Restarting Home Assistant pauses Print

[edalquist]

I'm not really sure how or why but I'm experiencing a situation where when I restart Home Assistant my print pauses.

@edalquist do you have Automatically turn PSU ON enabled?

[edalquist]

I did have that option on, I missed it in the original readme. Does that cause the printer to pause when HA becomes unavailable?

[edekeijzer]

@edalquist since it tries to turn on the printer, it will wait for the printer to turn on. PSU Control initially just supported GPIO pins, which can't really go offline during a print. Home Assistant can, as well as pretty much every external power switch supported by PSU Control plugins.
I'll emphasize this warning even more, since you're surely not the first who mentions a stop or very slow response from Octoprint when HA becomes unavailable.

Interesting, so is the underlying issue in the parent PSU Control plugin not handling unavailable switches gracefully?
