This, by the way, is a handy tip for those with HA servers in homes shared with... Picky people.
I have a timer set up for reboots that don't need to happen immediately. I set the timer, hit go, and it puts this countdown on a bunch of the dashboards. At the end of the countdown, it turns on critical lights (like the bathroom), announces itself one last time, and kicks off a reboot.
Everyone knows it's coming, and the non-working critical lights are on.
Keeps complaints down.
