Just had this start popping up on my system 0.117.6

Detected I/O inside the event loop. This is causing stability issues. Please report issue for nest doing I/O at homeassistant/components/nest/__init__.py, line 480: for structure in self.nest.structures:

Completely took HA offline.

All Nest features unavailable.

[Arjenlodder]

Same here.

[oweijers]

Same here.

But if we're all completely honest: It's a badly supported device, which doesn't even succeed in it's main function: to properly read out the room temperature. Always 1/2 degrees to high (because the wifi chip heats the internals)

It's time to take this beautiful looking failure from the wall.

Nice hardware, deplorable software.

edit: Nest service seems to be down.

The only thing I can blame on home-assistant, is that this seems to mean that a failing nest-service can completely kill home-assistant as well.
