client is either receiving the stream “playing”, or not, “idle”. And that is controlled by the stream source.

Make sure you are changing the name value under config, not, snapclient. Also, make sure the snapserver is not running when you make the change, otherwise it will be overwritten.

gpratas · April 24, 2016, 11:16pm

Hi, thanks for the reply. I understand now the play/pause will not work, so they should appear in the interface, since the user will try to click it.

Regarding the ~/.config/snapserver/server.json it looks like this.

Can you tell what might be wrong?

I agree that the interface should not show UI that you can’t use. I am only the developer of the backend component though, I don’t know much about the media player front end. I think there is some discussion of a separate UI for AVR-type devices (like receivers – essentially what snapcast is).

Your configuration looks fine. Its possible you may have to restart server and clients, but I’m honestly not sure. If you look at the output of snapserver, do clients connect with the configured name?

gpratas · April 25, 2016, 8:54am

The output of the snapserver is the following:

Hi,

Probably you didn’t had time to look at it again. BTW, the attribute “name:” is not working for snapcast platform,.

I wanted to create a group with all the media servers, but when I state the entity name: of the snapcast, it doesn’t appear.

Thanks.

Rgds.

Simon_Ku · March 12, 2017, 6:56pm

I am sorry for the stupid question, but do i have to put the adress of the snapcast server or client in the host field? I see this in the logs

File "/home/homeassistant/.homeassistant/deps/snapcast/control.py", line 349, in _transact
    raise Exception('No response received')

HVPereira · April 22, 2017, 6:17pm

It is not a stupid question I am having issues on configuring snapcast on HASS as well. Does anyone have any idea to support me and @Simon_Ku

happyleaves · April 22, 2017, 6:36pm

HASS does not currently support 0.11, so keep that in mind.

What error are you receiving?

vrs01 · May 19, 2017, 4:40pm

Hi! I use snapcast 0.11.1 and get the following error in hass:

0.11.x is not supported yet. Hopefully next version.
