Sonos errors (sonos.py) after upgrading to 0.75.2

Configuration

Hi,

I just upgraded to 0.75.2 and am seeing the following errors in the logs:

2018-08-07 14:57:47 ERROR (MainThread) [homeassistant.core] Error doing job: Task exception was never retrieved

    return self._player_volume / 100
TypeError: unsupported operand type(s) for /: 'NoneType' and 'int'

This error is repeated every 10s in the log.

Seems Sonos related, but I haven’t been able to test that (not at home atm).

Thanks.

That looks like your Sonos speaker has become unavailable for Home Assistant.

The verbose error message is a bug, please report more details when you get home so it can get fixed.

I haven’t changed anything and the error was no longer present when I got home.
