I have found the Russound RIO Integration to work quire well with my MCA-88 with one exception. It insists on showing all sources in the Media Player card including those that have been disabled in the MCA-88 web based configuration tool.
Is there some way to get HA to ignore the disabled sources like the Russound App does?
Never mind, being new to Home Assistant I hadn’t yet explored Customizations.
For anyone else new to HA who has a similar question, it appears the Customizations feature opens up a whole new ability to make HA work just the way you want. This feature easily solves my issue of showing only the sources I wish and any of my zones.
Good luck and thanks to the devs for creating such a powerful platform.
