Slow state update for yamaha_musiccast

[Kernald]

The problem

Very similar to what's been described in #79148: actions from Home Assistant to MusicCast devices are virtually instant, but getting the state changes (either from HA or from the MusicCast app) back to HA takes up to a minute. Unlike #79148 however, I do not have HA running in a container, there shouldn't be any network restrictions in place.

Additional information

Nothing in the logs (even in debug) when the integration is loading, as far as I can tell - just the above logs once every minute for all my MusicCast devices.

[micha91]

Which musiccast devices do you own? Did the device discovery work for you or did you add the devices manually using their IP?

[Kernald]

I have a few:

• WX-030
• WXC-50
• CD-NT670
• TT-N503

As far as I can remember, they all got auto-discovered, but it's been a while.

[micha91]

Sorry for the late response - are you running the HA Container in Host mode? We use a UDP connection to send update from the MusicCast device to HA and therefore we open a dedicated port in HA per MusicCast device. This will most likely work in host mode only

[Kernald]

No worries - I appreciate the help. I'm not using HA in a container, but rather bare metal. I suspect this might then be a firewall issue - is there a specific port or range that this uses?

[Kernald]

For what it's worth, disabling the firewall entirely indeed fixes the issue - but that's obviously not a solution. Opening the different ports listed by Yamaha (UDP 1900, UDP 5353, UDP 51100, UDP 51200, UDP 61100, TCP 80, TCP 49154, TCP 51000) doesn't solve it either. It would be really helpful knowing what port(s)/range the component relies on.

Edit: it seems that asyncio.DatagramProtocol is used and just picks a random UDP port. It would be great to at least restrict it to a specific range.
