Graceful Error handling if a machine is unavailable at the point in time of a HA reboot

[Shredder5262]

I see these errors in the logs and the Hass.Agent integration produces an error for the machine if the machine is unavailable at the point in time of a reboot. In my opinion a method of error handling needs to be accounted for in these types of situations in the integration As the integration will display an error that isn't a true failure because the machine is not on after a reboot...to correct this at present it means that i would have to start up several machines simply to clear the error.

This error originated from a custom integration.

To fix this in the mean time you can use MQTT as it doesn't require any api calls on bootup. I will look into a solution for the error though.
