Supported_media_commands problem

I have created a new component for musiccast devices. I can pause, stop and resume playback from the service call page. But I do not see any start, volume button in the frontend.

I suspect this is the issue:
supported_media_commands: 0

I cannot see any reason for this behavior in my code:

I struggled on this one too… You have to implement supported_features() like this: https://github.com/jalmeroth/hass_yamaha_multicast/blob/master/yamaha_multicast.py#L80-L83

Hope this helps…
