Single point of failure (harmony hub)


It looks that HA is not able to handle single point of failure.

I am building my house automation based on home assistant.
My tests showed me that home assistant is not able to start if configured Logitech harmony hub is not available.
This sounds like a issue in HA because single point of failure (harmony hub in my case) prevents HA to start correctly. GUI is not available and all configured smart home components doesn’t work.
