Chrome cast error when offline

Hardware
1

Hi,

Have a chrome cast connected to a TV and powered via the TV’s USB port, hence if the TV is off the chrome cast is not powered.
In the power offline state, there is no visual indication in HA chrome cast is offline.
If attempting to then switch on the Chrome cast the following error is recorded via the home-assistant.log.
Not a big issue as I can see the TV is off, just something worth mentioning.

First two logs reports the chrome cast is offline at 2018-02-25 22:03:11 I then attempt to switch on the chrome cast.
