Thanks jgus. PR for fix was submitted.

Not sure if this is the same issue, sharing and interested in feedback if I should open a new Issue.

I am seeing the JVC integration going greyed out after using it a few times.

Logs give me a warning:
Logger: jvcprojector.command
Source: components/jvc_projector/coordinator.py:46
response '' not int for cmd 'SC'

and I also have a long Error:

Note that the Projector itself is still having proper LAN connectivity, so is the rest of the HA server.

[SteveEasley]

This looks like a new issue. Would you mind creating a new one, including the projector model you are using?
