Deviceid Configuration

[syedrali]

Hi

under configuration the documentation says "If no device ID is configured, mopidy-gmusic will output a list of registered devices and their IDs." where is this outputted? This is as previously I had deviceid = mac which seemed to work fine but when run in a container gives an error that the mac address can't be obtained so I need to generate a deviceid differently.

This question from @jacobobryant in #221 is related:

Question about the deviceid config key (and the block explaining it in the README). I didn't have to specify a deviceid (I've also verified that playback works), and mopidy-gmusic didn't output a list of registered devices either (as the README says it would). Is the device id bit just out of date and should be removed?

I don't have a GMusic account, but seems like we should verify this and update the docs.

Thanks. Is there any clarification? If you want to run Mopidy in a container where the mac address cannot be obtained, then what value should be used for deviceid?

I came across this recently as well. I'm going to see if I can open a PR around this behavior, but in the meantime you can get the device ID from the Google Music Web UI.

1. Start mopidy without any device ID specific
   • It appears to register a new device automatically when you first connect
2. Visit https://play.google.com/music/listen#/accountsettings and scroll down to My Devices
3. You should see something like No carrier Device
4. Right click on that and inspect the HTML.
   • It should show you a hex value (eg, 0x12345678). Use the part after the 0x

as @syedrali said, there was no output and i wasn't sure where to find it if it did exist. using the "mac" value also failed.

i can verify @thefotios method works. i was having an issue with the device id and no matter what I tried it failed and would output errors.

this was the initial error without setting the device id value:

then i tried using the "mac" value and it gave me the same error as above. after reading this thread and some tinkering i got a new error which was due to the initial hex prefixed at the beginning.

once i removed the prefix from the device id, it was able to load and run.

I am unfortunately facing another unrelated issue with mopidy-gmusic. i'll see if i can find a related thread first and if i do, i'll post it there. if not, then i can always new an issue and post the details there.

Closing because Google Play Music has been shut down, and this project is being discontinued.
